Open source EEBUS
enbility – The Open Source EEBUS Go Project
enbility maintains the Go implementations of SHIP and SPINE that let heat pumps, wallboxes, inverters and energy managers speak EEBUS — openly licensed, independently auditable, and in production today.

In short
01 / Who
A consortium, not a single maintainer
enbility is stewarded jointly by Coretech Innovations, EnQS, Kai Takac, Kontron eSystems and SPiNE — a carrier organisation committed to keeping the stack alive independently of any one company, building on the libraries Andreas Linde wrote and released in December 2022.
Meet the consortium02 / Why
Interoperability needs a readable reference
EEBUS is how German energy assets are meant to coordinate under §14a EnWG and §9 EEG. A closed stack makes that coordination unverifiable. enbility keeps one implementation that any manufacturer, grid operator or auditor can read, test and fix.
How EEBUS works03 / How
Running in about twenty minutes
Add eebus-go to your project, generate a device certificate, register the use cases your product supports, and pair against a real controller. The examples in the repository cover both ends.
Getting startedCode
The libraries
Three layers, each usable on its own. Most products only ever import the top one.
Data modelv0.7.0
spine-go
The data model. SPINE 1.3 of the EEBUS specification: entities, features, function types and the subscription and binding machinery that moves values between them.

Transport & trustv0.6.0
ship-go
Transport and trust. Certificates, mDNS discovery, the WebSocket connection, pairing and the SHIP handshake that two devices complete before they exchange a single value.

Consortium
Who carries the project
Each partner builds products that depend on EEBUS working properly. That is the whole governance model: the people who need the stack maintain it.
CompanySoftware and hardware for smart metering systems and energy assets in the German market — including the EnergyLink One gateway, which speaks EEBUS to SMGW, controlboxes, heat pumps, PV, storage and wallboxes on site.

Products and services around the stack
The libraries are free, and nobody sells them. What the consortium members do sell are the products and services around them — certified hardware, test capacity and implementation work.
EnergyLink One
The first box officailly qualified with the enbility EEBUS stack: limitation of power consumption and production in both roles — as the controllable system (CS/HEMS) and as the energy guard (EG, the German Steuerbox) — plus power and grid connection point monitoring and SHIP pairing. It runs alongside a local HEMS such as evcc, connects to a cloud HEMS, or is extended with your own applications and connectors through the SDK.

EEBUS integration, deployment and validation
Coretech helps manufacturers bring EEBUS into real products with deployment-ready eebus-go packages and extensive off-the-shelf use-case support, complemented by EEBUS simulation and automation, pre-qualification software, and training and technical consultation.

EnQS Testlab
A lab wired with real PV systems, battery storage, wallboxes and test smart meter gateways, reachable over VPN — where an EEBUS implementation or integration meets hardware that behaves like hardware, not like a simulator.
- Implementation testing
- Integration testing
- Remote access
Hardware built on eebus-go
Wallboxes, charging cables, inverters and storage that speak EEBUS through the same stack — and the option to have the electronics developed and manufactured for the job, from prototype to series production.
- Charging hardware
- PV and storage
- Custom EMS electronics
How does EEBUS actually work?
Two layers. SHIP finds the other device on the local network, establishes a mutually authenticated TLS connection and completes a pairing the user confirms once. SPINE then describes what each device is and what it can do, so a wallbox and an energy manager negotiate a charging limit without either having been built for the other.
What does enbility give me that the specification does not?
A working implementation of the parts that are tedious to get right — certificate handling, discovery, the handshake state machine, the SPINE model — plus a set of ready use cases covering EV charging, self-consumption optimisation and power limitation. You implement your device’s behaviour, not the protocol.

enbility relaunches: the consortium behind the open source EEBUS stack in Go
enbility has relaunched: a new website and a five-member consortium now maintain eebus-go, spine-go and ship-go, the open source EEBUS implementation in Go.
Thomas Müller23 December 2025enbility is moving forward — together
Over the past months, some in the community have asked whether enbility and the go-eebus stack are still actively maintained and what its future looks like. We want to be very clear:
