Ikea Stoftmoln lamp: unreliable zigbee connection

Morning everyone, quick question into the round: anyone else who is struggling with unreliable zigbee connections of the Ikea Stoftmoln ceiling lamp? I’ve got the big one for a few days now, connected to a physical power switch for the general on/off when walking into the room. The problem: most of the times it’s reliably detected by HA/ZHA as available, but there is a continuous occurance of me switching on the lamp, but it not showing up in HA as available. I then need to switch it off and on again, and then it shows up in HA. The lamp is 2-3 meters away from my conbee2 stick, so I would want to rule out range issues.

Any hints? Highly appreciated :slight_smile: Cheers!

There’s plenty of very detailed Zigbee troubleshooting posts in the forum if you search, but the key question is does the device switch when you need it to?

I’ve seen battery devices sleep to save energy and show as unavailable due to a timeout, BUT work fine when an event occurs. This is a mains-powered device so it should be a mesh router, but you never know.

It never hurts to add another cheap IKEA mains switch nearby as they do work as effective mesh routers (ideal to reduce battery drain on remotes).

Well, the baseline functionality (light on/off) is provided by the physical wall switch, so that one is covered :wink:
It’s just really annoying that in order to then set a different brightness, you sometimes need to walk back to the wall switch for a “reboot” first.

About adding another repeater: the distance between conbee stick and lamp is super close, to add another repeater inbetween would mean to have it dangle from the ceiling between the 2 :wink:

Mesh radio never propagates the way you think - I speak from experience. Try another mains powered device nearby.

I am very new to smart Zigbee devices. I was thinking that smart lamps like that are not supossed to be switched of via the traditional switch but only via Zigbee and so stay powered all the time. No?

For me that’s just part of my “fallback philosopy”. When our HA instance breaks, we still can do the basic stuff “by hand”. I wouldnt want to live in a setup, where the most essential stuff isn’t available otherwise.
