Description
This is my most used switch in the house (at least in the winter). I started with a $80 Z-wave switch an had reliability issues. Below is my DIY solution that has worked without fail now for 3+ years. I use Tasmota firmware on an ESP-01S with components below for less than $10. Future options could include incorporating a rechargeable battery.
