Does anyone have any experience with Govee water/leak sensors (Amazon)? And integrating these into Home Assistant?
I naively purchased these on sale late last year before diving into Home Assistant, in earnest. The sensors work well, and the app has been… functional. I have no big complaints. However, since it does not integrate in Home Assistant, the functionality is greatly limited for me. All of my research on these, after the fact, has been unfruitful.
Does any method exist to integrate these? MQTT, HACS, Tasmota, RF receiver?
The gateway appears to be model H5040, and it utilizes 433.92 MHz to communicate to the sensors. In the FCC internal photos the components are not clear enough to determine if an ESP chip is used. I can try to tear down my own if it looks promising for flashing tasmota. There are clear GND, Rx, Tx, and 3V pins.
While I would much prefer local polling, I’ll take what I can get. On the HACS front, I noted in the current android app release notes (V3.5.0) there is a new option to request for API key:
I did this, and promptly received an API key via email, along with an API reference document. Unfortunately I am not a developer and cannot easily utilize this. It does appear to use JSON formatting and one with experience could probably easily implement this with HACS. Weirdly, the H5040 isn’t listed as a device compatible. I don’t own any other Govee products but maybe this will help someone else.
I greatly appreciate any and all help from the community.
