Install the final project on the device by using the ESPHome addon on HA (might be required to connect the ESP on the PC that is running HA) Before proceeding with any of the two options, make sure to identify the right board and framework (opt) for your ESP device. Check the ESPHome...
Rather than replace everything in the clock except the display, [zst123] is using the existing circuit board and adding an ESP8266 to grab the time from the Internet. A custom driver board reads the current time displayed on the clock directly from the display itself and then the ESP8266 ...
在国家“西气东输”战略推动下,家庭燃气管道得到普及,可是老一代人对新事物接受能力有限,可能无法准确操作这些设备。尤其是那些子女外出的老人来说,他们独自使用燃气更容易产生危险。对此我们基于ESP32设计了居室燃气检测远程警报系统,用于监测燃气状态以及在燃气泄漏
