Wauw, absolute amazing work you did here guys, I’m really impressed
I’m a civil engineer masterstudent from Belgium and I always found the google nest, smartthings,… systems way too expensive for what they only can do. One sensor for $40, seriously who buys that? That’s good to automate 1 light at your frontdoor that lights on when it’s dark, but if you want to do more then that it becomes insanely expensive.
I already played a bit with my arduino before stumbling on this post, I’m building my own automation, starting from my room, but i want to integrate it for my whole house
I will simply explain my idea:
1 box with: Temp + humidity + illuminance + motion sensor
Every room should eventually have 1 box, and 1 on the outside of the house (arduino material doesn’t suit for outside sensors i guess…)
This “input-boxes” can be connected to a central system that calculates all the input (at first wired: easier, later wireless)
Other inputs (not in box) are contact sensors on doors/windows,…
These inputs can trigger a lot of outputs and in this way we can create automated scenes for example:
Servo motor that can open/close 1 window per room
When does it need to open?
When the temperature is too high or the humidity is too high, and there is no one in the room.
If someone enters the room and the temperature/humidity is already better, it can close again so there’s no wind
The outside humidity sensor makes sure that the window doesn’t open when it rains
PS: automated opened window only a small gap and on 1st floor, so burglaring isn’t an issue
To open this window manually there needs to be a second button to override this scene and open/close manually
I’d like to set the hour of leaving my bed on the central system, for example: 07:45 am in the morning
The systems knows i’m not a morning person so at 07:30 the curtain slowly starts to open
This is done by a servo motor that pulls a double wire connected to the curtain top, to close it the servo turns the other way around and the curtains close
The music starts slowly on 7:30 too and by 7:45 the music is loud and the curtains are open
7:45 a buzzer start, that will only stop when my feet hit the pressure sensor on the floor next to my bed
Is it possible to do with ST_anything or am I dreaming?
I’ve read a lot about your input sensors that can communicate with smartthings, hey that’s amazing so my input side could really work in this system
But is it possible to steer my output servo’s,… too with ST? In this way ST needs to recognize my window servo/alarm clock/curtain servo/… as an output, like for example a philips hue bulb
I’m really exited about getting my project from the ground
I will exchange my arduino uno for the arduino mega and buy me the shield
Can someone tell me if I can try it with ST, or better just go dreaming along and buy me all the expensive inputs and outputs?
Thanks a lot
