There’s a lot to like about this little remote, which is based upon a LilyGo TTGO ESP32 board with on-board display. The circuitry is basically that and a rotary encoder plus a tiny LiPo battery.

That knob there is a rotary encoder, not a potentiometer, because endless volume knob twiddling is just so much nicer.

The rotary encoder is particularly useful for adjusting settings like brightness and volume with ease, making it a convenient tool for enhancing home comfort and efficiency.
