From the reading to the bill
Helvatron makes the meters. For data acquisition and analysis, we recommend two products from our sister company EMU Electronic AG in Baar, which are tailored to Helvatron meters.
The data path
Which device does what?
Our experience in the Gulf
Why we recommend the EMU M-Center
M-Bus and Modbus, MQTT with the Helvatron MQTT broker as a service, built-in SIM and BMS interfaces: in the Gulf region, we read more than 300,000 meters this way.
