“Via Matter” means you add it with that platform's Matter controller instead of a brand skill or app. “Unconfirmed” means we couldn't find an official source either way. How we verify.
Specs that matter for setup
- Radio: 2.4 GHz only (802.11 b/g/n), on a secured network.
- Hub: The page says no hub is required; the strip joins home Wi-Fi directly.
- Local control: Home Assistant's integration (IoT class Local Polling) connects to Kasa devices on the local network without the TP-Link cloud, and doesn't flag the KP303 as needing TP-Link cloud credentials. The Kasa app itself goes through the cloud.
- Energy monitoring: The Kasa page does not mention energy monitoring for the KP303, and Home Assistant's page does not name it among energy-monitoring models.
- Max load: TP-Link states 125 V AC, 15 A input and 1875 W maximum load in total across the strip. Three smart outlets plus two always-on USB ports (5 V, 2.4 A total).
