Thanks Alan,

I think what I'll do is spec in 2 gateways for a 6X. One as a fail safe. He does have a home network wired so if needed, I can steal one of the jacks and poe the 2nd gateway. All 4 zones are on one floor so that may do the trick.

I hear you about the multiple zones on one remote. In an earlier post, I mentioned that we had used MLX2's on one job. One remote had 2 rooms ( A master bedroom and sitting room off of the master) The customer is still having problems remembering which room he is in. Funny thing is he's not willing to spend the extra on an additional remote....lol....
