My latest gadget! It's a thermometer that shows inside and outside temperatures as expected, BUT it sources and averages the values from several ZigBee thermometers in my home through Home Assistant.

It uses an ESP32 and an e-ink screen. Updates are periodical, so in-between updates the thing barely uses any power. Portrait and landscape orientations available!
