If you need a prototype (including wifi, mqtt and home convention) perhaps you take a look at my Christmas project.

May 2020 be as good (or even better) for all of you, your families and your projects. If you ran into the same problem as I did perhaps this could be a last minute hack - or a good preparation for next year you can do over the holidays.

The code for controlling 3 gpios (with pwm) is only a few lines. All the protocol stuff is done by the great homie esp8266/32 library.  
If you start perhaps consider to skip the Arduino IDE and take a look at vs-code + platformio. Looks more complex on first sight but all the coding tools are great especially for beginners.  
Don’t get confused: Arduino IDE is using the Arduino Framework. With platformio you “can” use the Arduino Framework too only with the more powerful vs-code ide.
