A common use for home automation is to control groups of appliances when one appliance is turned off or goes into stand-by. A great example of this is having all your AV equipment turn On when the TV is turned On and turn off when it's put into standby mode. This is really easy using a Z-Wave power monitoring wall plug.
This guide shows how to use a TKB TZ88 wall plug to monitor a TV's power consumption and use a Fibaro Home Center 2 (HC2) or Home Center Lite (HCL) scene to control other appliances when the TV is On or Off.
For this example I have used:
Figure 1: Appliance Device Icons in Fibaro Home Center
This scene will use the TV's power consumption as a trigger. The TV consumes around 1W when in standby, so this scene monitors the power being reported by the TKB TZ88 and will trigger when this power is above 10W, it will then switch on the other appliances and set the table lamp to 50% brightness.
Full information about Fibaro Scenes is available in - APNT-61 - Creating Scenes in Fibaro Home Center.
Figure 2: The 'On' Scene triggers when the TV's power consumption is above 10W
Create a second scene to turn the appliances off when the TV goes into standby.
This scene is triggered when the TV's power consumption is below 10W. It is almost identical to the 'On' scene.
Figure 3: The 'Off' Scene triggers when the TV's power consumption is below 10W
As you have the TKB TZ88 measuring the TV's power, you can monitor the energy used by the TV (and even your viewing habits) by using the Fibaro Home Center's 'Energy Panel'. This reports actual consumption (W) and accumulated power consumed (KWh) in hours, days, weeks, or even months.
