They keep becoming unavailable. I did a lot of troubleshooting on them. Some of it discussed here.
- Removed all incompatible repeaters from the network.
- Turned my WiFi APs down to the lowest required power.
- Assigned the APs to channels that don’t conflict with the zigbee channels my hubs run on.
- None of the zigbee hubs (hue, smarthtings, huzbusb) share channels.
