4. Functionality
The NV-R718T2 functions as a wireless interface for dry contact inputs, allowing users to monitor the state of external devices such as door sensors, mechanical switches, or relay outputs. Each of the two input channels can independently detect open or closed states. When a contact state changes, the device can immediately transmit an uplink message to the LoRaWAN network server, ensuring near real-time status updates.
The device can also be configured to send periodic status reports at defined intervals, even if no state change occurs, providing continuous monitoring capability. Configuration parameters such as reporting interval, input type (NO/NC), and transmission settings can be adjusted via downlink commands through the LoRaWAN network.
Typical Use Cases:
- Door/window open/close monitoring
- Equipment status detection (e.g., relay ON/OFF)
- Alarm system integration
- Push-button event detection
- Industrial process monitoring
- Smart building automation
- Remote switch monitoring in utility or infrastructure systems
Compatibility:
- Compatible with any LoRaWAN-compliant gateway and network server (e.g., The Things Network, ChirpStack, Loriot, Actility).
- Integrates easily with IoT platforms and cloud-based monitoring dashboards via standard LoRaWAN data payloads.
