Puck or Smart Vent is Offline
If a Gateway Puck is offline, please check out the article on Gateway Puck WiFi Connection.
Sensor Puck or Smart Vent
The most common reason a Sensor Puck or Smart Vent is offline is poor signal strength to a Gateway Puck. A Gateway Puck uses RF - radio frequency - signals to communicate with other Flair devices in your home.
Check the signal strength of the devices. If the signal is low, try moving the Gateway to a more central location, convert a Sensor Puck to a Gateway Puck, or add an additional Gateway Puck to facilitate signal strength.
Tighten Smart Vent Battery Holders
The second most common reason a Smart Vent is offline is that the battery holders may not tightened enough, producing a gap that prevents batteries from making a good connection. Try tightening the battery holders.
Be sure to wait 60 seconds before replacing batteries to allow the capacitors to drain.
Check to see if the Puck is responsive by pushing and scrolling. If the Puck is not responding to button pushes or scrolling, try the unresponsive Puck troubleshooting steps.
For Sensor Pucks and battery operated Smart Vents, try replacing batteries with fresh, new batteries. If you do replace batteries, wait 60 seconds before replacing.
You can reset a Sensor Puck's connection by going into the Settings Menu and selecting Unlink Gateway. You can reset a Smart Vent's connection by removing the batteries, waiting 60 seconds, and then replacing the batteries. Then enable Setup mode to discover and re-link these devices.
