Hi,
I wanted to share my latest project. This is a board with 16 SSRs, ESP8266 module and MCP23017 chip. Therefore, it can be controlled by WIFI or I2C. Home Assistant and ESPHome work beautifully with MCP23017. Integration takes 3 minutes :slight_smile:
Details of this project, all source files and a step-by-step guide can be found here:

Great project and website that you have there.
I’m looking for something similar, but with a LAN cable connection.

Perhaps a remix with an esp32 and https://esphome.io/components/ethernet.html

It’s actually a great idea! I didn’t think to use LAN for communication but I like this idea very much :slight_smile:

There are also POE esp32 boards, making a neat solution.
