I made it so if I lower the movie canvas- the sensor aligns and the automation dims all the lights to 15% and turns the Beamer on. I Love how it works so flawlessly!

Such a great idea. How do you get it to switch on the projector though?
That’s a really amazing way to execute an automation that makes everything enjoyable.

Haha, thats really inventive. I would have tried to complicate things by monitoring the power at the screen or something, trying to turn a dumb screen smart… this does it so much more elegantly. Good on ya.

Great idea bro!
May I ask what product you use to up/down the canvas?
And Is there such a product that works with HomeKit?
Thx in advance!

Hi, how do I remotely turn on a projector? I have a several-year-old Epson that doesn’t integrate with HomeKit or other home automation platforms. I’m not sure how to turn it on—maybe using the original infrared remote? Does anyone know?
it depends on your projector. Does it have buttons? Then you can use something like a switchbot bot. If it uses RF or IR then you can use some type of programmable transmitter… the problem being is in both cases it is stateless. You can only assume the action has been taken.
