# [Release] Virtual Gas & Water Meters — Cumulative meters for Homey Energy
Hi everyone! 👋
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:
- 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
- **App Store:** [Virtual Gas & Water Meters | Homey](https://homey.app/a/com.horak.virtual.meters/test/)
## 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.
## Feedback
Bugs, ideas, questions? Please reply here with:
- Homey model & firmware version
- App version
- What you tried (e.g., Flow steps)
Thanks for trying it out! 🙏

Hello Martin, just installed your app, build a flow to give input (via push message with question) and that works fine! Just… I entered a decimal and I can’t figure out if you app is able to register decimals. This is for water a wish.
I don’t have gas but oil. I measure it in liters and enter for example 518 liters as 0.518
Here I miss a third decimal. So a second wish 🙂
I wil further try the app the next months. Thnx! This helps a lot

I have been playing with [GitHub - jomjol/AI-on-the-edge-device: Easy to use device for connecting "old" measuring units (water, power, gas, ...) to the digital world · GitHub](https://github.com/jomjol/AI-on-the-edge-device) to read values of a hidden meter. I haven’t finished a working setup yet, but together with the virtual meters app, this might be a great combination. Not sure how they should fit together exactly, but having meter readings from another input into Homey Energy would be great!
