Smart home technology has matured from a hobbyist curiosity into a genuine selling point. But buyers and appraisers reward function, not flash.

Here are the upgrades worth your money, and the ones to skip.

Worth Every Dollar

• Smart thermostats: They pay for themselves through lower energy bills and are the first thing efficiency-minded buyers look for.

• Video doorbells and smart locks: Security upgrades consistently rank among the most desired features in buyer surveys.

Spend With Caution

Proprietary, app-locked ecosystems and single-purpose novelty gadgets rarely transfer value to the next owner. Favor open standards that any household can adopt without buying into one brand.

Rule of thumb: If a feature saves money, improves safety, or works across brands, it adds value. If it only impresses guests once, it is a toy.
