Thanks for the correction. The X-10 home site pushes Insteon so I thought they were the same mfg. I guess I should try some Insteon products, I have had a few really irritating issues with X-10. One house I had to put filters on all the LV lighting to get the X-10 to respond reliably, plus install an expensive coupler/repeater. Now the customer informs me that the dimming controller I installed for the wall sconces is turning on the pool light, which is on a manual X-10 switch mounted out at the pool equipment. The Unit and house codes are different from the ones on the dimming setup. Don't know where to start on that one.
