What are the differences between OCPP and Tuya protocols?

OCPP is an open communication protocol between Charging Stations and Charging Station Management Systems (CSMS). It is widely adopted globally (except in China).

Meanwhile, the Tuya protocol is a private communication protocol based on the Tuya IoT model used between Tuya devices and the Tuya cloud. The protocol is based on a more intuitive and universal IoT model, and it provides a rich and mature SDK as well as IDE, greatly lowering the barrier to smart device development for developers. Tuya cloud and the protocol correspond to a global connection of hundreds of millions of devices, with tens of billions of device requests daily. After rigorous testing, it can provide a stable and reliable user experience to people around the world, complying with local security and privacy regulations.

It can be seen that both OCPP and the Tuya protocol are communications from devices to the cloud, and they are interchangeable. Due to the security and reliability of the Tuya protocol and its extremely low development threshold, many developers have adapted the Tuya protocol, providing PBT home charging stations to users at home and abroad in bulk. Developers only need to integrate once, and then they can choose any Tuya module, enabling the device to support various protocols (Wi-Fi, Bluetooth, Zigbee, LTE Cat.1, Cat.4, Cat.m, NB-IoT, etc.).

Tuya cloud provides Tuya devices with a wealth of capabilities, such as OTA upgrades, multi-language support for panels, third-party voice control, customized message push, and so on.
