First of all, yes, I’ve tried another power supply and new SD-card. This Pi has been running Hassbian stable for at least a year and before that it ran as a Kodi box. It has been extensively stress tested with this PSU without issues. Recently upgraded from a Hassbian install to Hass.io and that’s when the problems started.
I’m running the latest version of HA (0.100.3).
The issue I’m experiencing is that the Pi becomes completely unreachable once or twice every 24h. Front-end down obviously, not reachable by SSH and it’s off the network (can’t ping the IP). On reboot everything seems normal, but logs are cleared so I have no idea what’s causing this.
How would I go about trying to troubleshooting this? Is it possible to enable persistent logs somehow?
