Hello, where can i find this library ??? Working library is available here: https://www.b4x.-dallas-1-wire-protocol.66672/ rWireOne thanks for help kind regards from gemany

Try with pin GPIO2 https://www.makerguides.com/esp32-ds18b20-digital-thermometer/

Not so simple and the exact details depend on the way the array is created and who is expected to release it. There are several libraries and related threads: https://www.b4x./?query=b4r+dallas If they don't help then post the not working inline C code.

Would be nice to choose something where a plastic project box is available and maybe a small lcd screen later (although we'll write a B4A app to display the data) The m5stack boards look very easy to start with, but I think I read there is some incompatibility with B4R ? The temperature sensors see

Looks great, nice work! I would make the distinction that I2C is two wires and SPI is usually four wires. Also, add a reference for the Dallas One Wire Protocol. A lot of temperature sensors use that. https://wiki.seeedstudio.com/One-Wire-Temperature-Sensor-DS18B20 <<< IMHO I will add, the part

the resistor is needed to cut back the 2 wires (one wire hug?) capacitance and thus create a network termination. many sensor have this resistor internally. one thing you do not mention is at what distance is the sensor from the controller, and what type or cable did you use to connect the sensor.
