I don’t really use this anymore, it worked for a while but became super buggy over time. I wrote a python script to handle things a bit better. https://github.com/ryanbarrett/py_dashcast

This uses a program called catt developed by Stavros Korokithakis.

I’ve set up a simple docker image that accepts commands for catt. Source: https://bitbucket.org/ryan_barrett/catt-chromecast Docker Hub: https://hub.docker.com/r/ryanbarrett/catt-chromecast

I use this to send status and monitoring sites to TVs and monitors via a Chromecast. Works pretty well. With some of the included examples you can refresh pages if required or even do a 4-up. Radar maps are always nice to have around.
