How to detect smart home remote control?

The smart home remote control not only has a radio frequency remote control function (lights, electrical appliances, curtains in a remote control home), but also has an infrared remote control function for multiple home appliances through self-learning. But how to test the smart home wireless network to verify the control functions of electric curtains, electric lights and other home appliances?

Smart home remote control detection mainly includes the following:

1) RF remote control function. With the use of smart series products, you can easily control the lights, electrical appliances, curtains, etc. in your home.

2) Infrared remote control function. Through self-learning, it has infrared remote control functions for multiple home appliances, thereby replacing the existing multiple remote controls and achieving centralized control.

3) scenario setting function . With the use of smart home applications (APPs), lighting, curtains, and electrical appliances can be set to six personalized scenarios.

4) Clock display function. The clock can be displayed.

5) Temperature display function. The ambient temperature can be detected and displayed on the LCD screen.

6) Find function. When the remote control is not within the user's line of sight, the remote control can be located via the "Find" button on the base.

7) Battery undervoltage indication. When the battery voltage is too low, the electric oil symbol in the upper right corner of the remote control's LCD screen flashes.

For some buttons on some home appliance remote controllers (for example, some air conditioners, television switches, and the first infrared signal emitted by the training system are different from those emitted by the second time, these buttons are launched. The infrared code is called ping pong code.

At home, a mobile phone or tablet can replace all remote controls to control all home appliances in the home. It can also be controlled remotely by mobile phones and computers, for example, turning on the air conditioner and floor heating system in the home in advance.

The main factors affecting remote distance of remote smart home controller are as follows:

1) Transmit power. If the transmission power is large, the remote control distance is long, but the power consumption is large and interference is easily generated.

2) Receiving sensitivity . The receiving sensitivity of the receiver is increased, and the remote control distance is increased, but it is susceptible to misoperation or loss of control due to interference.

3) Antenna. The use of linear antennas, parallel to each other, remote control distance, but occupy a large space, in use, the antenna lengthened, straightened can increase the remote control distance: the height of the antenna is higher, the remote distance is farther, but the conditions are limited.

4) Block. The wireless intelligent remote controller uses the UHF band specified by the state, its propagation characteristics and light approximation, straight line propagation, and small diffraction, and if there is a wall blocking between the transmitter and the receiver, the remote control distance will be greatly reduced. If it is a reinforced concrete wall, Then, due to the absorption of electric waves by conductors, the effect is even greater.
