IMPORTANT NOTE: As reported by a couple of users It appears that the Optoma GT 1080 does NOT work (even though it looked like it would from the manual). Users have reported that the Optoma S341 and BenQ W770ST DO work. Please post a comment below for any successes or failures which might help others with different projectors.
You can control an Optoma GT 1090 HDR just using Falcon Pi Player (FPP), a Raspberry Pi and the HDMI cord you already have attached to the projector. This is using the CEC (Consumer Electronics Control protocol) supported by some projectors (and lots of other devices).
Equipment Used (Amazon affiliate links):
Optoma GT 1090 HDR: amzn.to/3x1Nntv
Raspberry Pi 3 B+: amzn.to/3HvMiii
All the needed commands:
sudo apt install cec-utils
echo 'scan' | cec-client -s -d 1
echo 'on 0.0.0.0' | cec-client -s -d 1
echo 'standby 0.0.0.0' | cec-client -s -d 1
Below are the script files shown in the video, you can simply cut-n-paste the text into two text files named ProjectorOn.sh and ProjectorOff.sh. You can also get them already made from GumRoad in a ZIP file (enter $0 to make it free):
