ESP8266 and ESP32 Boards Support

andrew

Sketches have been updated to work with ESP8266 and ESP32 boards. So far I have used the HiLetgo boards on amazon. These boards use less power and I am testing them out on my Solar Shed.

Sketches should be downloaded from monitor.brewbench.co but I have some notes on BrewBench's github

You'll need to download a driver to see the board in the Arduino IDE and upload the sketch.

And add some libraries to your board manager URLs

Any additional instructions for using the esp8266. Cant get mine to recognize my DS18B20 probe. I had seen something where with the 3.3v system you should use a different resistor anyone notice this?

Thanks
Chris

I have use 4.7K resistor, maybe this project will help https://www.hackster.io/adachsoft_com/esp8266-temperature-sensors-ds18b20-with-http-server-5509ac
