An open, hackable energy manager built on the Matter protocol — reading consumption, generation and tariffs from real hardware, and bringing it all together on a single pane of glass. This is the running log of how it’s being built, piece by piece.
Commercial energy systems tend to be closed boxes — your inverter talks to its app, your meter talks to your supplier, and nothing talks to each other. The goal of this project is the opposite: one manager, speaking the open Matter standard, that pulls together everything happening on the wires in my house. Consumption from the grid, generation from solar, the live price of electricity — all in one place, all under my control.
Getting there means working up and down the stack: ESP32 firmware, Modbus and Matter plumbing in the middle, and a phone app to tie it together at the top. The posts below are grouped by where they sit in that picture. If you’re new here, start with the milestone post, then follow whichever thread interests you.
The Manager itself
The brain of the system — onboarding devices and proving the recording loop works.
Connecting energy sources
Prices & demand-side response
Knowing what energy costs right now is what makes the system smart, not just informed.
The groundwork
An always-on, wired manager needs solid networking foundations underneath it.
This project grew out of earlier Matter experiments. If you want the back-story, the Matter Heating Monitor series is where a lot of these techniques were first cut by myself.
