I have an MX-800 (and software). I've never used the RF capability, but I would like to control a single light switch (for the main overhead lighting) in my HT room. Right now I have a standard wall switch Caseta Lutron dimmer with the RF control and it works well with the included remote but my understanding is that it won't work with the MX-800 because it is the wrong frequency.

Assuming I could find one, is this what I am looking for?

If so, do I need the Standard or i-Series (which seems to also require some other unit).

I simply want to be able to turn on/off (and maybe dim) the lights without getting off my recliner. The Lutron remote is fine, but it's really small and more than once in the dark I've dropped it underneath the seating and besides, it would be nice to have it controlled from my MX-800. Or maybe there is another solution someone can suggest.

Thanks very much,
