I've started with home automation!!
Yes, After some tests with some open source systems to control my home..
-Home assistant => https://www.home-assistant.io/
-OpenHAB => https://www.openhab.org/
-Mozilla Gateway => https://iot.mozilla.org/
Which one I've chosen? Not easy but.. OpenHAB, basically because its accessible from internet easy and without paying, home assistant it's also great but I don't feel comfortable with the payed service https://www.nabucasa.com/ while Mozilla Gateway it's not ready for a real environment.
I'm not the only one who prefer openhab, it's the most voted solution in apps comparison webpage alternativeto.=> https://alternativeto.net/software/openhab/about/
