Support for Xiaomi Mijia Bluetooth Temperature

[robotsflo]

Hi, Can you please add support for Xiaomi Mijia Temperature ? Or create a new " mitemp-mqtt-daemon " repository. Thanks a lot for your good job !

Please add it as a feature, my dear friend.

[tunip]

And how do we add this as a feature? I like this project for my Mi Floras and have 6 of this MiTemp devices in the house.

+1

[cropab]

+1 there is no mijia mqtt solution for the raspberry pi.

[sendorm]

+1 to this too.

You can test this https://github.com/aqualx/miflora-mqtt-daemon/tree/mitempbt If test succeed I'll make PR.

I am getting this error with your code: ImportError: No module named 'mitemp_bt' which is fixed with sudo pip3 install mitemp_bt :)

But keep getting: The MAC address "xx:xx:xx:xx:xx:xx" seems to be in the wrong format. Which is the mac address of the mitemp sensor.

[aqualx]

_mitempbt added to requirements.txt. So this will install all needed packages:

sudo pip3 install -r requirements.txt

Which MAC address has your sensor? You have sensor with screen or without? I have two of them and both start from "4C:65:A8:DB:XX:XX". In any case this is checked in miflora-mqtt-daemon.py line 136...

PS: section names in config.ini also changed. See example at config.ini.dist

[sendorm]

Ok I see the problem, mine is '4C:65:A8:D4:XX:XX'. I'll try with that. I've also changed the poll rates to 180 times less for the mitemp while maintaining the miflora sleep times and also set the mqtt retain to true for homeassistant case. I wonder why the default is false.

[aqualx]

Ok, changed RegExp for MAC address. What do you mean by "changed the poll rates to 180 times less for the mitemp"? Check more frequently than miflora or ...?

[sendorm]

Yes exactly. As miflora's are for plants which don't often need an update. I use the data to auto water the plants. But with these cold days, the plants are only needed to be watered each 10 days or so. So I use a sensor refresh for 180 minutes. But with the mitemp sensors which are indoors I use a sensor refresh time of 1 minute each.

Another thing; bluepy is also needed for the mitemp.

One last thing to say, the code is working perfectly (It gets autodiscovered by homeassistant). Thank you :)

[aqualx]

But bluepy is already in requirements.txt

bluepy==1.3.0
mitemp-bt==0.0.1

[sendorm]

Yes you are right. I didn't check your tree's requirements.

[0xgrm]

Ok I see the problem, mine is '4C:65:A8:D4:XX:XX'. I'll try with that. I've also changed the poll rates to 180 times less for the mitemp while maintaining the miflora sleep times and also set the mqtt retain to true for homeassistant case. I wonder why the default is false.

Is there a possibility for the user to modify the polling rate in the config file?

[aqualx]

In config.ini there is setting:

[Daemon]
# The period between two measurements in seconds (Default: 300)
#period = 300

But for now it is used for both "Mi Flora" and "Xiaomi Mijia Bluetooth Temperature" type of devices.

[0xgrm]

I see. Maybe could you add the possibility to have 2 different polling rates for both Mi Flora and Xiaomi Mijia Bluetooth Temperature devices?

[sendorm]

You can check here for different polling rates. https://github.com/sendorm/miflora-mqtt-daemon I copied the code from @aqualx

[aqualx]

New commit:

• added separate setting "period" per device type in config.ini
• switched library for 'Mijia Bluetooth Temperature Smart Humidity' from mitemp_bt to mithermometer
• fixed schema generation for openHAB
• set 'retain=True' for mqtt messages for homeassistant-mqtt
• other minor fixes

[sendorm]

It's working, thank you @aqualx.

I am using the version by Aqualx, but after a few hours I get this error

[aqualx]

There are some exceptions from calling libraries. In last commit there is a guard against them... PS: Maybe this exceptions should be also addressed to owner. In this case mithermometer

[aqualx]

"Release unlocked lock" seems is now fixed directly in blewrap library on this change

[igorbljahhin]

I tried to use latest miflora-mqtt-daemon for reading Xiaomi Mijia, but I got "seems to be in the wrong format" error. Is the change mentioned in this thread merged into the master already or where I can find it?

OK, I found it, it is in https://github.com/aqualx/miflora-mqtt-daemon.

[Paul-B]

Which MAC address has your sensor? You have sensor with screen or without? I have two of them and both start from "4C:65:A8:DB:XX:XX". In any case this is checked in miflora-mqtt-daemon.py line 136...

PS: section names in config.ini also changed. See example at config.ini.dist

I had the same problem, my temperature sensor mitempbt is like this: Tempe1 = 58:2D:34:32:xx:xx which is not accepted and gives an error every time. As a brute force solution I commented out the mac check in miflora-mqtt-daemon.py and now it works.

[SumitBajoria]

This seems to be an epidemic. I ordered the Mijia Temperature and Humidity sensor and the MAC address is 58:2d:34:31:4b:e4. I tried commenting the mac check in miflora-mqtt-daemon.py but it did not work for me. @Paul-B can you help? What all did you comment out?

Ideally, if @ThomDietrich or @aqualx can make the necessary changes to the code so that the mac address check is either removed completely or is modified to accept 58:2D series, would be the best solution.

Thanks in advance.

[SumitBajoria]

@aqualx Will this change be sufficient or do I need to do anything else?

Init sensors from configuration files

def init_sensors(sensor_type, sensors): sensor_type_name = sensor_type_to_name(sensor_type) if sensor_type == sensor_type_miflora: config_section = sensor_type_miflora mac_regexp = "C4:7C:8D:[0-9A-F]{2}:[0-9A-F]{2}:[0-9A-F]{2}" elif sensor_type == sensor_type_mitempbt: config_section = sensor_type_mitempbt mac_regexp = "4C:65:A8:[0-9A-F]{2}:[0-9A-F]{2}:[0-9A-F]{2}" elif sensor_type == sensor_type_mitempbt: config_section = sensor_type_mitempbt mac_regexp = "58:2d:34:[0-9A-F]{2}:[0-9A-F]{2}:[0-9A-F]{2}" else: print_line('Unknown device type: {}'.format(sensor_type), error=True, sd_notify=True) sys.exit(1)

Help will be appreciated!

[SumitBajoria]

@aqualx Nothing worked so I made the following change:

def init_sensors(sensor_type, sensors):
    sensor_type_name = sensor_type_to_name(sensor_type)
    if  sensor_type == sensor_type_miflora:
        config_section = sensor_type_miflora
        mac_regexp = "C4:7C:8D:[0-9A-F]{2}:[0-9A-F]{2}:[0-9A-F]{2}"
    elif sensor_type == sensor_type_mitempbt:
        config_section = sensor_type_mitempbt
        mac_regexp = "58:28:34:[0-9A-F]{2}:[0-9A-F]{2}:[0-9A-F]{2}"

Now when I execute the script, I get the following:

pi@raspberrypi:/opt/miflora-mqtt-daemon $ python3 /opt/miflora-mqtt-daemon/miflora-mqtt-daemon.py

[SumitBajoria]

Done! I modified the miflora-mqtt-daemon.py file to include the 58:2D:34 series of MAC addresses.

The "ValueError: Publish topic cannot contain wildcards" was because I did not edit the config.ini file properly. Tweaked that and now it seems to be working. Now to get Home Assistant to use and populate the data.

[jsponz]

@SumitBajoria Could you share the code? Thanks!

[SumitBajoria]

@jsponz Which code do you want me to share? Also, I managed to fix the miflora.service, albeit, in a very crude way.

[jsponz]

@SumitBajoria you wrote: "I modified the miflora-mqtt-daemon.py ..."

Last available version of the file is 6 months old...

[CWempe]

I enhanced the regexp and created a pull request.

https://github.com/aqualx/miflora-mqtt-daemon/pull/3

[wojciej]

Hello, I just have purchased the new version of Xiaomi Temperature and humidity sensor

It is detectable over bluetooth its Mac start with A4:C1:38.

I have tried simple approach by changing the regex at aqualux fork but this does not seems to work.

If you could point me out to the right direction, or what kind of data should I provide to make this work that would be great.

Thanks you all who contribute to this great tool.

Hi Jarek,

issue is that this sensor is decrypted via a token. Binding the token to the miflora-mqtt-daemon is not supported by now.
