My Zigbee devices have been very unstable (mostly IKEA Tradfri devices), i get many timeouts, rejoin network, grouping works 50% of the time, etc. etc. It works, but its far far from stable. Now im running v4.2 still. I changed the tradfri devices to get connected to a hue bridge today, and let Homey add them afterwards through the Hue app. It is still very unstable, also the hue app seems to have troubles.
Anyone having thoughts? Or are the IKEA devices just trash? My few hue bulbs (through hue brdige and homey) seem to be working very stable.
