Dear Community!
I’m so excited when thinking about openHAB at my home, so I decided to join the forum and ask for some guidance. As far as I can check this is “yet another hardware recommendation” thread, but I’ve got different circumstances which I’ll try to describe below.
I’m building a totally new house, this is my first one and I’m researching hard every topic. This is how I’ve got here . I have several years of experience with electronics elements (passive and active), embedded development, Linux and programming in most modern languages. I have no experience in home automation. I want to implement openHab 2 in my home. There are bare walls for the moment and I’m starting with some electricity (230V). I’ll be doing it all the way alone and this is the point where I want to ask you for help:
- I want to control light with openHAB, preferably with dimming capabilities, so when I turn it on or off it slowly fades in or out. I want to use bi-stable wall switches just like in the “old days”.
- I want to control the gate for the garage and for the entrance to my lot, preferably opened by GPS coordinates of my car, WIFI connectivity, license plate numbers analysis,
- I want to control alarm system: motion, fire and flood detection. Alarm will be based on Satel platform (Integra/Versa). I want to arm/disarm the alarm with a schedule, using RF pilots, use motion sensors to detect motion and basing on it turn off and on lights.
- I want to control shades/blinds for the windows.
- I want to control CCTV system (motion detection/recording control).
- I want to control heating system (heat pump with floor heating, separate temperature for each room, cooling system - dew point).
- I want to control outside temperature and turn on/off ground heating for the road to the garage.
There’s plenty of things on my wishlist, I know, and the budget is also a limitation, so this should be kept in mind. I would need an advice what platform should I use for openHAB hosting. Raspberry Pi does not seem to be the best choice for a complete home automation system used heavily each day. I thought of some industrial computer with Slackware Linux installed and openHAB on top of it. I will need to control things via RS-232, RS-485, KNX or Modbus and LAN. This will be needed for heat pump control, CCTV, alarm system. I don’t know what else would I need depending on other “things” I should use.
I’ve got following questions:
- Do you think that Slackware Linux on industrial computer with SSD drive would be good option for such system?
- What electronics do you suggest for controlling the things I mentioned above keeping in mind budget constraint?
- Do you think that it is a good idea to base whole home automation on an open-source system like openHAB or I should go for something like VisionBMS?
I would highly appreciate all information in this topic.
