Here is some details on the chip:

Any news?

i found that this sensor communicates using uart. But tuya component can’t read any datapoint

4

this shit really needs to be an ISO standard. Im over the amount of devices bought that are now just door stops.

Minor update:
If I connect the uart directly to the new esp8266
esp8266 will have tasmota
So the console in tasmote according to the instructions:

I guess:

Cmnd 2: Pir
Cmnd 6: Battery
Cmnd 8: Tamper

is there any possibility to capture it in the home assistant?
Or read uart in esphome?

I have no experience with tasmota. This is my first flashing.
