@hellomiakoda but you used to. Back when they had CRTs in them.

When's the last time anyone actually dialed a phone?

@plaetzchen a couple of things that can help:

Check the mesh map and see what signal strength you're seeing for the devices.

If you made a topological change in the past couple of days, sit tight. It may just shake out and then be stable. I had to learn patience with Zigbee.

@briankrebs I had to look this up. It's ridiculous how they present it on the packaging!

@plaetzchen I went through this. The problem is that #zigbee unavailable status is a symptom, like having a fever. And, like a fever, it shows up with so many underlying causes that it can be nearly impossible to diagnose without other symptoms.

For example, when I add or remove repeater devices, the mesh gets unstable for a few days and I sometimes have to wake devices up or re-pair them during that time. And then they get stable and everything is ok.

I had another issue where a large number of database writes was slowing down the #raspberrypi 4 #homeassistant server enough to cause the Zigbee controller to go offline and reset, causing all devices to go offline for a couple of minutes.

And all of this was after I carefully chose my channel and the channels I use for my wifi APs to minimize interference.
