ESPectre
Open-source firmware
Use, study, modify, and redistribute ESPectre while complying with GPLv3, including the corresponding-source obligations that apply to firmware and applications containing it.
Commercial licensing
Embed ESPectre’s shared sensing layers in proprietary ESP-IDF firmware under separate commercial terms.
FOR PRODUCT TEAMS
Choose the licensing path that fits your firmware.
ESPectre is available under GPLv3 for open-source use. A separate commercial agreement is available when GPLv3 source-disclosure obligations do not fit a proprietary product.
TWO PATHS
Open source or proprietary.
The sensing engine is the same; the obligations and permitted distribution model differ.
Proprietary firmware
Discuss separate terms for embedding eligible ESPectre core, runtime, Native, Matter, or Streamer material without applying GPLv3 source-disclosure obligations to your proprietary integration.
ESPHome remains GPLv3
The ESPHome C++ frontend combines with the GPLv3-only ESPHome runtime and is not part of the commercial firmware SDK path.
INTEGRATION SCOPE
Add sensing without handing over your product architecture.
Your firmware can keep ownership of product behavior while ESPectre supplies the reusable sensing path.
Sensing engine
CSI capture, calibration, detection, runtime events, and the supported shared integration layers.
Product behavior
Boot, networking, storage, OTA, UI, application logic, and the way motion events affect the product.
Defined agreement
Commercial coverage is limited to material the maintainer can license and does not replace third-party license, trademark, or media terms.
ENGINEERING SERVICES
Integration support for product firmware.
Optional engineering services can help product teams integrate, validate, and adapt ESPectre within an existing ESP-IDF firmware architecture.
Architecture review
Identify the appropriate SDK boundary, detector profile, resource budget, and ownership split for the product.
Firmware integration
Support CSI capture, runtime lifecycle, event mapping, build integration, and adaptation to product-specific services.
Validation and tuning
Evaluate CPU and memory use, reconnect behavior, sensing performance, calibration, and deployment-specific constraints.
Engineering services are scoped and quoted separately. A commercial license does not include support, maintenance, or service-level commitments unless they are expressly included in a written agreement.
NEXT STEP
Tell us what you are building.
Share the ESP32 target, the ESPectre layers you expect to use, whether the firmware will remain proprietary, and any integration support you need. Do not include credentials, pairing codes, or device secrets.
