Hi, Mikael, I've added the simple toggles at the top of the script to control remediation actions. The script will always notify, but the restart weewx and reboot host actions are completely optional and controlled simply by the variables at the top of the script.
If both restart weewx and reboot host actions are enabled, these become nested in that first the restart weewx will be tried one time and if after watchdogsecs the station is still not reporting, then the host reboot will occur. You can enable one or the other or both. I also added logic to check if the host was rebooted within 2x watchdog secs to avoid reboot loops. I strongly recommend not lowering the watchdogsecs below 600 (10 minutes). It's important to note that my approach isn't actually checking whether the weewx process is running, rather, the loss of communications checking is based on whether weewx has written any records to the database lately. You'll find the update over here: https://github.com/UberEclectic/weewx/tree/watchdog/examples/watchdog BTW, if you use my script don't run another kind of weewx restarter script, or they will step on each other. (Or at least be sure to disable the weewx restart toggle in mine).
