advice for retro installation

I believe that was John Hillerman.

Hopefully more useful information will follow (I mean since you're "into" this stuff, Robert).

After hearing his English accent on that show a number of times I got a kick out of hearing that he's actually from Texas. :^)

Yes, quite!

Are these now controlled by wall switches?

A basic question here is whether you want your security system to talk to your home automation system. If so, you need to ID the make and model of the security panel to find out if it can be interfaced to a home automation panel. My guess, based on the old home theater system you found is that your alarm system probably is too old to communicate with an HA system. It's not hard to install a new panel, though, and there are several good manufacturers of combo HA and security panels, like HAI and Elk. It just might take a while to ID all the sensor cables coming into the panel if they weren't well labeled to begin with. You'll need a fox and hound tracer kit to map them out.

Lots of things to consider here. How are these circuits wired? Are there dimmers? Do you want to do scene lighting? Do you have a neutral pulled to each switch box?

Centralized control equipment is good, but it may be old enough to warrant replacement for both wear and compatibility reasons. You have to ask yourself how much automation you want for your hot tub. If you can afford such a pad, you may not care much about squeezing a few dollars savings a month in electrical costs with an automatic controller. You may want to equip it with sensors to determine various conditions like temperature, fill level, etc.

That's a good reason to look at wireless like Zwave or Zigbee! Running any additional control wires tends to be a lot more difficult in concrete construction than in wood frame. My personal opinion is to use hardwire wherever you can for the increased security and reliability it offers

You might be facing coupling problems with three panels. Most times these are solved with the addition of couplers and repeaters, but in rare cases they are notoriously difficult problems to solve. If I were about to build or in the planning stages, I would look hard at Zigbee as a protocol. How long are you planning to stay there?

HAI's Omnipro II would support that sort of requirement, IIRC, at least as far as lighting and IR control goes.

I would suspect that's a deal-breaker for X-10 in a big condo building. X-10 was basically designed to support 16 units per house (although you can use 256 codes if you use EVERY housecode - lots of people use multiple housecodes but the closer you are to neighbors the more likely you'll get interference).

Lots of experts here really dislike using a Wintel PC as a controller for a home automation system and I agree. Elk M1 Gold, HAI Omni Pro II and the ADI Ocelot/Leopard controllers are the ones most often recommended. They can do most of what a PC can do vis-a-vis home automation. They have advantages in reliability because of the smaller component counts and they are less complex because they don't have to carry overhead for the kinds of things an HA system will never have to do. An HAI panel will reset in seconds. There are very few PCs and OS's that can beat those times, nor run as long as a dedicated box without lockup nor run as long on backup power.

What type of bulbs are used in the fixtures? Any information on the dimmers? There are ways to dim fluorescent lamps using a number of different protocols and the new CF dimmable bulbs work with many dimmers designed for incandescent loads.

Like Leviton SnapLink Mobile App, NQLink work with Leviton Security&Automat ion Omni/Lumina familly Controller. NQLink use latest technology for connec tion and data processing, NQLink much faster on connect than other app that you ever seen.

NQLink Provide both connection Local IP and Outside IP or domain name with one account for all devices: Controller, Hi-Fi2, Music Sever, Camera. App a utomatically looking for available connection every time. if you switch you r phone between Local wifi to cellular data network, NQLink automatically s witch connection also.

NQLink can run in background and start with your phone reboot to give you o ption notification on system such as: Security Mode, Lighting changed state .,etc.
