How to communicate with multiple boards from esphome to espnow An espnow gateway for receiving data from boards that transmit different structures!
Below is an explanation video! Sorry, it's in Korean!
- Upload nockanda_espnow.h to ESPHOME!
- Register the board in ESPHOME, edit the contents of the 3.espnow_gateway.yaml file to suit yourself, and upload it!
- Prepare the first board, connect dht11, and upload espnow_node1_dht11.ino file!
- dht11 has 2 float data!
- Prepare the second board, connect mhz19, and upload espnow_node2_mhz19.ino file!
- mhz19 has 2 int data!
- Prepare the third board, connect pms7003, and upload espnow_node3_pms7003.ino file!
- pms7003 has 3 int data!
- At this time, you must change the mac address of the gateway in the file to your own!
- Upload sensor data with different data formats from 3 boards to Home Assistant!
- Press a button in Home Assistant to turn the board's built-in LED on or off!
