Hi everyone! I want to connect an AC dimmer to an Arduino to control the brightness of several 800W 220V incandescent lamps (for a chick brooder). Which dimmer should I choose? The documentation mentions two libraries, which one is better? 
I plan to use an ESP32-WROOM module.

Thanks for the response!
Is it possible to use a dimmer with infrared heater?

Yes, can.
Common dimming, same heater or indicate bulb

Sven. For ESP32, it's optimal to use the new rbdimmerESP32.h library. We plan to release updates for this library, along with more code examples and projects. This should assist you in your project.

Hi Sven! For 800W, an 8A dimmer would be optimal. You might also consider a 4-channel dimmer. If the room is warm, adding a fan to cooling from the dimmer enclosure would be beneficial.

There's a new library available for ESP32, though I haven't used it yet. RBDDimmer claims it utilizes ESP32's hardware resources, reducing the MCU's load. I've been using RBDDimmer with ESP8266, and it works fine.
