Compatibility notes
- Belkin lists the Smart Light Switch 3-Way WLS0503 as Thread-based (not affected by the shutdown) and WLS0403 / WLS040 as HomeKit-compatible Wi-Fi switches; the community radios (Thread, Wi-Fi, Bluetooth-for-setup) match that mix.
- Belkin ended Wemo cloud/app support on 2026-01-31; devices already configured in Apple Home keep working locally, but new setup/reconfiguration is no longer supported (Belkin article, updated January 2026).
- Firmware versions reported by community devices: 1.0.2, 1.1, 2.0.11451, 2.0.11563.
- Reported by HomeKit users in the HomeDevices community catalog (1 record, US); not on Apple's accessory page.
- Category from the HomeKit category reported by the record.
