I recently purchased 2 43" Samsung Crystal 4k UHD TVs and hung them up on the same wall as my 65" 6 series TV(to maximize the college football season). One remote can change everything for each TV so I was looking for a solution to simply block the IR sensors on the 43" TVs and control those TVs through the SmartThings App when watching football on Saturdays. I've tried using electrical tape and nail polish, but that doesn't seem to work. Maybe I need to use more tape? Does anyone else have any tips to block the IR sensors? Thank you!
