Convert Xiaomi LYWSD03MMC From Bluetooth to Zigbee


UPDATE 13.11.2023: The Qingping Temp & RH Monitor LITE CGDK2 [AliExpress] and the MiaoMiaoCe Temp & RH Monitor MHO-C122 [Webstore] have received Zigbee support! Follow these instructions to flash.

As some of you know, I’ve been testing and reviewing Zigbee temperature and humidity devices for a while now, recently culminating in a summary article comparing 10 of these climate sensors with a display. This was an effort towards finding out which ones are worth our money and which are not.

Even though I’ve accumulated more than 15 different models, I never actually used Zigbee-based temperature sensors in my home. I’ve always relied on Xiaomi BLE devices (Especially the LYWSD02 and CGG1), whose packets I capture with ESP32 boards.

Convert Xiaomi LYWSD03MMC BLE to Zigbee: Featured Image

In this article, I’m going through the process of flashing a Xiaomi Sensor (LYWSD03MMC) with Zigbee firmware and integrating the device in Zigbee2MQTT and Home Assistant.

About the LYWSD03MMC

The LYWSD03MMC is a BLE (Bluetooth Low Energy Sensor) manufactured by Xiaomi, which relies on the Telink TLSR8258 [Datasheet] MCU. The Telink chips used in these devices can be flashed with custom firmware which unlocks several customization options, better battery life, better accuracy of measurements and LCD display information looping.

Currently the pvvx custom firmware supports the following models:

  • Xiaomi (LYWSD03MMC)
  • Xiaomi (MJWSD05MMC)
  • Qingping (CGG1)
  • Qingping (CGDK2)
  • Xiaomi MiaoMiaoCe (MHO-C401)
  • Xiaomi MiaMiaoCe (MHO-C122)

The LYWSD03MMC is a square model with a small LCD display, powered by a single button cell CR2032 battery. With it’s default firmware, it publishes it’s readings via BLE once every 10 minutes. By using the custom pvvx firmware, the interval can be changed to report more frequently.

The Zigbee custom firmware for this device was developed by Ivan Belokobylskiy (devbis) and can be flashed OTA (Over-the-Air) or with an USB-to-TTL adapter. In this article, I’m going over the OTA method as it’s easier and doesn’t require dismantling the device and soldering wires.

Converting the LYWSD03MMC to Zigbee 3.0 (OTA)

First, you need to #enable-experimental-web-platform-features in Chrome, Opera or Edge. This is necessary in order to get the MAC Address of the device. Copy the following links for the browser you use and paste it into the address bar:

  • Chrome: chrome://flags/#enable-experimental-web-platform-features
  • Opera: opera://flags/#enable-experimental-web-platform-features
  • Edge: edge://flags/#enable-experimental-web-platform-features
Enable Experimental Web platform features on Chrome

Restart your browser. To flash the LYWSD03MMC, carefully follow the procedure bellow.

  1. In your browser, navigate to https://pvvx.github.io/ATC_MiThermometer/TelinkMiFlasher.html
  2. Check Get Advertising MAC and click Connect
  3. Select the LYWSD03MMC from the list of Bluetooth devices and click Pair

    Convert Xiaomi LYWSD03MMC BLE to Zigbee: Step 1 - First Connection
  4. Wait for the connection to be established
  5. Press the Do Activation button and wait
  6. Download the transitional firmware file ATC_ota_40000.bin
  7. Select the file by clicking Choose File

    Convert Xiaomi LYWSD03MMC BLE to Zigbee: Step 2 - Activation and Flashing Transitional Firmware
  8. Press Start Flashing and wait for the process to finish.

WARNING: Flash the transitional firmware even if you are already on custom firmware! Failure to do so make brick your device and you will need to use USB/UART to re-flash it.

Once the transitional firmware if flashed, take out the battery of the Xiaomi LYWSD03MMC and wait 15-20 seconds. Reinstall the battery and wait for the device to boot up again.

  1. Navigate to the Zigbee version of the Telink flasher
  2. Press Connect again only this time the device name will be different (e.g. ATC_XXXXXX)

    Convert Xiaomi LYWSD03MMC BLE to Zigbee: Step 3 - Reconnection
  3. Press Pair
  4. Download the latest z03mmc.bin Zigbee Firmware file:
  5. Click Choose File and select the z03mmc.bin
  6. Press Start Flashing and wait for the process to finish

    Convert Xiaomi LYWSD03MMC BLE to Zigbee: Step 4- Final Flashing

The process can take somewhere between 4-5 minutes and it will log Update done after XXX seconds in the console. Done!

Converting using UART

Wires are always better than wireless, so if you encounter issues while flashing you can always use UART to flash the Xiaomi LYWSD03MMC Sensor. However, the process is a bit more involved and requires soldering. Follow the guide described on the official repository to flash via USB to UART.

Pairing the LYWSD03MMC to Zigbee2MQTT

The Xiaomi LYWSD03MMC was added to Zigbee2MQTT with version 1.33.2, so if you do not want to use an external converter make sure you update. Here’s how to use the external converter in case the device is unrecognized:

  1. Create a new file in zigbee2mqtt folder (next to configuration.yaml)
  2. Name it lywsd03mmc.js (make sure it ends with .js)
  3. Open the file and copy the contents from bellow:
const fz = require('zigbee-herdsman-converters/converters/fromZigbee');
const exposes = require('zigbee-herdsman-converters/lib/exposes');
const reporting = require('zigbee-herdsman-converters/lib/reporting');
const ota = require('zigbee-herdsman-converters/lib/ota');
const e = exposes.presets;

const definition = {
    zigbeeModel: ['LYWSD03MMC'],
    model: 'LYWSD03MMC',
    vendor: 'Xiaomi',
    description: 'Temperature & humidity sensor',
    fromZigbee: [fz.temperature, fz.humidity, fz.battery],
    toZigbee: [],
    configure: async (device, coordinatorEndpoint, logger) => {
        const endpoint = device.getEndpoint(1);
        const bindClusters = ['msTemperatureMeasurement', 'msRelativeHumidity', 'genPowerCfg'];
        await reporting.bind(endpoint, coordinatorEndpoint, bindClusters);
        await reporting.temperature(endpoint, {min: 10, max: 300, change: 10});
        await reporting.humidity(endpoint, {min: 10, max: 300, change: 50});
        await reporting.batteryVoltage(endpoint);
        await reporting.batteryPercentageRemaining(endpoint);
    },
    exposes: [e.temperature(), e.humidity(), e.battery()],
    ota: ota.zigbeeOTA,
};

module.exports = definition;
Code language: YAML (yaml)
  1. Save the File
  2. Open Zigbee2MQTT’s configuration.yaml file (NOT Home Assistant’s)
    • Location of the file is zigbee2mqtt/configuration.yaml
  3. Enable the external converter by adding the following lines:
  4. Restart Zigbee2MQTT and pair the LYWSD03MMC
external_converters:
  - lywsd03mmc.js
Code language: YAML (yaml)

Once the LYWSD03MMC is powered up initially, it will automatically enter pairing mode. If not, you can use a short piece of wire of something metal to short the RESET and GND contacts for 3 seconds.

Convert Xiaomi LYWSD03MMC BLE to Zigbee: Pairing Mode

Once the device gets discovered and paired in Zigbee2MQTT, it will be identified as an EndDevice by manufacturer Xiaomi and model LYWSD03MMC.

Pairing the LYWSD03MMC to ZHA

Once flashed, the device works with ZHA in Home Assistant without the need of any custom quirks. Remember to short the RESET and GND contacts for 3 seconds to enable pairing mode. Once paired, it identified as LYWSD03MMC by Xiaomi as an EndDevice.

About Battery Life

Since most people are wondering how battery life is affected on the Zigbee firmware compared to the original BLE firmware, developer pvvx wrote a short paragraph explaining his findings:

“The final average consumption of LYWSD03MC B1.4 when measured from a 3.3V source is from 14 to 26 µA, depending on the dynamics of changes in temperature and humidity. For comparison, the BLE version consumes 14 µA with default settings and constant transmission of all measured values ​​every 10 seconds.”

It’s safe to say that even though battery consumption is higher on the Zigbee firmware, in reality it will be affected very little compared to the default setting of the BLE version.

Final Thoughts

UPDATE 13.11.2023: The Qingping Temp & RH Monitor LITE CGDK2 [AliExpress] and the MiaoMiaoCe Temp & RH Monitor MHO-C122 [Webstore] have received Zigbee support! Follow these instructions to flash.

Converting the Xiaomi LYWSD03MMC is useful for people who want to use Zigbee devices exclusively in their smart home. Props to Victor (pvvx) for forking and developing the original ATC Thermometer firmware and Ivan Belokobylskiy (devbis) for developing the Zigbee custom firmware.

The device reports every 5 minutes in Zigbee2MQTT and ZHA, pushing the temperature and humidity reading with a precision of two decimal places. You can create an offset in Zigbee2MQTT if needed and calibrate the measurements.

Remember, you will not be able to reconnect to the device with the Telink flashed since there is no Bluetooth firmware installed anymore. You can use Zigbee2MQTT’s OTA update feature to flash and update the LYWSD03MMC again if you need to.

Fahrenheit support is not yet available with the custom firmware, the dev added a PR on the official repo so it should be coming soon.

For those of you wondering whether this will be possible for other Xiaomi sensors based on the Telink MCU: Yes, in theory it is, although there is no development at the moment.

You can get the Xiaomi LYWSD03MMC on AliExpress and Amazon.

  1. Wow, what a great way to improve the usability of these cheap sensors! The guide worked perfectly, although I did have to create the external converter (even on Zigbee2MQTT 1.33.1), since it first reported as unsupported.

    Also, it seems the “interview was not completed”, but I still get temperature and humidity data. To be fair however, I use a very basic CC2531 Zigbee sniffer (using router firmware) and have 46 Zigbee devices, which may be stretching its capabilities quite a bit…

  2. I have 3 of these devices but I cannot connect them even to the first page. It sees my MAC Address, i pair with the browse on that page and it tries do connect 5 times and then i get a message “connection Error” and then “Something went wrong, to many reconnects”. I have enable the experimental-web-platform on Chrome. All of them are on custom firmware. I don’t know what i’m doing wrong. But great step by step info. Thanks

  3. Worked like a charm.
    Thanks for the detailed description.
    Also had to create the external converter but after that it was smooth sailing.
    Do you have any idea about battery life ?
    Nice tutorial
    Thank you

    1. Still early to tell, but going by my experience with Zigbee and BLE Sensors, I would guess about 20-25% lower battery life on the Zigbee firmware.
      The custom firmware does bring some battery optimization though

  4. If you live in densely populated areas, I recommend flashing while in the basement/cellar or even going to a park or in the woods.
    For me, flashing these thermometers with ATC firmware worked much, much better while in the cellar.
    Personally, the only advantage I see for ZigBee is the relaying of the network (my Pi4 could be better hidden away). Otherwise, if the reports are every 5 minutes, irrelevant if the values change, it would make my bathroom fan automation almost useless.

  5. Hi!
    Flashing goes well. but when goes my zigbee2mqtt > there shows those are unsupported and can´t see temperature etc

    Device type
    EndDevice
    Zigbee model
    LYWSD03MMC
    Support status
    Unsupported
    Made that:
    Create a new file in zigbee2mqtt folder (next to configuration.yaml)
    Name it lywsd03mmc.js (make sure it ends with .js)
    Open the file and copy the contents from bellow:
    And configuration.yaml too.

    any thoughts?

    1. Make sure you stop Zigbee2MQTT
      Open the Zigbee2MQTT folder
      You will see configuration.yaml file inside (NOT Home Assistants’s configuration.yaml file)
      Add the code. Restart Zigbee2MQTT

  6. Tried with two of mine. Flashing seemed to be completed fine. Ended up with 3 dashes and the little bluetooth icon on the sensor, but seemed stuck. After getting the battery out and in, nothing happens anymore 🙁

  7. So.. i manage to brick my sensor. After the flashing was finished ( step 14.) the sensor turned off and it won’t turn on.. Any suggestions how to bring it to life?

      1. Battery is not a problem ( connected to external DC power supply).
        And i did get the “Update done after XXX seconds”..

        1. I got the same problem, I’m using a fresh duracell battery, so it can’t be any issue there. All seemed to go fine, then I got “Update done after 185 seconds”, but the sensor went blank and won’t respond. Maybe latest firmware has issues?

  8. Very nice tutorial! Amazing and straightforward.

    Just a little issue at the beginning, because I used ‘Save Link As…’ directly from the link above and downloaded a 352KB binary file, which turned out to be the GitHub HTML saved as a .bin file. I realized there was an issue with the file when the firmware upload tool displayed a popup message saying, ‘Size firmware is more than 131,072 bytes.’ I finally downloaded the file directly from the GitHub repo, and it was 80.6KB, which was correct.

    Currently, I have configured one out of my 12 devices for testing this new Zigbee implementation. I’ve placed this test device next to an identical Bluetooth device for comparison. Additionally, I have replaced the batteries in both devices with batteries from the same brand and pack (100% capacity) at the same time to compare the difference in terms of battery consumption over the long run. I will also compare the value reporting to see if they look similar.

      1. Already, after just 3 days, I’ve noticed a significant difference. While my Bluetooth thermometer has dropped to 94% of its battery life, my Zigbee device remains at 100%, which is a bit surprising. Now, the question arises: could there be a difference in the percentage calculation between the Zigbee and Bluetooth implementations? A 6% decrease in 3 days seems quite significant, and I would have expected Zigbee to consume more energy which is the total opposite.

        1. Hey Vincent,

          Battery reporting is wildly inaccurate in these types of sensors, no matter the firmware.
          It is calculated on voltage and is actually an approximation, it’s not an exact percentage.

          Zigbee should and will consume more battery, so just give some time to stabilize.
          My estimate suggest around 15-20% shorter battery life on the Zigbee firmware with a 5 minute reporting rate.
          Which should still make it last 8+ months on a good battery.

          Cheers

  9. I flashed one sensor for testing, work like a charm with zigbee2mqtt.
    I’ll compare the measurements with other one in bluetooth.
    Thanks for this article !

  10. i have installed the firmware on mine, this went ok. But know i can not connect it to zigbee2mqtt. I have created the external converter.

    I tried to short it with an copper wire, but it does not like to do anyhting.
    What can i try?

    1. 1. Take out the battery for 10-15 seconds
      2. Click Permit Join in Z2M
      3. Put the battery in place
      4. Wait for it to pair, if not short the GND and RESET for 3 seconds

      1. Same problem here. First device works like a charm after flashing. Second one device flashed without problems also, but it cannot enter pairing mode. Removing battery and GND + RESET is not working.

          1. You might have to use UART, seems like OTA flashing soft bricked it.
            Possibly due to low battery.
            You can use USB-UART and flash it without problems

  11. Hi, Thanks for the detailed steps. Unfortunately, I get the following when trying to flash the transitional firmware – any suggestions?

      1. yes, first atc.ota.40000.bin, then zigbee, but it failed, the thermometer disconnected. Unable to pair now. I’ll try the ttl method, but I don’t really understand it

      2. Yes – but have managed by repeatedly reconnecting managed to get devices flashed. It is the transitional firmware that I was having trouble flashing – the zigbee firmware always flashed first time OK. If the transitional firmware failed it was either at block #7, or the block number were increasing very slowly. Once the firmware had got passed block #7 – and the block count increased rapidly it would always work.

  12. I realized that the battery voltage is not exposed from the Zigbee state. To expose the battery voltage, I made a simple modification to the lywsd03mmc.js file :

    Original: exposes: [e.temperature(), e.humidity(), e.battery()],
    Modified: exposes: [e.temperature(), e.humidity(), e.battery(), e.battery_voltage()],

  13. Thanks for this. Got it working on 2 devices. Battery life is horrible with zigbee. I had a new battery with 100% reporting for a day. Today after around 5 days, it’s at 65%. So going by that it will only last for 12-15days max.

    Other sensor had around 60% battery on start, currently at 11% after 5 days. So around 8-10% drain a day. totally not acceptable.

    What are other’s findings?

    1. As I mentioned in another comment, Battery reporting is wildly inaccurate in these sensors no matter the firmware.
      They calculate the percentage left based on voltage, which can fluctuate.

      Give it some time to stabilize and see if it really is draining that much.
      My estimate is about 20-25% shorter life span of the battery with the Zigbee version but not what you are suggesting.

      Cheers

    So, I had problems with connecting for the first part, but eventually was able to flash the transition firmware. The device now appears as ATC_0E2D7B, but even after 6-8 reboots, and restarting the browser, etc, I am not really able to get it to connect to the ATC “version”. It shows up as unpaired, but never connects, just:
    Status: Connecting to: ATC_0E2D7B …
    Temp/Humidity: waiting notify for data after connecting
    and in the log:
    15.11.58: Searching for devices
    15.12.03: Connecting to: ATC_0E2D7B

    Any hints from anybody?

    1. Clear the cache or use another browser.
      Do you have others BLE devices in close proximity? Eliminate interference for the time being and test.

  16. Hello,
    I flashed mi device using UART. After that, I connected it via ZHA, but I only receive information at the time of linking. After that, the device not notifies changes via Zigbee

    Is there any way to downgrade the firmware of the device or wait for Telink to support this version?

    Fortunately, I had some other device lying around that I had not upgraded, and I had successfully converted it to Zigbee.

    I had to add the external converter because of some troubles with zigbee2mqtt upgrade.

    Thank you very much!

  18. I went back to ATC4.4 via the ttl converter, the thermometer works again. As soon as I upload the ATC40000, it’s over and the thermometer refuses to connect. Would it be possible to elaborate a bit on how to upload the zigbee variant via TTL, thank you

  19. good morning,

    fortunally i can connect again with the device, but how can i solve? i installed before the ATC_ota_40000.bin firmware

        1. None at the moment, although I believe every Telink device can theoretically be flashed to Zigbee.
          Seems like the TH05 model you have uses encrypted BLE advertisements. It can be done, but understandably no one has interest in bothering with it.
          Your best bet is local tuya w/hub. 🙂

  20. Can confirm the transitional firmware step is important as bricked two out of 7 OTA, not an issue for me as done via wires now but still should have done it (found this guide after I had done it)! Worth noting that there is a report of an issue with bluetooth devices such as these connected to homeassistant using an SSD wearing out the SSD quite quickly as constant writes of a small file, this zigbee approach prevents that so seems like a good approach if true. Also makes my Z2M map look more fun

  21. Hello. Is it possible to change the “MHO-C303” model to zigbee?? It is a product with a clock and a thermo-hygrometer, and the guide description shows as follows.

    Hygro thermometer clock with alarm, rectangular body, e-ink display, broadcasts temperature, humidity and battery status. Not encrypted.

    Similar to the LYWSD02, with additional clock features (alarm, pomodoro timer). Runs on two AAA batteries.
    -redacted-

  22. If you can’t connect, please disable extensions in the browser like ublock origin. Without disabled i can’t connect. After that it goes a lot more smooth. But also needed reconnect 1 time.
    Just amazing devices are these small Xiaomi sensors. Lot of features and very precise. Hope there comes a lot more functionality in the firmware so you can configure it like the PVVX firmware. So enable and disable smile, battery status on display, update interval and so on.

  23. Hi
    I have flashed one of my LYWSD03MMC with the zigbee firmware and it worked also a few days with my sonoff Dongle-E and ZHA in home assistent.
    But now my ZHA network no sees the LYWSD03MMC anymore.
    An shorting grd and reset also not set it to pairing mode.
    I cant add the LYWSD03MMC to my network.
    So what can i do now?

  24. This looks as wonderful project, thank you for all the effort. However I am trying to flash the transition firmware, getting the message “Incorrect head in Telink OTA binary firmware”. Seemed simple but still I am doing something wrong. 🙂

  25. Hi
    Do you know if it’s possible to do the same in jeedom
    In jeedom, in the zigbee2mqtt folder, there is no configuration.yaml file… Thanks

    1. No, I am not really familiar with Jeedom.
      The external converter is fairly new, so I guess you would need to adapt it to Jeedom in order to use it.

    2. Thanks a lot for your page. 🙂
      For Jeedom, you don’t need an adapter, BUT you must update dependencies on JeeZigbee plugin parameters page, to have at least zigbee2mqtt >= 1.33.1.
      You can find version of ZigbeeMqtt on “zigbee network” on JeeZigbee gestion page.

  26. Hello, having issues to connect to a new device, it’s the first time I try this:

    16:23:36: Connecting to: LYWSD03MMC
    16:24:14: MiVer5, DevID: 0x055B-LYWSD03MMC, FnCnt: 1, CtrID: 0x5830 Not bound, Standard certification, MAC: A4C1386E458A, Capability: 0x28 – front binding, IO: 0x0001
    16:24:21: Not found Telink UUID service!

    anything I’m doing wrong?

  27. Fantastic, just flashed 2 of them and zha picked them up right away!
    I have been having Bluetooth issues and passing the Bluetooth device through to a vm of HA and this has now solved it.

    Thanks very much

  28. My devices is flashed with the BLE firmware from ATC (https://github.com/atc1441/ATC_MiThermometer) and comes back with the following
    09:55:14: Searching for devices
    09:55:26: Get Advertising MAC (Web Experimental Features!)
    09:55:26: Connecting to: ATC_5456FA
    09:55:26: MAC: A4C1385456FA, Bat: 79%, Vbat: 2921 mV, Temp: 18.3°C, Humi: 65%, Count: 26
    09:55:36: Not found Telink UUID service!
    09:55:36: Disconnected.

    Is there something that can be done here?
    Thanks in Advance

  29. this flasher https://pvvx.github.io/ATC_MiThermometer/TelinkMiFlasher.html results in :
    13:54:23: Searching for devices
    13:54:48: Get Advertising MAC (Web Experimental Features!)
    13:54:48: Connecting to: ATC_6E0752
    13:54:51: MAC: A4C1386E0752, Bat: 72%, Vbat: 2863 mV, Temp: 18.2°C, Humi: 64%, Count: 20
    13:54:53: Not found Telink UUID service!
    13:54:53: Disconnected.

    So it connects to the device, retrieves bat/temp/humi/etc info but then disconnects.

  30. Thx for the Zigbee2MQTT yml instructions! Couldn’t pair without this.

    Pairing tip: put Zigbee2MQTT in pairing mode while at the end of your flashing. Then the device will be automatically paired, without you to remove the battery.

  31. I flashed 3 devices, the first two I had no problems, but the third now is stuck. It looked OK, but after flashing the z03mmc.bin firmware, the screen is ON but it doesn’t refresh the temp/humidity anymore and it doesn’t connect to Zigbee2MQTT. If I take the battery, it refresh the temp/humidity just once, it blinks the screen once, and then nothing…

  32. Hi all, I converted successfully 3 devices but the battery consumption is too high compared with other devices. I’ve a switchbot ble temperature devices that is at 100% battery after few months while the converted xiaomi zigbee device was dropped to 90% after one week.
    Could you shared the steps to return to ble firmware?

    Regards

  33. I have the newest firmware on my xiaomi sensors, and after pairing the flasher recognises it and automaticly disconected with incompatibly problem.

  34. I just flashed my Mi Thermometer, but it displays only Temp, no humidity/battery:

    MQTT publish: topic ‘zigbee2mqtt/Mi Temp 5’, payload ‘{“battery”:null,”humidity”:null,”linkquality”:80,”temperature”:27.68,”update”:{“installed_version”:-1,”latest_version”:-1,”state”:”idle”},”update_available”:false}’

    I used new sensor.

    Is there any way to fix this?

  35. That’s awesome!
    Just a question: will I be able to connect the Zigbee-converted device with the XIAOMI Mijia Smart Multi-Mode Gateway ZigBee/WIFI/Bluetooth?
    Thank you,
    Luca
