A control panel allows you to switch your whole house into this mode, so as you turn one light switch on, a system of relays turns the previous room's light off.
Could also be set to limit the number of lights on to two or three, so as you walk around the house you have a tail of lights on which
can keep away the ghosts, but at the same time saves energy.
An even cleverer system would work out common pathways between rooms by monitoring your operation of their lights, and then learning to illuminate the next room you'll be walking into. This should give a single person the illusion that the whole house is lit up, but actually very little power is used.
If it knew the location of every light, it may be possible to track two or more people through the house like this, knowing which lights to turn off by acknowledging adjacent rooms.
Good idea...Baked

I've thought of this many times myself. In many office buildings, it's baked. They have all the lights on motion sensors, so that when motion is no longer detected in one room, the lights turn off. When motion is detected in the adjoining room, they turn on. |
|
| |
All you have to do for your trail effect is set a longer delay for the lights to turn off after the last motion is detected. |
|
| |
While I've not seen this in a house, the concept is identical, thus this is a redundant idea. [-] |
|
| |
I've experienced motion sensing lighting many times - usually I find it very annoying, because the lights go off while you're working at a desk. You have to run around and wave your arms to turn it back on. |
|
| |
This isn't a solution for offices or situations with lots of people. This is more of a personal thing, crucially, an alternative which doesn't mean turning lights off after a set time, which I've always been annoyed by. |
|
| |
Now wait a minute, 21. This is an idea, actually two ideas, that have nothing to do with traditional motion sensing. You are so quick! to *attempt to* debunk. |
|
| |
In one office I worked in many moons ago, I was shown round on my first day (night, actually). |
|
| |
As we walked into the darkened corridor, my new colleague shouted "Lights!", and the lights came on. |
|
| |
I did this for a week until I realised that the lights were motion sensitive. |
|
| |
I just think the motion sensor setup makes this obsolete. It solves the same problem, just as (if not more) efficiently. |
|
| |
If you set the motion sensors so that their most sensitive coverage areas overlap the areas of the room you spend the most time in (ie, for the living room, set it to cover the sofa and easy chair; for an office or study, set it to cover the desk chair) then any small motion, such as rocking slightly in your chair, will keep the lights on. |
|
| |
If you have to run around and wave your arms to turn it on, it means the sensitivity level is probably on a very low setting. That can be adjusted. I have a security light over my back door that is motion activated, and it is sensitive enough for a small house cat to activate it. |
|
| |
If you set the lights to dim slightly for a second or two before turning off, you'd have a moment's warning in which you could simply wave your hand or nod your head to keep it on. |
|
| |
My point, in short, is that there is a lot more potential use for a motion rig. Or, an infrared sensor that detects sources of body heat might be better. Either way, the posted idea just doesn't appeal to me with much more (for my preferences) convenient technology already available. |
|
| |
Note also that I didn't say it was baked or debunked, I just said the concept (turning lights on as you enter and off as you leave) is already done, and I don't think this is an improvement. Just my personal opinion, reflected by my personal vote. I'm not suggesting deletion. (although I'm getting quite tired of having to defend my right to vote however I choose. At least I have the courtesy to explain why I vote against an idea. Why can't folks just leave it at that?) |
|
| |
I've seen lights that are activated by clapping your hands, and many other similar ideas, but this really was about keeping the tactile feedback and control you have when you turn a light on, and knowing that it will stay on until you turn another one on. |
|
| |
The worst experience with automated lighting I've had was when my old school had a wall built to separate one classroom into two, forgetting to move the PIR sensor, causing many annoying problems. |
|
| |
Motion sensor combined with RFID badges and IR sensing cameras linked to a computer that keeps the light on as long as the badge is in proximity or the heat signature is on the thermal, IR image recognition so it doesn't turn on the light for the dog ... anything else we can add to overcomplicate this? |
|
| |
I think you should just ask the ghosts to turn off
the lights...and on...and off... |
|
| |
It's a good idea, but it's baked. Bill Gates' house has had this for at least 15 years. Quote from link: "Guests wear pins that upon entrance of a room automatically adjust temperature, music, and lighting based on the guest's preferences." |
|
| |
You know, I remember hearing about that somewhere, a long time ago, Knowtion. |
|
| |
One thing you can be sure of though, is that Bill Gates' house uses more electricity than it needs to. |
|
| |
From a completely energy-saving perspective, this system could be built using only analogue relays, so that no electricity at all is used while the system is idle. |
|

//One thing you can be sure of though, is that Bill Gates' house uses more electricity than it needs to//
houses don't generally "need" things except to have themselves maintained in good working condition. |
|
| |
anyways... LOFO or FOFO ? |

|
| |
What's an analogue relay? |
|
| |
//Kindly expand this idea.// |
|
| |
For the basic one-light-on only system, you could use a thyristor-like set up which would turn all the lights off, then only the current room's light back on. Obviously the more complicated system would need some kind of processor, but even then it would only need power the moment a switch is hit, as that would be the only time the lighting status would be changing. The rest of the time it could be powered down. |
|
| |
It's all quite do-able (and done a very few times). The "domotics" wiki link discusses all aspects of home living. The "lighting control system" link is specific to lighting. Controlling the curtains/blinds is also discussed in that link. |
|
| |
In all seriousness, I think the best idea is to wear a hat with a lamp on top. |
