Hi folks - new here so hope I am conforming to protocol with an ask for feedback:
I built a very basic controller for my 12V landscape lights. It uses a prebuilt 10A 12V power supply with 2 leads each of + and ground. These leads feed the input of 2 MOSFITs and the output of each MOSFIT is 8 x 12V 10W lights in parallel. The pre-built MOSFITS are controlled each by a pin on an ESP8266 in PWM mode so that the integrated application (ESPhome for HomeAssistant) can control on / off and brightness with the YAML code used in that application. I used a step-down converter attached to one of the 12v leads and ground to feed the ESP8266 it's 5v. It works remarkably well but I wonder if there are any things I should consider like fuses at the + leads? Parts are basically from Aliexpress - MOSFITs, ESP8266, PS and step-down converter.
