Smart Home Updates to STR

[Derek Brickley]

I am currently debating whether smart home updates will increase the attractiveness of a beachfront STR. This article by Stayfi includes a few recommendations for STRs, but is a little outdated. Here are some of the major categories covered in this article:

Best Smart Home Tech For Vacation Rentals
Noise Monitoring
Smart Locks (Keyless Entry)
Smart Thermostat
Home Security
Digital House Guide

What smart tech is a must-have for STRs, what is an add-on bonus, and what should just be forgotten altogether?

Thank you in advance!
