So is like to see some other members inputs. D1Minis are great and ive used a few of them when i have 5/12v available. But for some of my projects ive just resorted to sonoff basics. A waste but cost wise makes more sense. If im running a single sensor and only need 4 pins the basic works great and I dont need to worry about powering the board as it has all the components to just connect to 220V.
What is your preferred ESP solution?
