After a couple weeks of learning, you can switch to a PID (proportional integral derivative) control. This uses predictive and learned behavior to provide the best heating experience possible. PID control looks at weather conditions, and adjusts its cycling to compensate for it. For example, if a sudden cold front is expected, the system will turn on earlier than normal to ensure the temperature stays at a comfortable level. Also, PID takes into consideration your house's insulation properties, which let it perform better than merely waiting until the temperature reaches the upper/lower setpoint values.

Pro Energy tracking built-in
You will be able to view energy reports from the daily, weekly, monthly or yearly view. This can help you save up to 37% on your power bill (and help pay off the thermostat itself) by recognizing high power times and adjusting the temperature to save power during those times.
Pro Works with Android, iOS, Windows Phone, and has a web app
No matter if your family is divided across mobile platforms, everybody can still control the Netatmo Thermostat. There is also a web app, so it can be controlled using a computer or on other phones and tablets by logging in to the web app.
Pro Great customizable scheduling system
You can set the schedule to virtually anything you could want - multiple heating and cooling periods each day, and you can even save different schedules and switch between them with the tap of a button in the app if you so choose.
Pro Room-by-room control, scheduling, and heating
Because each Eve Thermo is assigned to a single room, it can accomplish a steadier temperature than a single central thermostat. You can assign each room to a different schedule, for example your bedroom heater can be turned off during the day while the rest of your house receives the heat instead.
Pro Small, sleek looking hardware
The Eve Thermo is physically small, and plugs into your heaters which are usually hidden out of sight. This allows it to discreetly add smart heating to your house without creating an eye-sore on a prominent wall.
If the device is in a location where it will be seen however, it looks very sleek with it's polished white colour and rounded square design.
Con Hardware feels basic
While other smart thermostats let you use the thermostat itself for virtually any adjustments, the Netatmo Thermostat only displays the setpoint temperature (in bold black) and the current temperature (outlined).
The display is E-ink, which doesn't look as good as good as LCDs and can't display colours. Also, there is no backlight making it impossible to see with the lights off.
Con Limited controls on the thermostat itself
On the thermostat itself, you can only change the temperature. All other controls must be implemented from the app on your phone, through Siri, or through the web app.
Con Only available in the UK
Con Not a whole-house unit
The Eve Thermo only connects to a single heating element. That means that for your entire house to be heated this way, you'd need one Thermo for every room in your house - at which point it would be much more cost-effective to get a single smart thermostat.
The Eve Thermo is better suited as a complementary device - one that is installed alongside your current (or future) thermostat. The Eve Thermo works very well when it comes to regulating temperature in a tricky room (where a normal thermostat leaves it either too warm or too cold), and that is where it excels.
Con Powered by disposable AA batteries
The battery life is expected to be about 8 months, which is pretty good. However, you will need to replace the batteries from time to time which also adds to the overall cost of this product.
Con Limited control distance
The Eve Thermo only connects via Bluetooth, and has a short range (~4 meters). You won't be able to adjust the temperature from outside the room, unless you have an Apple TV 3rd gen (the Apple TV hooks up to the Thermo, and allows control through Wi-Fi which can be accessed and adjusted from anywhere in the world with an internet connection).
