During setup, Circle will look for devices that should be Unmanaged and pre-select them to avoid issues on your network. Unmanaged Devices are ignored by Circle to ensure that none of your sensitive or smart home devices accidentally get Paused or Filtered. Circle should ignore the following:
Smart thermostats or smoke detectors
Wi-Fi enabled outlets or light switches
Sensitive Wi-Fi controlled equipment
Other smart home devices
See "Devices" to Assign or Reassign a device as Unmanaged.
