I’ve seen from at least one other forum post that “send on motion” is not currently supported, but is planned. When it this feature planned to be implemented?
I see it as being critical to most applications for achieving reasonable battery life, since most tracker applications typically have long periods of “no motion”. I would recommend that the existing “send interval” still be allowed, with the addition of a second interval that is used when the device is in motion. This way, you might configure an interval of 5 minutes while moving and an interval of 12 hours when not moving. I suppose that it may also be necessary to be able to set the accelerometer threshold that determines “motion”.
