In this IOT world we need a simple way of sending data to a hub. Welcome to ESP-NOW. JLCPCB Only $2 for PCB Prototype any colour including aluminium. It was brought to my attention by a viewer that ESP-NOW is a protocol ideally suited to sending out small amounts of data (up to 250 characters) so I just had to experiment. With an ESP32 receiver and an ESP8266 transmitter I modified the sketches written by @Rui Santos and which worked well. It was obvious that I could use this approach in my unified workshop “smart“ heater controller. Watch the video for further ideas and a working example (that you can get working in about 15 minutes)! ► Modified sketches (Arduino IDE) for the sender and receiver in my GitHub Click on ANY of the Banggood links below *before* visiting them to support this YouTube channel! ► ESP8266 modules ESP-01 simple unit ideal as a sender $4 Geekcreit® Wireless NodeMcu Lua C
