This document defines the properties of Micropelt’s maintenance free, indoor room temperature sensor with Set Point functionality and Presence Detection MLRTPS.
...
MLRTPS is an 868MHz LoRaWAN CLASS-A wireless actuatorwallmount thermostat. LoRaWAN allows to control over long distances, even inside buildings. LoRaWAN end-devices of Class A allow for bidirectional communications whereby each end-device’s uplink transmission is followed by two short downlink receive windows. The transmission slot scheduled by the end-device is based on its own communication needs with a small variation based on a random time basis (ALOHA-type of protocol). Class-A operation is the lowest power end-device system for applications that only require downlink communication from the server shortly after the end-device has sent an uplink transmission.
...
To operate the device, the unit must be paired with a compatible controller or gateway unit supporting its communication profile. Once After connecting the battery and mounted on the wall and activated using the magnetic key, the device attempts to connect to a gateway. If the connection to the gateway is successful, then it is ready for use.

The MLRTPS has a built-in temperature sensor to measure the ambient temperature of the room. A Passive Infrared Sensor (PIR) is used to detect motion in the room to and reduce unnecessary heating when there is no one present. The MLRTPS also has a temperature set point functionality. The rotary dial is used to select the required Set Point Temperature. The Set Point may be absolute or relative depending on the model of the MLRTPS.
