I like having a small smart home setup build around Home Assistant. Simple automations, voice controls and other modern features are nice, but I still want regular controls for lights (in addition to smart features).
I made simple light dimmer using ESP8266 which I configured using ESPHome. This works hand-in-hand with Home Assistant's controls: Even if brightness was changed by another device, this knows what current brightness is and manages to adjust it in small steps.
SOURCE CODE, added some rounding, filtering and maybe other things for reliability and stability:

HARDWARE: There isn't much, I selected D1 mini's D5 and D6 for the A and B pins of rotary encoder, encoder's common pin is connected to ground.
