What device causes issues for you may not for someone else. Many had noticed led bulbs (when first started to emerge) even from same manufacturers and same age behaved differently.
Same can be said for power supplies and surge protectors.
What didn't cause a issue yesterday might start causing a issue tomorrow.
A search for noise or signal suckers will turn up many examples. I've been fairly lucky as for issues with noise and signal suckers but I do have a noise meter which quickly finds any problem device.
I have a feeling it's one of Jeff Volp's "No longer available" XTBM meters....
Which means I'm SOL on that one.
Your "you and not others" suggestion had me realize that yes, highly likely in the sense that a manufacturer gets complaints that "product X" is messing up PLC devices (X10 isn't the only one playing in that territory) so the manufacturer adds a filter or makes a change to the next "Lot" of the item they make, but it may still have the same model number on it.
So looking at the bulb, device or whatever, you can't tell whether it's the old lot that had trouble or the new one that has been fixed.
Just thinking about even X10 devices like the RR501. I have some really old ones that only do 8 house codes - 1-8 or 9-16 - whereas the new(er) ones do all 16 codes and the front switch just selects the internal appliance module between 1 or 9.
They didn't change the model number as far as I know. They're all "RR501".
