“The description notes up to 10 lights - can one exceed this limitation by using rooms? If I have 4 “rooms” configured in hue bridge (in one large open area) totaling over 20 individual hue lights, can this switch control the 4 rooms as one group?”

I believe you can if using third party apps like iConnectHue. The reason for this limit though, is that automation rules/commands become unreliable when addressing too many Zigbee devices at the same time. You will have to be selective when writing up routines. Don’t try to do too much within one rule/controlling device and your system will thank you.
Sorry, there was a problem. Please try again later.I'm not sure where the 10 light limit comes from...it might be that that applies to dimmers paired directly to bulbs, without a hub (yes, the dimmer can work without a hub, although the hub adds a lot of flexibility.) The current iteration of the system offers 3 basic tools: rooms, scenes, and zones. Zones are a relatively recent addition that's supposed to be more flexible than the older room-based organization. Typically, you would still assign each lamp to a particular room, but you can also create zones that cover part or all of one or more rooms. I still don't think it's as flexible or easy to set up as it ought to be (and N.B. that zones may not be entirely bug-free and well supported, especially in third-party devices like Google assistant) but you can add any combination of lamps to a zone...no limit that I know of, other than the maximum number of devices for the hub itself. (There might be a noticeable ripple effect with a "large" number of lamps...IIRC earlier versions of the system warned about that.) You then configure the dimmer to control 1 or 2 rooms (limit of 2) or one zone, or one or more individual lamps. The latter looks pretty similar to what you are doing with zones, but the zone approach is probably preferred. You can then assign scenes to the dimmer...the ON button on the dimmer can cycle thru 5 different scenes, while the other 3 buttons do what you would expect. I hadn't used zones yet, so as a test I created a zone with 15 lamps scattered across 4 rooms and created a test scene and applied the zone and scene to one of my dimmers. Not a very thorough test, but it worked as expected for me, so I would expect that it would work for you as well.
