FAQ
Frequently asked questions
How can smart home help me save energy?
Smart home devices show what your home uses, switch appliances at the right moment and can follow cheap hours or your solar surplus. A HomeWizard P1 Meter is a good first step: a small device that plugs into the P1 port of your smart meter and sends live data to the HomeWizard Energy app.
Does it work with my smart meter?
Most modern smart meters in the Netherlands, Belgium, Luxembourg, Sweden, Finland, Denmark, Hungary, Austria and Norway have a P1 or HAN port. Details differ per country and network operator, so use the compatibility check.
Do I need solar panels?
No. The P1 Meter shows your use with or without solar panels. With panels you also see feed-in and your surplus.
What does the Plug-In Battery do?
It stores electricity from your own panels or from cheap hours and gives it back when you need it. You plug it into a normal socket. The Plug-In Battery is currently only available in the Netherlands and Belgium.
Can I use HomeWizard with Home Assistant or Homey?
Yes. HomeWizard devices have a local API, and both systems have an integration.
