Z2M can'f find new TuYa devices

Configuration Zigbee
1

Dear HA friends,

My problem:
Since yesterday I am trying to pair this TuYa plug with Z2M without success. Logs dont even show an attempt to interview.

What I have tried so far:

  • I have 5 of these plugs and tested with all of them. Z2M wont find any of them when in pairing mode.
  • I paired and unpaired on IKEA air quality monitor and it worked without flaws.
  • I worked through the Zigbee FAQ on pairing issues (incl. Z2M restart and re-flashing coordinator)
  • Pairing through one of the routers in my network istead of the coordinator.

My hardware:

My Z2M config.yaml:

Did you restart Zigbee2MQTT ?

As part of the Zigbee FAQ I restarted Z2M including disconnecting the coordinator for 10 seconds before restarting Z2M.

Do the Zigbee2MQTT logs show something ?

Logs show that new devices can join, however, interview never starts. Example below:

after the “allowing new devices to join” message no interview is initiated

Are you sure the plugs are in pairing mode?

Is “Steckdose Schreibtisch neu” the name of your Tuya plug?

Yes, absolutely sure. The plugs go to pairing automatically when you plug them in and they have not been paired before. Also tried it with 3 different tuya plugs. none of them shows up in the devices list of Z2M.

It is the name of one of the tuya plugs. I have 4 up and running:

Wait, what am I missing? If you can see them in the device page, it means they paired correctly.

If you’re talking about the 5th missing plug, try to force it into pairing mode by following the instructions in the Z2MQTT page (or the link in my previous post)

Wow, it hardly can get any more random…Today, just out of curiosity, I tried pairing a 4th and 5th TuYa plug (same make and brand) and they were able to pair. I thought I am going nuts and tried the other 3 devices which I was talking about earlier: all 3 of them cant pair. For now my hypothesis is that all 3 of them are from a bad batch. Cant explain it otherwise.

thanks @francisp and @ShadowFist for your replies!

Sure, it was about adding an additional plug. And yes, I forced it into pairing mode many times. However, seems to be solved now.
