In this Projekt we use the NodeMCU V3 because the cheap price and performance. You can use a smaller chips too, but i only had some NodeMCUs !
I made this simple Sketch with Fritzing:
For the Power i used some old Laptop battery pack, which works perfekt for me. For Powersaving you can set the NodeMCU in sleep mode!
