I have a feature request for following water timer: RainPoint
This is a Tuya device, so because of their appalling API is unlikely to be included as a core integration.
You can get a limited amount of control like this: Tuya Irrigation Hardware (Rain Point) - Problems with Integration - #15 by fotidim
I have seen the topic already. Is the work around supporting the external sensor?
No only control of the valve.
Is the sensor in the Tuya app available?
I would assume so but as I don’t have the device I don’t know for sure.
You can integrate it with one of the Tuya custom components available in HACS
