I suspect that the bulbs perhaps do something non-spec-compliant
I suspect this too, but I believe there may be more going on.
So, yesterday I factory reset everything the 2-1 switch and the 4 bulbs, re-paired through the blue switch (connect through device via home assistant), recreated the group for the 4 lights I’m controlling, and re-bound the switch to the group. After several hours, 3 of the 4 bulbs showed up under the switch as children with 200+ LQI. The 4th bulb never joined. After another couple hours, the 3 bulbs that were children of the switch dropped, and connected other devices in my network (the coordinator and/or a tubes zb router) with much lower LQIs (around 40). The lights mostly were still controllable through the switch, though the colors/brightness weren’t always the same from bulb to bulb. I was careful not to issue too many commands within close proximity, and disabled all automations associated with that zigbee group.
I also have a hue motion sensor right next to the blue series switch (hue). It too prefers choosing a route through other devices much further away (LQI of about 50 when not connected to the switch, LQI of 200+ when connected to the switch). I’ve been checking on the children of the switch periodically to see what’s going on, and the list is different about every time I look at it.
I also added a new Sonoff zigbee 3.0 plus dongle flashed with router firmware between the switch and the coordinator just to see what would happen… The switch itself still responds to every command I’ve sent it.
@EricM_Inovelli, if you need ANYTHING that might help get to the bottom of this issue, please let me know. I’m comfortable capturing events, logs, and whatever else you want. I’m pretty familiar with the debugging process for embedded devices, though in other domains.
Thanks!
Edit:
Would removing the switch from the network and seeing what happens help at all?
I’ll add other info I think might be helpful here:
The dimmer has a connection to the coordinator with a LQI of 171.
I discovered that a newer version of the coordinator/router software is available for my sonoff router/coordinator (20220928). Giving that a shot now.
