I’ve seen another thread like this, but I thought I’d create a new one as I think I’ve identified the conditions causing the problem.
Basically, since my Garadget lost its security key and I have had to reset it, I’ve noticed that my garage door has opened without me triggering it. This was puzzling at first, as it is quite difficult to see whether Garadget triggered the door to open (it has no logs), or it was somebody activating the remote.
After experimenting rather a lot I noticed this;
I interrupt the beam manually with my hand for a single flash, then remove my hand for a single flash (so the beam reflects off the reflector again), and … click … opens the door. The software has to register that the reflection % goes below the threshold for one flash, and it actually triggers it.
The problem for me is that my garage has a skylight, and the ambient light levels change with the weather and time of day. This often means that fine tuning the threshold is almost impossible as it varies so much throughout the day. This leads to situations where the Garadget thinks the door is opening for one cycle and will trigger the door to open as I described above.
This is a major security risk for me and I will have to disable Garadget until this bug is fixed.
I notice that, unless I misunderstand how it’s working, the ‘Sensor Reads’ parameter in the settings doesn’t seem to do anything at all. I assumed that if you set it to, for example, 5 sensor reads, it will have to perform 5 sensor reads before it takes any action - this is not working. It seems to do it every single sensor read regardless.
