If a Smart Vent is offline, or going offline intermittently, it's most likely that the battery holders are not tightened or aligned properly. This can produce a gap where the batteries are not secure. Try tightening the battery holders.
Another reason a Smart Vent is offline, or goes offline intermittently, is signal range to a Gateway Puck. All Smart Vents (and Sensor Pucks) need to be in range of a Gateway Puck to communicate using RF (radio frequency) signals. Check statistics to see if the Smart Vent is in good signal range of a Gateway Puck. You many need to convert a Sensor Puck to a Gateway Puck to increase RF signal range.
Try entering Setup Mode to discover Smart Vents:
- Tap the PLUS sign and select "Add new Smart Vent" to put the system into Setup Mode
- Allow five minutes for Flair to rediscover the Smart Vent
- Tap "Exit Setup Mode" to exit
If the Smart Vent is not discovered Setup Mode, try these troubleshooting steps:
- Does Gateway Puck WiFi icon show good signal strength? If not, move it closer to WiFi to improve WiFi signal strength. The Gateway Puck may be having trouble communicating with the Flair app.
- Check the statistics to see if the Smart Vent has good RF signal strength to a Gateway Puck. If not, then try converting the closest Sensor Puck to a Gateway to see if that improves RF signal range.
Moved Gateway Puck
If you've moved a Gateway Puck, this can affect its RF signal range to Smart Vents and Sensor Pucks.
- Try power cycling the Gateway Puck, and then enter Setup mode to rediscover the Gateway Puck.
- Try moving the Gateway closer - was it moved too far away?
- Try “Unlink Sensors” on the Gateway Puck in the Settings menu (the "gear" icon), and then enter Setup mode to rediscover Pucks and Smart Vents.
- Try resetting the Vent by power cycling it (being sure to wait 60 seconds with battery out), then enter Setup mode to rediscover Smart Vents.
