Model: HS103
Compact Wi-Fi plug with Kasa-app scheduling and Away Mode; check the exact US revision and load limit.

What to know about this device before choosing a connection.
A recommendation is not recorded yet. Compare the requirements below with your home and the capabilities you need.
US product specifications: 10 A resistive / 1200 W general-use maximum. Do not substitute another HS103 revision’s 15 A rating. Match the label on the installed unit; the retained US V5.8 support-linked guide documents setup, not a broader electrical limit. Documentation reviewed October 16, 2026. Active means manufacturer listing observed; stock, independent certification and physical-device testing are not established. Home Assistant support-list membership does not approve an exact native or Matter route. Match model, region, hardware and firmware before use. Manufacturer-documented Kasa app functions: schedules, Away Mode. These are vendor-app/catalog features; their Home Assistant, Matter or other integration exposure has not been reviewed for this device. Auto-Off and a generic timer are not treated as proof of a countdown timer.
