The idea is to use a raspberry pi as a gateway for a rf24 arduino network that automate and monitor my house. I use code form http://www.mysensors.org for the ardunio network. This repository contains the code needed to collect, store, view and mange the ardunio network. From the start I hade the intention was to build the control ui arround the gateway. Today I moved away from that idea and will use Openhab for as frontend. I started to code some to support Domoticz but will not continue doing that since that API provided Domoticz is not good as of today.
Note this code is far from finished, it work to some extent but missing features and is under development during the few hour I have to spare. All python coders try not to cry your eys out, it's the first time I try to do something in python.
Note this is far from a next-next-finished installation. You must be able to code and get around a linux system
In the future I will add config examples for openhab.
over here you have the screenshoots
- Beer - I like beer and a few were consumed...
- Python – haven’t written a line of code before in Python. Choose python because I can learn something and the first idea was to integrate a module in to tatologger. I use tatologger for graphing my ground heat pump, sorry it's in swedish but google translate will help you out.
- Tornado – was looking for something threaded that I could easily push info to and from. It's a threaded webserver written in python
This can be done much smolder but that’s for the futher. On the Raspberry Pi install the standard Raspbain – wheezy release
Clone the program from github:
git clone https://github.com/wbcode/ham.git
Install the python tornado, serial packages, and some others that I don't remember:
sudo apt-get install python-tornado python-serial python-requests python-rrdtool
Get all the files from github and configure the config file and put it all in one directory. Then run the gateway program.
sudo python Gateway.py
[config]

This can be done in two ways. Either you use build a rule or use the http binding. I have found the http binding a bit buggy.
This is configured in the rule file in openhab
rule "Set RGB value"
when
Item RGB_FV_Mancave changed
then
//you need to send com?oh=<item-name-in-openhab>&type=<item-type-in-openhab>&state=<the state you want ro send.>
sendHttpGetRequest("http://10.10.11.126:8000/com?oh=RGB_FV_Mancave&type=ColorItem&state="+ RGB_FV_Mancave.state)
end
This is configured in the item file in openhab, All should be on one row.
Switch Relay1_FV_Mancave "Relay 1" (Relays, FV_Mancave) { http=">[ON:GET:http://10.10.11.126:8000/com?oh=Relay1_FV_Mancave&type=SwitchItem&state=%2$s] >[OFF:GET:http://10.10.11.126:8000/com?oh=Relay1_FV_Mancave&type=SwitchItem&state=%2$s]" }
Same as above but with line break to make it easier to read.
Switch Relay1_FV_Mancave "Relay 1" (Relays, FV_Mancave)
{ http=">[ON:GET:http://10.10.11.126:8000/com?oh=Relay1_FV_Mancave&type=SwitchItem&state=%2$s]
>[OFF:GET:http://10.10.11.126:8000/com?oh=Relay1_FV_Mancave&type=SwitchItem&state=%2$s]" }
In item file
Switch Gateway_reload_config "Reload Gateway config"
In rule file
rule "Reload Gateway Config"
when
Item Gateway_reload_config changed
then
if (Gateway_reload_config.state == ON) {
sendHttpGetRequest("http://10.10.11.126:8000/com?op=reloadconfig")
Thread::sleep(5000)
Gateway_reload_config.state = OFF
}
end
