The day after my system was installed I noticed the display said my side door was open when it was not open. The technician was easy to contact and came back to fix this. Then the next day I attempted to set my alarm and head out for work. When I opened my front door to leave my alarm immediately went off/alarmed. So I turned it off immediately. I used the app to set my alarm after I left my home. I called the technical support number and the person I talked to was able to figure it out fairly quickly so that my system works perfectly now.
