Saswell T29UTW-7-WIFI(TY) Review

Having the right temperature at home can make or break your day. Having a thermostat for your HVAC system helps you control the temperature as per your needs.

Smart thermostats are becoming quite popular these days for their ability to reduce electricity costs by almost $50 a year. They are user-friendly, easily accessible, and more convenient compared to older programmable thermostats.

You can create schedules on them, give voice commands, and operate from them from your smartphones no matter where you are. Most smart thermostats are touch-enabled, which provides the user with simple and easy navigation.

Some thermostats these days also run on learning algorithms that automatically adapt to your schedules so you do not have to make them repeatedly. However, the features of each smart thermostat differ from one model to another.

Choosing a smart thermostat requires some research on your part so that you pick the right one tailored to your HVAC system’s capabilities.

Many users look for which smart home system the thermostat supports, as they want it to connect to the one they have. Most smart thermostats generally support Amazon Echo, Apple HomeKit, and Google Home Assistant, but that does not mean all of them will. Hence, picking the right thermostat depends on many other factors.

Even if your friends or family says that theirs is the best for their HVAC system, that does not guarantee it will be perfect for your home as well. I too made the mistake of buying one based on someone’s recommendation.

While I was doing my research for the right one for me, I came across the Saswell T29UTW-7-WIFI(TY). While it is not as popular as other thermostats such as Nest, Honeywell, or Ecobee, it is still worth checking out.

Who should buysmart thermostats?

Having the right temperature is necessary for many people. Smart thermostats are a great investment if you wish to keep the heating and cooling at your home optimal. Not only does that help you be warm or cool (depending on the weather), but also helps save up on your energy costs.

Some traditional thermostats also do that, but additional convenience, ease of access, and comfort are provided by a smart thermostat. If you wish to give your thermostats voice commands then a smart thermostat is a good investment for you.

Smart thermostats provide additional features such as remote access via your smartphone, so if you have a handicapped person in the house, this would be very useful for them.

Thus, if you have an HVAC system at home and wish to get a new thermostat then a smart one would ease your life. Since additional features and advanced learning capabilities vary for each model you will have to get one that is compatible with your HVAC and smart home systems.

Generally, a smart thermostat is a good option for you if you have a high-speed wifi connection. Having a c-wire connection is often a precondition for most smart thermostats, but there are smart thermostats out there that don’t require you to have a c-wire connection especially installed.

Factors to consider before buying Smart Thermostats:

C-wire connection

The smart thermostats that operate on electrical power instead of batteries sometimes require a c-wire for providing low voltage to your HVAC system. Traditionally thermostats relied on the R wire, but it can be damaging for newer systems. If you do not have a c-wire connection already then you should get one as most smart thermostats rely on it.

Ease of Installation

Installing a thermostat generally is a simple and easy task even if you have not installed one before. Most companies provide a manual or installation guide that can guide you with the help of step-by-step instructions.

You can also find them on youtube. Moreover, the thermostats often properly indicate on the back of the thermostat so that should help you too. However, some thermostats do require professional help especially if they have advanced capabilities.


Geofencing is a common feature in most smart thermostats but some still come without it or have better sensing capabilities. Geofencing typically follows the GPS of your smartphone to assess whether you are home or not.

When you exit the perimeter, the thermostat automatically adjusts the temperature to a less energy-consuming one. Once you enter the perimeter, it returns the temperature to the one you prefer.

HVAC compatibility

If you have a high-voltage heating system, then you will require a thermostat that especially caters to that kind of a system as most only support low-voltage ones.

Smart home integration

Wifi-enabled thermostats allow you to operate your thermostat from your smartphone, but smart thermostats go a step further and integrate with certain smart home systems. They allow you to operate the thermostat with your voice with the help of your smart assistant such as Amazon Alexa, Siri, and Google Home, etc.
