Buying Guide For The Best Thermostat in India

As we mentioned earlier, there are a lot of options to choose from when it comes to buying a smart thermostat, where each option will give you a distinct set of features. Almost all of the options that you came across by now has a different price tag and features the specifications accordingly.

Therefore, you need to make sure that you are getting the best option available for your budget to have a long and reliable experience with the smart thermostat. In our buying guide, you can find many different aspects that you should check while buying a smart thermostat to make sure that it will perfectly suffice for your needs without needing any extra peripheral. Therefore, we can assure you that you can certainly get hold of at least one of our best smart thermostats in India once you have gone through our buying guide.

1. Compatibility

As you are looking for a thermostat, it is safe to assume that you already own a thermal management system installed in your home that you will be controlled with the smart thermostat. But, not all of the options will be compatible with your thermal control unit as each option has a separate requirement.

The most important factor is whether your thermostat requires a C wire to operate or not. The common wire, known as the C wire, provides a constant current to WiFi-enabled thermostat. In most of the smart thermostat variants, you will have to include a C wire connection so that it can work properly. If your system does not have a C wire, you should look for a preferred thermostat for your system or look for one that has an options adapter included for such a case.

2. UI and Manual Control

The user interface is crucial when it comes to home comfort devices as it is going to be used by multiple people living in the family. This included kids as well as elderly users that prefer a simpler control as complicated user interfaces are often confusing and hard to understand.

Before buying a smart thermostat, you can check out the applications supported by the thermostat and check out the app right on your smartphone to get a better idea about it’s UI. Also, make sure you pay attention to the manual control settings available on the thermostat body itself, as you might not have access to your smartphone at all times and might have to change the parameters manually many times.

3. Remote Access

One of the greatest features of current generation smart appliances is WiFi compatibility and the fact that it can be controlled remotely from anywhere, given that you have a stable internet connection available for both your home network and smartphone. In all of the smart thermostats mentioned here today, you will get dedicated wireless support so that you can pair the device with your home network and set it up for remote access.

But, a few advanced remote access features such as automatic control and alerts are only available with a few options, whereas basic features like turn on/off, temperature control can be found with all picks. If you are also interested in advanced remote access features, make sure you check that carefully before buying. Also, you should double-check if the app you use for basic home integration is supported by the thermostat or not.

4. Reliability

Thermostats are one of the few appliances in your home that comes at a very expensive price tag, and you mostly will not be replacing it for multiple years. In such a case, it is crucial to make sure whether a device is suitable for long term use or not. There are many standards systems like Energy Star that carefully review the unit and gives it a suitable standard rating.

You can follow such ratings to make sure the device you are going to buy is one of the best options available in your budget. Also, you should check the warranty period available with the smart thermostat as the ones with a longer warranty period are often more reliable and durable. And you can avail free of cost repairs or even replacement in case you receive a faulty product within the warranty period.

Frequently Asked Questions

1.Is it difficult to install a smart thermostat?
Installing a smart thermostat is as easy as any other thermostat because it requires the same connections and comes with predefined wiring suggestions. If you have installed a thermostat before, you can easily get the installation finished within half an hour or so with the new one. In case this is our first time installing a thermostat, we will recommend you to go through the user manual available with all options or call professional help for a safer installation.

2.What to look for in a smart thermostat?
As the name suggests, a smart thermostat needs to be unique and functional. Not only just the functionality but also the look and feel of the thermostat should be subtle so that it matches the decor of your room and does not end up standing out in your living room.

Most of the smart thermostats mentioned on our list feature direct WiFi connectivity, which is the most reliable and secure option available. Not to mention, it is also the fastest connectivity option and allows remote access if you have a stable internet connection.

All of our picks are smart options and support wireless operation, and also voice-activated commands thanks to Google as well as Alexa voice assistant support.
