Wrong forum, I know, but not completely.
My Tradfri remote needs a new battery. The last time I swapped the battery, nothing worked, including HA commands to the Tradfri. I wound up resetting everything to “factory” and reinstalled and re-linked the lights, remotes and gateway. Following this I had to reconfigure the Gateway in Home Assistant.
I would like to just change the battery in the remote. Is my experience an anomaly? What’s your experience?
