The firmware supports up to 4 sensors on one line. If you didn’t specify the sensor ID in the settings, the firmware sends all values to one endpoint but with a different description like “C,00-00-00-00-00” (unit, comma, device ID).

You may specify the same pin number, sensor type, and sensor ID on different endpoints. In this case, the firmware will send the sensor value to the corresponding endpoint.

Here is a great tutorial with four DS18B20 sensors and HA integration.

    Yes, you can. But you should connect the VCC line of the sensor to P10 or P11 pins and configure External power control for this sensor.
