It adds a separate sensor for every field in the MQTT topics which is named `sensor_dsmr_`. ## Prerequisites To use this DSMR Reader sensor integration, you need to have a DSMR Reader instance running and an MQTT broker to send sensor data through. 1. Add the MQTT broker integration in Home Assistant, if you haven't done so already 2. Configure the MQTT broker in the DSMR Reader application 3. Enable the following data sources in the DSMR Reader administration pages with the default mappings: - Day consumption: Split topic - Gas consumption: Split topic - Meter Statistics: Split topic - Quarter-hour peak consumption: Split topic - Telegram: Split topic {% include integrations/config_flow.md %} ## Difference with the DSMR integration This integration relies on the presence of an existing DSMR Reader application setup. It processes the events triggered by the MQTT publishing feature to create sensor entities within Home Assistant. This integration uses the data published on the MQTT broker, no matter how or where the application is installed. By comparison, the [DSMR](/integrations/dsmr/) integration adds a full instance of the DSMR Reader application within Home Assistant. It is possible to have both integrations installed at the same time and working together, but this is not required.
