Optimizing Home Assistant Performance on Raspberry Pi

As a long-time user of Home Assistant, I’ve always been impressed by its versatility and the endless possibilities it offers for automating my smart home. However, I’ve recently encountered an issue that I’d like to share and discuss with the community.

I’m running Home Assistant on a Raspberry Pi 4 with a Conbee II stick. For the most part, it’s been fantastic—sensors and bulbs respond with zero lag. But after a week or so, I’ve noticed that the system starts to slow down. Devices respond slower and slower until the whole setup just stops responding altogether. I can’t even reach the HA interface on port 8123 or my HADashboard. Restarting HA gives it a temporary boost for a couple of days, but then it just hangs again.

I’m currently considering running a cron job to reboot the system every few days while I investigate further. But I’d really appreciate some guidance on where to start looking. Are there specific logs or diagnostics I should review? Has anyone else experienced similar performance degradation over time?

In the meantime, I’ve found that keeping the system updated and monitoring resource usage helps mitigate the issue to some extent. I’d love to hear if others have tips or tricks for optimizing Home Assistant performance on a Raspberry Pi setup.

Thanks in advance for your insights and suggestions!
