Expand HomeKit with Emerson’s versatile Sensi Thermostat: $90 (Reg. $129)

Under $90

Amazon is offering the Emerson Sensi HomeKit Thermostat (ST55) for $89.88 shipped. That’s nearly $40 off what Home Depot charges, beats our last mention by a few bucks, and is the best deal we can find right now. Having owned a HomeKit-compatible thermostat for several years now, I have no desire to backtrack to a standard option. I love being able to tweak temps from my iPhone and it’s a perk that I can do so from Apple’s built-in Home app and Siri. This specific model also works with Assistant and Alexa ensuring that almost any platform can join in the fun. Rated 4.5/5 stars.

Some of my favorite gear

Anker MagSafe 8-in-1 Qi2 USB-C Power Strip

This rapidly tops off my iPhone 16 and adds extra power to my desk.

If the thermostat you’ll be replacing is larger or a different shape, consider grabbing this $6 Emerson Wall Plate. It’s made with this specific thermostat in mind and features a larger design that aims to cover “most marks, holes or any other issues left behind.”

While we’re on the topic of HomeKit-ready smart devices, did you hear about Aqara’s new Smart Wall Switch? Pricing starts at $36 and there are two models that do not need a neutral wire, making this a solid option for older homes.
