ZBT-2 with 7.4.4.6 firmware just barely works. Web Toolbox has a weird issue

Configuration Zigbee
1

Guys, I have a new ZBT-2. It installed and connects, but it barely works. It connects to 1 or two endpoints or routers on my zigbee network. Advice is that the factory-installed firmware, 7.4.4.6, has issues, downgrade to 7.4.4.5. Ok, I used Web Toolbox to do that. Update proceeded without error. However, the ZBT-t after update, reports STILL running 7.4.4.6! I’m stumped. Checked and did this twice. Same result. Performance is still very poor. Key debug log entry:

UPDATE: Interestingly, the ZBT-2 does not appear in the z2m devices list.

This is normal. Coordinators aren’t shown in the Z2M device list, so at least that’s 1 less thing you have to worry about.

Can’t help with the rest of your issue, sorry.
