Why Purchase a WiFi Thermostat?

A WiFi Thermostat is generally, well, a lot smarter tcontrolling thermostat with phone apphan the old versions that were difficult to program and didn’t work very well.  They can generally be controlled from your smart phone, some program themselves, and they can save you money on your energy bills.Here are some general advantages of a Smart Thermostat over their older programmable models.

  • They are easily programmable from a smart phone, tablet, or computer.
  • You can change the temperature in your home from your smart phone or setup a programmable schedule from the phone app.
  • Some Smart Thermostats actually “learn” your schedule and will adjust the temperature automatically.
  • Most smart thermostats actually save usage data so you can run reports and see how you can save even more on your energy bills.
  • Some models are compatible with home automation systems like Amazon’s Echo allowing you to control the thermostat with voice commands.
  • Save money on your electric and gas bills through home automation.

Things to Consider When Buying

Is your phone compatible: One of the biggest reasons people purchase smphone application for thermostatart thermostats is the ease of programming them with your smart phone.  Most of your popular brands will work with both Apple and Android devices but not all of them will.  Make sure you
buy a smart thermostat that has an app for your particular operating system.  It may even be a good idea to make sure it is compatible with both in case you want to switch your type of phone or someone in your house does.

Future home automation: Speaking of compatibility you want to have a plan for your current or future home automation needs.  Some Smart Thermostats have voice commands built-in which is great.  The only downside is they may not work with Alexa or other home automation products.  You could end up using one device for voice control of your thermostat and another your lights.

C wire: Another issue to consider is if your current thermostat already thermostat wiringhas a C wire installed or not.  If you aren’t familiar with what a C wire is or how to check if you have one go here to learn more.  If your home does not have a common wire you may want to look at a model like the Sensi Thermostat that does not require a common wire.

System compatibility: The final major factor you want to consider is one that most people may not think of.  Does the smart thermostat work with your type of heating system.  Most of the major brands work with 95% of HVAC systems.  If your system isn’t a very commonly used form of heating or cooling I would pay close attention to this.  Nothing would be more disappointing than getting your smart thermostat home and realizing it won’t work with your system.

Best WiFi Thermostat for Vacation Homes

If you own a vacation home you know how frustrating it can be not knowing if the heat is actually working when you are away.  What if the heat goes out during the winter?  The advantage of having a WiFi thermostat for your vacation home are

  • Monitor the temperature in the home from  your smart phone, tablet, or PC
  • Easily program a schedule when you aren’t going to be in the vacation home for energy savings
  • Setup e-mail alerts if the temperature gets too high or low
  • Pre-heat your home when you are on your way so you don’t have to be cold or hot when you arrive

All of the smart thermostats reviewed on this page will be a major upgrade over a thermostat without WiFi for a vacation home.

Thermostat C Wire

I have an entire page dedicated to the C Wire but here is a quick run down.  Most smart thermostats need a continuous power source.  They gefurnace wiringt this power from a common wire or C wire for short.  Older models didn’t require one so you may have to install the wire if it is missing.  There are a few models that do not require the C wire or come with an adapter to make installing one easy.If you are unsure if you have a c wire or how to install one check out my page on C wires.  If you don’t have the wire I would still consider a smart thermostat.  You can purchase the wire extender or purchase a thermostat that does not require one.  The convenience and cost savings you get from a WiFi enabled thermostat is well worth the few extra steps.

WiFi Thermostats With No C Wire

If you absolutely don’t want to worry about the whole C wire issue? Don’t worry you are still in luck.  While your choices may be limited you can still get all the benefits of a smart thermostat.The Sensi Thermostat does not require a C wire at all for most installations.  It is a great thermostat and the easiest to install.  You still get all of these features

  • Programmable with your smart phone
  • Accessible via WiFi
  • Control the thermostat from any where in the world
  • And no C wire is required

Your next option is the Ecobee thermostat.  While you still technically need a c wire they include an adapter that only has a few extra steps to install.  Most reviewers have installed this thermostat with the adapter in under an hour without any major issues.  Not to mention the Ecobee is an amazing smart thermostat.  Especially if your home has multiple zones or is larger than an average home.

Installing a WiFi Thermostat

If you can change out an electrical outlet you can easily install a WiFiecobee wifi thermostat thermostat.  All you generally need is a screw driver to complete the task and all the smart thermostats come with easy to read instructions.  Just write down where your current wires are connected and match that to the smart thermostat.  The only exception is if you need to add a C wire and you have many options if you don’t currently have one.  All of that is explained on my C wire page.
