“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 Wi-Fi (IEEE 802.11b/g/n); the spec list shows no other radio.
- Hub: Kasa says no hub is required; it joins a 2.4 GHz Wi-Fi network directly.
- Local control: Home Assistant's integration talks to Kasa devices over the local network without the TP-Link cloud. The Kasa app itself goes through the cloud.
- Energy monitoring: Kasa's HS103 pages don't list a power meter, but we found no official spec saying it has none.
- Max load: Both Kasa pages give 1800 W general use and 15 A resistive at 120 V AC; the 15 A line carries a footnote saying it applies to the new version.
Before you buy
