This project consists of two device builds... an IR transmitter and a bed occupancy sensor using ESPHome that I used for local AC integration and automation in Home Assistant. But either device has a multitude of potential other uses for your own projects.

You can find full wiring diagrams, stepbystep details and more in my related blog article: https://resinchemtech.blogspot.com/20...

Parts List:
==========
These are the parts that I used for my build. Some are optional and some can be substitued. I've broken the parts out by the two diffent builds, with a section that is common to both.
