For mobile phones without infrared devices, if the BroadLink universal remote control RM Pro is available, the Xiaomi mobile phone can become a universal remote control with simple settings. BroadLink universal remote control RM Pro is an upgraded version of the first generation RM Home. RM Pro adds 315 and 433M radio frequency remote control and timing functions to support more devices, and the timing function increases the operability of the device.

The relevant parameters of the BroadLink universal remote control RM Pro are as follows:

BroadLink universal remote control RM Pro has a unique arc triangle shape and uses special infrared transmission materials, which reduces the red diffuse reflection, and the infrared penetration rate reaches more than 95%. Cooperate with omnidirectional infrared emission lamp to ensure no dead angle.

The BroadLink universal remote control RM Pro is packaged with a power adapter, USB power cord and BroadLink universal remote control RM Pro operation guide in addition to the host computer.

BroadLink universal remote control RM Pro has two indicators on the front, namely WIFI indicator and status indicator. The WIFI indicator light flashes at the first power on. When the device is connected incorrectly, it will flash intermittently for different times. If the connection is normal, the WIFI indicator turns off. The status indicator is mainly on during infrared learning.

The right side of the host is the device reset button, thermal sensor and Micro USB power interface. When the device has a problem or the configuration fails, long press the device reset key for more than 5 seconds until the WIFI indicator flashes.

Let's take a look at the internal structure of the BroadLink universal remote control RM Pro.

BroadLink universal remote control RM Pro supports not only infrared, but also 315, 433M RF signals. (At present, radio frequency signals are generally used for wireless control of intelligent doors, windows, curtains and other devices.) Therefore, the transmitter and receiver modules of these three modes are integrated inside.

This small black module, which is common on TVs or air conditioners, is the infrared receiving module. This is mainly for learning the receiving device of infrared remote control. The module on the right is 315M RF receiving module, which uses RXB22 superheterodyne wireless receiving module, and is a receiving module with high cost performance in ISM band.

The radio frequency transmission module of BroadLink universal remote control RM Pro uses two ASK/OOK transmission modules JMR-TX1. JMR-TX1 uses SAW stability (+- 75KHZ), stable operating frequency, and high transmission power. From the external antenna, it can be determined that the large diameter on the left is 315M, and the small diameter on the right is 433M.

BroadLink universal remote control RM Pro uses seven infrared light-emitting diodes to form a petal shape. To ensure the omnidirectional launch without dead angle, so that the control can be delivered accurately. The module below is 433M RF receiving module, which is also RXB22 superheterodyne wireless receiving module.

The circuit board covered by two serial numbers is the WIFI module, which is the bridge between the BroadLink universal remote control RM Pro and the mobile phone. WIFI antenna is built in the circuit board. The 88W8782 plus 88MC200 scheme is adopted, which is the same as the 88MC200-NAP2 master control used by Xiaomi smart socket.

The installation of the BroadLink universal remote control RM Pro is particularly simple, requiring only a simple configuration. It should be noted that infrared ray cannot penetrate the wall, so if it is used in multiple rooms, multiple hosts are required.

First, we need to download the app of the BroadLink universal remote control RM Pro, which is easy to control. You can download it on the official website or directly scan the QR code of the manual. After the download is completed, the BroadLink universal remote control RM Pro host can be powered on. At this time, the WIFI indicator light is flashing. Open the mobile phone APP easy control software. Enter the network of the phone and click Configure.

Here is a note: BroadLink universal remote control RM Pro does not support 5G WIFI at present. If the mobile phone is connected to a 5G signal, the device will fail to configure, and the WIFI indicator will flash continuously for 4 times.

At this time, it is necessary to reset the BroadLink universal remote control RM Pro device and connect the mobile phone WIFI to the 2.4G state. Re configure the device to succeed.

After the configuration is successful, click the corresponding device to enter the main control panel of the BroadLink universal remote control RM Pro. Here you can manage the APP, set the scene and add objects. Click the function key to add remote control, scene, device and view the device list.

There are two ways to add a remote control to the Easy Control APP. One is to add a remote control by customization, and define each key by learning. The other is to directly search and add, and enter the brand and model of the product to search. The addition and specific operation of the panel are not detailed here, but are detailed in the video tutorial.

BroadLink universal remote control RM Pro supports the scene function, which can realize one key control of multiple devices. For example, if we set the wake up scenario and click the Add command, we can select the control list and set related functions, and then continue to add in this way. The interval time can also be set in the middle. You can set multiple different scenes according to your preference, and you can easily set multiple sets with one key.

BroadLink universal remote control RM Pro also supports gesture control. As long as related gestures are bound, you can control the device without pressing a key. In addition, the BroadLink universal remote control RM Pro can also support third-party devices. For example, Xiaozhi Super Speaker can realize voice control equipment by entering Xiaozhi mobile phone APP, adding BroadLink universal remote control RM Pro, and binding according to prompts. However, currently, Xiaozhi can only recognize some simple voice controls, such as switching air conditioners, televisions, etc. For more control methods, you can only set them in Easy Control. For example, when the air conditioner is turned on in Easy Control, it is defined as TV channel plus. In this way, if you want to change the channel, you can tell Xiaozhi that the air conditioner is on.

In fact, the BroadLink universal remote control RM Pro has a lot of playability. On the way home, use your mobile phone to remotely turn on the air conditioner in your home, adjust the temperature to the most appropriate state, and bring you a real sense of home. The device itself is integrated with a temperature sensor, which can see the temperature change at any time. It not only stores multiple remote controls, but also is a key to open the door of smart home.
