Twitter

The first link I gave has an example of what you send from twitter. Don't forget to include the command prefix

To see xAP traffic you need a viewer, I use a windows PC, so xFxViewer from

http://www.erspearson.com/xAP/xFx/viewer_main.htm

and to use that you need a hub, also from Edward

http://www.erspearson.com/xAP/xFx/hubs_main.htm

The hub must be running first.

There is also a xAPSnoop application which is similar but I have never used that runs directly on the Livebox

So, logged into my kevinshouse account I tweeted HAH Relay 1 on, where HAH is my command prefix. This results in a message as seen in Viewer

xap-header
{
v=12
hop=1
uid=FF00D900
class=alias
source=dbzoo.livebox.1.Twitter
}
command
{
text=Relay 1 on
}

( Note my livebox has an instance of '1')

You need to know if this is working for you before you do much else

Next you need an Alias Interpreter, and I confess I haven't used this yet

The link in the twitter section goes to the wrong version of plugboard, but I know there is an example interpreter on your livebox in /etc_ro_fs/plugboard/samples called aliasApplet.lua

But hopefully someone who knows a bit more will jump in. we can record the steps and add the full example to the wiki.

To answer your question YES if you refresh the web page.

Here is a diagram that explain how all the bit function together.

If somebody want to draw this up nicely in visio we can post it to the twitter wiki page.

I can hand draw faster than anybody could do this in a computer  :)

The plugboard is described at http://www.dbzoo.com/livebox/hah_plugboard_v2

It allows you to register an interest in a specific xAP message (or set of messages) and will then perform an action when the message is spotted on your network. As well as actions based on messages, you can setup timers which also trigger actions.

Using the plugboard is a bit more complex than using some other HAH facilities, in that you need to write some scripts in Lua (or use a script that somebody else has written). You must also enable the plugboard itself (automation/assists tab on the UI).

It's very flexible and hugely powerful. Kinda like an http://www.ifttt.com/wtf for the HAH.

Derek

Because the sample's are burnt into the firmware and can't be adjusted.  You need to copy them into /etc/plugboard before they can be executed and editted.

Brett

Plugboard needs to be activated within the web GUI so that it loads and runs the scripts

Check in above folder. 

Lawrence given you are struggling at this basic level I can give you the command however I feel you are going to struggle all the way along unless you are spoon fed the exact commands to type in.  If others are willing to help you then you may be in luck however this project is about discovery and learning for yourself, this is half the fun, the HAH isn't a turnkey system you need to do some work to enable various features.

I've looked at http://www.dbzoo.com/livebox/twitter wiki page and the EXACT command you need to enter is there in a large GREEN box that is hard to miss.  As you are having trouble reading let me reproduce it here for you.

cp /etc_ro_fs/plugboard/samples/aliasApplet.lua /etc/plugboard
/etc/init.d/xap restart plugboard

On those directories:

• /etc is Read/Write
• /etc_ro_fs as the name implied is READ-ONLY.

Brett

How are you doiing with this Lawrence?, did my write up above make sense in the end?

kevint

Lawrence. You need the aliasApplet script which is in the examples folder. 

This has been mentioned a few times in this thread and on the wiki. Suggest you reread both to understand the workings before playing too much more. You will be able to do much more with it if you take time now to undestand how it all plugs together

On the same hah web page there is a big authorise with twitter button!

It is also discussed on the wiki detailed in this post

Garry

Jim, I wasn't trying to be rude but your post says you tried to enable twitter NOT authorise it. From your post it looked as though you were enabling it before authorising the HAh. This would also explain your error message. 

If you are saying the authorisation step is not working then this will need looking at. 

I will take a look at the authorisation on my system when I get home. 

Maybe more detail in what you have tried and the exact results you got, with screenshot if poss, would help diagnose the issue without confusion Garry

Jim that wiki page regarding using a different browser for twitter authorisation hasn't been recently updated.  The section you are referring to regarding issues with IE8 was added on the 27-Jan-12.  I would find it unusual that twitter auth has suddenly broken.

Brett

As the link works ok for me

Garry

Hi Jim,

Well done on hanging in there and getting this far, it really is well worth it.

Looking at your post above, I think you may have missed typed the "cp" command, I've copied it below, from the wiki, for clarity.

cp /etc_ro_fs/plugboard/samples/aliasApplet.lua /etc/plugboard
/etc/init.d/xap restart plugboard

The first line copies the aliasApplet.lua script from the "/etc_ro_fs/plugboard/samples" folder, this part of the HAH filesystem that can't be updated, hence the "_ro_" at the start.  By placing it in the /etc/plugboard folder, and by the fact that is has "Applet.lua" at the end of it's name, it will be executed everytime the pluboard is started, usually at boot up.

The next line restarts the plugboard subsystem, saving you the hassle of a reboot.

This Alias script is key to Google as well, so once you've got this right it opens up lots of possibilities for you.

Karl

The alias script works for rf and relays only. If you want to use this for arduino stuff. Eg LED switching you will need to modify the script. 

It is fairly intuitive if you take a look at it and relatively easy to modify to suit your needs

Garry

Success!

not sure what I did wrong first time with the cp from /etc_ro_fs/plugboard/samples command, but it worked OK this time.

Once I'd remembered to restart plugboard I was able to tweet and see the message arrive in xfx viewer.

Now that I have been through the process I'm really impressed by what can be done and that all of this is provided free.

With regards to Google Calendar functionality, does the alias script mean that the HAH recognises Google Calendar events as twitter events and handles them in the same way?

(edited before seeing your response Garry)

I asked about how arduino:led funtionality could be added to the script. I've now seen there is the script section of the forum so will trawl that today.

Try modifying you /etc/plugboard/aliasApplet.lua script with the following, I've highlighted the additional code.  This hasn't been tested, and my programming skills are rubbish, but I think it will work.  Don't forget to restart the plugboard after saving the changes.

pat={
-- Add a new pattern match for the Arduino LED
    [rex.new("(led) (on|off)")]=function(m) led(m) end,
    [rex.new("(relay) ([1-4]) (on|off)")]=function(m) rfRelayCmd(m) end,
    [rex.new("(rf) ([0-9]+) (on|off)")]=function(m) rfRelayCmd(m) end,
    [rex.new("tweet (.*)")]=function(m) tweet(m) end
}

-- The Arduino LED function
function led(t)
  local addr1,state = unpack(t)
  bsc.sendState(string.format("dbzoo.livebox.Controller:%s",addr1),state)
end

function tweet(m)
  local msg = unpack(m)
  bsc.sendText("dbzoo.livebox.Twitter",msg)
end

This should enable you to send the commands "led on" or "led off", and if you're using the example from the wiki to control the LED, so the endpoint is "dbzoo.livebox.arduino:led", it should work, fingers crossed.

Thanks Garry, I did mention that I can't program ;)  Does this looks better :-

-- The Arduino LED function
function led(t)
  local addr1,state = unpack(t)
  bsc.sendState(string.format("dbzoo.livebox.arduino:%s",addr1),state)
end

OK, I edited the aliasApplet.lua script as suggested, (with the correction).

Now when I send a tweet I see this message being relayed:

xap-header
{
v=12
hop=1
uid=FF00D900
class=alias
source=dbzoo.livebox.Twitter
}
command
{
text=led on
}

But no repsonse from the led

Any ideas where the error is?

The modification you did to the alias script does not talk to xap-serial directly it will send a xAPBSC.cmd with a state event to another LUA applet acting as the BSC/Serial gateway.

The gateway applet when it receives the xAPBSC.cmd with the state will communicate to xap-serial with a Serial.Send.  This is the same applet that is responsible for opening up the serial communication channel with the correct baud etc that you would have previously got working.

Brett

Sure.  Just create an alias entry for this in the aliasApplet

pat={
    [rex.new("(relay) ([1-4]) (on|off)")]=function(m) rfRelayCmd(m) end,
    [rex.new("(rf) ([0-9]+) (on|off)")]=function(m) rfRelayCmd(m) end,
    [rex.new("tweet (.*)")]=function(m) tweet(m) end,
    ["reboot"] = function() os.execute("reboot") end
}
