In the link below I have explained an issue that I am experiencing again. I have taken a clean SD card installed Hassio and put it in my Pi 3b. After a few weeks, the automations stop working and the bot doesn’t send any messages anymore. First thing I have done is to check if the Pi which is connected by an ethernet cable and has a fixed IP is visible in the router, and it is not.
I connected a screen to see if anything is visible, screen stays black, there is no output signal,
I have pinged its IP, time out.
I feel I have to do a clean install again but I do not want this to happen again, is there anything obvious I am missing? Don’t want to be in the same place every 2-3 months.
