AmbiPower – Giving Power Back in The Hands of The Utilities


Ambimat’s AmbiPower is an Automatic Meter reader which communicates with a Utility meter (Water/Gas/Energy) and a Head End System over a cellular network. The modem is capable to independently sending commands over DLMS (RS232) to the meter. The AmbiPower uses a proprietary Edge computing algorithm that can parse the meter data locally on the device itself. This feature helps utilities to bring down the data usage i.e. running cost paid to cellular networks as well as increases the reliability of meter communication. The modem can also sending specific SMS based on some pre-defined events detected from the meter. This provides greater flexibility to use the modem for not just data monitoring but also remote surveillance of tampering activities.

AMR Features:


  • Meter connectivity over IEC62056(2011):DLMS/COSEM
