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.

Hi

I am a little confused.
Why are you configuring the sensors as outputs, should it be input on the CC2530?

    Input/output does not matter for sensors. It is just a place for the settings.

Hi, i would like to build 3 devices with 6 sensors and 1 with 4 sensors. Is that possible or do only 4 sensors always work?
I once designed a PCB and presented it in the ioBroker forum

    You can add up to seven DS18B20 to your configuration.

      But I need the premium version for the number of devices and then 4 times, right?

        No, the free version allows you to add 7 sensors too. Please note, that all sensors should be on one bus, or you should specify the sensor ID in the settings for each channel.

Hi. I’m using Home Assistant with ZHA instead of Zigbee2Mqtt. Using the firmware as proposed here, device is connected (message received in log) but there is no “Entity” showing the Actual Value. Do you think I’m doing something wrong?

    It seems that ZHA has limited support for DIY devices, and I cannot help here.

Hi, I try connect 6 sensors like inputs, each sensor on own pin, but i receive data only from first sensor. I chose this solution because I want change sensor time to time so can’t set sensors IDs and use one pin (bus).

Is this configuration possible/supported?

Anyway, thank you a lot for great work, Tomas

Can DS18B20 used in the PSM, please?

    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.
