Compatibility with Sky Panel and Alarm.com

We do have a sky panel so I would have to get a new panel but would all my sensors and thermostat work with your panels?

The Sky Panel utilizes the 345Mhz communication protocol between the sensors and panel. If looking for direct compatibility, look towards the 2GIG Go!Control and 2GIG GC3 panels, both of which utilize the 345Mhz frequency.

Do you know the model numbers/names of the sensors you have? What is the make and model of the thermostat?

Note that the DW11 and DW21 sensors are unlikely to work with the 2GIG Go!Control or GC3 as they are proprietary sensors, only compatible with the Sky Panel. For more information please see this post and this post here.
