Bond all the way. 

We use Bond to control our gas fireplace. We have a button on a keypad with a triple tap for on and single tap for off. You can search the forums and find several threads on this. Makes and models included.
Pretty sure ours weren’t in the database, but we just “learned” them.

Go Bond all the way now, RF kits available, devices are on sale now for $50 and driver is $150, seamless integration to C4!

I thought I would put a plug in for FrameMyTV. If you are looking to have your TVs framed, they are a great option. It was an easy ordering and instal process. We have the Samsung Frame TVs and couldn’t be happier with the fit and finish. I attached a few pictures. If you have questions just let me know.
Also, for the dealers on here, they do offer dealer agreements.

I just have to say, I read this thread over lunch today and very much enjoyed it. It reminded me of the dogs on Funniest Home Videos chasing their tales.
I certainly can’t add any professional help, but my pic is my original system from 09’. It has grown to 24 individual audio zones and 10 individual video zones. We have 7.4 in the theater room, 5.1 in the master bedroom, 20+ cameras, lighting, remote blinds, keypads, sprinkler, etc. Lots of drivers and lots of programming. We have a CA-10 because I wanted it, though dealer said it wasn’t necessary. CA-10 is running the director and HC-800 is running zigbee, audio, IR, security interface, etc. So two “controllers” for 24 zones as I believe you are calling them. We have many areas with multiple “zones” within them and it is not a problem.
As for the OSD, we never use this, thus all the additional controllers were not needed.
 
Also, seems like a good spot to say thanks to all the pros that help out and give advice on these forums.
 

Get a Bond Bridge and the Chowmain driver.  Rock solid.

Skip the Somfy bridge, just get a Bond.  The Somfy bridge was garbage for us.  It worked about 1 out of 10 times.  Got a Bond Bridge (with Alan’s driver) and it has worked 100% of the time since.
