Mark,
Sorry for the delay but I actually found a better method for controlling our actuators. After your post I started thinking about a few options for you and then... I found it. So I even ordered one. Take a look and let me know what you think.
Control the actuator from your phone and it's not much at all, under ($20.00) If you have a Amazon echo or the Google thingy you can control it with voice commands. (Bridge up or Bridge down) but I would assume you should have limit switches with the voice function so the motor stops when it should.
