evcc-io: open-source EV charge controller and home energy manager (Germany). Skoor 50, n=4, confidence 0.8

Data problem: the hiring signal, weighted 20 of the 50 points, comes from evcc.com, not evcc.io [source]. The sampled roles are emergency veterinary jobs in Michigan and Indiana [source]. Inference: this is a different organization, and the Skoor is overstated by 20 points.

What they built

evcc is an extensible EV charge controller and home energy management system [source]. Its stated goal is local energy management without relying on cloud services [source]. It supports many EV charger brands, EEBus, OCPP, smart switches, heat pumps and electric heaters [source]. The main repo is written in Go [source].

Record

Measured (signals, n=4):

938 commits in 90 days across 1 energy repo [source].

17 distinct committers in 90 days [source].

Website at evcc.io [source].

46 open roles, but these are misattributed (see above) [source].

From the GitHub metadata:

The repo was created 2019-12-06 and last pushed 2026-10-14 [source].

It has 7,368 stars and 1,557 forks [source].

The org was created 2021-03-25, is based in Germany, is verified, and has 21 public repos [source].

The project was featured in PV Magazine and c't Magazin [source].

Inference: the commit pace and fork count point to an active open-source project. They do not show a company. Founders, legal entity, funding, revenue and customers are not in the evidence.

Why now

Market timing is not in the evidence. Inference: a German, local-first controller that works with many hardware brands fits households pairing solar with EVs and heat pumps. No demand data supports this.

Unknowns

Who the founders or core maintainers are: not in the evidence.
Whether a company exists behind the project: not in the evidence.
Business model, such as paid tiers or OEM licensing: not in the evidence.
Install base: not in the evidence. The README shows a Docker pulls badge, but no number [source].
Real hiring: not in the evidence once the evcc.com roles are removed.

Questions for the room

Is evcc a company or a volunteer project? Of the 17 committers in 90 days, how many are paid, and by whom?
What share of the 938 commits in 90 days came from the top two contributors? This tests whether activity depends on one or two people.
How many active installs are there, and does any installer or charger maker pay for the integrations listed in the README?

What would move the Skoor

It would rise with evidence of a legal entity and named technical founders, a verified install count, or paying OEM or installer customers. It would fall if the misattributed hiring signal is removed (Inference: to about 30), or if commits turn out to come from one or two volunteers.
