Connecting AirPoint - M (metering) to WebHMI
This version of the AirPoint module is intended for reading data from heat meters via the M-bus protocol and transmitting telemetry data via the MQTT protocol to data collection systems.
Features
- Compatible meters: DIEHL Scylar INT, Siemens FUE950, Danfoss Infocal, and their equivalents
- Connection using a standard connector (included with the module) instead of the communication board of the heat meter
- Energy saving polling cycle
Connection method
M-bus protocol
All meters are read with “REQ-UD2” request using broadcast address. The M-bus tags are mapped onto statndard AirPoint's MQTT topics:
Value | Description | Units | Mapped to |
---|---|---|---|
FWT | Forward temp. | °C | “temp_int” |
RET | Return temp. | °C | “temp_ext” |
E | Energy | Gcal | “counter_in1” |
VOL | Volume temp. | m3 | “counter_in2” |
Q | Forward temp. | °C | “hum_int” |
