Our #1 alarm started to sound off randomly the other day. Neighbours not happy. Its harvest time and we live rurally. I was on the phone to Smart (non) assistance for 2 hours, but they couldn't help apart from advising to switch off internal motion sensor, but didn't know where to find it in the menus......
Took the car round the block with air con max, windows all fully open and switching between outside air & recirc air. Seems to have cured the problem, but for how long?
The motion sensors detect an awful lot inside, in the recent very heavy storm a small leak developed in the roof near the windscreen/rear view mirror(since fixed) and water droplets set off the alarm at 4 am and 5am.
