Energy clarity, without the noise.
See exactly where your energy is going: solar, battery, grid, and house, updating in real time as it happens. Self-hosted, so it stays your data, on your own hardware.
See your energy at a glance
No accounts you didn't ask for, no subscriptions. Just useful software.
Live energy flow
Watch power move between solar, battery, grid, and house as it happens, pushed to the display over a live connection rather than polled on a page refresh.
Shows what you have
The display is built from the sections your hardware actually reports. No battery configured? No battery section. Nothing to hide or configure around.
Self-hosted & private
Run it on your own hardware with Docker Compose and PostgreSQL. metrd reads from your inverter and services; your data stays on infrastructure you control.
Solar forecasting
See predicted generation for the hours and days ahead, alongside what your panels are producing right now.
Sensible history
Readings are kept at full resolution while they're recent, then bucketed down over time, so history stays useful without storing every point forever.
Built for light hardware
Designed to run comfortably on modest hardware rather than a beefy server, with every request and database round trip treated as a cost worth avoiding.
Integrations
metrd reads from your hardware and a couple of outside services. It never sends anything back, it just listens. Here's what talks to it today.
Inverters & Batteries
- SolaX LocalSupported
- SolaX CloudSupported
- GivEnergyPlanned
- More brandsPlanned
Forecasting
- SolcastSupported
Tariffs & Pricing
- Octopus EnergyPlanned
This list is short because metrd is young, not because we're precious about hardware support. Take a look at the roadmap for what's coming, or the integrations docs for how each one works.
Energy monitoring shouldn't be complicated
Most energy apps are cluttered, subscription-heavy, or locked to specific hardware. metrd is a small, focused tool that does one thing well: shows you where your energy is going, right now.
It reads from your inverter and a couple of external services, it doesn't send commands back. No charge schedules, no tariff slots, no remote control. A window into your system, not a way to change it.
It's being built in the open, on hardware you probably already have, because more people should be able to see where their power actually goes.
- SimpleSet it up once, then open it and see your energy. That's the whole idea.
- HonestNo subscriptions, no upsells, no accounts you didn't ask for. Free and self-hosted from day one.
- YoursSelf-host it on your own hardware, modify it, keep your own data. It's your software.
- CalmDesigned to inform, not alarm. No gamification, no guilt trips about your usage.
- Earlymetrd is alpha software. Expect rough edges, missing pieces, and things that change.
What we're working on
A rough plan, not a promise. Priorities shift as we learn what people actually want to monitor.
Working on now
- Live energy display: solar, battery, grid, and house, updating in real time
- SolaX inverter and battery support, over your local network or SolaX Cloud
- Solcast solar generation forecasting
- Self-hosted Docker Compose stack: API, App, and PostgreSQL
Up next
- GivEnergy inverter and battery support
- More inverter and battery brands, using the same adapter pattern
- Octopus Energy tariffs, so cost and value show up alongside the numbers
- EV charger support, as another device on the display
- Alerts for offline devices, a stuck battery, or a sharp forecast change
- A historical trends view, and multi-user accounts
Up and running with Docker Compose
No accounts to create or forms to fill in. Just a database, an API, and an app, running on your own machine.
Start the stack
Clone the repository and bring up the full stack with Docker Compose.
git clone https://github.com/ernokieran/metrd.io.git
cd metrd.io
docker compose up -dConnect your hardware
Add your inverter, battery, or forecasting service. See the integrations docs for what's supported and what each one needs.
Open the dashboard
Visit localhost:3000 and you're done. Mount a tablet on the wall if you fancy, the display is built to be readable from across the room.
Want to help?
metrd is alpha and rough around the edges. If you're interested in better energy visibility for your own home, we'd love your help testing it, building it, or just sharing ideas.
