Hi,
I have bought zigbee stuff from ikea and paired to zha using zigstar lan gateway, but the ikea stuff stops working lately, i guess when zigbee gateway disconnects from zha, as it does for whatever reason.
Is there a way to avoid these issues other then throw it out and not use zigbee stuff anymore?
I was plagued with this issue. Was stuck re-connecting my zigbee devices to my Sonoff Zigbee 3.0 USB Dongle Plus every day or two. In the end I replaced all my Ikea batteries with new ones and I have not had any issues in almost 2 months now. I definitely recommend replacing the batteries that are supplied with the Ikea devices to see if that helps. My zigbee network is not very large as I wanted to test out a few components before expanding it. (2x TRADFRI on/off switch, 1x TRADFRI 5 button remote control, 1x TRADFRI bulb E26 CWS 800lm)
I tried batteries before (varta, panasonic, duracell, energizer) it keeps disconnecting.
I thing I will give up on wireless buttons until there is some on bthome or the like, this just just too much not working stuff for my OCD.
