Is there a script for a rig offline telegram notification that Im missing? The telegram messages are awesome, but would be good to know if it powers down and stay down.
If system is going to be rebooted you will get notified from script that send the reboot command (watchdog or temp control), but if your rig freeze there is nothing to do.
You can set up an external watchdog like an RPi to check your rigs ping and ssh port and send you message if they were unreachable.
