4 # Version 1.0 - 20191030
5 # Version 1.1 - 20200507 - added config file support
6 #
7 # Control a light based on sensor information
8 # Get ['dark'] from sensor ID and switch on/off light ID
9 # depending where your sensor is located you can use ['daylight']
10 #
11 # For example:
12 # $ daylight-trigger.py <bridge name> -s 50 -l 24
13 #
14 # Add the following to crontab:
15 # */5 * * * * /<path-to-your-script>/daylight-trigger.py <bridge name> -s 50 -l 24 -a dimmed
16 #
17 # Follow the steps at the Hue Developer site to get the username/token
18 # https://developers.meethue.com/develop/get-started-2/
19 #
20 # Requires:
21 #   - Python >3.6
