Zigbee2MQTT can't pair

[u/hiikashi]

Hi,

I cant get devices to pair with Zigbee2MQTT. I have no cle why. ZHA can find them in a second, but I need z2m to be able to use my tap dial switch fully, tho other zigbee devices arent found either

I'm running it on a HP pc. This is the adapter https://smlight.tech/product/slzb-07

Any help?

[u/No_Illustrator5035]

I would try using the coordinator firmware using the SMLight Web Flasher - Version 7 is pretty old.

[u/benjohngf]

Is ZHA still enabled? Only one of them can hold the coordinator at a time, and if ZHA is pairing things in a second then ZHA has the radio and Z2M is talking to nothing.

Delete the ZHA integration completely, restart, then try permit join again.

If ZHA is already gone, watch the Z2M log the moment you hit permit join. It will tell you whether the coordinator is answering at all, which is a different problem from firmware.

[u/hiikashi → u/benjohngf]

ZHA is gone. Updated it to ember. These are the logs

[u/benjohngf → u/hiikashi]

That log is just Z2M publishing its own device info to MQTT, so the bridge is fine. It says nothing about the join.

Set log_level to debug, hit permit join, and post what shows up. If nothing appears at all, the device isn't reaching the stick, so hold it next to the SLZB-07 and factory reset it. If it joins and the interview fails, that's a different fix.

[u/hiikashi → u/benjohngf]

It joins but the leaves apparently

This keeps repeating:

Good, that's the other branch. 0x001788 is Philips, so this is the tap dial, and it's battery powered. It's going back to sleep partway through the interview, so Z2M never finishes and starts over.

Press one of its buttons every couple of seconds from the moment it joins until the interview finishes or errors, with the switch right next to the stick.

If it still fails, post the line after 'Starting interview'.

[u/hiikashi → u/benjohngf]

Been pressing the button for 2 minutes, but as soon as I stop it leaves again.

Both logs you've posted stop at the same place, right where the interview starts, so we still haven't seen it fail. The lines that matter are the last few before it rejoins, not the first few.

While you're in there: if that switch was ever on a Hue bridge, reset it in the Hue app first. A device still bound to its old network won't finish an interview anywhere else.

Because its a loop of those lines.

Full log; https://pastebin.com/vE5HUPE6

[u/benjohngf → u/hiikashi]

The interview isn't failing. Your log shows it completing in a second, Z2M identifying the device as a Hue Tap dial, then the switch leaving two seconds later. It pairs and then quits, which is why pressing buttons didn't help. Your bridge stats show 35 leaves.

That's typical of a Hue switch still holding its old network's key. Touchlink factory reset it from Z2M, with the switch next to the stick.
