Problem solved !!!

Hello, everybody,
after many readings I managed to integrate YIERYi yy-w9909

this is the link: https://it.aliexpress.com/item/1005008093991319.html?spm=a2g0o.refund_spm.0.0.555e36528w1ct4&gatewayAdapt=glo2ita

even though it came to me with a broken display, it works on the Smartlife APP, and you can integrate it into HomeAssistant with Local Tuya.

Attention LOCAL TUYA and not TUYA LOCAL there are two integrations on HACS.

In any case, first follow the step-by-step directions from this video !

Leaving a note here to whoever comes here after me.

My device is PH-218 WiFi smart online 8 in 1 tester.

After some trial and error, I manage to set it up with TUYA LOCAL integration.
The official HA Tuya integration only gave me the current temperature.
The LOCAL TUYA integration gave me error: Connection to device succeeded but no datapoints found, please try again. Create a new issue and include debug logs if problem persists. I was even toying with the idea of direct api call to tuya iot platform.

Then I tried TUYA LOCAL (GitHub - make-all/tuya-local: Local support for Tuya devices in Home Assistant). Added immediately with all sensor available.

Hope this helps someone

The more I read about the localTyua solution the nervous I got, what a hassle…

Maybe a bit late (or not) did someone used the EspHome CB3S recent integration with this unit?

It could make things easy to install (only 1 time hardwired programming needed) and really easy OTA…

-edit-
Can get my hands on the device next week, my yaml (starting whit these lines) does compile without errors!
Correct functioning needs to be confirmed…

esphome:
  name: ph_w218

bk72xx:
  board: cb3s

ESPHome is functioning perfectly (now)!

If only I had known earlier, that HA - Discovered - “Add” was essential; this is the key to obtaining the reply value 4 for “TuyaMCU network status” requests.

Without this, no data is exchanged between TuyaMCU and CB3S.
