9. Why is the app rejecting the device Registration Code?

The Registration Code is valid for 30 minutes before it expires.

Double check that you are using the correct mobile app for the device. The Watts Home app is NOT compatible with the following equipment:

tekmarNet Gateway 486 (download tekmarNet Gateway app)
Smart Boiler Control 294 (download Watts OnSite app)

10. How do I share access to my devices to others, such as my family or building caretaker?

The person that creates a location and adds new devices becomes the location owner.

The owner can then invite other users to view and adjust the devices at that location by following these steps:

Select the + icon
Select Invite User
Enter the email address of the user and choose the user type
Select Send Invitation

The invited user will receive an email with a link to setup their Watts Home account and the location will be added to their list.

WattsHome Step 10

11. How does the Home/Away toggle work?

The Home/Away toggle lets you save on energy costs while you are away from your building location for a day or more. Simply set your location to “Away” and all thermostats operate at an energy saving setting for both heating and/or cooling, and the snow melting system has the option to not melt. Prior to your return, set the location to “Home” and all thermostats and the snow melting system will resume normal operation.

If the location is unoccupied on a predictable, repeating schedule, it is recommended to set up a schedule rather than using the Home/Away toggle.

If you have multiple locations, the Home/Away toggle can be selected from the location list.

20. I registered a device but now it’s missing:

There are different reasons for a missing device:

The device isn’t listed in the default location. Please check all your locations.
Somebody de-registered the device in the WiFi menu of the control.

21. The app shows that the device is not available. How do I correct this issue?

Check the Internet and IoT connection status on the device.

If the Internet is disconnected, check that the WiFi signal strength is between -10 to -70 dB, powering the router off and then on, and that “bandsteering” on the router is disabled.

If IoT is disconnected, the router may be blocking an outbound connection to the Watts cloud.
