Pick the Kasa KP115 if you live in Alexa, Google Home or SmartThings and want to see what an appliance draws. All three connect through your Kasa account, and Home Assistant's official TP-Link integration runs it over your local network. Energy use, live and historical, shows in the Kasa app. It's a slim US 2.4 GHz Wi-Fi plug rated 15 A / 1800 W, with no hub. Apple Home and Matter aren't on TP-Link's list; the KP125M is the Matter version.
