Definitely think something funky (technical term) is going on either with the Tesla app or its widget, leading to sporadic wakeups.
I just randomly woke up, so checked my phone next to my bed like a true Gen Z wannabe and sure enough when I checked TeslaMate it said the car was online and has been for a few seconds. Checking TeslaMate it had been asleep for several hours before that.
So either I just caught it waking up by chance, or my phone did something to wake it up. I hadn’t gone anywhere near the Tesla app, or any EV app for that matter.
