Dweet Pro Library SL

This is an unofficial library for use with the dweet.io and dweetpro.io service. It’s developed to use with the main features as sending and receiving dweets. The library supports a secure connection between the service and the PLC controller. TLS encrypts all traffic. The dweet service also offers the opportunity to protect your “Thing” with a secret key.
Without purchasing a license (just download), the Dweet Library SL runs for 30 minutes without functional limitations and disconnects automatically (demo).

With this library, you can start your IoT Project within minutes. You can send your data from the field to the cloud or request it. There is no 3rd Party software installation required. The communication is directly established with the Dweet Pro or Dweet Service; both are acting as a cloud gateway.

Each PLC needs to be registered as a “Thing”. So it’s possible to communicate with different “Things”, no matter if it’s a PLC or other device. Data is exchanged in the open-standard format JSON. So you can integrate the data easily to existing software products.

The product is coming along with a detailed documentation and a Quick-start guide (https://pfaendergmbh.atlassian.net/wiki/spaces/Dweet/overview). So you can start to use this library together with the dweet service within a really short time. The library can be tested without any fees!
