Attention iPhone users: iOS 15.0 through 15.2.x contain bugs that affect the auto-open feature. Versions above or below work fine.

Door sensors don’t work when garage door auto closes

    Hi Brian,

    Tailwind will automatically try a second time to operate the door if it detects that any open or close event was unsuccessful. In the case of opening, this occurs in rapid succession - about 5 seconds later. For closing it is about 45 to 60 seconds depending on the firmware installed. This happens regardless of how the command is initiated within the Tailwind ecosystem. So if it's a timer based auto-close, driving away, tapping the door icon in the app - they're all the same. It will try to close the door. If it detects the door did not close it will try again 45 to 60 seconds later. If that fails again, it will lock out for safety reasons as required by the safety standard UL 325.

    When Tailwind sends the command to the garage door opener, the standard pulse duration is 1.5 seconds. That is equivalent to holding down the wall button for 1.5 seconds. The only thing I can think of is that you were passing your foot through the beam during that 1.5 second time period. Garage door openers are typically programmed such that if you want to close the door and the safety beam is interrupted, you have to hold the wall button down for the entire time the door is closing. Then it will override the safety sensors.  If you release the button, the safety sensors become active again.

    If for some reason your garage door opener is continuing to close the door and not responding to the safety sensors being interrupted after 1.5 seconds, that's not normal. You could try shortening the pulse time to something like 300mS or 400mS to see if that helps. If you make it too short, the opener won't respond reliably.

    Here is a video showing how to change the pulse settings (and set the partial open command if that interests you)
