@madmike, whats a smart outlet and wallswitch and what does it do?
Smart switches and outlets are programmable and controllable from a smart phone, home automation syctem or or PC. The communicate via wifi.
The simple things anyone can do using a phone and or Alexa or Google Home:
- see the status of the switch (on, off or if dimmable the %dim)
- turn switches on/off using the app or with voice commands
- set schedules for them to come on /off. For example, if I forget to turn a light off, it will automatically shut off at 1AM
They are also controllable through higher end apps that can react to triggers and process scenes. A trigger might be something like sunset, sunrise, a door opening, or another switch being turned on. A scene is a sequence of events that happen at a set time, or upon a trigger.
Examples:
Simple:
Status & Control: I can see whether a light is on or off, power to my Christmas Tree lights is on or off using my phone from wherever I am.
Scheduled: I can set any switch to off or on based on time of day and day of week. My pool pump runs for 20 minutes every 4 hours and for 6 hours during discount hydro hours.
Advanced
Triggered: I can set a light to switch off 30 minutes after sunrise, set the garage and path lights to come on when I get witin 200m of the house.
Scene: I can tell Google Home to "Play Monday Night Football." It will turn on the power to my TV, turn the TV and load DAZN, dim the TV room lights and IF the sun is still up, it will close the shades.
Where the savings come in form me is as follows:
1) Timers on pool and lights. My lights all shut off at 2 hours after sunrise, 9AM and at 1AM. Some rooms (bathroom, closets) go off a few minutes after they are switched on.
2) TV/PC bleed. A small amount of power is consumed keeping computers and AV gear warm for the 23 hours a day when they are not used - I now save that.
