I’m struggling to get my new ZBT-2 communicating to a Zigbee device, and need some troubleshooting tips to help me narrow down whether it’s a problem with the ZBT-2 or the Zigbee device, a frient Electricity Meter Interface 2.
How can I determine if the ZBT-2 is working okay? Should it display any lights during startup, or during the “add device” operation? Is there a way to determine if the ZBT-2 is actually transmitting? Is there some hidden button I need to press to by the ZBT-2 into pairing mode?
I added the ZBT-2 as a Zigbee device, selected “Recommended Installation”, and it installed okay and two integrations appear:
Home Assistant Connect ZBT-2
Zigbee Home Automation
I’ve put the ZBT-2 on a longer USB cable to get it away from my PI5 and also from my Z-Wave dongle.
Just trying to work out where my problem lies - with the ZBT-2, or the frient Electricity Meter Interface 2.
EDIT: Log from attempted pairing:
