Hi Andreas,
to change RMS monitoring just send an SMS message to the router‘s SIM card number with the rule's SMS Text. This rules are: “Switch monitoring on/off” and “Monitoring status”. If Authorization method is “By router admin password”, sms text will be:
admin01 monitoringon – to enable RMS connection
admin01 monitoringoff – to disable RMS connection
admin01 monitoring_status – to check RMS connection status
Note: <<admin01>> is default RUT password and should be replaced by your admin password.
