Bosch BCC100 Connected Control Review

Standard programmable thermostats are energy-saving but only if they have been programmed right. A smart thermostat on the other hand uses technology that allows the thermostat to save energy while running optimally.

So, when no one is home, the smart thermostat automatically adjusts the temperature to a more energy-saving one. Smart thermostats are often easy to install, although some might require a c-wire.

The c-wire ensures constant connectivity to the wifi, however not all smart thermostats need one, although it is recommended. So, if you already have a connection, then you can easily install the thermostat without any professional help.

Most smart thermostats provide users with the comfort of changing the settings through other smart devices. Smart thermostats come with smartphone apps that can be downloaded on the user’s smartphone, tablet, PC, etc.

They can also be controlled by voice assistants given that the thermostat is compatible with your smart home system. Thus, not only do they provide remote access but can be controlled with your voice also.

Smart thermostats allow you to keep track of your energy usage. You can see your progress and can see other statistics that help you minimize energy costs even more. Some thermostats also come with sensors and advanced learning capabilities that add to your comfort even more.

Distinctive Features

While all wifi thermostats come with programmability and smartphone apps, other features can vary from one thermostat to another. Moreover, smart thermostats can differ greatly also in terms of price.

Thus, at the end of the day choosing the right smart thermostat comes down to a few factors including your budget. Buying one based on someone else’s recommendation is not a good idea as it may not be compatible with your systems.

I also made the mistake of buying one that was not compatible with my HVAC system. Thus while I was researching for one I came across the Bosch BCC100  smart thermostat.

This review is a helpful guide for anyone interested in purchasing the Bosch BCC100. By the end of it, you will know whether this or some other alternative is better suited to you.

Who Should Buy Smart Thermostats?

First and foremost, if you are someone looking to reduce your heating and cooling expense, then a smart thermostat is a must-have. Not only will it help you save on your energy costs but will also be smart enough to adjust the temperature when no one is home.

Therefore, a smart thermostat is suitable for people who travel frequently or have to leave the house multiple times a day. It will save you the hassle of constantly switching your thermostat on and off as most smart thermostats are equipped with geofencing or sensors.

Smart thermostats have an aesthetic appeal to them that traditional thermostats do not. Most smart thermostats have LCD touchscreens that complement any kind of home. Moreover, if you already have an HVAC system and a smart home system, then getting a smart thermostat will be very beneficial.

You can integrate your smart home system with the thermostat which will allow you to give your thermostat voice commands. Hence, you don’t even need a smartphone to adjust the thermostat if you have a smart home system that is compatible with it.

Smart thermostats not just make your lives easier, but they also produce reports at the end of each month for you to track your energy usage. Smart thermostats may be a hefty investment but it will be worth it.

Factors to Consider Before Buying Smart Thermostats:


Since smart thermostats can be expensive, it is a good idea to see how long the warranty lasts. You do not want a thermostat that you spend hundreds of dollars on, only for it to malfunction after a couple of years of use. Usually, the warranties start from 2 years and go up to 5. However, the length varies with each thermostat and brand.

Ease of Installation

If you want a DIY installation, then you should check the manual available online and decide whether the installation seems simple for you. Professional installations are expensive, although sometimes you don’t have an option because the wiring is too complex.


A smart thermostat’s interface is a very important feature. Not only does it add to the aesthetics of the home, but also allows you to have ease of use while choosing the settings.

Understanding the information on the interface is also important, thus you should see the interface at play before you buy it. Some interfaces can be quite hard to understand and the point of a smart thermostat is to add to your comfort, and not vice versa.


This feature is found in almost all smart thermostat, and if your thermostat doesn’t have it, then you might want to reconsider.

It helps you save up on your energy costs as the thermostat detects whether your phone’s GPS signals are within the specified radius or not. If it doesn’t detect the signal, then it will automatically change the temperature that uses less energy.

Smart Home Integration

This feature is great for users who already have smart home systems at home. The popular smart home systems include Amazon Echo, Apple HomeKit, and Google Home. All thermostats vary in their compatibility for smart home systems, and so it is crucial to make sure the thermostat you want to get is compatible with the thermostat.
