Amazon's smart thermostat falls to a new all-time low of $42 ahead of Prime Day

Almost a week before Prime Day, Amazon has begun selling a bunch of its smart home devices at a discounted price. You can get a smart thermostat from Amazon for $42 if you're a Prime member. It is a new all-time low for the device, and is 30 percent off its regular retail price. You can control your home temperature with the Amazon smart thermostat.

It isn't as feature rich as the more expensive ones. It's Energy Star certified and can save you $50 on your electric bill every year. You can use the voice assistant to set your own heating and cooling routines. The thermostat doesn't have a speaker or microphone, so you'll need to use a device that's connected to the internet, such as an Amazon device.

Right now, you can get a smart thermostat bundled with an echo dot speaker. It's the lowest we've seen for it on the website, and it's a bundle with a fourth-gen echo dot speaker. The smart thermostat bundle with a second-gen Echo Show 5 smart display is on sale for less than its retail price. That is a new all-time low for the duo.

You can get a fourth-gen echo dot with an Amazon smart plug for $25. If you have an Amazon smart plug, you can control any non-smart device plugged into it, such as lights, fans and other appliances.

You can get the fourth-gen echo dot for kids bundled with an echo glow multicolor smart lamp with prime for $36 It's 60 percent off its retail price and comes with a year-long Amazon Kids+ subscription.
