I have same issue. Nowhere can the scanned sensors be seen inside HA. So kind of makes no sense to even add Tasmota intergration for this Tasmota32 BLE device.
I also tried manually adding MQTT sensor but I get tons of errors in log since the MQTT topic (tele/tasmota32_ble/SENSOR) is same for all sensors and using device specific MQTT path will break when json attribute if not found:
tele/tasmota32_ble/SENSOR = {"Time":"2021-08-20T13:30:29","ESP32":{"Temperature":71.1},"TempUnit":"C"}
Template variable error: 'dict object' has no attribute 'ATCxxxxxx' when rendering '{{value_json['ATCxxxxxx'].Temperature }}
I am sure you get this errors in your log too.
You still have MQTT auto discovery option which works great. Just set this under console:
SetOption19 1
I am using it currently. Only thing that is not working like I wish it would, is that all the sensor values are unavailable when I restart home assistant and they stay like that until ESP32 scans them again and Tasmota passes the values to MQTT. Would be nice to get last read value when HA restarts.
Any other idea what I can try?
