Nest Thermostat E

That's a good question. It's not recommended but it can work. The reason that it's not recommended is the usage. The Nest device requires a constant connection. Does this help to clarify that for you?

Nest - 3rd Generation - The latest Nest Learning Thermostat works with almost every type of HVAC system, has a display that's readable from across the room, and supports Farsight making the clock and text bigger so you can read it from across the room. It even comes in seven different colors for you to choose from. It's not cheap, though. Nest E - The Nest E is the least expensive model from the company and does almost everything the pricier model can. You'll be able to control it using your app or a smart assistant. It does lack Farsight, and the display is pretty basic, though. Additionally, it doesn't work with as many HVAC systems. - Takendra
