evcc now supports the ADA P1 Meter

We are pleased to announce that the ADA P1 Meter has been officially added to evcc's supported meters – meaning evcc can now directly use the ADA P1 Meter's real-time measurement data (via LAN/HTTP).

This is an important milestone: evcc can truly make “smart” decisions based on accurate measurement data – for example, optimizing EV charging based on solar surplus or dynamic tariffs.

What is evcc, and why do so many love it?

The evcc (Electric Vehicle Charge Controller) is an open-source, local energy management system specifically designed to optimize electric vehicle charging. The essence: charge your car with as much self-produced energy (e.g., from solar panels) as possible, and only draw from the grid when it truly makes sense.

What makes it truly good:

Runs locally (e.g., Raspberry Pi / NAS / Docker), not “cloud-dependent”.
Supports many wallboxes, inverters, batteries, vehicles, and meters.
It views the house’s energy flow “as a whole”: PV production, consumption, grid, battery — and makes decisions based on that.

What does the ADA P1 Meter integration add?

evcc needs good data for “good decisions.” The ADA P1 Meter provides exactly that: real-time import/export power and energy data from the meter, which evcc now handles as an official meter template.

This is great because now evcc can, for example:

see exactly how much power is going in/out of the grid,
more finely charge from PV surplus,
more stably regulate performance (less unnecessary switching on/off).

In short: how does the evcc ecosystem work?

evcc reads and controls from several “points”:

Meters: measurement points (grid / PV / battery / others)
Chargers: chargers / wallboxes that it controls
Vehicles: if online interface is available, extra smart functions (limit, schedule, minimum charge, etc.)

The ADA P1 Meter is now an official “meter” within this system.
