Terms of service

Last updated: 17 October 2026

P4Thermo is a personal, experimental ESP32 integration for an owner-controlled Google Nest thermostat. It is not offered as a commercial service.

Use is limited to devices and Google accounts for which the operator has authorization. The integration depends on Google APIs, internet connectivity, and the existing thermostat's safety controls.

P4Thermo is provided as-is without a guarantee of uninterrupted operation. The thermostat’s original safety systems must remain in place; the ESP32 controller is not a safety-critical heating controller.

Google Nest and Google Cloud are products and services of Google. P4Thermo is an independent personal project and is not affiliated with or endorsed by Google.
