Hi

I would like to build home automation system in which I can control the
boiler switch from the internet.

I could not find the information which pc controller should I buy.
Will this do the trick
http://www.smarthome.com/1132b.html
?

What is the differenec from this one:
http://www.smarthome.com/1135.html

Does the later connect to the PC through serial port?

Thank you

How will you interface with the Internet?

The 1132b has an RS232 interface and you can communicate with using a fairly
simple ASCII protocol. The 1132b can also emulate the 1135.

The 1135 has a TTL (Transistor-Transistor Logic) interface and you must
communicate with it at a much lower level, synchronizing your inputs with
the powerline zero crossings.

Thanks for the quick answer!

Now, can I find the 1132b in 220v version in the USA?
The 20amp/220v appilence for the boiler is available here
http://shop3.outpost.com/product/2889254?site=sr:SEARCH:MAIN_RSLT_PG

But I could not find the right contoller...


Connecting it to the Internet is just a programming issue.
If I'll know how to make a program that turns on the boiler (with the
controller), I can, for example, make a program which reads an email
and turns it on when an email arrives. Then I'll be able to turn on the
boiler with my mobile phone...
Of course there are many security issues here, but as I said, it's a
programming issue.

Thanks again
Saar

The 1132B is not available for 220V.

If you are going to use a 220V appliance module you can find European
versions of it as well as X-10 220V controllers with RS232 interfaces.

Search for "CM12" at www.laser.com to see what's available.

You can go with a single box solution that plugs into your home network
with something like this

Or check this good site ive found for some similar products for really
cheap prices

What is the difference between CM12 and 1132b beside the voltage?
Do you operate the CM12 with the same simple ASCII protocol?

Can I buy CM12 at www.laswer.com and a X10 applience
http://shop3.outpost.com/product/2889254?site=sr:SEARCH:MAIN_RSLT_PG
will they work together?

Anyway, do you think there is a better solution using RF instead of X10
??

[Dave Houston]

The CM12 will work with 3 phase systems while the 1132B will only work with
a single phase system.

The communications protocol for the CM12 is a bit more complicated but it
can be controlled via a command line interface using simple English
commands.

Aside from the plug style, I think the USA appliance module will work but
Laser (and other European dealers) also have European versions of it. Search
there using "appliance module".

There are numerous RF systems available in Europe but I'm not familiar
enough with the details to offer any advice in this area. Finding an RF
system with a PC interface may be difficult.
