Hi guys , I couldn’t really find some concrete code on how to flash my Node MCU connected to a 4 channel relay switch currently running on Tasmota so after using integrating various codes off the ESPHome cookbook, here’s some code to help anyone who may be stuck :slight_smile:

You have inputs and outputs defined on the same GPIOs. That won’t work.

Do you have buttons connected to the device? If not get rid of the binary sensors.

Thank you , I do not have buttons , so is the output the switch function and input the binary sensor?

Correct. The switches will show up in Home Assistant.
