Integratie DSMR-logger met Home Assistant

(met dank aan Bas van de Lustgraaf)

De data uit de DSMR-logger kan op verschillende manieren met Home Assistant gedeeld worden. Verreweg het makkelijkste is dat door gebruik te maken van een MQTT Broker.
De DSMR-logger publiceert de gegevens uit de Slimme Meter in een bepaald topic. Home Assistant moet dan een subscription op dat zelfde topic hebben om zo de gegevens in te lezen en te presenteren.

Vaak draait Home Assistant thuis op een server (Raspberry Pi of anderszins) en is het eenvoudig om op die server ook een (Mosquitto) MQTT broker te installeren (veel installaties van Home Assistant hebben dat al standaard gedaan).

Om de intergratie voor elkaar te krijgen moet in het configuratie.yaml bestand van Home Assistant onder andere deze instellingen komen te staan:

group:  !include_dir_merge_named groups/
script: !include scripts.yaml
sensor: !include_dir_merge_list sensors/
switch: !include_dir_merge_list switches/
light:  !include_dir_merge_list lights/
camera: !include_dir_merge_list cameras/

mqtt:
  broker: <ip-adres-MQTT-broker>
  port: 1883
  client_id: HassIO
  keepalive: 60
  username: <user name>
  password: <password>

Hierdoor zal Home Assistant alle (yaml) bestanden die in de sub-map groups/ staan inlezen. Hetzelfde geldt voor de sub-mappen sensors/, switches/, lights/ en cameras/.

Voor de koppeling met de DSMR-logger zijn alleen de sub-mappen groups/ en sensors/ van belang en natuurlijk de settings voor de MQTT broker!

In de sub-map groups/ komt een bestand DSMR-Actueel.yaml met de volgende inhoud:

###group: ###
###VIEWS###

Energie:
  name: Energie
  entities:
    - group.Energie_Verbruik
    - group.Energie_Teruglevering
    - group.DSMR_Last_Update
    - group.Energy_Graph1
    - group.LastUpdate

###CARDS###
DSMR_Last_Update:
  name: DSMR Last Update
  entities:
    - sensor.DSMR_Last_Update

Energie_Verbruik:
  name: Energie Verbruik (actueel)
  entities:
    - sensor.Energy_Delivered_T1
    - sensor.Energy_Delivered_T2
    - sensor.Power_Delivered
    - sensor.Power_Delivered_l1
    - sensor.Power_Delivered_l2
    - sensor.Power_Delivered_l3
    - sensor.Gas_Delivered

Energie_Teruglevering:
  name: Energie Teruglevering (actueel)
  entities:
    - sensor.Energy_Returned_T1
    - sensor.Energy_Returned_T2
    - sensor.Power_Returned
    - sensor.Power_Returned_l3

Energy_Graph1:
  name: Energy Graph 1
  entities:
    - history.energyGraph1

en in de sub-map sensors/ komt een bestand DSMR-Actueel.yaml met deze inhoud:
