I have a dedicated ZigBee router that has dropped off from my network a few times now at around 4:15am. Any ideas why this might be happening? It’s plug into a standard USB power plug.
Any automations or housekeeping happening around that time?
Is your time zone about 4 hours away from GMT?
Is your power stable?
Any clues in your system logs?
Copilot research is suggesting it could be due to high CPU usage triggered by database purging that happens around that time. This particular router has dropped off two or three times at around the same time so I’m thinking it could be related. I’m using HA via a Windows 11 laptop running a VMware virtual machine. I know database purging can be pretty CPU intensive and possibly more so because I’m retaining 30 days data and the database is around 3.5gb. I’m going to cut it back to a smaller period and see if that helps
This is around the time HA pushes the backup and cleans the database by default…

You may be running out of resources. Memory, disk space, tasks, etc. Any crashes showing in your VM logs, Windoze logs, HomeAssistant system logs?
Is your laptop going into sleep mode about that time?
Ok so it could be a CPU or resources issue. A few end devices have recently dropped off and whilst i haven’t traced the exact times, I have been loading up HA with Esphome updates, compile and install activities which see my CPU go to 100% from the use base of around 30%. Very annoying. I need to dig a bit deeper. Maybe it’s even interference generated at higher loads.
