Frequently asked questions and possible issues you may face when working with Cloud4RPi:

How to avoid an Installation Error?

You can get one of the following errors while installing the Cloud4RPi client library using the sudo pip install cloud4rpi command:

  1. InstallationError: Command "python egg_info" failed with error code 1
  2. Error while finding spec for 'pip.__main__' (<class 'ImportError'>: cannot import name 'IncompleteRead'); 'pip' is a package and cannot be directly executed

This happens because the setuptools and/or pip packages your Python interpreter uses are outdated. Update the packages with the following command:

sudo pip install --upgrade setuptools pip

After updating, reinstall cloud4rpi:

sudo pip install cloud4rpi

Raspberry Pi does not recognize my 1-Wire device

If you experience issues with the 1-Wire interface on Raspberry Pi, follow the instructions below.

  1. Run sudo raspi-config and make sure that the 1-Wire interface is enabled (Interfacing Options | 1-Wire menu).
  2. Add the dtoverlay=w1-gpio string to your /boot/config.txt file (echo dtoverlay=w1-gpio | sudo tee -a /boot/config.txt).
  3. Reboot (sudo reboot command).
  4. Double-check the wiring and your device's operational voltage. The 1-Wire DATA bus should be connected to GPIO4 (Pin 7) and pulled up to VCC.

How to avoid the "Insecure Platform" warning?

The InsecurePlatformWarning: A true SSLContext object is not available... notification appears when you run Cloud4RPi on a Python version lower than 2.7.9. Check your current Python version with the following command:

python --version

You can install the latest version using one of the following ways.

Where are the log files?

You can read the logs containing the service's output and errors using one of the following commands:

  • less /var/log/cloud4rpi.log — if your init manager is init and you have left the service name and log path unchanged;
  • sudo journalctl -u cloud4rpi — if your init manager is systemd and you have not changed the service name.


Use the ps -p 1 command to see your operating system's init manager. If it differs from init and systemd, refer to the documentation for your init manager to learn about its logging capabilities or contact us.

You can also call the following function at the beginning of your script to save the script output. It is useful if you do not run your Cloud4RPi-enabled script as a service:
