BMR Network Analysers
Mervis SCADA fully supports the integration of measured data from BMR network analysers using MQTT protocol.
After the installation of the analyser on site - no public IP or port forwarding is needed to communicate all data to Mervis SCADA. The communication is fully encrypted.
Supported Devices
Device Configuration for Mervis
Configuration is performed in the standard BMR PMS configuration tool. On the “MQTT” tab, set the following connection parameters:
- Enable MQTT protocol permission
- Server: mqtt.mervis.info
- Port: 8883, also check Use TLS for this option
- Mervis also allows an unencrypted connection on port 1883. In this case, TLS must be unchecked. However, we do not recommend this option.
- Other parameters (User, Password, ID, and UID) will be provided after registering the device in Mervis.
