I'm using HAOS, and the subset of devices relevant to BTHome stuff is:
(I can provide more details if folks think it's relevant, but those are the only new devices + the only BLU/BTHome ones, and 3 of them are working.)
Everything on HAOS is fully up to date, and all the devices have been upgraded to the latest firmware.
I set up the gateway, and as soon as I pushed the buttons on the BLU Door/Window and BLU RC Button 4, Home Assistant prompted me to add them to the BTHome integration.
I can't get it to ask me about the BLU H&T, though, for some reason.
I have confirmed that the Shelly integration logs have this line, and a lot of similar ones, all mentioning the 7c:c6:b6:23:01:82 MAC address I confirmed belongs to the device:
{
"seq": 841,
"ts": 1751165221.76,
"level": 2,
"data": "shelly_notification:210 Event from script:1: {\"component\":\"script:1\",\"id\":1,\"event\":\"ble.scan_result\",\"data\":[2,[[\"7c:c6:b6:23:01:82\",-76,\"AgEGDxbS/EQAnQFjLjk6AUUzAQ==\",\"\"]]],\"ts\":1751165221.72}",
"fd": 1
},
So this means, as far as I can tell, the Shelly integration gets this information, but doesn't prompt me to add the device.
I can't figure out how to add a BTHome device manually, either. If I go to the BTHome integration, and click "Add Entry" it says No devices found on the network.
