I’ve got an IKEA hub connected to a few Trådfri lights which I’ve then added to Home Assistant on a Raspberry Pi and set up a load of automations. I moved the hub and the RPi around my room and now Home Assistant can’t control any of the lights, it’s just reporting Failed setup, will retry. The IKEA hub can still control the lights fine.
Any idea if there’s a quick fix or do I need to bite the bullet, delete the config and set everything up again from scratch?
Like others said, most likely your HA IP changed, had this happen recently in a power outage. Need to either set them to use hostname or make the HA machine have a static IP.
