#I have two philips hue lights (https://

I feel it's worth mentioning that I had both of these lights connected and working under ZHA with the same zigbee dongle for a years time. I am migrating away from ZHA to Z2M (I have made sure to properly uninstall ZHA)
I have tried rebooting HAOS as well as just restarting z2m from the web ui.

That stick is petty crap and hasn't been recommended for years
marsh quail
Yep
Just hoping it would work because it's worked for me so far
And the fact that I managed to get one of the lights connected for a bit

That said, if it's on a USB extension cable and you're clear of wifi then it should work - up until a dozen or so devices

Yeah I'm only attempting to use two lights and a trådfri dimmer
The trådfri dimmer connects without any problems

Could be that they're not resetting correctly

But yeah I'm just gonna have to get a new dongle as soon as I get my next paycheck

The Z2M doc pages that you linked describe a way to pair the bulbs using the IKEA remote, did you try that?
marsh quail
Yep, the bulbs didn’t go into pairing mode at all using that

And also did you try having the bulbs closer to the coordinator (HA/Pi)?

The other light I have is <50cm from the zigbee dongle
And my apartment is only 25sqm so no matter what there’s line of sight from the dongle to both the lights
The weird thing to me is still just how one of the bulbs connected but now won’t connect again

Too close? Meh - it shouldn't be this hard.
As you only have 3 devices, you could quickly try different Zigbee channels too : 11, 15, 20, or 25 are often recommended as the most reliable

Oh, and the CC2531 has a low limit on how many devices can talk directly to it
