I have a V2 hub and had no problems until we had a power cut of a few hours. Once power resumed, all my Ikea bulbs have gone offline.
I’ve tried rebooting the hub and none have come back. I’ve left them on for days to see if they’d somehow reconnect, but nothing.
So, I resorted to trying to add device for Ikea bulbs. Walking through the process, I get to the point where it tells me to power the bulbs off and on 6 times, to start them pairing, and they bulbs should acknowledge this state with some flashing, which they do, but that stage in the pairing never advances and eventually the bulbs time out and revert back to static brightness.
I’ve tried this with the Ikea GU10 (TRADFRI bulb GU10 WS 400lm) and Ikea E27 (TRADFRI bulb E27 W opal 1000lm), both the existing in-place ones and brand new out the box. Same result for all… the bulb pulses and waits, the app never advances and eventually times out saying ‘There was a problem connecting to the device. Try again.’ Err code: 34-302
I see all of these were reporting a ZigBee route that has a middle hop of ‘↔ Unknown Route (???) ↔’, which may be one of my battery powered zigbee thermometers, that died during that long power outage.
Edit: I’ve just noticed that a few of my old Belkin Wemo bulbs are also offline, so tried to pair them just using the App to Scan for devices, while the bulbs were blinking. Nothing. The Scan process times out with nothing found, again.
Edit2: I noticed my Ikea ZigBee motion sensors were also now offline, so tried to pair those the normal way. The device goes into pairing mode and red led slowly blinks, but the pairing process never detects them.
I’m at a loss for ideas and even more perplexed that a long power outage has caused such disruption of a previously stable environment, and more so now that it seems I can no longer re-pair or even add devices.
