The ZED-TIDCI-M is a battery powered ZigBee device, capable to count pulses emitted from flow rate meters (water, gas, electricity,...) and to measure the temperature from both the 2 on board NTC inputs.

The ZR-TIDCI-OPT1-EM is part of the ZB-Connection family. It counts, stores and transmits to a Gateway of the ZBConnection 4-noks family optical pulses generated by a counter ENEL, which correspond to a certain energy measured by the latter.
