sinotrack st-906 sleep mode duration

Lummia month ago

I turned on sleep mode with 5 minutes of static location as a trigger. This worked but it never wakes up after that if I don't move. I assume there was some wake-up period, right? What is it?

I'm in the same situation with an ST-901 AL, once it's asleep it no longer wakes up either by call or SMS, only when it moves, any solution?
