Dealing with 2-way switches, the SwitchSmart way

Having the flexibility of turning on or off your devices from multiple points around your house can be a very versatile thing. Many houses have some form of built-in 2-way wiring that could perhaps allow you to turn on a walkway light from the entrance of the house, and then turn it off again when you approach the end of the walkway.

The diagram above shows the typical setup for a traditional 1-way and 2-way switch.

"Smart switches allow you to do away with all the traditional pre-requisites and limits."

With traditional 2-way switches there is a need to ensure the wiring is setup in a way that ensures 2-way connectivity, and also a limit on the number of switches you can have (as above, the limit is 2).

Smart switches allow you to do away with all the traditional pre-requisites and limits. This means that any switch in your house could now become a 2-way switch. Better yet, you could have a 5-way switch, for a device your whole household could have access to from each individual room.

What a traditional switch achieves through physical cables, the smart switch achieves through the use of software. We can assign one smart switch as the "master" switch, physically connected to the device being operated, and all other switches as "worker" switches, not physically connected to the device being operated.

Here's how you Switch:

One example of this could be a way to turn on the storage water heater prior to a shower. Many households place the water heater smart switch near the bathroom, this switch is a special smart switch that is rated for a high power requirement due to the nature of the water heater. In every other room, regular smart switches or wireless smart switches are used. Now, users who need to shower can turn on the water heater from the comfort of their room saving them the wasted trip to the bathroom just to get the water to start heating up.

And here's how you Switch Smart:

Better yet, we've now incorporated a time-delay so any user who turns on the master water heater switch will only do so for 10 minutes (or however long your hot steamy bath requires). After 10 minutes, the water heater switch will automatically be switched back to off conserving power and ensuring no one has to worry about forgetting to turn the water heater switch back off. Or, if you've finished your bath earlier than expected, you could also manually turn it off to save even more on your bills!
