What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Kasa HS300 is the default recommendation for a six-outlet smart power strip. The Spruce's hands-on writeup describes it as easy to set up, dependable within the Kasa app, and useful as a basic surge protector, while PCMag frames it as a feature-rich six-outlet smart surge protector with voice and mobile control. Per-outlet scheduling, individual energy tracking, and three always-on USB ports are the headline features mainstream reviewers keep returning to.
What reviewers liked
- Six individually controlled outlets plus three USB ports in a single chassis, repeatedly called out as better value than stacking individual smart plugs
- Verified-purchase reviewers and The Spruce's hands-on both highlight easy Kasa-app setup and reliable scheduling
- Per-outlet energy monitoring in the Kasa app, which specialist subreddits use with Home Assistant
Where it falls short
- Multiple r/homeassistant and r/Sense threads flag long-term Wi-Fi reliability and unit failures
- USB ports are always-on, so reviewers note you cannot schedule or remotely cut USB power
- No Matter support, which r/HomeKit and r/homeassistant users increasingly cite as a reason to look at newer alternatives

Specialist-community sentiment is more mixed and worth surfacing. Threads in r/homeautomation and r/smarthome praise the outlet spacing, the value relative to buying five individual smart plugs, and the local-LAN responsiveness. But r/homeassistant and r/Sense include pointed complaints about long-term Wi-Fi reliability and units that 'break down too soon,' and at least one user reports migrating away from Kasa toward Matter or Z-Wave for that reason. The USB ports being always-on, not switchable, also draws consistent criticism.
Weighing the verified-tier writeup, the medium-tier expert consensus, and the mixed but mostly positive specialist-subreddit signal, the HS300 still earns the top slot, but reviewers reading this should treat it as a known-quantity Wi-Fi product, not a future-proof Matter one.

The TP-Link Kasa Smart Wi-Fi Power Strip HS300 is a feature-rich six-outlet smart surge protector that you can control with your voice or with a mobile device.
I found these TP-Link Kasa products to be quite low-quality, unreliable, breaks down too soon. Their automation isn't reliable, resets ...
Have any of you used this with Home Assistant? Were you able to fully control and power monitor each individual device like they claim within HA?
