When to turn mirror on and off?
-
fun challenge… sorta need two sensors… one outside to detect coming in, and one inside to detect going out… that one inside needs a fast response time, as u need the info up long enough to be useful…
I have my mirror using motion and wake up all the time on any motion… but have it on short sleep time (2 mins), so it goes to sleep fast… pi/sbc is still running, so at most you are saving a small amount of power for the monitor.

I have been thinking about this also over the past couple of days, you could add a camera for facial recognition. I think that’s what I’ll look into so that mine doesn’t turn all on all the time and display all my info.

Or, a voice command to wake the display (when in standby) and voice command to put the display into standby (when awake).
Then, a voice command for each set of modules (pages). One page for each family member displaying their very own set of modules.

@mykle1 this would actually be a good module to add, I’ll look in to it, I’m taking the plunge this weekend finally to build one so I’ll see how it goes and report back.

Good luck, my friend. You will likely have some delay if you’re using a Pi. If you’re using something more robust than a Pi you will certainly have a better, more enjoyable experience. :-)
