CLI script to programmatically replace SSL certs on Synology NAS
# *** For DSM v7.x ***
# How to use this script:
# 1. Get your 3 PEM files ready to copy over from your local machine/update server (privkey.pem, fullchain.pem, cert.pem)
# and put into a directory (this will be $CERT_DIRECTORY).
# 2. Ensure you have a user setup on synology that has ssh access (and ssh access is setup).
# This user will need to be able to sudo as root (i.e. add this line to sudoers, <USER> is the user you create):
# <USER> ALL=(ALL) NOPASSWD: /var/services/homes/<USER>/

Home Assistant Python Script to generalize pico remotes for any non-lutron light
# Script to manage a light using standard controls from a Lutron Pico Remote
# This will translate the standard button meanings on a Pico to any light controlled
# by Home Assistant.

# Expected data packet is: { new_state: X, entity_id: entity_id, fav_brightness: [0-100] }
# new_state: REQUIRED. The pico value that triggered the event.
# entity_id: REQUIRED. The entity_id of the light to control
# fav_brightness: OPTIONAL. What brightness percentage to set when the favourite button is pressed (int 1 - 100).
