Open Source Home Automation (Raspberry)
-
Maybe I'll leave the topic a bit, because I don't use raspberry myself but a linux server for my 'brain' so I don't have any problem with 'slowness'.
I tried out openhab and actually likes it now, it is a bit ass to start up the configuration but then you learn it you'll easy put in new stuff. I might do a tutorial later on..But right now I'm looking at the communication between mysensors and openhab and yes I know there is one script written but I was thinking of making a new gateway software for the arduino.
using mqtt protocol that is supported in openhab, and has a arduino library http://knolleary.net/arduino-client-for-mqtt/ ( https://github.com/knolleary/pubsubclient )an alternative to mqtt is to write something completely new using tcp binding or so, but I think its inventing the wheel all over again.
@Damme I use a standard Ethernet gateway for mysensors and convert the mysensors messages using a quite simple Perl script running on my server (also not using RPI, so who cares about performance ;-) ).
This script automatically publishes and subscribes to the mosquito MQTT broker, also running on the server. Works quite well!http://yveaux.blogspot.nl

@Yveaux do you want to share? I am still waiting for my ethernet sheild so I cant do much programming there yet but would be fun to try out the mqtt protocol.. :)
@Damme Ok, take a look at https://github.com/Yveaux/MySensors_MQTTGateway
No documentation or getting started yet, no time :-1: Sorry...http://yveaux.blogspot.nl

@hek Thanks! But I really need to start on my blog to document all the stuff I do... I'm afraid it isn't really self-documentary...
@Yveaux I made it work but with lots of changes, first I use serial and not ethernet on the arduino, and then I didnt find the AnyEvent::MQTT, I use Net:MQTT instead. So basically its not much left of your original script, but it was just for testing MQTT a bit.
I think it would direcly in arduino..

but since you're perling I can contribute... and maybe add/create the imperihome rest intetface on top... but You'll have to overcome some isdues related to the absence of UI
z-wave - Vera -> Domoticz
rfx - Domoticz <- MyDomoAtHome <- Imperihome
mysensors -> mysensors-gw -> Domoticz -

@epierre I'm afraid I don't get you...
So you're on domoticz, and you already have a gateway to mysensors?
Why do you want to switch to MQTT then? -

@Damme I did start with an arduino implementation buy as MQTT is text-based I needed quite some flash to store all the strings to convert the mysensors variable names and stuff.
This filled up my atmega328 almost completely and I got tired of all the trickery required to stay within the 32kb. I just wanted to prove and test the cooperation of my sensors and MQTT.
Then I realized the MQTT broker had to run on a 'heavier' platform anyway and decided that also my gateway could -- I see no use to stuff everything into an arduino.If you're interested I can share the arduino implementation, but I no longer see the use for it.
If your changes improved my implementation then please share them with us :+1:

@Yveaux My script is not better than yours, I kind of broke it.. :)
I had a thought that the atmega328 isn't enough, one option is to have external flash but no program code can be stoored there. The 32kb is still very limiting.
I had a thought of atmega2560, there is one model with build in ethernet and some with external, total cost ~30USD. It has 256KB flash memory.
So, yes I would be interessed in yout arduino code.. I might be able to slim the program down.. :) -
Hello
go Jeedom
the project progresses faster
and I motivated to make a plugin for MySensors
there will be more people motivate
faster plugin advance -

@Damme My code does only implement a MQTT client, not the broker. But if you still want it, chat me your email and I'll send it to you.

@bjornhallberg @Damme even domoticz guy are pushing people to use something better than raspberry... for a little more you have a cubieboard2 which has 1Go RAM and 2 cores @ 2011 bogomips... For z-wave OpenHab is still the best choice...
z-wave - Vera -> Domoticz
rfx - Domoticz <- MyDomoAtHome <- Imperihome
mysensors -> mysensors-gw -> Domoticz -

@epierre Yes there are a lot better options out there, but I'm not going to buy a new platform just so I can run JAVA ;-) Nothing in this price range is going to be fast enough for that I suspect. Faster, sure, but not fast as in virtually instantaneous.
I actually tried openhab2 branch on the RPi just a few minutes ago. Slow Sunday, I know. Don't know if it has been optimized yet as promised but it took about 4 minutes to start. And then it used up 25% of available RAM right out of the box, running the demo config. Would be interesting to see how fast it boots on a cubieboard2 or similar. Even if it could get it down to a minute it would be a minute too much imo. Perhaps it will run fine after it's been loaded, but those loading times were enough to deter me. I mean, in 4 minutes your house could get burgled several times over ;-) I just don't see what openhab has to offer that is worth all that.
The reason I got a RPi was the camera module. And the extremely wide support for the platform. I swore I would never touch an ARM platform again after my first Android phone and my Synology NAS but I guess the price (and camera) got the better of me. I also don't have any z-wave devices.
On a side note, I've ordered another Arduino Uno Ethernet Shield to complete the bridge to the MQTT broker. I will just have to find some automation software that will run fine on the Pi.

@bjornhallberg on my cubie (paid $50 with a box), I have imperihome gateway, mysensors gateway, jeedom, domoticz and openhab running... load: 0,6 more than 200 Mo ram available even with kernel cache...
remember that the pi has no FPU... BogoMIPS : 464.48 ...

Ok, ordered myself a cubieboard2 to have something to compare with the RPi.

@hek if you want to stay on a debian (as raspi), you can try from the SD this one: http://www.cubieforums.com/index.php/topic,1275.0.html
Kernel is quite new (not the official 3.4.75 but a 3.4.98 with temp sensor and watchdog), it is minimal so if you compile you'll add to add packages that are not present by default.
I moved because I aded dynamic linking to lua to acess sqlite3 from scripts, but it was reverted because of NAS users having compilation issues... compiling omoticz on raspi took more than 1 hour... on cubie a lot less !
Even better is the odroid, but it is yet another class (quad core, 4GB DDR3, Ekynos SoC of the samsung S3). More like an AMM counter ;-)
