First thing I usually check is the battery in the tilt sensor, then reset/repair the sensor device with the opener. There's a way to do that, listed in the docs, not that difficult. I assume you tried that, but since you have a new GD008, shouldn't be an issue.
I have a couple of these (GO-CONTROL), earlier versions though. I seem to recall that only CLOSED and OPEN generated events, but CLOSING and OPENING could be polled on a refresh. I may be wrong there, but if I remember correctly I built my RM code around something similar. The details I have posted below all center around that same opener. The code is hidden in the detailed section under several related rules.
The opener is at a remote property, but I can pull some additional details on the device this evening, possibly run a couple checks, and provide more info.
