The motivation

IoT and smart home introduction

  • Internet of Things

  • Smart Home

Choosing the proper IoT devices, manual or existed?

  • Manual

    • ​Pros

      • ​It can control all of components. E.g. hardware and software.

      • It's for maker

    • Cons

      • ​It's hard and unfriendly for web or software developers.

  • Existed

    • ​Pros

      • ​It's the completed products.

      • It's friendly for web and software developers.

    • Cons

      • ​It cannot set some detailed setting for the products.

      • It's not full-control for the hardware.

      • Customized hardware specifications or behaviors are limited.

Choosing the proper IoT devices, manual or existed?
