What is it?

Device created on esp32s, the device has 4- relay 12A 250VAC, 1- 8 pin connector where there are 6 inputs and 2 GND, 1- 5 pin connector with 5V-GND-TX-RX-OUT, 1- connector 5 pins with 3V-GND-SCL-SDA-INT. The device is powered via PoE or also via 12V connector. the flash of the ESP occurs via the USB C port. The device was created mainly to be used via PoE but of course it can be used via wifi in this case it is advisable to use an external antenna to improve the signal.

Why did you make it?

I created it for a personal need that I think everyone has: decentralizing cable home automation. Personally I will use a device for each room where I will control a roller shutter, two light points, two door/window sensors, a T/H sensor, a brightness sensor and a presence sensor, then I will use a device to manage the heat pump, another to manage the VMC and another to manage the photovoltaic system by extrapolating the data from the various devices via bus.

What makes it special?

It is a very versatile device and has an extra edge because it has PoE
