Lutron has the best customer service. Call them they will get you the right combo.

It's your choice, of course, and not what you asked about, but I won't let any of that "smart" stuff near my house.

If I can firewall it from the internet and control it over my own wifi network, that's fine. I'm OK with that. But I don't care how convenient it is, I don't want anything in my house sending any information about me or what I'm doing to some anonymous computer somewhere else that I have no control over. There's no telling where that data might end up.

Yeah, I have a smart phone, but I gave it a lobotomy. So now it works for me, the guy who bought it, instead of for Larry Page.

What problems or real risks were you concerned about and what did you do to "fix" them?

I totally agree with David on that one. I won't let any of that so-called "smart" stuff near my house either. Why? let me tell you a little story and then I let you make up your mind.

I work as an electromechanics technician, and I have a cell phone that's supplied to me by my employer, and I don't have much say over what's installed (or not) on it. I never installed any apps other than those already installed by my employer. One day a friend of mine had problems with her washing machine after a severe thunderstorm. After removing the back panel, I noticed the blown capacitors and varistor on the board, but the values were still readable. I took a picture of the board with my phone before disconnecting it, brought it home, refurbished it and installed it back in the machine and ran a load.

I then sent her an e-mail with the phone letting her know that her washing machine was fixed. I had all the components at home already, so I never googled anything about the board or the machine, or anything of that matter. For the following three weeks or so, whenever I opened my browser, checked my e-mails, I was bombarded by "deals" on washer and dryer combos, either from manufacturers, or from retail stores.

Which means that some app in the phone analyzed my photo, recognized it was from a washing machine, and sent the info to advertisement companies that I might be looking for a new washing machine.

Do I really want some anonymous computer somewhere to "know" through my doorbell or thermostat when I am home and when I am not?

What on earth is a "three pole" lamp? Do you mean a three way (one that does off-low-med-high)? There's nothing magic about a dimmer for that. Put the lamp in it's brightest configuration with the switch on the lamp and then use the dimmer as you would with any other lamp.

Per Wiki:

Three pole or three-way switches are used to control one or more lights or fixtures from multiple locations, such as the top and bottom of a flight of stairs.

I then sent her an e-mail with the phone letting her know that her washing machine was fixed.

The email about a washing machine provided the information they needed for “targeted” advertising. I don’t know what email provider you use, but Google “reads” Gmail for the purpose of advertising.

It's off topic, so I don't know how much I should get into my phone's lobotomy. But you asked, so I'll try to explain as briefly as I can, apologize in advance for the OT post, and hope that people who aren't interested will skip over this rather than getting upset with me.

The why: What I said above. I just don't want my phone sending my personal data to some computer over which I have no control, for purposes that I don't consider useful.

I also pay for every megabyte (prepaid service), and I'm cheap.

The how: The right way to start would probably have been to flash an open source ROM and not load the optional Google apps. That was more than I wanted to get into.

So, stock ROM, no Google account, sync off, GPS/data/wifi/bt off when I don't need them. Nothing in the cloud; contacts, calendar, email, and maps all on the phone. I prefer a dedicated GPS receiver, and use Osmand (Open Source Maps Android) for directions only when lost without one.

Play Store, Google Services, search, weather, voice recognition, and many other background apps and services are disabled. Firefox Mobile and websites replace some common apps. No social media. Apps are mostly open source, all sideloaded. I even have an open source Youtube app. Updates are manual on my schedule.

It's smarter than a dumbphone, but a little dumber than a normal smartphone, I don't miss most of the surgically removed features, because I use a real computer for real computer tasks, such as this one, and only use the phone as a computer when it's the only device available.

Bonuses: Despite being over 7 years old, the phone is fast. The battery typically lasts 5-8 days. Service cost is usually around $5-10 per month.

Probably most people wouldn't want a phone like mine, but it does exactly what I need and want it to do, and no more. Your mileage may vary.

Three pole or three-way switches are used to control one or more lights or fixtures from multiple locations, such as the top and bottom of a flight of stairs.

If "wiki" says that, it's inanely wrong. It's describing THREE-WAY switches. It's is incorrect to refer to those as "three pole" switches.

And you didn't say switch, you said LAMP which was what my confusion was.

Nearly every smart dimmer out there has provisions for being used in 3-way situations. Typically, one is the master that actually contains the dimmer and then the other switch position gets a remote that commands the master.

Note that this all is usually predicated on your house being new enough (or having a builder with enough foresight) to have put neutrals in all the switch boxes.
