........... the other appliance unit worked for a while but now NONE of the units except the main one are working.
I am pulling out my hair trying to figure what happened. I don't recall plugging in anything that would interfere with the reception but ...well, that's why I'm posting here, to get some ideas as to how to get my X10 working again.
As a bald man... I hate to hear of anyone pulling hair out!We just had Christmas at my home... and
new plug-in devices can always put X10 at risk. Although
I feel X10 is hardier than sometimes given credit for... it is true a device that charges batteries can put a lot of noise on a power line. Many new devices can also absorb X10 PLC.
First things first... I'd map that circuit or circuits that are having the problem. Unplug everything that isn't X10 first... and if that fixes the problem plug things back in one at a time testing after each device. It could be that your problem is on another circuit and can be anywhere in the house. Checking every circuit may be needed. If you've never mapped your circuits... so you actually know what line is where and what is on it.. this would be a good time to do that.
Puck [here at the forums] wrote a GREAT thread on
How to map your circuits.
Many of us here at the forum have discovered that because mapping the circuits involves switching off breakers... it is best done when alone at home.
Be sure to remember to ask [family members] about left-in cell phone chargers in bedrooms and other places. And remember to check the garage and/or basement workshop for charging devices (like a Christmas drill).
If you find a offending device [like a new LCD TV sucking up your X10 signal]
a plug-in filter can restore order to your system.
