Title: Socket Rocket & TM751 Stop Working When Cold
Post by: neil on December 09, 2005, 11:34:45 PM
 
I just received multiple Socket Rockets and
TM751 transceiver modules and find they all
stop working minutes after being installed
in a cold (~40F) garage.  Take them inside
and they work again after warming.  Has
anyone else noticed this?  Does anyone have
a recommendation for similar units that do
work when cold?

I have the exact same problem.  Mine are
going back.  I even put out for lithium
batteries on the motion sensor.

Then it is most likely the socket rocket
itself. Not liking the 40 degrees. I doudt
X10 used extended temperature parts. Many
are rated at around 40 degrees F.

All I know is mine works in my porch light
to 10 below zero.

Could be on the 10 below. Theirs maybe on
the other end of the tollerance or a cheaper
design change? I had one DOA from the box
and blew a few with a cold burn out of a 40
watt light. The few that I still have are in
the box unused.

It's the EagleEye that I'm having the
problem with.  As long as it's nice and
cozy inside the house it works.
Temperature was around 35F last night, and
outside it didn't work.

Since the motion sensors are actually
tripped by a detected temperature change
with in a certain time period. I can see why
it may not like cold weather. Some say that
bright sun also can mask movements.

My problem was that it would send the ON,
and the light would come on.  But it either
didn't send the OFF, or the signal wasn't
strong enough.  I'm using new lithium
batteries.

I also have a ActiveEye, and I think that's
a DOA out of the box.  The green light
works, the red idiot light works, but no
signals are being sent to the transceiver -
TM751 - even if I'm next to it.  The
transciever is on house code "A", and the
sensor is supposed to default to "A1", and
I haven't changed any of the settings.

I'm so frustrated with X10.

I can understand that point.

Looks like this is an old, dead thread, but I had to chime in.

I was searching the forum for information because I have a TM751 and KR19A, and THEY DON'T WORK WHEN IT'S COLD!

I have the transceiver mounted in an unheated garage.  Its sole function is to turn on/off some exterior lights as I come and go.  In mild weather, the range between the two is unimpressive, but acceptable.  As the weather cooled this winter the range shrank.  At 20 degrees, I could activate the transceiver by standing right beside it and pushing the button on the remote, however, it made a rather loud click.  At 10 degrees and below, it wouldn't work at all.

Is there something I've overlooked in getting this to work, or should I send this stuff back to X10?  It baffles me, in an era of garage door remotes that work in all weather from 150 feet, that X10 can't make a remote and transceiver that work better than this.

Thanks,

Good Evening,

I did a quick check and did not find the temperature specifications for one.  I have repaired many of the modules etc and they are not constructed with extended temperature parts.  All parts will drift with time and temperature, the lower cost items typically will drift more.  Because of the tolerances involved no two would typically behave the same.  They states that they would drift into and out of operation depending on temperature.  If you are consistently in a non room temperature environment align it in that environment, that should help a lot.  The 120 KHz would be the most suspect for drift.

Just thinking out loud,
