Best Motion Actuated Switches AI pick
Chosen by an AI model from its trained knowledge, with its reasoning.
AI pick (line): Lutron Maestro Occupancy Sensor Switch
A reliable in-wall PIR switch that can be set to occupancy or vacancy mode, and versions are made for LED loads.
Not for: Large open offices or warehouses that need ceiling-mounted or dual-technology sensors.
AI picks by need
For Alternative in-wall Decora style
Leviton Decora Occupancy Sensor (line)
A widely stocked in-wall PIR switch family that fits standard Decora wallplates.
Not for: Restrooms or rooms with partitions where PIR alone misses occupants.
For Commercial spaces / code compliance
Wattstopper (brand)
A Legrand brand focused on commercial occupancy and vacancy sensing, including dual-technology and ceiling sensors.
Not for: A simple single-room residential retrofit.
What the AI looks for in Motion Actuated Switches
- Neutral wire
- Check whether the box has a neutral. No-neutral models have minimum-load limits. No-neutral sensors leak current through the load and can make low-wattage LEDs flicker.
- Occupancy vs vacancy mode
- Vacancy (manual-on, auto-off) is required in some spaces by energy codes such as California Title 24. An auto-on switch may not pass inspection in those spaces.
- Sensing technology
- PIR needs line of sight. Choose dual-tech (PIR plus ultrasonic or microphonic) for restrooms, stalls or obstructed rooms. PIR alone switches lights off on people who sit still or are out of view.
- Load rating and type
- Confirm the rating for LED/CFL, incandescent and motor loads separately. LED inrush and fan motors exceed some sensors' ratings.
- Coverage and timeout
- Coverage must reach the far corners. The timeout should be adjustable. Short timeouts cause nuisance off-cycles. Long ones waste the energy savings.
Brands that matter
- Lutron: Maestro in-wall sensors with good LED compatibility.
- Leviton: Broad residential and commercial sensor range.
- Wattstopper: Commercial occupancy and vacancy sensing specialist.
- Hubbell: Commercial wall and ceiling sensors.
What to avoid
- No-neutral sensors on very small LED loads without checking the minimum load.
- PIR-only sensors in restroom stalls.
- Auto-on sensors where code requires vacancy mode.
Questions
What's the difference between occupancy and vacancy sensors?
Occupancy sensors turn lights on and off automatically. Vacancy sensors need a manual press to turn on and only turn off automatically.
