Advantages of Smart thermostats
Choosing an Alexa thermostat is great for several reasons:
As you use the voice command feature, you can be doing anything else in the house and simply ask your voice assistant to change the temperature. You will not even require your smartphone or the device to change the temperature.
Instead of manually adjusting the thermostat each time, you can simply program a smart thermostat in advance. Some smart thermostats come with premade modes so scheduling is made even simpler.
Smart thermostats save energy in the long-run because of their smart features. Their ability to adjust the temperature when no one is around is great. Thermostats with smart sensors are better at this because they are constantly monitoring the temperature.
Things to consider before choosing the best Alexa smart thermostat
Here are some considerations to keep in mind while you select a solar-powered water pump.
The thermostat and HVAC system should have the same voltage requirements. Most HVAC systems have a 24V power but multi-stage systems, furnaces, or ACs have different voltage. These thermostats have different stages of heating and cooling and so need thermostats that are supported by them. Thus before investing in a thermostat make sure it is compatible with the HVAC system at home.
Ease of Installation
Most thermostats can be installed at home without much difficulty with the help of the manuals but others need a professional installation done. Moreover, if there is a c-wire with the thermostat then you need to make sure there is a c-wire connection with the HVAC system. The c-wire ensures continuous connectivity to the internet. Thus, if you do not want to get a c-wire connection installed then make sure you get a thermostat that does not have complicated wiring.
Monthly Reports and Reminders
Some thermostats also track your energy patterns and present reports so that you can better schedule your thermostat. This also helps in saving more energy. Many smart thermostats also give reminders for instance when the filter needs to be changed. Some also give alerts when the temperature goes too high or too low.
Some thermostats are smarter than others and have features that involve lesser involvement from the user. They have algorithms that learn the user’s usage patterns and then use them to automatically make changes to temperature accordingly. These, however, are generally more expensive than basic smart thermostats, such as the [amazon link=”B0131RG6VK” title=” Nest Learning Thermostat (3rd Generation)” /] .
Smart thermostats that support Alexa are great for people who already have an Alexa device at home. They allow you to change the thermostat without getting up or finding your smartphone However, if you do not have an Alexa device then you could also opt for a smart thermostat that comes with built-in Alexa such as the [amazon link=”B07NQT85FC” title=”Ecobee Smart Thermostat” /] . It is also our best overall Alexa-enabled thermostat.
Smart thermostats however need other considerations as well. The price, the features, and its compatibility with the HVAC system also matter. Some thermostats, for instance, come with remote sensors that allow you to have different temperatures in all rooms of the house. The [amazon link=”B07N849J21″ title=”Honeywell Home T9″ /] is a good option for that especially if you have larger rooms.
