I never implemented something like this but I did implement something similar with other uses. I also asked a question here for automating parts of the home based on user that entered. It can be implemented using OpenHab with the NetworkHealth binding : https://github.com/openhab/openhab/wiki/Network-Health-Binding. There is no need to issue different ...

Get a carbon monoxide detector, and block of one or more of the non-bedroom vents. This will force more of the warm air to your bedroom. You can just tape cardboard over the vent or they make magnetic vent blockers that are pretty cheap. I believe that you will be able to use a modern thermostat. The wiring may be confusing but if you read the thermostat ...

One red wire on your dimmer should be connected to the supply from the wall live The other red should be connected to the load the one that switches the lamp on off Black should be connected to your neutral The Green should be connected to your bare conductors or earth (ground) As mentioned previously you should have as physically minimal copper exposed ...

There are numerous timer switches that replace a conventional switch in a wall box. For example, this is a seven day timer from Honeywell The wiring for simple timers is pretty straightforward. Usually you simply replace the existing switch and wire the new switch the same way. Often you need to add a neutral wire to the switch, and most recently wired ...

There are certainly lots of systems which are basically just the controls and the hub which manages them. In some cases the hub has its own computer and software, in others (cheaper) it's just an interface that connects to a computer you supply; the programming info for those is generally available if you want to write your own software rather than using ...

The tone of your post scares me a little. Meaning if you are working in this box and cannot even identify the neutral, and are asking if one of the blacks is it, you should really get some experience or read up on basic home wiring before you start pulling things apart. Bottom line is, the bundle of spliced whites in the bak of the box is your neutral.

Doorbells generally run on 16-20 volts AC power. You can detect events using a microcontroller as seen here: http://electronics.stackexchange.com/questions/96136/how-to-sense-24v-ac-thermostat-with-a-5v-microcontroller Some computers (Intel Edison, Raspberry Pi) both run linux and have GPIO inputs; otherwise you'll have to rig up a microcontroller and ...

RCA audio cables are normally coaxial in construction, and are fine out to 50 feet or more, normally. I've run 100+ feet when needed for auditorium A/V setups. While there are fancier ways to go long distances, with modern equipment and cables there's little need for them in most cases. Most coaxial cable is not particularly suited to use as "output, ...

You can purchase and utilize a common DPDT type relay (Double Pole / Double Throw) to create a cross over switch. It is pretty easy to understand from the following relay diagram: You connect one circuit to the two NC (normally closed) terminals of the relay. The other circuit connects to the two COM (common) terminals. Then you add two additional wires ...

You could also consider replacing the switch with a motion-controlled/manual switch combo. Walk in the room and it turns on automatically. Turn it off manually when you go to bed. Bonus lower energy bill if you are forgetful like me.

I did exactly that some years ago, replacing the light switch with an X10 remotely controllable switch, and hang the remote on the wall at the other end of the room. However, that approach will NOT work with LED bulbs, due to the way it powers itself, and may not work safely with fluorescents. (X10 is the low-budget brand which introduced carrier-current ...

They've done the exact modification that you're proposing (placing it next to the door, rather than in the door) at my place of work. What you're looking for is called an 'electronic strike'. You cut out the area around the existing strike plate, and wire in the electronic strike. You'll need to feed it power, and a signal from whatever you have to ...

You moved the Green to C on one end but the picture with the transformer in the top left shows Green still on G there it should be on C. The picture below you would pull the green wire off of Green at both the stat and furnace and move it to C/Common, then you jumper Yellow to Green at the furnace.

Testor 101 answered, since there is no cooling unit use the cooling wire as C and leave the Y terminal on the thermostat empty.

SHORT ANSWER You can't convert the WeMo switch to replace a three way. You can add it to a three way circuit to turn lights on and off if and only if the three ways were first set to leave the light on. When you turn off the WeMo (at home or remotely), the lights will go off. When you turn on the WeMo (at home or remotely) the lights will go on. But, if the ...
