This has been very popular previously and now Banggood are selling 3 on sale with the coupon. The cost of 3 ends up being cheaper than 1 from Xiaomi Australia.

These monitors will display the current temperature/humidity and can be linked with other Xiaomi smart home products via the Mi Home app. It also has a "baby monitor" mode where it will send you an alert through the Mi Home app when the temperature and humidity go too high or too low.

For those who are into tickering there is a custom firmware project for this too.

    Great devices. I ended up using the github repo linked off the one in the description: https://github.com/pvvx/ATC_MiThermometer

    • Clear on 12/08/2021 - 19:44

      Ah a much better one. Updated.

    • VehemenceThePhoenix on 12/08/2021 - 22:39

      Smoothest custom flashing experience ever too.

    • DemoMan on 13/08/2021 - 10:13

      Apologies for the noob question . In order to get these devices talking to home assistant , do I require a hub or something like that ? I have my home assistant running on a Rasp Device at present and all wifi devices are connected to it .I have not really tried a Bluetooth device vefore.

  • Bargain-er on 12/08/2021 - 19:45

    Can work with other brand or only xiaomi?

    • Namidairo on 12/08/2021 - 20:04

      The stock firmware encrypts the beacons, so you'll probably want to flash it with something like https://github.com/pvvx/ATC_MiThermometer

      Then after that you can link them up to your Home Assistant instance with https://github.com/custom-components/ble_monitor (I'm assuming a Home Assistant instance with access to bluetooth. You could alternatively stick ESPHome on a ESP32 and use that.)

      Or you could just keep it on your wall and look at it. That's good too.

      • lysp on 13/08/2021 - 11:17

        I just did this to 8 of these last night.

        Very easy process. Took about 2-3 minutes per device.

        Couldn't get it working via my PC Bluetooth (which would have been quicker), but worked fine on my phone.

        Basic Process:

        • Run firmware website
        • Pair
        • Activate
        • Upload firmware
        • Re-pair
        • Turn face off
        • Set clock
        • Name device
        • Save config

    You should probably put the model name in the description somewhere, they have a few Xiaomi branded thermometers with different screen types etc. (This one is LYWSD03MMC )

    The range and battery life on these models are worse than they should be, due to Xiaomi cutting corners on the design. (They omitted placing a couple capacitors on the board, despite the PCB design having pads already for them.)

    You should be able to disassemble it and solder them on, if you want. However, if you're opening them up anyway you could just add one of those tiny panels and a supercap, like one of those calculators. (https://hackaday.io/project/177910/instructions)

    • Clear on 12/08/2021 - 19:56

      Or just look at the pictures to see it's different or even read the BG product page which you should do anyway before buying. Technically speaking there are Xiaomi, Qingping and Miaomiaoce. Unfortunately the latter 2 are incorrectly called Xiaomi.

      It does, but it takes a few minutes to pull up the history via Bluetooth which can be a bit of a pain (I'm not using any other gateway and just directly connecting to them via the app)

    I found these useless for automation out of the box. They seem to only check in with the Xiaomi hub when you open the mihome app and select the sensor. Pretty disappointed with them (bought in a previous deal). They're a nice neat little unit if you just want to read the display though.

          Build dashboards based on the data coming from the sensors. I bought 4 from the last deal and built this in Home Assistant. All from the sensors except the 'BOM' and 'Wind' cards. This is just one of the tabs I have showing on a wall tablet.

    I got this. Turned out to be a Chinese version as in the manual was entirely in Chinese. Tried to look up online on how to pair it with Mija home app but didn't work. Somehow it doesn't work if we select region as Australia as server for Mija home account. So just using it as non BT temperature reader. Anyone else managed to pair it smoothly?

        Tried that too but no luck. It said device may be already paired so tried resetting it but that didn't help either. At this price point, its not too bad even just as non BT sensor but just wondering if anyone else managed to pair it successfully.

    Are these better than say, these Aqara ones

    Other than the lack of screen, and Zigbee vs Bluetooth.

    • Clear on 13/08/2021 - 16:51
      +2

      Aqara is certainly better for smart home integration given the use of Zigbee. This Xiaomi is more suitable for having a physical display you can see.

      • jwh on 13/08/2021 - 20:59

        Thanks, I seem to have constant connection issues with the Aqara ones though, connected to an older Aqara camera hub.

        Doesn't do much if connected directly to my Echo Plus over Zigbee either.

        Was hoping something like these would just 'work', and link with Alexa/Google Home easily. Don't think that's the case though.

  • nosrad on 08/09/2021 - 22:16

    After cracking the firmware, can the Nest Hub Max be used as a Bluetooth gateway? If not, what's a popular BLE?
