Hi there!

I have some cheap BLE Xiaomi Mijia Mi Temperature and Humidity Monitor 2 (LYWSD03MMC), with Telink custom firmware installed ([Telink Flasher](https://atc1441.github.io/TelinkFlasher.html)) and integrated in Home Assistant. They show in real time temperature and humidity, as well as the battery state.

When I add them to Homey through the Home Assistant app, I can easily detect all the “entities” (except battery state, don’t know why), but when added I cannot read the measurements.

There is a way to read them correctly in Homey?  
Thank you in advance!! 👋🏻

Guys, I have just put together an application that scans for these devices flashed with ATC firmware.  
The code is quite dirty, feel free to use or modify it. 🙂  
Already submitted as an application to Homey.

Hello ZsR, I paired my temperature sensors with your app. Flashed ATC, everything paired good but on senzor, there is 27°C, in Homey 1°C. Any idea what can be wrong?

Thank you

Hi,

I tried install the app to Homey, but I get error:  
✓ Pre-processing app…  
✓ Validating app…  
× Homey App did not validate against level `debug`:  
[  
{  
“keyword”: “additionalProperties”,  
“dataPath”: “.images”,  
“schemaPath”: “#/definitions/images/additionalProperties”,  
“params”: {  
“additionalProperty”: “xlarge”  
},  
“message”: “should NOT have additional properties”  
}  
]

What could be the problem? Thanks!
