Satori

Open Satori Developer Hub

Build on the open grid stack.

Everything you need to integrate Satori: the open IEEE 2030.5 client, the SunSpec Modbus bridge, canonical device models, and the community that builds them.

The stack at a glance.

IEEE 2030.5 client

APACHE-2.0

py20305

The open-source client: mTLS, DERControl, telemetry, CLI runner. Supports 2030.5-2018/2023 and CSIP-AUS.

GitHub ↗PyPI ↗

SunSpec Modbus

APACHE-2.0

pysunspec2

Device-side library for Modbus over TCP, RTU, and TLS. Works with 80% of inverter-based products.

GitHub ↗PyPI ↗

DER canonical models

OPEN

sunspec/models

Inverters, batteries, EVs, and meters as IEEE 2030.5 / SunSpec objects. One mapping, all grid codes.

Model Viewer ↗GitHub ↗

IEEE 2030.5 standard

REFERENCE

Protocol & profiles

CSIP, CSIP-AUS, CSIP-Germany, CSIP-EU. Specification and profiles via SunSpec Alliance.

ROADMAP

Today: Python-based client on Linux and Docker. Future releases: C++ and firmware-friendly implementations to enable deployment on embedded systems, gateways, and microcontrollers. Same semantic mapping, different deployment contexts.

Module documentation

Deep dives by module.

PY20305 CLIENT

IEEE 2030.5 / CSIP

From pairing to production. Conformance testing, API reference, Docker deployment.

Quick Start → Discovery → Running → Connectors → Docker → Conformance → Testing → API → Reference ↗

PYSUNSPEC2 LIBRARY

SunSpec Modbus

TCP, RTU, TLS. Device-side library for the Modbus bridge.

Standards development

Five work groups.

Join the bi-weekly engineering call or pick up an issue. Work tracked via GitHub labels.

Protocol & Conformance

Client behavior, event engine, conformance testing.

Issues ↗

Modbus Bridge

Device discovery, register maps, secure Modbus sessions.

Issues ↗

Scout Reference App

iOS/Android app, pairing UX, device export. Commercial licensing available.

Issues ↗

Jurisdictions & Profiles

CSIP, CSIP-AUS, CSIP-Germany, CSIP-EU. Configuration, not forks.

Issues ↗

Docs & Tooling

Quick starts, API docs, SDKs, developer tools.

Issues ↗

Meetings

Two cadences.

USER GROUP

FAQs

Frequently asked questions.

  • What exactly is open source?

    ›

    The IEEE 2030.5 / CSIP client (py20305) and the SunSpec Modbus bridge (pysunspec2) are Apache-2.0: royalty-free, including on gateway, EMS and HEMS products.

    Satori Scout, the reference iOS/Android app, is free for everyone (App Store, October 2026); its source code is available under commercial license for OEM, aggregator and VPP app integration.

  • What devices can I connect?

    ›

    Any UL 1741 SB certified device that speaks SunSpec Modbus: TCP, RTU or TLS. That's the vast majority of inverter-based products shipped globally.

  • Do I need to change device firmware?

    ›

    No. Point py20305 at the device's Modbus port and it becomes a compliant IEEE 2030.5 client: registration, discovery, control and telemetry with no firmware change.

  • Which IEEE 2030.5 versions and profiles are supported?

    ›

    2030.5-2018 and 2030.5-2023, with CSIP and CSIP-AUS application profiles. CSIP-Germany and CSIP-EU profiles are community maintained.

  • How are certificates handled?

    ›

    In-band registration over the IEEE 2030.5 session: SunSpec PKI production or test certificates, or bring your own operator/aggregator CA chain.

  • How do I get help?

    ›

    Start with the module documentation and the Quick Start Guide, then the User Group. Bugs and feature proposals go to GitHub Issues ↗.

  • Is there commercial support?

    ›

    DER Security offers a supported enterprise distribution and hosted head-ends. Email satori@dersec.io.

  • Where do I report a security issue?

    ›

    Email satori@dersec.io directly; please don't file security reports as public issues.
