How to make a Smart Motion Sensor out of a Night Light Smart Plug.  An excellent solution to easily put a motion sensor in a room where you couldn't before for automated lights. You also get a night light and smart plug in the same package for less than $20!

Parts List
Smart Plug - iMah or iClever 
PIR Motion AM312 Sensor - 2 pack or 1 pack

Soldering Iron Station
Helping Hands(as shown)
Better Helping Hands
0.015 Solder
Female Jumper Wires
USB FTDI for Flashing

Did a rather short (sarcasm) live stream showing the process to break open the smart switch, identify features, flash tasmota, setup the template, etc. It was my first time doing this switch model and first time doing the real live stream.

I also showed the bonus of the very cool new dimmer switch I've been working with on and off. It's very close and works out of the box right now as it is with a few Tasmota rules.

Had a lot of fun and let me know if you'd like to see more of these (hopefully shorter next time!)
