Getting analogue water meter readings into EnergyID

I still have an analogue water meter and was tired of entering the readings manually into EnergyID every month.

I've been using EnergyID for a while now and it's a great way to track our energy consumption. Thanks to an integration with our digital meters, I can get the gas and electricity readings into EnergyID automatically. But since I still have an analogue water meter, I need to enter the readings manually.

I've bought a second-hand Homewizard water meter to be able to send the meter readings to my Home Assistant instance.

Getting the meter in Home Assistant is easy as it is detected automatically.

I ran into a problem here because the total consumption was somehow stuck on another value than the actual consumption. Resetting the meter did not help.

Using a Helper (Settings > Helpers > Create Helper > Template > Template a sensor) I was able to create a helper that fixes that by adding a number until the total consumption was correct.

Webhook permalink

Inside EnergyID I activated the Incoming Webhook app and created a new webhook.

I then created a new rest command in Home Assistant to send the data to EnergyID.

I had to use {{ utcnow() }} to get the current date and time in the correct format as the timezone needs to be included. The payload data comes from the templated sensor. The remoteId is a unique id you can choose yourself.

rest_command:
  EnergyID:
    url: https://hooks.energyid.eu/services/WebhookIn/xxx/xxxx
    method: POST
    content_type: 'application/json'
    payload: '{"remoteId": "Drinkwater","remoteName": "Drinkwater (webhook)","metric": "drinkingWaterImport","metricKind": "total","unit": "m³","data": [["{{ utcnow() }}", {{ states.sensor.meterstand_water.state }}]]}'

I then added an automation to trigger this rest command every day at 00:00.

- id: '1738772892634'
  alias: Send water meter reading to EnergyID
  description: Triggered at 00:00 every day.
  triggers:
    - trigger: time
      at: 00:00:00
  conditions: []
  actions:
    - action: rest_command.EnergyID
      metadata: {}
      data: {}
  mode: single

The water meter readings now appear automatically in EnergyID. I saved a whopping 2 minutes every month!
