After more than ten years, Smart Thermostat is no longer under active development and the Android app is no longer available for new installations. Maintaining a system that combines mobile software, cloud services, DIY electronics and connections to domestic heating equipment requires more time and resources than I can responsibly dedicate to it. For this reason, I have decided not to add new features, provide guaranteed support or recommend the project for new heating installations.
The existing documentation and resources will remain available as a reference for current users and for anyone interested in the project’s history and technical design. Existing installations may continue to operate, but the software is provided without any guarantee of future compatibility, availability or maintenance. Please do not rely on Smart Thermostat as a safety-critical system, and always consult a qualified heating professional before making changes to a boiler or heating installation. Thank you to everyone who used, supported and contributed to the project over the years.
Smart Thermostat will be permanently discontinued in June 2027. At that time, the project’s server infrastructure will be shut down and all features that depend on the online service—including remote access, account management and communication between installations through the server—will stop working. Existing users should therefore plan to replace Smart Thermostat with an alternative solution before June 2027.
