I did one with an ESP32 mini. Then its set up as a IP Device under Ezlo.
Ezlo polls the ESP32 with a GET and then the IP template parses the response string to stuff the temperature reading into a temp probe device.
The code to read the sensor is trivial once you load the Dallas Semi library, just a couple lines to initialize and read the probe(s). Would be easy to make this native in Ezlo Pi.
Init Section:
#include <OneWire.h>
#include <DallasTemperature.h>
// Setup a oneWire instance to communicate with any OneWire devices (not just Maxim/Dallas temperature ICs)
OneWire oneWire(ONE_WIRE_BUS);
// Pass our oneWire reference to Dallas Temperature.
DallasTemperature sensors(&oneWire, ONE_WIRE_PULLUP);
sensors.requestTemperatures(); // Goes out and polls all the attached DS18B20 Sensors attached and each gets a row in the output
for (int i = 0; i < sensors.getDeviceCount(); i++) {
row = "Temperature P ";
row += String(i + 1);
}
