[Release] Virtual Gas & Water Meters — Cumulative meters for Homey Energy

Hi everyone! :waving_hand:

I’ve built a small app that adds virtual cumulative meters for Gas and Water so you can track them in Homey Energy with history and use them in Flows.

What it does

  • Adds two device types:

    • Virtual Gas Meter (meter_gas, m³)

    • Virtual Water Meter (meter_water, m³)

  • Works as cumulative measuring devices → shows up in the Energy tab (Gas/Water).

  • Comes with Flow actions to set, increase, and reset the counters.

Why?

Many of us have readings from an external meter (utility bill, smart valve, manual readings…) and just need a simple way to keep a running total in Homey, see trends in Energy, and automate updates via Flows.

How to install

Add a device

Devices → + → Virtual Gas & Water Meters → choose Virtual Gas Meter or Virtual Water Meter → Add.

Make it show up in Energy

Energy needs at least a couple of samples to draw deltas:

  1. Open the device Settings and ensure Exclude from Energy is off (if available on your build).

  2. Trigger a few small increments with short delays (e.g. +0.05 m³ two or three times).

  3. In Energy → Gas/Water, switch the timescale (e.g. Last 24 hours) to refresh.

  4. In case that there is still no data after few hours, try to reset App

These counters are cumulative – values should generally increase over time. A manual reset is supported but will impact charts.

Flow cards (examples)

  • Set gas meter to… → set an absolute reading (e.g. from your monthly bill)

  • Increase gas meter by… → add a delta (e.g. daily/weekly usage)

  • Reset gas meter → set back to 0 (use with care)
    (Same trio exists for Water.)

Known notes

  • The “Tracks total home energy consumption” toggle typically applies to electricity; for Gas/Water you’ll mainly see Exclude from Energy (depending on your Homey version/UI).

  • If Energy shows “No data available”, send a couple of increments and change the timescale; the panel usually populates immediately after new samples arrive.
