The Livebox being such a device. Due to the way in which Twitter works, you are not able to enter the same tweet twice. To work around this, the xap-twitter daemon will DELETE the tweet once it has processed it. text/html 2012-01-26T22:34:04+00:00 karl http://www.dbzoo.com/livebox/development?rev=1327617244&do=diff To extend the functionality of the inventel box you need more software. This will require a MIPS cross compiler that can be executed on an external Development Linux server. All linux development was done using Ubuntu 8.10 running inside VMWARE. This is the toolchain that I have been using to perform all my development, including on the Home Automation Hub. It's based upon the Inventel toolchain with a few additional libraries thrown in for good measure. text/html 2012-01-26T21:59:30+00:00 kevint http://www.dbzoo.com/livebox/hah_plugboard_v2?rev=1327615170&do=diff Whilst developing the HAH project I noticed there was an architectural component that would simplify the interactions between xAP compliant devices and daemons. I call this the plug-board. Consider the following use cases: * Send a twitter message when the power being monitored with currentcost goes above 2kW * If the temperature drops below 10C turn on a heater turning it off again when it reaches 12C * When a currentcost/temperature event is seen, log it to pachube * If Input 1 go… text/html 2012-01-25T20:01:57+00:00 kevint http://www.dbzoo.com/livebox/pachube?rev=1327521717&do=diff So that the data being collected by the Livebox can be graphed, shared or used to trigger other real world events we use pachube - which people in the know pronounce 'pach-bay', but sound much cooler as 'pa-chu-be'. The xap-pachube daemon has been designed to feed any xAP event that appears on the bus to pachube. This means the Livebox hardware plus any other xAP compliant software/device that you may have running elsewhere on your network. text/html 2012-01-05T15:48:03+00:00 brett http://www.dbzoo.com/livebox/xapflash?rev=1325778483&do=diff Introduction The xAPFlash application, written by Kevin Hawkins et al, is a GUI front-end that allows you to control xAP compliant devices. As the name suggests this is a FLASH based application targeted primarily at the O2 Joggler by OpenPeak. However, as this is in Flash it will run on many other supported platforms. text/html 2012-01-01T19:19:14+00:00 brett http://www.dbzoo.com/livebox/livebox?rev=1325445554&do=diff I bought an Orange_Livebox off of eBay for the purpose of learning how to put together an embedded operating system. For the money that I paid I've had countless hours of enjoyable Livebox hacking. In the spiriting of giving, I've compiled my notes. Some work is original; some is derived from other resources on the internet. text/html 2012-01-01T18:22:24+00:00 brett http://www.dbzoo.com/livebox/hah_hahnode?rev=1325442144&do=diff JeeNodes are RF enabled AVR328P boards using the same development tools as the Arduino. We love the JeeLabs weblog, jcw inspires us. As JeeNodes are RF based, they make a great way to RF enable a variety of functions. Importantly, the JeeNodes support reliable bi-directional RF comms, so we can both send commands to the JeeNode and receive information from it. text/html 2011-12-31T19:31:30+00:00 brett http://www.dbzoo.com/livebox/hah_i2c?rev=1325359890&do=diff The I2C bus can be used to extend the number of controllable devices that the HAH can access. Using the PCF8574 chip (PPE) an additional 8 I/O pins are available. Times this by up to 16 chips on the I2C bus and you have at your disposal 128 I/O channels; all accessible using the xAP protocol. The HAH PCB exposes the I2C bus on a set of four pins. See the image below for the pinout detail.
