About Riiiver
Riiiver is an IoT platform that connects products and services, expanding their possibilities and providing a new kind of user experience. *Limited to Riiiver-compatible products and services. ~~Create and Use Your "iiideas"~~ With the Riiiver app, you can create and use functional items called "iiidea." Start by selecting one of the available iiideas that interests you and give it a try! ~~Make your “iiideas” come to life~~ You can create “iiidea” for the Riiiver platform. If you’ve ever wondered, “Wouldn’t it be great if I could do this?” or “Wouldn’t it be convenient to have that function?”, with Riiiver you can easily shape your ideas and make them a reality. ~~No special skills are needed!~~ Creating new functions with Riiiver is so easy. You don’t need to know anything about programming. All you have to do is put together a few functional modules (known as Pieces) in the app. Those with specialized knowledge (such as programming) can even create Pieces themselves. For more information on Piece development, please visit the Riiiver Developers website (https://developer.riiiver.com). ~~The structure of Riiiver~~ In Riiiver, functions are called “iiidea.” They are assembled from the three types of Pieces: Trigger, Service, and Action. To see a list of available Pieces, please check the following page: https://app.riiiver.com/piece_list/piece_list.html Riiiver is an open IoT platform service. As such, we plan to increase the number of compatible products in the future, so please stay tuned!
