Active Smart Plug II

Active Smart Plugs are clever, little devices that you add to the socket of the appliance you want to monitor (and control) before plugging it into the wall. They’re great for upping the energy IQ of your smart home.


This Smart Plug works with the Ensemble Colour, the Solo II (in Consumption mode only) and Cosy.

When used with either your Ensemble Colour or Solo II, the Active Smart Plug helps you see how much (in both kWh and ££s) your Smart Plug-connected appliances are using. It also lets you turn appliances on/off remotely.

With Cosy this Smart Plug allows you to use the Welcome Home feature, via the Cosy App, to schedule an appliance (maybe a lamp or your slow cooker), to turn on when your heating does. Good news, you can now set up your schedule independent to your heating.


View energy use. Use the Ensemble Colour display or your Solo II energynote to see how much energy (kWh) your appliances are using. Please note, this function is not available for Cosy.

Multiple Smart Plugs. Did you know that you can connect up to 6 Active Smart Plugs to your Ensemble and energynote account? For Cosy, you can schedule up to 5 Smart Plug-connected products to come on with your heating.

Keep track of energy costs. Track your appliances’ electricity consumption – see which are the hungriest (and most costly) of all. Please note, this function is not available for Cosy.

Energy control on the go. Active Smart Plugs let you see and control your home appliances – wherever you are in the world. Solo II and Ensemble users can do this via energynote and Cosy users via the Cosy app – either on mobile, tablet or PC.

Create smart schedules. Use your energynote app to schedule what times you want your Smart Plug-connected devices to come on, or turn off, during the day. With Cosy you can use the Welcome Home feature to schedule which appliances you want to switch on when your heating does or set up independent schedules for your plugs.

  • for fridges and freezers we recommend using the Passive Smart Plug II (it stops you from accidentally turning off key appliances) instead.
