Forget_me_not : My Smart Home Post#3 Week-2 Enocean Sensors and openHAB

Table of Contents


I have shared my progress of week-1 of Forget Me Not Design Challenge on my previous blog Post Forget_me_not: My Smart Home Post #2 Week-1 Getting Started....,


I am very excited, as I have received Enocean-Pi and sensors on starting of this week.. and Android application is now possible because I have bought new Android cellphone that supports openHAB android app .image


today, I am going to share my experience with Enocean sensors and setting up openHAB server for home network.

I have done with installing FHEM on my Pi by help of post http://www.element14.com/community/roadTestReviews/1795...thanks to for finding sensor’s ID.

I have all my sensors working out of the box .. PTM210 switch works fine, But temperature sensor and reed contact sensor not working properly.. Once it works and then stops working after say half hour again they work once or twice but then stops working.

sensor starts working properly after keeping them in normal room light for a two days.


here is My Initial thoughts on Enocean Sensors..


PTM210: in this Push button sensor there are two switch A and B both works fine, but I don’t know why Enocean provided only one rocker.

Here is video of my working PTM210 Push button sensor...


STM320 : Reed Contact switch works just fine and I am trying to hack this for allow to work it with other circuit.

STM330 : Temperature sensor also works but temperature is not accurate and I am working on this. on FHEM it shows D0,D1,D2,D3 digital signal and

Sensor 1, Sensor2, Sensor3 analog signals. If I will be able to use this signals without any firmware changes on STM330 it will be great and I am exploring this possibility.

Now I am ready to make some changes to sensors to work them for my application, Here user manuals of sensors from Enocean will be help me a lot.

Mean while good news is, I have received CadSoft EAGLE Pro 7 Processional license and I will be able to design my custom hardware PCB soon.image


Currently, I am trying to set up openHAB for my home network.


As I have excellent internet connectivity at my work place which is educational institute with more than 500 employee and more than 3000 students. So here is all different network topology and heavy security on network traffic compared to Home where this system going to be used. So I will not going to waste my time on this network for setup my application.


At my home I do not have broadband connectivity as like many/most of other Indiansimage, So I have decided to setup home network and remote URL using my old android cellphone with fair internet connectivity at home and I will be using that as WiFi router.


So costly WiFi router is use less for me and I am using my old cellphone as WiFI hotspot, As now I have new Android cellphone which support openHAB app, and my old phone is now helps me for that. I will be using port forwarding android application for access openHAB server running on Raspberry-Pi remotely.image


So far I am not able to connect Raspberry-Pi with hotspot running on My Old Android cell phone because my Raspberry-Pi facing power supply problem with USB WiFi adapter, So I am waiting for External Raspberry-Pi power supply ordered from element14 to be delivered shortly.

Once I will be able to setup these network, i will be happy to sharing “how to guide” here.


Mean while, Here are the Steps for creating Home WiFi Network without router (openHAB running on my Windows laptop)


  • Start Hotspot from your android phone (settings ---> Wireless and Network Setting ---> Tethering and Portable hotspots ----> Portable WiFi HotSpot -- > check)
  • Currently, I am not using any security but you can set it by (settings ---> Wireless and Network Setting ---> Tethering and Portable hotspots ----> Portable WiFi HotSpot setting-- > configure wifi hot spot ---> security ---> set password )
  • Now you will be able to see this hotspot on your windows network and sharing options, name for my hotspot is “my router”.
  • Connect to your hotspot and set it as home network.
  • On command prompt fire “ipconfig” command to know IP address assigned to your PC/laptop.In my case it is “192.168.43.8” it is your localhost now for openHAB server.
  • Run start.bat from openHAB installation folder.
  • Now setup done image connect any laptop/tablet/cellphone to this hotspot you will be able to access openHAB server running on Windows using this url http://192.168.43.8:8080/openhab.app?sitemap=demo

I’ll be update with  steps for working with openHAB server on Raspberry-Pi rather than windows, as soon as I will have Raspberry-Pi external power supply and good quality  Wi-Fi USB adapter for Raspberry-Pi from element14.


This is all about home network, for running openHAB server remotely I am still setting up remote URL using free domain name as sub domain name of such website services and exploring port forwarding for achieve fair security.

 

For my blog photos and videos, I don’t have high resolution camera image but I will shortly buy the same for my upcoming blogs image.

My way of leaning the things is very much scattered so these blog posts my not be very informative but I will try to improve on this.

Also I am working Hard to setup openHAB application according to my project needs....
