Modular WiFi-Switch

Modular ESP8266 Wi-Fi switch to the installation in switch boxes.

Similar projects worth following
The WiFi switch consists of three PCBs.

Part 1 = Switch and Display
Part 2 = WLAN and Logic Stuff
Part 3 = Power and Powerswitch
As a basis I use a switch from "JUNG":

Frame: "AS 581"
Switch: "AS 506"

The PCBs are compatible with other switches with EU standards like GIRA, Becker ... up to Part 1 since the PCB is different in size, I will test this later.

Status for the three PCBs:

  • Board and Schematic - Part 1/2

    A bit more I have done now, Part1 is so far finished and can be ordered, minor improvements are still missing.

    I have decided for two Capatzitive buttons which are controlled with an AT42AT1010, as a first display is a 0.96 "OLED which can be replaced by a 1.3" OLED.

    I have noticed something to buildability and the components so that they can be soldered by hand.

  • Part2 - Tested

    Part2 is tested and functional, add PCB data to the Downloads

  • Part2 - Arrived

    Arrived by OSH Park, looks really chic, unfortunately I will come in the coming days for placement and testing.

    A small drawing as I imagine, the switch box has a depth of 60mm, the PCB stack sticks ~ 26mm inside, ~ 34mm left for the cabling.

    I'm planning on Part 1 (Switch and Display), Part 2 (WLAN and Logic) is Ordered at #OSHPark.

    So I have to be patient.

How do you plan to power this unit? Is a neutral wire in the switch box necessary?

  Are you sure? yes | no

I plan two different power modules, one for 12V and one for 110V-230V this will need the neutral conductor.

  Are you sure? yes | no
