This applet allows you to SEND a command to an email account which the HAH monitors.

It works like this:
In the subject line you can specify one of the following

xap-raw
xap-short
xap-alias

These are all configured via a lookup table so feel free to make up your own commands if you wish.

Depending on what you have here the content has variant behaviour:

xap-raw - means the body must be a fully compliant xap packet.
xap-short - you can use my xap short encoding format.
xap-alias - it will send a xap payload that is conformat to that which you get from xap-twitter and xap-googlecal, so you also need the aliasApplet.lua running if you want to catch these and perform some action. To refresh you memory that xap packet will look like this http://www.dbzoo.com/livebox/hah#calendar_aliases The body of a xap-alias must only have 1 line, well only the 1st will be taken in any case.

You'll need to adjust the obvious settings for configuration of the email and pop server.

Installation:

Copy the pop3Applet.lua into the /etc/plugboard directory.
The other files must be put into the directory /etc/plugboard/pop3

That is quite important otherwise it just won't work.

The POP port is hardcoded to 110 and username/password will be cleartext. Secure MD5 (APOP) is supported via port 110 too - Plenty of online MD5 generators - http://www.miraclesalad.com/webtools/md5.php

A more secure connection would be like this - note: this is NOT SSL and GMAIL *only* accepts SSL, so this won't work with a gmail account or possibly others that only allow secure connection types. I've not tested them all, but it works for me.

local popConf = {
                   host="pop.dbzoo.com",
                   user="testing@dbzoo.com",
                   pass="MD5HASH OF PASSWORD",
                   secure=true
                } �

Example email using a SHORT message

subject: xap-short
body:
xap-header
{
class=xAPBSC.cmd
target=dbzoo.livebox.Controller:relay.1
}
output.state.1
{
id=*
state=toggle
}

Example alias command - and you must have something running to pick up this message, like the aliasApplet.lua !

subject: xap-alias
body:
relay 1 on

Not Processing E-Mails

Can't seem to get this to work. I can see that my e-mails have been opened but the script, but it doesn't action them. I know you had some problems with the encoding early on, could this still be a problem, I've included the e-mail source below, any pointers greatly appreciated.

The script does not action them.

As your subject of the email is "xap-alias" this just sends out an ALIAS xap message, you need to have YET another script running that can pick these up and interpret what to do with them.

You should see this message being emitted when the email is processed.

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

There is an alias interpreter applet sample supplied on the HAH that can get you started with how to then action this message.

If you want to turn on a relay directly and not via an alias then you would need the subject to be "xap-raw" or "xap-short" and you would need to have as the body the corresponding xAP payload.

The aliasApplet is running, I

The aliasApplet is running, I use it with GoogleCal. I can't see that xap message under dbzoo.livebox.plugboard, I'll do some more testing tomorrow, I'll also try xap-raw and xap-short.

Thanks.

Not sure why but..

I am trying to get the HAH control via e-mail. I have setup the pop3Applet in etc/plugboard/ with correct host,user,pass [I am not opting to use the secure=true bit as indicated above and I have also managed to telnet ontothe pop server okay with the same details, so that shows the login works. This is also mirrored in the debug logs for the xap-plugboard which shows the pop3Applet has been loaded and the logs show a few cycles of login to check the mails. The plugboard then stops with this inbetween the last login to the pop3 server

POP3 RESPONSE : +OK 24 896
+OK 24lua: /etc/plugboard/pop3Applet.lua:54: attempt to index field 'pheader' (a nil value)
stack traceback:
/etc/plugboard/pop3Applet.lua:54: in function 'decodeBody'
/etc/plugboard/pop3Applet.lua:89: in function </etc/plugboard/pop3Applet.lua:88>
[C]: in function 'foreach'
/etc/plugboard/pop3Applet.lua:88: in function 'callback'

/etc_ro_fs/plugboard/plugboard.lua:77: in main chunk
[C]: ?
896
POP3 REQUEST RETR 24

The plugboard then stops. It has never processed test mails as xap-short, xap-alias, and xap-raw message. I presume it's something to do with the pop3Applet.lua and init.lua that resides in the plugboard/pop3 folder but not sure what.

Any help welcomed and much appreciated

A wide variety of flavours

Email is a big, complex, thing. This is why the O'Reilly Sendmail book has 1050 pages!

I reckon that the format of the email from your provider is subtly different from the ones that were used to test the script. As a workaround, perhaps try using another email provider.

Yes, I had issues with sending mail too

But managed to get that going. It's just the receive bit. I will have a look for a different e-mail provider ta Derek
