Symptoms
- App shows the garage controller as offline
- Remote open/close commands don't work through the app
- Controller status light shows an error or unusual pattern
- Notifications about door status stopped coming through
Likely causes
- CommonLost Wi-Fi connection at the controller's locationGarages are often at the edge of home Wi-Fi range, especially with metal doors and walls.
- CommonController lost power (tripped outlet, unplugged, breaker off)Most smart garage controllers need continuous power to stay connected and report status.
- PossibleRouter settings changed (new password or network name)A network change disconnects the controller until it's reconnected through setup.
- PossibleSensor accessory (door position sensor) has a dead batterySome controllers use a separate battery-powered sensor to detect door position, which can go offline independently.
- Less commonController hardware failureAfter years mounted near a garage door opener, vibration and temperature extremes can affect electronics.
What to do
- Check that the controller is plugged in and has power, resetting any tripped outlet or breaker.
- Confirm your home Wi-Fi signal reaches the garage adequately; consider an extender if it's weak.
- Power-cycle the controller by unplugging it for 30 seconds.
- If you changed your Wi-Fi password or network name recently, reconnect the controller through its app.
- Check the battery on any separate door position sensor and replace it if low.
- Restart your router as well.
- Re-pair the controller from scratch in the app if it remains offline after a power and Wi-Fi check.
