Smart plugs
A smart plug sits between a lamp, fan, or space heater and the wall outlet, letting it be turned on or off by voice or app instead of reaching behind furniture. Cost: typically $10-$25 per plug. Best for: reducing bending and reaching for frequently used items.
Smart locks
A smart lock replaces or attaches to an existing deadbolt, allowing entry by code, app, or fingerprint instead of a physical key — and lets a family member remotely unlock the door for a paramedic during an emergency. Cost: typically $100-$250 installed. Best for: removing key-fumbling at the door and enabling remote emergency access.
Smart thermostats
A smart thermostat learns or follows a schedule and can be adjusted remotely — useful for family members to confirm the heat or AC is working properly, especially during extreme weather when temperature regulation becomes a real safety issue for older adults. Cost: typically $130-$250 installed. Best for: remote peace-of-mind monitoring during heat waves or cold snaps.
Which is worth doing first
If choosing just one: a smart lock offers the most safety value (emergency access), while a smart plug offers the easiest, cheapest starting point with zero installation complexity.
- Do these all need the same app?
- Not necessarily — many work with Amazon Alexa or Google Home as a shared control point even if made by different brands, which simplifies day-to-day use.
- Is professional installation required?
- Smart plugs: no. Smart locks and thermostats: most are designed for DIY installation in under 30 minutes, though an electrician or locksmith can help if preferred.
