Sensivity selection and battery replacement

Hi, i just want to know if i cant tune the sensivity, i have a dog and i just don't want the sensor activates all time the dog goes near, and the other question is when the battery deads i can replace to a new one such Windows/Door sensor?

is a battery, not just a disposable battery

Settings of the sensitivity via the app or the WEB-UI or via HTTP

Settings on the Shelly Homepage

HTTP-Request Shelly MOTION

So it can ignore a dog, or not?
