My x10 modules are from the mid 90s im not sure if they have changed.

But I have a low wattage device. When I turn its appliance x10 module off it comes right back on.
Is there a better module for a low wattage device?
Or a way to make it not auto turn back on?

Background:
From past experiences this behavior seems to be how these x10 modules worked if there was no load on them.
Example if I plug in a incandescent light into an appliance module and turn off the appliance module it turns off but if I go unplug the light from the appliance module the appliance module turns back on.

I don't want to use a dimmer module on the device because if by accident it gets dimmed it would destroy the device.

Looking around it seems I need to modify the x10 application module.
By clipping the 1N4004 diode it should then operate as I'd expect.
I may end up installing a switch to enable or disable that feature.

I also might like to install a push button switch to replace the jumper as this would give me local control of the module supposidly.

Both the X10 lamp and appliance modules have local control sensing in that vintage module.

Basically if Off. You could cycle the loads power switch and it would turn On without an X10 command. Removing the load sometimes would also trigger them On.

There where modifications on some web sites to disable the local control sensing in that age appliance module.

I see you found the modifications. You may want to cut both the diode and jumper. The diode stops the sensing current that makes low wattage things like LEDs glow when Off. The open jumper kills the Local Control triggering.

The later X10 CFL friendly appliance modules are now much more tolerant of this problem. If memory serves me. Do not have local control anymore.

What is your low wattage device?

You can try maybe a four watt night light along with your load and see if it gets better.

It is a Sprint Airave that needs rebooted often.
I had plugged two appliance modules into one another turning off the outer then the inner and it was enough time off to reboot at first but its started to turn back on at an inopportune time for it(needs just a bit more time off). I have my computer sense its network traffic and if it is quite for more than 40 seconds I reboot it.

Is this what I want if my modification doesn't work?

Yes that should be the one.
X10 didn't change the part numbers when they went to CFL friendly.
All the present modules being sold are the CFL friendly ones.
My Date Code 09K48 {week 48 of 2009} are CFL friendly.

You may want to try the mods or small light bulb first.

Just as BLH says. That's the fix.

Clipping the diode worked good.
