Room temperature

Ideal room temperature thanks to smart home control

What is the ideal room temperature?

On cold days, you're certainly glad to come home to a warm flat and no longer have to freeze. But what is the ideal room temperature? On average, the temperature in your home should be around 20 degrees. Some rooms can manage with less heat, while others can be a few degrees warmer.

By the way: Room temperature and room temperature are not the same thing. Room temperature is the temperature that is measured with a thermometer in the room. The room temperature is the temperature that you subjectively perceive in the room.

So what are the optimum temperatures in the individual rooms?

Optimum room temperature in the bathroom

You certainly don't want to be shivering after a bath or shower. That's why the temperature in the bathroom can be slightly higher than in the rest of the home. The guideline is 22 to 23 degrees Celsius in the bathroom. It is important that you ventilate the room sufficiently after showering so that moisture can escape. This will prevent mold from forming.

Tip: If you are looking for a smart sensor for your bathroom that precisely measures temperature and humidity, take a look at our Shelly BLU H&T. It is protected against splash water and therefore ideally suited for use in bathrooms.

Best air temperature in the bedroom

For a good night's sleep, the temperature in the bedroom should be between 18 and 20 degrees Celsius, but never higher. Many people also find 16 or 17 degrees at night comfortable. It is important that you neither sweat nor freeze while sleeping. During the day, you should keep the bedroom door closed to keep the cool air in the room. Before going to bed, it is advisable to air the room briefly.

Ideal room temperature in the living room

You usually spend most of the day in the living room. As you don't move around much on the sofa or while watching TV, the living room can be slightly warmer than the rest of the home. 20 to 23 degrees Celsius is considered ideal and is perceived as pleasant by most people.

Perfect temperature in the kitchen

The oven, hob and fridge in the kitchen give off heat, so that the heating doesn't have to work as hard there as in other rooms. You can therefore set the temperature in the kitchen lower than elsewhere. The optimum room temperature for the kitchen is between 17 and 20 degrees Celsius.

Tip: If you want to measure and control the temperature in the kitchen precisely, the H&T Gen3 sensor is ideal. In the event of temperature fluctuations, for example before, during and after cooking, it sends the command to the respective smart heating control unit that the heating should react accordingly.

Here is an overview of what the ideal room temperature should be depending on how the room is used.

How do I measure the temperature?

It is not so easy to determine the exact temperature of a room. This is because the temperature can vary depending on where you are in a room. It is best to measure the temperature with an analogue or digital thermometer in the middle of the room, about one metre from the floor. The thermometer should not be near the heating or in a very sunny spot in the room, as this can falsify the result.

Tip: Temperature and humidity measurement is much easier with sensors from Shelly, for example with the H&T Gen3. If the temperature in a room falls below a selected number of degrees, the sensor forwards the information to the relevant smart heating control unit, which automatically switches the heating on. If the temperature rises above the specified value, the heating switches off automatically.

How do I maintain the ideal room temperature?

Wouldn't it be practical if you didn't have to constantly turn the heating up and down, but the room temperature remained constant and ideal? Shelly products make this very easy.

Control room temperature with radiators: As you probably know, you should ventilate several times a day - in other words, open the windows fully for a few minutes. To avoid wasting energy during this time, you should always turn down the heating during ventilation. The Shelly BLU TRV radiator valve, which is installed on a radiator and makes heating control smart, helps you to do this. It's very easy: simply unscrew the old radiator valve, screw on the BLU TRV, pair it with the BLU Gateway Gen3 supplied and control it with the app.Connect.

Control room temperature with an electric heater

You can also maintain the room temperature with an electric heater. You can do this by connecting it to the Shelly Plug or Shelly Plug S Gen3 smart sockets. This is also done quickly: plug the plug of the electric heater into the Plug or Plug S Gen3, plug the Shelly device into the socket and then connect it to the Shelly app.

This allows you to combine the electric heating with other Shelly devices and automate the heating control. The advantage of Shelly Plug S Gen3: The socket is Matter-compatible, so it can also be connected to devices from other brands. You can also control the connected devices via the Apple Homekit app or Siri.

Control room temperature via the underfloor heating

You can also make underfloor heating smart and control it as required. There are various options depending on the design of your underfloor heating system: If your underfloor heating has a valve, you can use the Shelly BLU TRV. You can connect a relay such as the smart switch Shelly 1 Gen3 or the smaller version Shelly 1 Mini Gen3 to the manual controller of the underfloor heating. We explain how this works here.
