Monitored by the Portal
All IoT-Portal diallers are cloud-monitored. Every 4 minutes the portal checks in; if it can’t reach the dialler, the unit reboots automatically. If it remains offline for over an hour, email and optional SMS alerts are sent to administrators.
Firmware updates are applied automatically — keep it powered and we keep it running.
