So I’ve tried everything. My two Nanoleaf devices have been unavailable for the last few days. I’ve restarted the app, restarted my Homey (Pro - latest). Nothing!

They’re available through the Nanoleaf app (so definitely online) but Homey can’t see them.

Anyone got any ideas?

Does it show any error message on the unavailable screen? Maybe session is expired and you need to log in on Homey again?

I have a number of Nanoleaf devices (WiFi and Thread… 4D TV backlight, pole floor lamps, B22 bulbs etc) and I am running a Homey Pro (2026) on the latest firmware. I don’t have any problems recently. But a while back I had a problem with the 4D TV backlight not joining my Thread network properly, which caused some connection problems for my Thread devices.

Can you provide more details of the models of Nanoleaf devices you’re having problems with, and perhaps some screenshots showing the errors, to help diagnose the problem? Restarted and nothing doesn’t give us a lot to go off.

This is about the regular Nanoleaf devices though, as @Casper181TFG mentions that they are still showing as Online in the Nanoleaf mobile app, while Thread devices can’t use the mobile app. So this must be about a WiFi device.

So my Thread devices showing and being controllable in the mobile app is an anomally then? 🤭🤭🤭
