Hi guys just after a little advice. 

I live in a multi storey house, 

Has 3 floors (G/F1/F2) 

I do have young children in the house and my youngest is autistic who likes to wake up through out all sorts of hours of the night and escape artist. 

I've been looking at the contact sensors obv for the front and back doors if he manages to find the door keys to open the doors. 

Obv I will need the h100 hub but what I want to know is can I use more than 1x H100 hub in my house without any say handshake issues between them. 

Say 1 on the ground Floor and 1 one the top floor that we will have in our bedroom so if he manages to somehow find the keys and  open the front or back door or if we have any visitors of the night not only will a "alarm" noise go off downstairs but will also go off in our bedroom to alert us. 

I'm quite heavily invested in tp-link products from multiple routers,bulbs, cameras, 24 port switches 

And soon tp be adding more
