Alarm.com Ending Support for 2GIG CT-100, CT-30, and GE TSTAT-300 Thermostats
Accounts created before that date are unaffected and may continue to use these devices.
Why Support Ended
These thermostat models no longer meet the updated communication standards required for modern Alarm.com features. The loss of support is linked to the rollout of advanced capabilities such as HVAC Safeguards, which provide homeowners and dealers with greater protection, convenience, and comfort.
Recommended Alternatives
Instead of continuing to use discontinued models, Alarm.com recommends upgrading to supported devices from the Alarm.com Ecosystem. These newer models are designed to integrate seamlessly with modern security and automation systems while offering enhanced efficiency and smart home compatibility.
