You’d need extra bits and pieces to monitor those things, or if the gate controller monitors those things already, figure out how to read that information.

You could add a current transformer around the motor conductors to handle the ‘is_moving?’ case. If there’s measurable current flowing through the motor leads, the motor is turning. That’s how you determine the on/off status of a fan or pump motor in a building automation system.

Magnetic contacts or end switches on either end of the gate could handle the ‘open’ and ‘closed’ cases. Magnetic contacts are widely used in commercial doors for access control, and end switches are used for air damper open/closed status in building automation systems, to give a couple examples.

Not sure about the ‘blocked’ case, that would depend on what the gate motor controller does when the gate is blocked. Some kind of sensor that uses the photoelectric effect, I would imagine.




The board already has all the limit detection. It just doesn't provide it at output pins.

Of course, the trend in consumer product interface is either nothing or a full web server with a "cloud" connection and an app. With ads.


I’ve poked at some BFT boards. The ones I’ve looked at do have outputs, but they’re configure oddly by default. You can go through the menu and reprogram them. Warning: the modes may not all do what the manual says. Test them. If one mode doesn’t do what you want, try another mode.
