Martin Jerry Switch MJ-S01- Single Pole

 

The MJ-S01 Single Pole Smart Switch has long been one of my favorite smart switches for several reasons;  1. A red and blue LED that is controllable, which of course also makes purple.  2. Easy to open.  3. Little travel required for a button press.  4. Still Tuya Convert'able as of Dec 2020.  5. Several solderless serial flashing methods.

Don't forget to activate the template on the "Configure Other" screen!  

If a Red LED while Off and Blue LED while On is desired paste the following rule into the Tasmota console.  If you want opposite colors, edit the template in the configure template screen and transpose Led_i with Led and vice versa. The "i" stands for inverted.  Copy the below rule as one line to the Tasmota console:
