Thank you guys fo rthe shares.
I have gone through same questions over and over reading amazon , alibaba and all these websites for practical answers to practical cases.
NEST , SmartLocks are very elegant solutions. Yet the price is pretty important ( 500 USD for one lock) .
I use following to make my host life efficient:
1-) Keysafes . Fantastic invention. It is worth just 17 USD + - ;
2-) Schlage lock ( connected lock 140 USD ) Smartthings hub ( 99 USD) + Smart App ( 15 USD) :Which comes even less than third of a SmartLock adverites solution. Very robust and sends real time notification too about when guests checkin, or door remained unlocked, ...etc.
Remain to find soluiton for smoke detector / gaz detector. NEST have sugestions at 100 USD, while regular pricing is 7 USD ( not connected). Intermediate solution would be to use roost ( 35 USD).
The good news is that there are lots of solutiosn out there. Its all about expectations, elegance, design
