Home Automation - fixing Ha-Bridge

Are now years I'm using a program called Ha-Bridge that basically simulate a Philips Hue hub.

The peculiarity of this program is that can be recognized by Alexa and it can control my X10 lights via Heyu. I did set up this system in the 2016, as described in the article of this blog Playing with Alexa and Echo

X10 - AM486 - disable current sensing



At the time of the top usage of X10 there was lot of technical info on the net, today ... not so easy to find them.

I have to modify an old AM486 disabling the current sensing and I didn't find much around, so digging on my old notes here and some searches, I did come up with some info that I hope can be useful to others.

Raspi calendar - HW-SW

 OK, this is my set up for a calendar display using a Raspberry Pi.

Is quite a while that I wanted to have somewhere a calendar display and was considering different solutions, then one weekend I decided to do something about.

The goal is to have somewhere (kitchen maybe) a monitor showing the Google calendars of the family.
Here some notes.
I'm assuming who is reading this article knows how to set up a Linux system, I'll not describe in details many operations.
