I have this one

and would like to add another - possibly in the same or an adjacent room. They are RF controlled and I wonder whether they all use the same frequencies, so pressing the #1 (for example) button on one remote would trigger the load on both #1 devices. I read the reviews on Amazon but nobody mentioned having more than one set of three. On another web site, a buyer mentioned a european model that had assignable frequencies but apparently it is not available in the US. I could probably get this one and likely not have a conflict, but I don't like the separate on-off buttons.
Searching further, I found this information here:
Cool.

The switches are manufactured in lots of 10,000 with each using a unique frequency combination No two switches in each lot use the same frequency so multiple remotes will not interfere with each other. wrote:
