Martin Jerry MJ-SD01 (Single Pole PWM Dimmer)


The versatile single pole dimmer by Martin Jerry. No secondary MCU to contend with so you can easily control the buttons to do almost anything you want. There's no template needed when used with TASMOTA as it built right into the Configure Module selection screen. PCDiem as done a great job at documenting all the features he's packed into the device software here.

Need a 3 way version? Use this model with other dimmers/switches utilizing TASMOTA Device Groups

Martin Jerry sells the switch in both the Tuya Smartlife model or TASMOTA Pre-Flashed. Pre-Flashed is the way to go!

Purchase TASMOTA Pre-Flashed via Amazon
