The Smallest Window, Door, Drawer Sensor ! Meross Sensor Kit

[@NeoVdV]

I have 2 of these but only can connect one at one to the hub ?!? Can't I connect 2 or more to the same hub ?? Using the MS200 with the mini hub MSH300

How exactly do you add a second/third/etc sensor to an existing Hub?

Anybody could explain me how can I make this device sound in my phone?
I receive a notification every time the door is open but it doesn't sound! What if I am sleeping?
