I am using a custom climate component for a Fujitsu Heat pump https://github.com/xerxes87/pyfujitsu_for_homeassistant which requires an additional Python package pyfujitseu to be installed. The maintainer of the component has included this requirement in the component manifest but unfortunately this isn’t working. He has requested help to fix this here https://community.home-assistant.io/t/custom-component-requirement-not-installed/199144 but hasn’t had much luck.
With Home Assistant Supervised it is possible to ssh into the Docker container and use pip to install the package manually.
I am in the process of moving to running Home Assistant OS running in a VM and have found I can no longer do that. Under 0.112.4 I found I was able to manually add the package in deps/lib/python3.7/site-packages, however after upgrading to 0.113.0 the package is no longer recognized.
What is the appropriate method of installing this package?
