Can I use a window contact in a climate control solution as well as in another point solution (for example security)? Or do I need to apply two window contacts to one window?
One window contact can be used in an overarching way for multiple point solutions on a Homematic IP Access Point or for various solutions in a CCU2/CCU3. Several window contacts in one window are not required.
