Reddit mentions of Lutron Maestro IR Dimmer Switch for Incandescent and Halogen Bulbs, Single-Pole, with IR Remote Control and Wallplate, MIR-600THW-WH, White

Looks great OP! I wish I had the space for a home theater. I've been getting myself involved in some DIY home automation. I was wondering if you've considered automating the lights in your theater to dim when you turn on your projector. I bought a Logitech Harmony 1100 remote which can be programmed to control multiple IR devices at once. If you installed an IR controlled light dimmer switch http://www.amazon.com/gp/product/B000JJYJMM/ref=oh_details_o01_s00_i01 you could use a universal remote to to learn those IR commands and achieve this. Basically you'll set up all your devices (projector, game console/blu ray, audio receiver) to turn on with the click of one button, and then also have your IR light dimmer on a 5 second timer. Your theater devices would turn on and your lights would dim. Ready to party! I don't know how well the IR dimmer switches work to be honest, I'm supposed to receive one in the mail today. If it works well I'm going to buy more. I'll let you know.

It works on more than just TVs. I set up my house with IR light switch dimmers, and my LG G4 IR blaster works great with it.

Dammit, wish I thought of that and not wasted money on this stupid thing.

como o OP não instituiu limite de custos e, sonhando que terei esse dinheiro, certamente gostaria de:

• smart home (controle de temperatura, de som, de luz, de segurança, etc);
  
• um dimmer porreta como esse
  
• um cômodo para trabalhos manuais (marcenaria, eletrônica, etc) equipadíssimo com ferramentas e afins;
  
• todos os banheiros com essa privada e as suítes com banheira;
  
• sala de tv/jogos (com ótima e grande tv, sistema de som e os consoles);
  
• sala de trabalho bem equipada e livre de distração;
  
• uma edícula com todas as tecnologias listadas e com acessibilidade (pensando no futuro da velhice dos pais);
  
  gostei muito das sugestões do u/gustavohw (cabeamento, central-hub), do u/Caponredondo (coletor pluvial, painel solar e bunker)
  
  fora isso, a parte estética e funcional ganharia grande impacto na concepção da casa e renderia uma intensa pequisa mas nada que um bom trabalho conjunto entre profissionais de arquitetura e projetista não garantam – felizmente sou casado com uma ótima projetista!

A project that controls mains voltages is not a beginner project. Even more so when it's to be hardwired into your home wiring. Does your jurisdiction / homeowner's insurance allow you to perform rewiring or to install non-certified electrical equipment?

The farthest I'd go is to install suitable home automation equipment or IR or RF light switches, and then interface with them via your Arduino. They still must be installed in accordance with your local electrical code (which may, in fact, state that non-professional homeowners cannot perform electrical work themselves).

Well there are a few ways to go about this. It all depends on your level of expertise. Are you comfortable with electrical work? If not, it'd get messy. By wall switch do you mean a light switch or power outlet. If power outlet, there are products you can buy pretty cheaply.

If lightswitch, it means removing the fascia of the switch itself and adding an IR/RF (or whatever you like) receiver with a switch into the circuit itsef, drilling into the fascia of the switch and housing the receiver so that the sensor can receive the signal.

The simpler option is to install [One of these] (http://www.amazon.com/Lutron-MIR-600THW-WH-600-Watt-Infrared-Receiver/dp/B000JJYJMM)

Here are some.

Here's one on amazon

You'd still also need to by the wink hub to get it to work with your smartphone.

Belkin's WeMo line has a few options that work via WiFi:

• If your lamp plugs in you could use this module:

• If your lamps are connected to a wall switch you could use this:

• Another option is if your lamp is on a switch and your phone has an IR Blaster you can use this cheaper Lutron option:

  The last option is what's in my bedroom and my wife thought it was stupid at first, but it's one of the nicest things in the world not having to turn off the light and then fumble your way to bed in the dark.

I have the Lutron IR light switch. https://www.amazon.com/dp/B000JJYJMM/ref=cm_sw_r_cp_api_.YGsxbEYB1VX8
