ZigBee temperature and humidity ZED-THI-M Sensor

The ZED-THI-M drill is a ZigBee battery supplied device which can measure at the same time the temperature and humidity and regularly send the collected information toward one of the gateways of the 4-noks range.
Is possible to set the device in order to manage alarms to ring when its limits are trespassed, because of an exceeding value or of a too small value. It is also possible to schedule the sampling timing and the sending modalities of the measurements in order to increase the duration of the battery.
