Dahua event listener for home-assistant (http://home-assistant.io)

1. Install following

sudo apt install libcurl4-openssl-dev libssl-dev

2. Install pycurl on home assistant env

pip3 install pycurl

Code borrowed from https://github.com/johnnyletrois/dahua-watch and made into a home-assistant component

Copy the file your custom_components folder and add your configuration. The component depends on pycurl, if that won't load, check your dependencies.

You can work with multiple camera's or NVR's For a device, the only required config item is the host, all other values default to the ones below.

• Clone or copy the root of the repository into <config dir>/custom_components/dahua_event

  If you are using Windows:
  * Download the zip file and extract the folder inside to your custom_components folder.
