Completed the survey then started thinking,... In my previous life I provided testing support for new products, then my brain got tired and I retired to focus on more important aspects,... My last employer bothered me for a few years to come back for this or that, but I was busy. After completing the survey (good job on that) I decided to check on what hardware might be available to do something like remote control a switch. On mouser I found a Bluetooth development kit that looks interesting so if you actually do proceed then perhaps you might consider the hardware side too.
Anyway, good luck in your research,.
