Hi,
in the interest of finding a better thermometer to act as inout for a thermostat, I got a Shelly H&T G3.
First thing: Its “Action Button” is a reset button hidden behind the battery door, which you cannot reach when the USB C power supply is plugged in.
The Shelly integration worked fine for a Shelly Pro EM3, so I assumed other Shelly devices should be fine as well.
I followed the instructions for setting up a Gen3 Shelly from https://www.home-assistant.io/integrations/shelly/ and it was quite the ordeal to get the right websocket URL in. Its also not clear to me what setting I should use for the “TLS connection” since I run home assistant without TLS at home currently – all the instructions I can find are about the web based config which I cannot access, and the Shelly App is always giving me “the device is asleep and will be updated when it wakes up the next time”, even if powered via USB; and hitting the action button sometimes puts the device in setup mode, sometimes doesn’t, but the settings dont take.
In the shelly app, the H&T reports as the Websocket being active, but the device does not pop up in auto discovery, nor can I add it via its IP address …
Am I missing something, or is this expected with the more recent Shelly firmwares?
I am running HAOS on x86 with
