Wi-Fi Smart Thermostats Under $45: Which Commercial Electric Model Should You Buy?

Compare four Commercial Electric Wi-Fi and Bluetooth smart thermostats priced from $29.95 to $44.75. New and open-box options are covered, with advice on choosing based on included extras and control style.

Last updated Aug 17, 2026

Picking a smart thermostat is no longer just about setting a schedule. You have to weigh Wi-Fi and Bluetooth vs. simple app control, decide between new and open-box condition, and figure out which included extras actually matter for your HVAC setup. The four Commercial Electric options here all share a white finish, but their prices range from $29.95 to $44.75, and they differ in how you control them and what's in the box. Here's how to match the right one to your home.

Quick Take

Four Commercial Electric smart thermostats, all in white, fall into two new and two open-box groups. The two new units sit just four cents apart, which puts the focus on extras like the C-Wire adapter that comes with the cheapest option. At the other end, the Alexa-enabled open-box model is the priciest option. For most homes, a new sub-$30 unit with app scheduling is the sensible starting point.

Product Notes

Commercial Electric Wi-Fi and Bluetooth Enabled Smart Programmable Thermostat (New)

Commercial Electric Wi-Fi and Bluetooth Enabled Smart Programmable Thermostat

This is the least expensive option and one of only two that are new. A C-Wire adapter is included, along with a 30-minute installation guide, and the Hubspace app allows custom schedules. It works with Google Assistant and Alexa, so you can adjust temperature by voice. The unit is hardwired, which means you need a proper wiring location; a battery-only installation isn't part of the package. If your main goal is a low-cost, voice-compatible smart thermostat with a C-Wire adapter, this is the one to start with.

Commercial Electric Wi-Fi and Bluetooth Enabled Smart Programmable Thermostat (Open Box)

Commercial Electric Wi-Fi and Bluetooth Enabled Smart Programmable Thermostat

This open-box unit is described as like new and still in original packaging, but the user manual is missing. That's the trade-off to weigh. Mounting hardware is included, two heat and two cool stages are supported, and Bluetooth is on board. The controls are digital and Wi-Fi-based, so you can still set schedules. At $34.99, it sits in the middle of the price range, so you're paying a little more than the new units for a like-new item without a manual. If a paper guide isn't essential and you want mounting hardware, this is a workable open-box route.

Commercial Electric Wi-Fi Bluetooth Alexa Enabled Smart Programmable Thermostat (Open Box)

Commercial Electric Wi-Fi Bluetooth Alexa Enabled Smart Programmable Thermostat

This Alexa-enabled model is the most expensive of the four and is open box. It offers a control set that includes touch and Wi-Fi. A 3.54-inch display is included, and the unit is described as universally compatible. The main limitation is the price gap: it costs $14.80 more than the cheapest new thermostat, and it's still open box. If you want touch control and a larger screen, this is the option to look at. If you can live with a standard setup, the new units give you a less expensive route.

This new unit at $29.99 is the second new option in the group and includes mounting hardware. It's wall-mounted and made of plastic, with Bluetooth and Wi-Fi controls. The wall-mount requirement means you'll need a permanent spot on a wall, so a tabletop installation isn't possible. If you want a new thermostat that includes mounting hardware, this is a practical pick. The price is only four cents above the cheapest unit, so the decision between the two new models comes down to which bundled extra you need.

Final Recommendation by Use Case

If you want a new thermostat at the lowest listed price, the first Wi-Fi and Bluetooth Smart Programmable Thermostat is the clear pick. If you'd rather have the other new unit, choose the New Commercial Electric Wi-Fi Bluetooth Enabled Smart Thermostat 1010 676 212. If you're open to open-box condition and don't need a printed manual, the mid-price open-box thermostat is a workable choice. And the open-box Alexa model is for when you're willing to pay for extra capabilities.
