So first observation is that the accelerometer that tells you when it's being wobbled doesn't work when it's on its back. I.e. when the red lens is facing upwards. If I remember correctly these things have a blob of mercury in them, which moves around, but they all have dead zones.
This is only a problem as this orientation was the easiest way to have it up under the saddle. I'll try a different way, perhaps by taking the red lens off, and see how it goes.
