I’m just getting into SmartThings and have a handful of devices already connected. My next thing to learn is how to hookup multiple inputs without using a $40 sensor for each input just to check open/close status on each, maybe using something like an Arduino board (I have zero experience with Arduino). I’ve read enough to know that ST eliminated the SmartThings shield, so it’s now more difficult to make this work with ST.
While doing some research, I ran across an Arduino project where someone hacked their heated mattress pad (similar to the EightSleep Mattress pad elsewhere on this forum). I was intrigued with this because I have the exact pad that was used and would love to do a similar thing, but also connect it to ST. The project is 4 years old, so the links for the parts no longer work.
Here’s my question for those of you that know the Arduino world - Is something like this easily accomplished using the Arduino products currently available? Once that’s accomplished, how difficult would it be to connect to ST?
