The AmbiAutomation HVAC Bridge Board talks BACnet or MODBUS to building automation equipment such as chillers, VRVs and VAVs, and reports the building network vitals for preventive maintenance. Ethernet, RS485/RS232 and out-of-the-box cellular connectivity.

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.
