New Watermeter

Configuration

Hi there,

I got a new water meter installed yesterday. Before I had a counter with normal numbers and analogue pointers.
Now I got a digital counter, which I can continue to read with “al on the Edge”.

Since the counter starts at 0.000 and my old counter stopped at 1086, I am wondering how I can continue at the value 1086 so that there are no discrepancies in the Energy Dashboard.

My “Al on the Edge” device is integrated via MQTT:

   - name: "Water meter consumption"
     state_topic: "water meter/meter reading/value"
     unit_of_measurement: "m³"
     state_class: "total_increasing"
     device_class: "water"

I thought I could do this with a value template:

   - name: "Water meter consumption test"
     state_topic: "water meter/meter reading/value"
     unit_of_measurement: "m³"
     state_class: "total_increasing"
     device_class: "water"
     value_template: "{{ states('sensor.watermeter_consumption_test') | float + 1086 }}"

Unfortunately that doesn’t work.

Does anyone have an idea - or what is the best way to proceed?

Thanks very much
greeting
Herbert

Maybe you can to this in:
Developer tools > Services > Utility Meter: Calibrate

So you pick your water meter and manually put the value, you want to start from.

Maybe it is the way.
