Agree.

Personally I don't see much use in smart locks for my home, but if I did have one I imagine I'd still use a regular key and carry it with me all the time. The smart lock could still provide benefits such as allowing visiting friends to enter without key etc.

Being able to remotely control and monitor the heat and water is awesome for the vacation house, but that is only in addition to using the physical knobs. It should not increase the risk (but in practice the security in such devices are terrible and you need to be somewhat knowledgeable to even assess the risk introduced).
