Idea to design script programmable controller based on ESP8266

In the application field of factory automation, we chose a 5G+2.4G high-performance Wi-Fi module to go with the MCU to design a set of wireless input/output controller;
Many users commented that the Wi-Fi module is too expensive, and it is true that, for general non-reliability, ease of use requires slightly lower occasions, it is entirely possible to use cheaper Wi-Fi modules, such as ESP8266;
Recently we are ready to design a very cost-effective remote controller with built-in script programming web page;
The main controller is an ESP8266-07S, which provides two digital inputs with NPN/dry contact, and two 10A relay inputs;
The material cost of a single controller is about 20RMB or less, and the selling price of the web sales can be up to 30RMB/set if you only make a profit;

I did a brief survey, and there are very many similar remote relays for sale online, such as the remote relays from exlink, which sell for a few tens of RMB;

In contrast, the selling point of our planned controller is to provide input interfaces, which can be used to realize the combination of input and output and the logic design of timing through the script programming of the built-in webpage to realize the functions of automatic control, timing control and so on;

Moreover, we provide self-designed cloud platform and API interface for the controller to access to realize remote control, script programming program management, sharing, assistance and other Internet + functions;
