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?
Check what IP HA is expecting and then check the IKEA hub to see if they match. If you have DHCP turned on for your hub then when you moved it it might have gotten a new IP. Easy fix its the case, just set a static IP on the IKEA hub for what HA expects and then restart the integration.
Or make it old school and use the hostname instead of the IP.
