Product Overview

2.1.Project background
Under the Illumicare Group Limited’s entrustment, Wanliankeju has developed a regional control system (also known as astronomical clock system) based on the 2.4 GHz frequency without protocol stack, that is, the first generation of Merlin..(2) The The system adopts three components: MASTER SLAVE and RX. Timing functions (including sunrise and sunset) are controlled by MASTER. Since sunrise and sunset need to be calculated according to the location of the user, the MASTER built-in GPS module makes the product cost higher.
With the progress of technology, smartphones gradually enter the hands of ordinary users, the Internet of things platform has become mature. Since smartphones have built-in GPS modules and the integration of smartphones and Internet of things platforms can provide a more diverse operation and a good user experience, MASTER is no longer necessary. Therefore, the development of a new generation of Merlin products has certain feasibility.
At the same time, because the product access to the Internet of things platform needs to pass through the Internet, and outdoor products are not suitable for laying network lines, the communication mode based on Wi-Fi is more suitable.
On the other hand, because the communication distance of the Wi-Fi is limited (the effective distance is only ten meters to tens of meters), Illumicare Group Limited hopes that the HUB can make up for a certain lack, so it is required that the communication distance can be reached farther. Through investigation, the R & D team decided to use LoRa technology to replace the original no-negotiation stack 2.4 GHz, so that the communication distance can reach thousands of meters.
The new generation of Merlin products is a set of regional control systems using Wi-Fi and LoRa dual communication mode. Merlin-WiFi. is the product interior.
2.2.Merlin-WiFi is what
The area control system composed of smartphone end APP, RX equipment, SLAVE remote control, and Internet of things platform is mainly used for low voltage lighting in other outdoor gardens. Support APP and SLAVE remote control to RX switch control.

• APP: The application running in the smartphone can control its switch to the RX device by WiFi, and can set various timing modes, scenes, and automatic opening. tuyaAPP can be downloaded free of charge through the application market such as Apple APP Store or Google Play.

• SLAVE Remote control : The maximum unshielded communication distance is 3000 feet through the LoRa operation of RX equipment. It’s a 2 AAA battery power supply. SLAVE based on area control mode, one SLAVE supports 6 regions, each region can bind multiple RX devices. RX equipment in the same area is on or off at the same time. SLAVE also supports the operation of all devices in all regions. SLAVE includes a 2-digit digital tube display, an area switch button, an open button, and a closed button. There is a backlight under the key, when any key is pressed, light up, release and extinguish.

• RX: Terminal controlled equipment, using low-voltage AC power supply, placed in an outdoor garden. The input end is connected with the low voltage power supply source, and the output end is connected with the lighting lamp or the electrical appliance. Input and output are reserved for a certain length of wire to facilitate installation. To control its turn on or off by APP or SLAVE. Support lower temperature (-30 degrees Celsius) and meet certain waterproof requirements. RX contains a RESET key, a power indicator, an operating indicator, and a rod-shaped LoRa antenna.

• HUB: Wi-Fi network and LoRa network adapter. Used to connect RX, manage and control RX. You can connect to the Internet of things platform and control RX timing and instant switches through APP or other audio terminal devices.

• Internet of things platform: The Internet of things platform is used to manage RX equipment and authenticate the RX safely. End-users can manage and control RX through the platform, and can also set up scene automation. Operations and maintenance personnel can use the data analysis and operation management functions provided by them. This system uses the third-party graffiti intelligent platform. APP and RX equipment are connected to the platform for interconnection. A third-party intelligent speaker can be purchased to access the platform to voice control RX equipment.
  2.2.Product architecture
  2.3.Product Applicable Population

•  General users: villa residents living in North America, their outdoor gardens are larger, usually equipped with multiple garden lighting and electrical appliances. They want to be able to control multiple devices at the same time, preferably timing, especially at sunset and sunrise. Because of the large outdoor range, they also hope that the remote control distance can be as far as possible. It is best to adjust the time easily by mobile phone control.

• Illumicare Group staff: as providers of equipment, they want to track the products sold and know the status and use of the products so that they can respond in time when there is a problem. At the same time, they hope to be able to plan future sales focus according to the product usage distribution area.

• KOJ operator: as the operator, I hope to know the use of the equipment at any time, so that I can respond to the problem in time.

E. APP start searching;
F. After APP successfully searches the device, the system will automatically register the device to the Internet of things platform and initialize the device;
G. HUB the device is initialized, the right WiFi lamp is in a long state; if the connection fails, the right WiFi lamp is extinguished. APP interface displays an icon (which may take a long time to display), click modifies the name, and then use it normally.
4.3.5.2.To establish an association between SLAVE area and RX equipment
The user must establish an association (i.e. binding) between the SLAVE area and the RX device to control the device through the SLAVE. Mainstream follows:
A. Connect the RX device to input power supply, power supply lights long;
B. A user switches SLAVE to a specified area;
C. The user presses and immediately loosens the RX device key, RX enters the SLAVE to be bound state, at this time RX the red indicator light will flash twice;
D. A user presses a SLAVE open or close key;
E. When the binding is successful, the RX operation indicator flashes three times. If the binding fails, the RX operation indicator lights will go out.
4.3.5.3. To establish SLAVE association with HUB equipment
The user must establish an association (i.e. binding) between the SLAVE and the HUB device in order to pass the SLAVE address to the HUB device so that the RX device bound to the device can be controlled. Mainstream follows
A. A user connected to the HUB equipment power supply, power lights long light;
B. HUB short press button, Hub middle-STATUS lights flicker 2 times;
C. SLAVE user switches to any area;
D. A user presses the SLAVE open or close key;
