I have two IKEA tradfri buttons that are linked to HA via ZHA. These buttons originally paired just fine and since few days back, they stopped worked. I tried to remove and get them to re-linking/pairing mode (pressing the pair button 5 times within 4/5 second) but they seem to be completely dead and doesnโt wanna go into pairing mode (no red light).
Has anyone had any experience on getting this to work again? I replaced the batteries as well but no signs at all.
Replace the batteries, fiddle with the buttons randomly until it re-pairs (i.e. (+) Add New Device). Yes, this may take a while. Remove the batteries for a few hours, and try again.
Add a mains powered Zigbee device(s) to act as a router (ZR) - e.g. a TRADFRI control outlet. Mains powered radios can shout louder, and help move from point-to-point to mesh topology.
Add any Zigbee device(s) to increase the amount of mesh coverage. More devices help move the topology from point-to-point to mesh.
