Users / MK802 - cheaper and faster than Raspberry Pi
« on: October 25, 2012, 10:24:25 am »
This is just a short FYI for those that missed this.

There is an awesome comparison between Raspberry Pi and MK802 on youtube [1], and MK802 is priced 40$ [2] right now, which is dirt cheap, and even better it is readily available, there is no waiting like for Raspberry Pi in most of the world.

Also there seams that new and more powerful mk808[3] are also available, but I'm not sure if it is also 100% linux compatible like mk802.

These small devices run android and linux so they would make excellent linuxmce

Users / Great comparison of small wireless keyboards for LinuxMCE
« on: October 25, 2012, 09:24:12 am »
http://www.squidoo.com/rii-ipazzport-favi-mini-wireless-keyboard

Awesome comparison of multiple wireless keyboards, look some of them have gyroscope and work over 100ft so could be used as replacement for dead Fiire remote.

Does anybody have some hands-on experience with these keyboards?

Users / Ubiquiti mFi - your thoughts about these devices?
« on: July 11, 2012, 09:26:43 am »
Ubiquiti has jumper in HA and sensoring market with their new mFi line of devices [1], there are very lively discussions on their forum, most of them are very positive but some are also negative [2].

From what I have seen they are using wifi to replace zigbee and zwave, and that could drive prices down quite a bit...
I'm not sure how open/closed these devices are, and if it is even possible to integrate them with LinuxMCE (or any other system) but if it is possible then this will make a great addition to LinuxMCE hardware playground.

Hari what do you think, do these devices bring anything interesting to LinuxMCE project?

Wiki / WIKI users spam spam spam
« on: May 10, 2012, 10:17:03 am »
I would like to help and add few more security features and harden WIKI against spam. Who is main admin responsible for WIKI?

Just check this out: http://wiki.linuxmce.org/index.php/Special:Log/newusers - these are 95% spammers.

Users / [security] z-wave replay attack
« on: May 22, 2011, 06:08:20 pm »
Hi guys,
was giving LinuxMCE talk on annual Croatian Linux Users Conference and was asked one z-wave security related question: How secure is Z-Wave and could if it is not encrypted is is possible to carry out an replay attack?

AFAIK current generation of z-wave devices doesn't encrypt data, and security model is similar to bluetooth - key exchange happens during device pairing or joining new devices to existing network, right? From what I have seen, soon new generation of z-wave chips will have encryption out of the box.

So if z-wave traffic is not encrypted is there any other security and protection mechanism in place to prevent z-wave replay attacks or not?

Is it possible and how would somebody who is malicious carry out an z-wave replay attack? Is it enough to watch the z-wave traffic and spot when some command is sent, record it any replay it when ever you wish?

That way somebody could take over control over any devices you have that use z-wave...

Thank you in advance for your replies.

Users / Control your LCD/LED TV via LinuxMCE
« on: April 12, 2011, 10:27:38 pm »
If you are building new LinuxMCE system and you want to control your TV there are few ways to do so.

Every tv can be controlled via IR remotes and devices like GlobalCache iTach IP2IR or GC-100.

Also LCD/LED tv can be controlled via serial rs232 and hdmi port. HDMI way is tricky and expensive so you are left with only using IR or RS232.

If you are buying new TV I urge you to buy LG tv because they have RS232 ports and most LG tv's have cheaper models that can be unlocked to have same high end features as much more expensive models (just google for lg firmware hacks).

There is also nice WIKI page for controlling LG tv's via serial RS232:

Any comments and further suggestions are welcome.

Users / Global Cache devices in Europe?
« on: March 15, 2011, 09:31:47 pm »
Hi,
I'm looking where to buy Global Cache devices in Europe. I checked their official distributor list:
http://www.globalcache.com/partners/distributors/international/

But these lists are often out of date and most "distributors" have stopped selling their products and don't list them anywhere on their page :(

If you have bought Global Cache devices please say where from did you order them. I would prefer EU located show because of customs.

I'm looking to buy Global Cache iTach IP2IR device which is better that GC-100 device that is usually suggested.

Thank you,
Valent.

Users / Good start (User:Heinola)
« on: February 24, 2011, 09:08:58 pm »
There are quite a few excellent wiki user pages [1] on our wiki. There are also new users who are staring to build their wiki page and they need our help.
For example Heinola [2] just started his page, everybody who is starting something needs a bit help. There are also other users who also need help to make their wiki pages shine so go out there and find them.

Also there are quite a few of you that still haven't created your wiki page, why wait? Go on and start your own.

Feel free to look at mine wiki page [3] and if you have any comments how can I make mine better, easily readable, better organized, just say so.

Cheers,
Valent.

Users / Cheap network camera
« on: January 31, 2011, 01:14:54 pm »
Hi,
I would like to setup one camera, I prefer to have UTP cable to in instead of using wifi and needs to be as cheap as possible. It will be used only in one demo not for long time use.

How about this one:
http://www.dealextreme.com/p/wifi-wireless-network-surveillance-pan-tilt-ip-camera-with-10-led-ir-night-vision-microphone-34945

If you have some that are better with same price or less expensive with same features as this one please suggest them.

Thank you in advance,
Valent.

Users / XBMC running on iPhone, iPad and Apple TV 2 (Arm cpu version)
« on: January 29, 2011, 03:37:55 pm »
This is maybe off topic but too good not to share:
http://xbmc.org/theuni/2011/01/20/you-asked-for-it-xbmc-for-appletv2-ipad-iphone4/

This is AWESOME, because small Apple TV 2 uses only 6W of power, costs only 100$ and it's tiiiiny...

Enjoy.

Users / Nice system for monitoring home energy efficiency
« on: January 14, 2011, 11:38:18 pm »
I found this nice video about really nice system for monitoring home energy efficiency:
http://www.youtube.com/watch?v=E4h93XregQc

And it is not too expensive when compared to other solutions out there. It costs 500$ with 12 current clamps that monitor 12 power circuits, for some 44 circuits it costs around 900$.

From video it looks like it works only with their web service that costs 7$/month but they say that the device has also internal web server (but not too nice one). Still if somebody wanted he/she could scrape info from that web ui.

Really impressed with this company, hope they do well.

If anybody knows of some similar products feel free to post a reply or send me a direct message.

Cheers,
Valent.

Users / Nice article comparing different home automation technologies
« on: January 09, 2011, 08:04:07 pm »
Home automation project, part IV:
http://www.arktronic.com/cms/blog-entries/2009-11-15/home-automation-project-part-iv

"I've found four software solutions for Z-Wave control that look at least a little promising: ThinkEssentials from ControlThink, HSPRO from HomeSeer, Web-Link II from HAI, and the open source LinuxMCE project. HSPRO is the first to go, as it costs a whopping $600. Hell no.
Web-Link looks pretty interesting, but apparently it can't "configure" or "program" the HAI system, which in this case would be a Z-Wave system - I'm not even sure what the difference between "configure" and "program" is in this context. It's certainly cheaper than HSPRO, but it's still around $300, and I couldn't use it to do system setup or to extend its functionality (as far as I can tell), so it's out as well.

ThinkEssentials seems to be a nice program, pretty cheap (around $50-$90), and ControlThink provides an SDK as well. Unfortunately, any program using the SDK cannot run at the same time as ThinkEssentials on the same hardware, plus the SDK has some severe limitations, both control-wise and licensing-wise. Since SDK-based apps have to be separate from ThinkEssentials, I'd pretty much end up writing my own Z-Wave control suite using their limited SDK, which I don't really want to do. ThinkEssentials is, therefore, out.

All that's left now is LinuxMCE. It is extremely powerful, with many features ranging from PVR to home automation to telecommunications. It has its own Z-Wave driver that is compatible with many PC controllers and many devices. It even has a specialized interface for Windows Mobile. Oh, and it's free and open source. The problem is, I'm not sure I'd be able to extend it easily. This software is so complex that I'd have to understand very many aspects of it before I could do anything useful to it. In addition, the documentation for the software - a wiki - is perpetually incomplete and/or out of date, something which open source projects are notorious for. So while LinuxMCE is the most promising software, I don't think I want to go with it considering its issues."

Too bad he didn't contact lmce devels :(
