Which guide fits my project?

For the first commissioning of the M-Center, start with the step-by-step guide. If meter data should go to Home Assistant, Loxone, Node-RED, ioBroker or Grafana, the integration guides show the way via Modbus TCP or MQTT. The blog and the glossary explain the background of M-Bus, Modbus, MQTT and LoRaWAN.
