Anker makes smart plugs now, because Anker makes everything, and they’re down to their lowest prices ever today when you clip the 15% coupons on the product pages.
Like pretty much all of these things, you can control or schedule it with both your phone and with Alexa, and their built-in energy monitoring feature is a great feature at this price. The coupon is available both for the original, square model and the new, compact (i.e. non-outlet-blocking) version, though the older one is a few bucks cheaper.
