Touch sensitive lamp mystery - on almost every morning

Almost every morning when I get up I find the touch sensitive lamp on. It has three level settings; low, medium and high. I'll find the lamp on in any of those levels. And who knows if it goes on and goes through all the levels and back off. I'm trying to figure out what could be causing that. I have three cats but I don't think they have enough body mass to trigger the light. There's no heavy AC spikes during the night because the air conditioner is pretty much set to off, though I have had occasion to run it. There shouldn't be any spikes to speak of.

This is a relatively new occurrence. Maybe a month or two at the most. Do you have any ideas what to look for?

Picture and brand etc of the lamp please? try putting a 1:1 transformer between lamp and outlet, see if that helps, it will reduce spikes if there are any.

EDIT: Link removed. At least one AAC member reports virus warnings. See post #12 for a screen capture of the unit I have. END EDIT
I've removed the touch pad and grounded the touch cable directly to the metal body of the lamp. Has worked for a few years now with no issues until recently.

Actually I have several ferroresonance transformers. Quite likely will stop spikes. Thanks. Good suggestion. Hadn't thought of that. Just need to put it inside a box of some sort. (not cardboard)

The one thing in its favor is the three levels of light output. The lamp itself was never designed to do anything more than just switch ON and OFF. I put a dimmable LED lamp in the socket and it works out well. The lamp itself comes with a switch in the power cord, but that you have to step on and the lamp is beside my wife's chair. Putting that switch where she can reach it would be an inconvenient pain.

This seems to be the only LED'd lamp with this issue. And for 2 to 3 years there has ben no problems until recently.

Yeah, it could be a learning experience. Then again I could just glue the foot switch to the pole and let her squeeze it when she wants it on or off. I should mention it's a floor lamp.

Consider that theelectronic assembly inside the box is made of cheap components, subject to both temperature and aging. So things will change, including the sensitivity. If there is an internal adjustment then a correction could be possible. Otherwise, adjustment will be a lot more work.

Hi
B-JoJo-S
Do you live in close proximity to a highway/road?
Certain vehicles affect my bluetooth earing aids.
Good luck.....
Residential street. Very low traffic. More traffic in the daytime than at night, yet we've never witnessed the lamp coming on by itself. Nor has the lamp come on during the daytime.

There IS a nearby AFB but they generally don't fly at night. And given there's one rocket jockey who loves buzzing the homes with afterburners - still, never in the daytime has the light come on.

I AM considering bodging up a ferroresonance transformer in some sort of housing and seeing what happens. Initial tests (years ago) showed that an input of 119VAC resulted in a 130VAC output. Little more than 1:1 but shouldn't be a serious problem. Interesting thing I learned about FRT's is that if the voltage drops fairly significantly the output voltage still remains largely constant. To a degree that is.
