X10 to Wireless signal

Threaded View
We installed a Town & Country fireplace in our home and it has its own
proprietary wall mounted control and wireless RF remote contol.  I am
looking for a way to control it with my X10 powerline system and Plato
software.  I think the wall unit has the RF receiver in it and so I
don't want to replace that.  Is there an X10 to RF device out there
that could take my powerline signals and translate them to RF? It
would probably have to be a learning system since  I can't imagine my
signals would be in its library.

Many thanks for advice!
Larry

Hi Larry,

If X10 RF is used and your system has an USB port and Plato has
scripting possibilities you can use this transmitter:

First check with an X10 remote if you are able to switch the Town &
Country wall mounted control.

Re: X10 to Wireless signal
It's not likely that the fireplace control will use the same frequency as
used by X-10. Even if it does, the RFXCom hardware is illegal for use in the
USA.

Look on the fireplace remote for an FCC ID number. Then use it to determine
the frequency at...

If the frequency is one for which there are readily available transmitter
modules...

you can buy a receiver and capture the codes using...

     http://davehouston.net/learn.htm

and then build a transmitter module (home built is legal) using...

I'm unfamiliar with Plato so I cannot help with the software end.

If you cannot find a transmitter of the right frequency, you might be able
to hack the original remote but that's not always easy.

Controlling fire with X-10 is a bad idea. Unless you have a manually
operated off device like a valve bad things could happen. Such a valve
would defeat the whole purpose of X-10 except for the wow factor.

In my experience X-10 is over 95% reliable. That is not enough to
control an open flame in my house.

But that is me. I am not comfortable with an RF remote in this
application...

All models of this brand of fireplace come with a rather sophisticated
handheld, programmable RF remote so it's probably safe to assume Town &
Country, targeting upscale homes, have done their homework as far as safety
is concerned. It's unlikely that the wall mounted receiver will accept any
codes other than those it has been designed for so there's little likelihood
that one can send any "dangerous" codes that it will act on. (Still, if we
learn the frequency and protocol, it would be a good idea to test all
possible codes as a precaution since it may act on undocumented codes
intended for installer use.)

This is not a simple ON/OFF application so an X-10 appliance module to
replace the wall unit is not applicable (and I'd be concerned about safety
for the same reasons expressed by Lewis).

RF is RF so using a different source of RF doesn't change any fundamentals.
The problem, as I outlined in my earlier post, is in learning the RF
frequency and then in capturing the individual button codes in order to
accurately reproduce them. Having looked at their web page, I suspect few
owners will be willing to hack the original remote, so it really boils down
to whether T&C uses an RF frequency for which there are readily available
off-the-shelf transmitter modules (315, 418, 433.92, 868, 915MHz) or for
which there are programmable chips (covering 300-1000MHz continuous). For
that, the FCC ID on the Maestro remote is the starting point.

Also, this is going to require programming skills which are probably beyond
simple scripting. Unless the OP has those skills, there's not much to be
gained in further discussion.

One other possibility is to check RemoteCentral.com to see if anyone has
already done any homework on this.

Re: X10 to Wireless signal
You cannot control it with X-10 but, if you can do a bit of DIY construction
and programming, you might be able to control it from your PC.

I got the Maestro remote's FCC ID number from Pacific Energy sales and
looked it up on the FCC site. It uses 303.8MHz while X-10 uses 310MHz for
its RF remotes. The Maestro schematic shows a single transistor RF
transmitter section which is easily duplicated. You can capture the codes
from pin 1 of the EM78P458 MCU using an oscilloscope or the soundcard method
I detail on my web page.

Wen Shing makes a standard 4-pin transmitter for this frequency as well as a
superregenerative receiver but I haven't seen the transmitter available from
dealers.

You can buy an older, 6-pin Wen Shing transmitter from Computronics in
Australia. They also have the receiver.

     http://www.computronics.com.au/module/txrxpair /

They'll ship air mail for very reasonable rates. It has usually taken about
8-10 days when I've used them. If they don't have the receiver, you can
easily tune the 310MHz version to receive 303.8MHz.

Larry,

I'm disturbed by this a little.  Controlling a fireplace properly
requires controls that always fail safe.  X10 is a convenience
technology, not suited to what you want to do.  My biggest fear is
that the fire would be turned on when you are on vacation or
something.  Even if the signal is in the library how could you
guarantee that spurious X10 or program bugs would not turn it on
unknowingly?
