I am actually impressed with this product. I am using it for my garage roller door and works great. Had concerns about it connecting to my google nest wifi as other products did not work but this had no issues. I rrally like the UI how it shows if that garage door is opened or closed and also the alerts when it has been opened or closed. I would recommend that the lead cable from the unit that connects to the motor was a bit longer and also maybe looking at creating some brackets for the sensors for roller doors as this is more for panel garage doors.
