Battery-powered device support

[pavel211]

Hi!

Can your program work with battery-powered devices, such as a door opening sensor?

For example, this: https://templates.blakadder.com/TY01.html

I bought several such sensors with CB3S controllers, but it is impossible to link them locally with the standard firmware, no TUYA-MQTT converters work, the device simply does not have time to respond to the request and turns off.

Hi, I have just bought some previously ESP8266 equipped window/door sensors and they also got switched for a new generation by now.

Looks like more and more devices are being exchanged by now which makes it more interesting to have battery powered device support built into the OpenBeken firmware.

This device in particular uses a CB3S chip which hosts a BK7231N and bluetooth capabilities.
I was able to flash the firmware through the pins on the module as a test and get a reed sensor status update through the tuyaMCU driver on channel 2.

I don't know enough about the tuyaMCU driver or how to extend it's implementation to do it myself, but I could try to have a look once I find some time on my hands.
Any hints where to start? Can I just cross compare the implementation with Tasmota and remap pins or something?

bump because Tuya integration in HA is really crappy right now and the device is flashable, but lacks software support for deepsleep etc.

for door sensors, I use the MI BLE version, 2032 lasts about a year.
I use TAS on ESP32 to listen to the BLE adverts....

I have a set of Tuya sensors with CBU chips:

and I've logged their uptime reports from (using the Tuya developers portal):

That's with the standard firmware of course, and if reflashed we'd want comparable performance for battery conservation.
