Usage Scenario
Server Room Tracking and Relay Control
NetRelay in server rooms; It monitors the temperature inside the cabin, turns on the fans, and triggers alarm relays and notifications when the internet or critical host goes down. With Ping Watchdog, you can monitor network health of up to 4 IPs.
- • Automatic fan/air conditioner relay on temperature threshold
- • Monitoring up to 4 hosts with Ping Watchdog
- • Local alarm on internet outage (not cloud dependent)
- • NOC / Zabbix / Home Assistant panels with MQTT integration
Cabin alarm scenario
It opens the fan relay when the cabin temperature exceeds the threshold; If the threshold continues for a long time, an external siren or SMS gateway can be triggered with the second relay. Local control continues uninterrupted when the internet is interrupted.
Why is local control critical?
Cloud-based IoT gateways remain blind to network outage. NetRelay acts as a local network automation device within the LAN; external access is not required.
