Use an Alarm.com Temperature Sensor with an Alarm.com Smart Thermostat

To pair a Temperature Sensor to a Smart Thermostat using the Alarm.com customer website:

1. Log into the Alarm.com customer website.
2. In the Thermostat card, click .
   
   
    
3. In Sensors, click to select the desired thermostat(s) and Temperature Sensor(s).

To pair the Temperature Sensor(s) to a thermostat schedule using the Alarm.com customer website:

1. Log into the Alarm.com customer website.
2. In the Thermostat card, click .
3. Click Schedules. 
4. Click  next to the Thermostat Schedule to be edited.
5. Next to the name of the device for the desired mode, click .
   
   
6. In Choose Temp Sensors, click to select all of the desired sensors for the mode. 
   
   
    
7. Click Ok. 
8. Repeat the same selections for the other modes. 

Can the Temperature Sensors be used in auto mode? 

Yes. The Temperature Sensors have built-in safeguards to prevent the system from running too frequently or trying to switch back and forth between Heat and Cool too rapidly. However, it’s a good idea to verify that users have their Heat and Cool schedules configured to ensure a safe gap between Heat and Cool target temperatures at any given time. There should be at least a four-degree difference between the Heat and Cool target temperatures at all times to ensure the system is not cycling too frequently between them.

Can multiple Temperature Sensors be used with a multi-thermostat system? 

Yes, but things can get complicated quickly with multiple Temperature Sensors and multiple thermostats. The user experience is designed to be as simple and easy as possible, but when working with three thermostats and five Temperature Sensors placed around a house, managing all of them while trying to maximize the HVAC system’s energy efficiency can be challenging. Safeguards have been added to prevent Temperature Sensors from being used for multiple devices at the same time and to prevent systems from contradicting each other (and running Heat and Cool simultaneously, for instance). In general, it is recommended to start simple and build out as the user gets more experienced.

Why is N/A showing on the Temperatures card? 

Until Alarm.com has received a temperature report from a Temperature Sensor, the Customer Website won't have anything to show on that card. To prompt a temperature report, change the temperature of the Temperature Sensor by a degree or press the button on the side of the Temperature Sensor. Shortly after that’s done, a temperature displays on the Customer Website.

Can a Remote Temperature Sensor be used with any Z-Wave thermostat or is the Alarm.com Smart Thermostat required? 

Without the Alarm.com Smart Thermostat, it is still possible to see the current temperature in your Temperature Sensor’s location and use that to inform your decision when selecting a target temperature. However, for full functionality, including pairing Temperature Sensors for direct control, temperature averaging, and scheduled automation, an Alarm.com Smart Thermostat is required.
