Apps like Google Home or LG ThinQ allow you to not only change channels, but also access streaming platforms, adjust the volume and even set up user profiles.
For older TVs, adapters like Chromecast or Roku transform conventional devices into smart TVs, allowing control via smartphone.
Practical example: João, a university student from São Paulo, uses the Remote TV app on his Android phone to control the TV in the living room shared with his colleagues.
It connects your phone to the TV via Wi-Fi, selects Netflix directly from the app and adjusts the volume without getting up from the sofa.
Setup took less than five minutes, and now he avoids arguments over who lost physical control.
The table below summarizes the main applications for controlling TVs:
| Application | Compatibility | Key Features |
|---|---|---|

Climate control on command: air conditioning and cell phones
When the Brazilian summer heat hits, nothing is more valuable than air conditioning.
Using your cell phone as a remote control for these devices is a solution that combines practicality and energy savings.
Brands like Daikin and Gree offer apps that allow you to turn on your air conditioning remotely, adjust the temperature and schedule operating times.
Some newer models, such as those in the Inverter line, support integration with virtual assistants such as Alexa, controlled directly by the cell phone.
Original example: Mariana, an entrepreneur from Recife, uses the Daikin Mobile app to turn on the air conditioning in her office 20 minutes before arriving.
This way, the environment is already cool, and it saves energy by programming the automatic shutdown after work hours.
The app also notifies you when the filter needs cleaning, extending the life of the device.
Energy savings are a tangible benefit.
According to the National Electric Energy Agency (ANEEL), programming air conditioning units to operate at specific times can reduce consumption by up to 15%.
Using your cell phone as a remote control makes this programming easier, bringing comfort and sustainability.
Additionally, the ability to monitor energy consumption through the app allows users to make adjustments to further optimize energy efficiency.
This environmental awareness is increasingly important in a world that seeks sustainable solutions.

Smart lighting is transforming Brazilian homes, and the smartphone is the conductor of this orchestra.
Systems such as Philips Hue, Yeelight and TP-Link allow you to use your cell phone as a remote control to adjust the intensity, color and even create lighting scenes.
Want warm lighting for a romantic dinner or vibrant lighting for a party?
All this is just a tap away.
The perfect analogy is to think of your cell phone as a digital paintbrush: each light adjustment is a brushstroke that colors the environment according to your mood or need.
Apps like Hue Sync, for example, synchronize your lights with your TV content, creating an immersive experience for movies and games.
Additionally, integration with assistants such as Google Assistant allows voice commands, such as “turn on the living room light” directly from your cell phone.
The table below compares three popular smart lighting systems:
| System | Average Price (R$) | Highlights |
