Linking DSMR wireless to home assistant

Hardware

Hi There,

Im looking for a solution to connect my DSMR (dutch smart meter) to my home asistant, since i do not have any wiring i can use i need a wireless solution.

I do have a spare Pi3 or some ESP32 boards available that i could use but no idea where to start. any ideas would be greatly appreciated.

What version did you install? Did you configure mqtt host, credentials and topic?

I have topic DSMR-WS

Part of my sensors in HA:

_ sensors.yaml included in configuration.yaml (sensor: !include sensors.yaml)_

- platform: mqtt
  name: P1 Actual Power Consumption
  unit_of_measurement: 'W'
  state_topic: "DSMR-WS/JSON/power_delivered"
  value_template: "{{ (value_json.power_delivered[0].value | float * 1000.0) | round(1) }}"

- platform: mqtt
  name: P1 Actual Power Consumption L1
  unit_of_measurement: 'W'
  state_topic: "DSMR-WS/JSON/power_delivered_l1"
  value_template: "{{ (value_json.power_delivered_l1[0].value | float * 1000.0) | round(1) }}"

- platform: mqtt
  name: P1 Actual Power Consumption L2
  unit_of_measurement: 'W'
  state_topic: "DSMR-WS/JSON/power_delivered_l2"
  value_template: "{{ (value_json.power_delivered_l2[0].value | float * 1000.0) | round(1) }}"

- platform: mqtt
  name: P1 Actual Power Consumption L3
  unit_of_measurement: 'W'
  state_topic: "DSMR-WS/JSON/power_delivered_l3"
  value_template: "{{ (value_json.power_delivered_l3[0].value | float * 1000.0) | round(1) }}"

Do you see messages on mqtt?

Try listening to DSMR-WS/# via the listening option on Configuration >> Integrations >> MQTT >> Configuration to see if something is reported.

Every few seconds there should be some new messages.
