Best way for reboot condition on Sensor Loss

[bottkars]

Hello all,


i a still running on iConnect, and recently added a WM300.
However, i am still facing some Sensor disconnects where the USB Connected WMR is no longer reachable.
A reboot always solves the Problem.

most of the time we can find events like datalog: Wetterdatenaufzeichnung seit mehr als 30 Minuten ohne neue Daten

Is there a way to force the system to do a reboot if Datalogger no longer receives Updates ?

I could cron into the eventlogs to do so, but i am looking more for a if condition x then do y in the Meteohub system ....

i created a watchdog script for this that runs in my environment
an email is sent via msmtp using muttclient,
and the server is automatically restarted.
that also eliminates the need for my nightly reboots
( fo mail,, i added a set from="meteohub@maildom" reflecting the settings from the mailconfig in meteohub in root#s .muttrc,
and copied the .msmtprc from meteohub )
and

Code: Select all

meteohub:~# more check_usb.sh 
   #!/bin/bash
    #
    # watchdog servive to onitor the loss of usb connetion to wmr on meteohub
    #
    # Runs as a cron job to keep an eye on ringbuffer entries for USBDEVFS 
    #
    # This needs to be run as root or a user that can monitor system services.
