Home Automation - remotely controlling lights from HA server via ssh

In order to control lights are years I'm using Heyu and HA-Bridge, running on a server.

Originally (and possible it will return there) was hosted by Opus, my server.

It is quite  a while now is running over a Raspberry Pi.
This article is about how to control X10 via Heyu from another computer in the network (hint, the network is not exposed to the outside)
