Conbee3 random sensors don't come back after each power loss/power flash

I kept having random sensors lost at odd times. Finally, I was at home yesterday for a power loss. I just noticed that 7 of my 63 sensors were offline. Per Phoscon and Home Assistant data they all lost power roughly 26 hours ago which is when the power flashed. This requires me to delete those devices and re-add them in the Phoscon add-on for Home Assistant each time. This is getting quite annoying and cumbersome.

Of note, I have 3 wall outlet switches (similar to wemos) and 1 hardwired light switch that are connected to the Conbee. They can and do appear to act as hubs in the deCONZ add-on app diagram.

I am running the latest firmware from July 2024 - deCONZ_ConBeeIII_0x26530900.bin.GCF.

A similar post went unanswered last year - Power Loss problem

Can anything be done to improve stability after power recovery of devices?

How many routers do you have?

3

I have 3x eero 6 pros acting as APs.

4

I mean zigbee routers.

Sure, so I have 5 devices acting as such currently. I will have 3 more smart plugs when I add Christmas switches in a couple weeks.

1x - Enbrighten Zigbee Dimmer Amazon.com

2x - Innr Zigbee Smart Plug Amazon.com

2x (increasing to 5x) - THIRDREALITY ZigBee Smart Plug Amazon.com

I think this is your issue.

In general you would like to have 5 sensors per router / end device

So add more routers?

And Xiaomi/Aqara sensors leave the network if they can’t reach their parent after a time.

@Smanar sure so the power flash is pretty much instant on/off/on and so it would take a few seconds for the zigbee routers to reconnect to the conbee3 which is on a UPS and remains online.

@mimiix I now have 8 zigbee routers in use.

Ha ? so you have lost sensors with just a few seconds power cycle ?

13

That is correct. Instant power flash causes several aqara devices, entirely at random, to lose connectivity and require a full reset (delete/re-add).

Strange, it’s “lazy” device, they are not able to see a router fast power cycle …
