Hi Guys
New here so hope some one can help
I have a question but first a little of my setup and and vision.
We moved into our house around 4 years ago and from then I have started to prepare everything to get ready to automate everything, as I’m used to home automation - Installing control4 ( I helped installed the biggest C4 site in SA, it took 3 years to complete and I just loved every second of it… I hooked ) - I want my house to be a wow factor in my life but C4 are an outrages price and just not affordable to me. I have then started to play with WebIOPi on a Pi1 and all went smooth. Planned to make my own CSS file to get the look correct for me, But in the process I upgrade to Pi2’s and Pi3’s got a few of them on my network, great little hardware’s. Needless to say WebIOPi does not work correctly on the B+ boards so I ventured towards your channel and decided HA are the new route.
Now my house lights are already rewired to a 12V system and every switch in light switch and light wires in the house comes into one point. From that point I can basically do anything with them. The madness behind this were the idea of running them on the Pi GPIO, I switched to 12V as we have so many power failures in SA, all my lights and essentials like internet etc are running from a battery and solar panel, It’s great to be the only one in the neighborhood that have lights when the power are down. But now the issue…
With WebIOPi I could use two or three Pi GPIO’s to achieve my goal as I could point to another IP in the HTML. But in HA I’m not sure how to achieve this. With only 25GPIO ports on a Pi I would most likely need to use 3 Pi’s to achieve my Goal.
For my light Switches I need around 16 Inputs
For my lights I need another 16 Outputs with an extra 6 to open my Doors, Garage Doors, and gates.
And then I need another 14 Inputs to interface with the alarm system and use the existing PIR’s, Door sensors, Beams etc for motion detecting in the automation’s.
And then always You need more to expand as you go along.
If you have any suggestion or know how I can use another Pi Please let me know.
