Abstract
ESPHome configuration to drive LC-Technology relay modules. Tested on a 12V 4 channel version with nuvoton MCU. See detailed writeup of this project in my blog:
Running & flashing
esphome xxx.yaml run
Configs
This repository contains 2 sample configs
- gatekeeper.yaml
A config I used to drive Nice Flor-S remote control buttons.
- relay-simple.yaml
A config that just exposes all relays for your fun.
- relay.yaml
Same as the above, but with LEDs and buttons. Needs alternative nuvoton firmware
nuvoton firmware.
Stock firmware only supports relay control. I've also created an alternative firmware for nuvoton MCU that exposes three LEDs with PWM (RGB) and reports button states. You'll need nuvoton's ISP and a Windows box (or a VM) to flash it. I used linux to develop the firmware and a windows box to flash it.
Just grab the firmware.hex from here: https://github.com/nekromant/lctech-relay-altfw
