I have got hold of four zigbee coordinators to assess. In the short term I have been running a Conbee II but it has been dropping out once or twice a day and then doesn’t come back up reliably (I’ve recently changed to the /dev/serial/by-id/… mapping which may be more reliable).
I now have:
- Tubes ZB CC2652p2 USB/Ethernet
- Zigstar CC2652p2 POE/Ethernet
- Sonoff gen 3.0 dongle plus
- Conbee II
This is on a rpi4 with everything in Docker containers. The SSD is plugged into a USB2.0 port to lower the interference. The USB dongles are on extender cables. The ethernet capable coordinators can be located anywhere on my house network, powered by POE. The rpi4 is also on POE right now. I’ve also got some Echo devices with zigbee, so there will be some zigbee interference from them (no idea which channel).
I have two buildings networked over fibre and an IOT VLAN with just one instance of HA planned for now. I probably have a preference now for the ethernet solutions but stability will trump everything.
I’ve got all four stood up in different zigbee2mqtt containers issuing different base topics and sitting on each of the 11,15,20,25 zigbee channels. I’ve done a single device migration test pairing it onto a different coordinator and managed to get it to appear in Home Assistant and then dropping it out and pairing it back to the original. (it was a bit more of a struggle than I’d hoped. After interview on the new coordinator it would drop off the new network. I had to block it on the old network to make sure it went across)
My thinking was to migrate just one repeater and one device to each of the networks and leave it running for a bit to assess stability. Not really a stress test. The Conbee II benefits from having a few repeaters already on its network so it won’t be fair until I move some repeaters over.
So I can rig this up and get some LQI measurements and then maybe swap channels as a double check for Echo zigbee interference. I can’t really stress test the coordinators until I mass migrate the network.
Is there anything other test that makes sense?
Am I missing a trick for dropping zigbee devices off one network and them playing nicely on the new one straight away?
