The standard version of the application is completely free, while the Pro one is available for 4,90 Euros.
For a detailed comparison of both versions, please have a look at the features page of our website.
ImperiHome Pro is actually an unlocker of features present in ImperiHome standard version but not activated.
That’s why you need both installed to get pro features.
Once both installed, you can run either one or the other, they will behave the same way.
