EARLIER: If ever there was a day to turbocharge your smart home setup, Sunday is most definitely the day. Amazon is running a huge one-day smart home sale with not one but two different Gold Box deals, and you’ll find anything and everything you could possibly need.

Starting with the biggest of the two Gold Box’s, Amazon is offering savings of up to 40% on top-rated Meross smart home products. The most popular deal in this batch will almost certainly be the 4-pack of Meross Mini WiFi Smart Plugs for only $23.19. These awesome Alexa and Google Assistant-enabled smart plugs are always affordable, but this deal drops them to just $5.80 a piece!

One more can’t miss deal in this sale is the Meross MSG100 Smart Wi-Fi Garage Door Opener. This awesome gadget links your garage door opener to your home Wi-Fi network and adds smart controls. You can open and close the door with your smartphone, Alexa, Google Assistant, or any smart home system thanks to IFTTT integration. The version that uses a regular wall outlet for power is on sale for $30.55 today instead of $50, and the $60 model that uses USB power is down to $40.79.

Other deals in this big Meross sale include smart light switches at $23.99 per 2-pack, smart dimmer switches at $30.39 per 2-pack, a rugged outdoor smart plug with two outlets for $17.59, and the upgraded version of that same outdoor smart plug that also works with Siri and HomeKit for $27.99.
