60 Blue Series switches all on Firmware v2.10
Sonoff P-Series (TI chipset) Zigbee 3.0 Dongle
Home Assistant + Z2M, both latest stable releases
Multiple 4-way switch and 3-way switch scenario’s.
… and not a single issue with Zigbee Binding. Have yet to have it fail even once.
The only issues noticeable:
-Dimming speeds are intermittently different and use one setting or another instead of doing what they should as I mentioned previously.
Now onto Hubitat…
I’ve setup the same exact environment as above except for with a C7 Hubitat Hub. Constant disconnections, constant Zigbee bindings failing.
I have no idea why, I was using both single and group binding on both Hubitat and Z2M.
It seems the more devices that route through an individual switch, the worse that switch routing performance and overall performance becomes, so I’m not sure if making the routing table larger will fix the problem with binding, I would think it would make it worse with the current z stack.
As for network flooding, on v2.10 I don’t see too much of it. Although, I have a few of the power reporting settings disabled in the firmware. The switches still do report wattage power when the switches are on every few seconds, but that doesn’t seem to cause any problems.
I think we are starting to see that some coordinators just can’t handle too many devices, and I believe some of the manufacturer’s just don’t want to admit it. For example, I used a Conbee II with Home Assistant and Z2M in the beginning and had terrible performance as well with the switches, but after switching to the Sonoff P (Texas Instruments chipset), everything is stable. I hope this helps someone, because this made a giant difference between wanting to rip my hair out vs having a functioning stable setup, and not having to worry about “will the switch work this time?”.
Do you guys allow testers? I have a smaller test setup of 15 switches where I’m modifying the EEPROM manually via direct board communication. If there is a better way to make changes and test just let me know.
