Stop walking back for the lamp
If the glow is still leaking under the bedroom door, you need a plug — not a new ecosystem.
The Kasa Matter mini plug stays compact enough to leave the second outlet free and works across Alexa, Apple Home, Google Home, and SmartThings. Setup is 2.4GHz only, and the first pairing can be fussy on a combined-band router. Already Alexa-only and you just want the lamp or fan on a schedule? The Amazon Smart Plug is the simpler first win. Skip both for space heaters and other high-draw heat loads — the listings and manuals treat those as the wrong category.
