Sinilink XY-WFMS

Sinilink XY-WFMS

Device Type: relay
Electrical Standard: global
Board: esp8266

This device can be found on Aliexpress for about 5 USD.

Flashing

alt text

Can be tricky to solder the ground connection to the PCB due to heavy ground plane, I used P50 pogo pins in a printed adapter for 6x1.25mm but the Vin- screw terminal could also be used for conveient ground connection.

GPIO Pinout

PinFunction
GPIO02Blue LED
GPIO04Relay and Red LED
GPIO12Toggle Button
GPIO13Green LED

Basic Config

The following configuration is adapted from https://github.com/esphome/esphome-devices/blob/main/_devices/Sinilink-XY-WFUSB-USB-Switch-Relay/Sinilink-XY-WFUSB-USB-Switch-Relay.md with only minor changes to fit the new device.

There is a 3D printable case available from https://www.thingiverse.com/thing:4638431 which I remixed from https://www.thingiverse.com/thing:4146127
