running make gives me following error

Following error after make:

fatal: [myserver]: FAILED! => {"changed": false, "msg": "AnsibleUndefinedVariable: 'homeassistant_api_key' is undefined"}

Besides, before getting this far, I had to install python or else id fail with:

fatal: [myserver]: FAILED! => {"changed": false, "module_stderr": "Shared connection to al.kas.lan closed.\r\n", "module_stdout": "/bin/sh: 1: /usr/bin/python: not found\r\n", "msg": "MODULE FAILURE", "rc": 127}

So maybe adding to the requirements something about python? Or just add it to your playbook? :)

Final question, how does the "Nas Store" entry work in the "myserver" file work? What do I add there?
