Part 4: Lutron

Venturing into Lutron territory now with my Serena Shades.

1. To Install Lutron… I need to obtain certification files. This was a painful process since I only have a windows PC and had to install a few things to get this to work.
   1. Component: https://www.home-assistant.io/components/lutron_caseta/
   2. This is the first challenging part as I don’t have a python environment  nativeon my windows PC.  I also am using a Docker for the Home Assistant instance on my RPI3, which previously had a python virtual environment installed.
   3. On Windows – I installed the latest version of Python 3 (at point of this blog post it is 3.6.5 released 3/28/18)
      1. https://www.python.org/downloads/
      2. Make sure to check the “install pathways” or else it is difficult to setup the file pathway in command prompt. Without pathways clicked, command line does not know what the “python” command refers to. This is referring to the python.exe sitting in the install file.
   4. Grab latest Python Certification script.
      1. https://github.com/gurumitts/pylutron-caseta/blob/master/get_lutron_cert.py
   5. Install PIP on windows.
      1. https://dev.to/el_joft/installing-pip-on-windows
      2. This is important since it helps us install and manage software packages in Python.
   6. Run the package installer for cryptography and requests which is required for the Lutron certifications. Within command line.
      1. pip install cryptography==2.1.3 requests==2.18.4
   7. Run the Lutron certification python script. Within command line.
      1. python get_lutron_cert.py
2. Nest and Door Sensor Update tomorrow!

Oh yea… broke my foot on 5/7/18.
