About this app

FRITZ!App Smart Home: Clear, convenient, practical

The new FRITZ!App Smart Home is the convenient remote control for your FRITZ! Smart Home devices, at home or from on the go. All you need is a FRITZ!Box with FRITZOS 7.10 or higher.

The FRITZ!App Smart Home is your practical helper, with which you can control many Smart Home functions. You can, for instance:

- use the FRITZ!DECT 200 smart plug to switch on the aquarium, heat up the coffee machine, or disconnect media players and TVs from power overnight.
- use the outdoor FRITZ!DECT 210 smart plug to monitor the cost of charging the e-bike, or to switch on the atmospheric garden lighting.
- use the FRITZ!DECT 301 radiator control to heat the living room to the temperature you like, and save money with automatic heating plans.
- use the FRITZ!DECT 500 LED light to provide for a feel-good atmosphere in the evening, and stimulating lighting in the morning.

In the FRITZ!App Smart Home, the arrangement of the Smart Home devices can be tailored to your own personal wishes – simply place a finger on a tile until it is released, and then move it to the desired position.

Your FRITZ! Smart Home can do even more. You can register new Smart Home devices with your FRITZ!Box by a simple press of the button. It is easy to configure heating plans, automatic switching, templates and groups in the user interface of your FRITZ!Box. The FRITZ!DECT 400 switches your floor lamp in the living room or your outside lighting via FRITZ!DECT 200 and FRITZ!DECT 210. Our latest product is the FRITZ!DECT 440 switch with four buttons and a display. FRITZ!DECT 440 can dim your FRITZ!DECT 500 LED light, for instance, and measure the temperature for FRITZ!DECT 301.

Tip: Expand the possibilities in your FRITZ! Smart Home today with the upcoming FRITZ!OS for the FRITZ!Box. The software includes completely redesigned operation of the Smart Home in the FRITZ!Box user interface, new functions for the 4-button FRITZ!DECT 440 switch, and presents a whole range of colors in its support for the new FRITZ!DECT 500 LED light. The new FRITZ!OS is available for you to test in the FRITZ! Lab at en.fritz.com/fritz-lab.

Prerequisite
FRITZ!Box with FRITZ!OS version 7.10 or higher
If the internet connection of your FRITZ!Box does not have a public IPv4 address, there may be some restrictions to use on the go in some mobile or Wi-Fi networks.


Frequently asked questions:

Question: How can I register with another FRITZ!Box?

The FRITZ!App Smart Home supports the operation on exactly one FRITZ!Box. If you want to change the FRITZ!Box, select "New Login" in the settings. To log on to the FRITZ!Box, you must be connected to the Wi-Fi of your FRITZ!Box.

Question: Why can't I access my FRITZ!Box when I'm on the move?

Make sure that you have activated "Use on the move" in the settings. To change the settings, you must be connected to the Wi-Fi of your FRITZ!Box.

Some Internet service providers (increasingly cable providers) provide connections where remote access from the Internet to the connection at home is not possible or only possible with restrictions because no public IPv4 address is provided. The FRITZ!App Smart Home usually detects such connections automatically and displays a corresponding message. Such connection types are called "DS-Lite", "Dual-Stack-Lite" or "Carrier Grade NAT" (CGN). If necessary, you can ask your provider whether there is an option to obtain a public IPv4 address.

That's a good app, but I miss the possibility to see the exact time associated with the values (power and temperature) on the graphs of my DECT 200. While sliding on the "Energy display" and "Temperature profile", the corresponding values (power or temperature) are shown on top of the graph, but the time corresponding to these values can only be guessed approximately. Could you please add the time next to the actual values?

Thank you for your feedback. We have taken note of your request to display the measurement time separately.

Seems to load significantly slower on Android than on iPhone in my case. Edit: The outdated look seems to have been based on screen size, font size and night mode giving me something that looked rather dated compared to the screenshots here. Have corrected the rating.

app works fine with a 2 minute delay on the heating units. But everytime I open the app, I get a security certificate error. And that I have to press trust. Tried to reinstall the app, and make a custom certificate via the Fritzapp. But nothing works.
