Identify all the cables - VCC, GND, and Signal - to facilitate the connection with the nodemcu. As the anemometer will be installed on the roof of the house, I also made 3 meters cables to connect it to the nod
microSD card support, on-board flash lamp and several GPIOs to connect peripherals. However, it doesn’t have a built-in programmer. You need an FTDI programmer to connect it to your computer and upload code.
Hello, I'm newbie. I'd like to send (MASTER - esp8266 nodemcu, SLAVE - board with relays -> SLAVE_ID = 2) this command: 0x0100 to this 0x0001 accumulator. I'd like to do it with these libriaes, but they don't work with esp8266 only with ...
Homie will publish temperature to a topic like : homie/5ccf7fd3945b/temperature/degrees (19.20) To enabled the LED, we have to publish a topic like : homie/5ccf7fd3945b/switch/on/set (true) My PiDome instance has a custom MQTT device created in order to access the DHT22 temperature ...
