I'm new to this seemingly addictive hobby. Gonna have lots of questions. I started with one window, one ws2812b strip and one esp8266 with WLED. I can see this is gonna get expensive.
Welcome! Lots of good folks and help here. Make sure you read the 101 manual. It will answer a lot of your questions. Have you dug out of the rain, ice and snow yet?
It can get expensive but can be done a lot cheaper if you shop around and grab good stuff at the right price. The ACL101 is definitely the place to start working from.
