Hello! I’m fairly new to HA, and have been trying (i.e bashing head against a wall) to integrate an Ikea Tradfri E1810 button into my HA setup via a Sonoff Bridge running Tasmota without success. My end goal is to control a particular Lifex bulb that is also integrated into HA.
The button is connected to the Sonoff Bridge
(I did have a screenshot, but am limited to one image as a new user)
The button press actions are being picked up by the bridge, and broadcast on the network as an MQTT message, which HA is able to see
I’ve tried SetOption19 1 and then restarting HA - no success
I then tried SetOption19 0, restarted HA - no success
From what I understand, Tasmota should automatically add the button as a device in HA - is this correct, or should I not expect to see it here?
(I had intended to insert a screenshot of the Tasmota integration card displaying “1 device, 9 entities”)
If I shouldn’t expect to see the button in the tasmota integration, do I need to attempt MQTT discovery?
I’m not keen on setting up zigbee2mqtt as the docker deployment looks pretty fiddly and HA can almost see the button anyway.
How do I get HA to recognise the button so I can then use it to turn a light on and off?
Thank you!
Please assume I’ve read the docs and ELI5
