Support for reading power production and consumption values and counters from the AURUM Meetstekker web-page.

Place the files __init__.py and manifest.json in the custom_components/aurum directory and add the following to the configuration.yaml file (example):

aurum2mqtt:
   device: 192.168.0.110                  # ip adress of the meetstekker
   broker: 192.168.0.111                  # ip adress of the MQTT broker
   username: mqtt_user                    # MQTT username
   password: mqtt_password                # MQTT broker password
   select: [6,7,8,15,16,17,18,19,20,22]   # optional, example
   client: MQTT client-id                 # optional, default is 'aurum2mqtt'
   scan_interval: 20                      # reporting interval, optional, default 60 seconds (note: the Dutch Smart Meter refreshes every 10 seoconds)

There are in total 23 sensors available:

- E net consumption        #power-flow of the electrical connection connected to the DSMR meter with p1-port
  unit_of_measurement: "W"
- E low in totals          #total Electricity consumption - low tariff
  unit_of_measurement: "kWh"

  unit_of_measurement: "kWh"
- Gas rate                 #gas-flow, works only with an analog gas meter, needs a special add on
  unit_of_measurement: "m3/hr"
- Gas totals               #total gas consumption
  unit_of_measurement: "m3"

Not all sensort might be active. Look at http://'ip-address-of-the-Aurum-unit'/measurements/output.xml to find out which sensors show actual values. Then modify the numbers in the config-line select: [6,7,...] to match your installation.

The selected sensors are automatically detected by Home Assistant via MQTT discovery.

Please note: the MQTT messages are transmitted with the retain-function active. This makes these sensors compatible with the home Assistant Utility Meter: https://www.home-assistant.io/components/utility_meter/
