Its operations allow you to stay connected through the app, and the home assistant of these thermostats can save you money on energy bills and turn off the devices when you are not home.

Modern-day thermostats are packed with many features and functions that bring ease to life and allow us to control the thermostat in different ways. If you wish to get a system but not ready to invest big, you can choose to get a cheap smart thermostat. Inexpensive thermostats also offer similar benefits with a little bit of difference.

Getting new technology sometimes is not easy because manufacturers charge for new functions and features. The same case is here, and the most modern devices are costly near the three times of cheap devices.

What is a Cheap Thermostat?
In this category below, I only considered cheap and affordable thermostats. I list some of the best devices which are priced reasonably.

What Will Be Missing In A Cheap Thermostat
It’s a million-dollar question. When you pay more for Google Nest, Honeywell, Ecobee, or Emerson Sensi you are getting some extra features against the higher price tag. I try my best to figure out the main differences between the most advance and cheap thermostat. Some of them are:

Inexpensive thermostats are not good learners; not made to learn the schedules and routines.
Room Sensor Support is not provided in cheap thermostats.
The home assistant is missing or poorly designed.
A most simple and straightforward app that lacks in many areas.
Inexpensive thermostats look traditional, not futuristic.
Hundreds of products are available below 100$, but we listed below a few of them which are successful, and customers are happy with them and offering similar benefits of costly thermostats. We recently reviewed the best smart thermostat for multiple zones and top-rated thermostats, which are hot selling items nowadays. Let’s move to the list of affordable products:

It’s fast and responsive and works with WiFi, so you can stay sure wherever you can see the temperature inside your house and also can amend the schedule and timers remotely.

Why do I recommend it most? The reason for me is its compatibility with all old and new HVAC and other heating and cooling systems. I do not find any incompatible system name a system, and it’s compatible with that. I believe that it’s highly consistent and most simple to install for novice smart homeowners.

It’s one that sold in thousands of numbers, and it’s one that is initial but most effective from Honeywell. The majority of customers love this thermostat because it’s compatible with any system. I try to find any incompatible system but did not find any. It’s not only a cheap thermostat, but it’s also one that offers all the features that one can expect from the most modern thermostats.

Equipped with smart response technology that will automatically follow your schedule and provide you with the environment that you like most, it can set the temperature you use most of the time without any intervention.

Its four programming periods allow setting the different temperatures in different time zones of a day. I also like its large display, which is easy to read and display all the necessary information and makes setting easy.

If you think that buying a cheap thermostat may lose some functionality, then it’s not a real issue here; instead of functionality, you may not get some of the features. Still, functionality is similar, and the app act as a remote from which you can access the thermostat from any part of the world. Information about local weather is also accessible on the app.

It’s cheap but loaded with WiFi connectivity, which is an utmost requirement of modern days to stay connected with the device.

The app allows you to amend the schedule and current temperature and better control over the device.

I personally test this thermostat; the number one factor of consideration for me was its price. I found its WiFi is a bit unstable, and its connectivity to Alexa sometimes a little bit slow, but when I installed it near the WiFi router where signals were strong it works fine. So it’s my advice for you to install it in the strong signal area or bring your WiFi hub near to it to keep it connected all the time.

Its modern design and large display allow accessing features and functions quickly. Its interface is also user-friendly, and its remote app is easy to understand.

I found that it also has WiFi connectivity issues during the review, just like other Vine thermostats. It only works fine when it’s installed in a strong WiFi area. From strong, I mean four signals. At least otherwise, you will suffer from the continuous disconnection. It’s an area where Vine needs to focus on. While its software is quick and app response is excellent, you can expect fast operations from this thermostat.

Final Thoughts
There is a number of other poorly rated products in the market. I know many people who bought newly launched products from unknown manufacturers and even from those who are poorly rated but in the end, they give up and spend a handsome budget again to buy a device that can work smartly.

Before buying any device, just make sure that enough customers bought that device and they are quite satisfied with their purchase, especially when you are not buying for experimental purposes. I am sure you will get one that fits your budget.

I recommend Emerson Sensi Wi-Fi Smart Thermostat most because this a thermostat that is compatible with all systems and works with C-wire. You can hardly name a system that is incompatible with it. All the modern voice controllers work this system, and its app allows us to have full control over the device operations. So if you really decide to buy a budget-friendly product, then it’s one that I recommend for you.
