For the time being, one ImperiHome account can only be linked to a single WiZ Home.
ImperiHome integration can only be activated for one WiZ home at once, otherwise ImperiHome would not know which one to control. Thus, when you activate ImperiHome for a new home, it will alert you with a pop-up in the WiZ application that the existing integrations will be disabled.
The impact is equivalent to “de-activating” the toggle button next to your ImperiHome integration in the WiZ application.
