Alarm messages
Alarm messages can be send as SMS, by e-mail or MQTT (you have to choose one of the drivers).
To use e-mail or MQTT you have to enable/configure the corresponding driver, see
chapter “Email or
MQTT output”. But if you don’t want to use the driver to transmit the “Log data” as well, its recommended
to schedule the driver to transmit just the “Actual Values” once a day to avoid unnecessary
communication payload and according power consumption.
System Alarm
Check this option if you want to send system alarms messages (like Deployment start, sensor timeouts
(sensor could be broken), or TCP/FTP/HTTP server not available, etc.)
Data Alarm
Check this option if you want to send data alarms messages (e.g. when a measurement is outside its
defined limits).
