This device uses WR3E module which needs to be replaced with ESP-12 or ESP-07 module. Besides the module, this process will require a heat gun, soldering tools and moderate soldering skill.

Requires configuring shutter support.

Originally has a RTL based WR3E Module, changing it to a ESP-12S does the trick, no other changes, except maybe you want to populate the two other LEDs but it’s not necessary. Bad circuit: opening the plate will expose contacts with live mains! Some emit a high tone when a relay is active. Front button plate is 55x55mm and will fit e.g. in German standard switch plates, although the matte optics may not fit to the rest.

Real Pinout:

  • 0- LED3/R18, not populated
  • 1- NC
  • 2- NC
  • 3- Relay for contact marked L2
  • 4- LED2/R17, not populated
  • 5- LED1, a blue one visible through a hole
  • 12- S2, the center “On” button
  • 13- S1, the “Up” button, PCB marking “open symbol”
  • 14- S3, the “Down” button, PCB-marking “close symbol”
  • 15- Relay for contact L1
  • 16- NC
  • 17- NC

I’ve set the template so that there is a dummy relay on GPIO2, so the LED can be Link and another function switched with the center button. I use it to switch Automatic and Manual mode, hence the WebButton rename command. L1 is connected to motor “down”, L2 is “up”.

Additional setup:

SO80 1; SO1 0; PowerOnState 0; WebButton 1 Auto; ShutterRelay1 2; Interlock on; Interlock 2,3; ShutterMode 1; ShutterButton1 2 up; ShutterButton1 3 down

I’ve some used without MQTT in standalone Timer mode, the center button then is used to disable timers. To do this I added a simple rule

rule1 on system#boot do backlog power1 1; timers 1 endon on Power1#state do timers %value% endon

this switches the timers on when power is applied, and they follow the Power1 state.
