Compatibility Alert
Alarm.com is choosing to end support for the 2GIG CT-100, the 2GIG CT-30, and the GE TSTAT-300 thermostats on any new accounts created or accounts recycled after May 27, 2018. Older accounts created before that date will not be affected.
Those devices do not meet the higher communication standards needed to support new thermostat capabilities. Those features, including HVAC Safeguards, add significant convenience and comfort for homeowners and dealers.
Instead of those devices, Alarm.com recommends you install any of the other thermostats listed in the Ecosystem.
