I had been using the Trend sensor successfully for a while but it has now broken (possibly when updating to 0.82) with the following in the log file:
2018-11-17 16:39:21 ERROR (Thread-11) [homeassistant.util.package] Unable to install package numpy==1.15.3: Failed building wheel for numpy

You are using pip version 10.0.1, however version 18.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

This was a manual installation on a Raspberry Pi 2 in a Python virtual environment. Any suggestions on how I can get this working again?
Edit: I’ve been able to get it working again by manually installing numpy version 1.15.3 using the command pip3 install numpy==1.15.3 from the virtual environment, but I don’t understand why Home Assistant failed to do this.
