Python Script or plugin for Xiaomi Mi Temp and Humidity Sensor

[Auflauf]

Hi Everybody,

i have four Xiaomi Mi Temperature and Humidity Sensors (lLYWSDCGQ/01ZM https://www.aliexpress.com/i/32849595532.html) and i'm searching for a way to integrate them into domoticz. I found a library with examplescript to poll them directly from the raspi without gateway (https://zsiti.eu/xiaomi-mijia-hygrother ... pberry-pi/). Is there a way to parse the output directly into domoticz as sensor?

thanx for any help in advance
Regards

Here you can find a script and a manual for use with Domoticz.
https://github.com/pFenners/mijia-sensor-domoticz

Use

Code: Select all

sudo hcitool lescan

to find the sensor and note the MAC address of the device.

After downloading the code from GitHub, you must make 3 changes to the file

domoticz_mijia.py

At the first line type:

Code: Select all

#! /usr/bin/python3

And line 25 you must change the word:

Code: Select all

base64.encodestring

into

Code: Select all

base64.encodebytes

At the end of the script there are 3 examples of the function update.
Eg.

Code: Select all

update("58:2D:34:39:18:66","120")

Remove the # of one of the functions and replace the MAC address with the one you noted.
The number after the comma, "120" is the IDX of the sensor in Domoticz.
To test it you can now run the command:

Code: Select all

./domoticz_mijia.py

Where do i find this file? It's not in the repository...

[Mike70]

Sorry.
I used the wrong github address.
You should use this one: https://github.com/pFenners/mijia-sensor-domoticz

Minor detail...

First upgrade to Buster this weekend, then I'll look into it.

Thanks!

how does this work? using a esp32 of some kind with bluetooth? i could not find which device to use for bluetooth connection. i do not want to use the bluetooth on my pi since it does not cover the whole house. with multiple esp32 it would be possible but it is not listed how to do that.

[Mike70]

I noticed that 1 Rpi does not receive all the units in our house. You could use an ESP32 on each floor.
I have a Rpi on each floor. That is a choice you can make.
For use with an ESP32, see this video: https://www.youtube.com/watch?v=RtJpx8BZvMw

I adjusted the script as per instructions.
When I run the script I get:

Traceback (most recent call last):
File "./domoticz_mijia.py", line 5, in <module>
from mijia.mijia_poller import MijiaPoller, \
ModuleNotFoundError: No module named 'mijia'

I also installed the script mija_poller, made it executable and added python3 to it.
Any ideas?

Hi All, could anyone solve tis?
I am also stuck after following the instructions above:

Traceback (most recent call last):
File "domoticz_mijia.py", line 5, in <module>
from mijia.mijia_poller import MijiaPoller, \
ModuleNotFoundError: No module named 'mijia'


Any help?

Perhaps easier to use a Python plugin like viewtopic.php?f=65&t=22281

In case some of you are interested, here the solution for the Mijia V2 (

I am getting sometimes an error "Failed to connect to peripheral", but it works from time to time and I can see the data in my domoticz

[Menno]

Hey, thanks for that!
Getting somewhat further now.
Just like you I get the occasional "Failed to connect", but also " Bluetooth command failed (code: 1, error: Invalid handle)".
And when it is working, I don't see the "INFO The request is http://192.168.178.23:8080/json.htm?typ ... battery=74" line in my log file.
No data appearing in Domoticz.
When I use curl to post the data myself, I see it appear in Domoticz, so the error seems to be on the side of the script, not on the Domoticz side.

menno@quokka:~$ curl 'http://192.168.178.23:8080/json.htm?typ ... battery=74'
{
"status" : "OK",
"title" : "Update Device"
}

That's for the Flower Mate, I don't think it works for these devices.
I also own a Flower Mate and the scripts works for it, but does not pick up my three Xiaomi Temperature and Humidity Sensors.
Meanwhile, back to getting the module not found error.

For Python module load errors check the last paragraph of the wiki https://www.domoticz.com/wiki/Using_Python_plugins

Hi Menno,

Can I ask you to come over to the thread of the Temp & Hum Sensor 2, and give me some hints to move forward making it working for me, please?
For me the script is not even getting to this part, only prints the following lines:

Code: Select all

2023-08-06 17:20:02 INFO     ***************************************

I'd appreciate your, or anyone's help.

I started to play with the script, and eventually changing the scanner.scan first param from 10 to 15 made it work:

Code: Select all

try:
        scanner = Scanner().withDelegate(TempHumDelegate())
        scanner.scan(15.0, passive=True)
except Exception as e:
        logger.error(str(e))
        pass

I have 2 sensors to scan and read their data.

Nothing there at that link, but did you get it working?

[Menno]

The script no longer works.
I get 401 errors, despite having allowed basic-auth and having the proper IP-ranges as trusted networks.
Anyone else experiencing this and more importantly, having it fixed?

[Havym]

Yup, i'm also having troubles..... also with this plugin... viewtopic.php?t=34348
