The modul needs 12V DC power supply. It can switch 2 independent relays by LoRa downlink message.
How does it work:
the modul sends a keepalive signal in every 1-60 minutes to the gateway (user configurable value). If any command needs to send to the module, it will be sent to the relay module in the confirmation (downlink).
Please consider this latency of the LoRa communication when you are planning to use this relay. This relay can be used typically for slower processes, when no immediately response required.
Possible applications:
– water sprinkler
– outdoor lights
– heating/cooling (to enable/disable but not as regulator)

This kind of relay is not recommended to use for gate control because the user typically wants to open the gate immediately without any delay.

Operation modes:
– monostable (the ON time is adjustable)
– bistable
– monostable reverse operation (N.C., opening time is adjustable)
– alternate mode (for shutters)
