The ESP32-H2 microcontroller offers ultra-low power for Zigbee smart home devices. It draws just 20mA compared to the 77mA of the ESP32-C6.

In my early ESP32 tinkering days, I’d only use the microcontroller to test with LEDs, resistors, and other circuitry components. In fact, writing simple C++ programs to perform basic tasks on the ...

ESPHome is the sole reason I was able to build several ESP32 smart sensors without losing my patience ...
