The nagging questions that I will try to answer with my project are:
- Did I leave the curtain open or close?
- Did I leave the washing machine active or not?
- Did I leave the basement door open or close?
- What are the temps near my windows?
The Plan in picture
The Plan in detail
(1) Incorporate EnOcean temp sensor data in existing application
My current head controler system use temp DS18B20+ sensor (2) and sainsmart Solid State Relay Module for control my house water heat system.
Current application use postgresql databse for save sensor data and nodejs server for host webserver.
We need to add support for 3 new EnOcean temp sensor (6)
(2) Use Tekronix TBS1202B-EDU Oscilloscope for analyse existing network of DS18B20+ sensor
1-wire Network use an star topology with different cable length. With 7 captor we have many captor communication error. Some sensor have up to 30% of read failure
We try to reduce Reflections with some resistor with information found here http://www.maximintegrated.com/en/app-notes/index.mvp/id/148
I will try use Oscilloscope for compare 1 sensor vs my 7 sensor network and see the diffence

(3) Build new control panel
With an Raspberry Pi and Adafruit PiTFT we made control pannel with the capacity to see and control home temps and control curtain open/close
(4) Add Raspberry Pi + EnOcean Pi
Add raspberry pi to make Wireless Gateway for EnOcean product. We put in back of my tv and turn my tv in big home status panel
(5) Add 2 Push button switch module for control 3 windows curtain open close
Use 2 Switch with 4 buttons to control curtain open and close. One button by curtain and 2 device one by floor
(6) Add EnOcean temperature sensor
Add 2 or 3 EnOcean temperature sensor very near the window and display sensor data in my existing system.
Use temp of captor near the window and other temp sensor in room for automatically open or close curtain.
In summer close curtain when temp near windows is higher than room temp and open curtain when temp near window is lower than room temp for optimising air cooling. Do the opposite in winter.
(7) Make curtain open close system
With Raspberry Pi and Stepper Motors made curtain open/close system. Communicate with other Raspberry by using my wireless network.
I also try communicate with EnOcean Pi to send and receive command from my EnOcean Wireless Gateway (4). I compare advantage and disadvantage compared to normal wifi 802.11n
(8) Add EnOcean magnet contact sensor for detect door open/close
Add EnOcean magnet contact sensor and display door state in my web page
(9) Add EnOcean magnet contact sensor for detect washing machine active or not
Add EnOcean magnet contact sensor and display washing machine active or not in my web page
(10) Try OpenHAB for replacement of my current home management custom system.
(Extra) Try new Apple HomeKit with EnOcean sensor and my existing system
My existing system
