CGH1 Sensor in Home Assistant. Cannot see them

Compatible devices
1

Hi, i’m Laurent.

i’m using OpenMQTTGateway 0.9.8 with HomeAssistant.
I would like to see with you how to declare a CGH1 sensor in OpenMQTTGateway into my Home Assistant Platform.
i try to remove battery from sensor and starts it again. no change in Home Assistant
i try to open and close my window, no change in Home Assistant
Where can i find some logs files ?

in MQTT Explorer we can see this

{
“id”: “58:2D:34:60:xy:zt”,
“name”: “Qingping Door/Window Sensor”,
“rssi”: -80,
“servicedata”: “3058d603c24a1860342d5808”
}
but cannot understand where open/close information is

Thanks for your support
Laurent

Hi Laurent,

Can you download the QingPing mobile app and add the sensor, disconnect the Bluetooth of your mobile and check if you see different data in MQTT explorer.

Hi Florian,

i added all my sensors through the Xiaomi Home application when i installed them in Home Assistant. All have been recognized thourgh BLE Monitor add on.

i used them into Home Assistant through BLE monitor and i have correct status from them.

When all are closed i have the following :

i disable bluetooth on my phone.

After a restart, i got this in MQTT Explorer

same behavior.

in your ZgatewayBT.ino file, in process_cgh1 function, i don’t undersand “0804”, “8804” etc… values. these values are not present in my Servicedata values

Thanks for you support.

Laurent.

This may be due to the provisioning of the sensor through the Xiaomi app instead of Qingping app.

Could you try to remove it from Xiaomi app and add it into the Qingping one.
When provisioning the sensor it is configured to a particular format. The Xiaomi one is encrypted but not the Qingping one.

Did auto discovery work for you in home assistant? If so we the created entries the right device class? Mine are showing up as generic sensors so they don’t display in a meaningful way out if the box in home assistant.
