Using Mosquitto Bridge
One of the easiest way to forward your existing devices' data to the Csip.io platform is to setup a Mosquitto bridge locally and forward it to the Csip.io broker. You can achieve that as shown below:
In the example above we show how a local Mosquitto broker can be used as a bridge to send data to the Connio platform.
Here, {DeviceID}, {DeviceKeyID}, and {DeviceKeySecret} are belong to the virtual device created on the Connio platform. The physical device writes into mydevice/events topic locally and the bridge forwards the payload to connio/data/out/devices/{DeviceID}/methods/processMessage topic on the Connio broker which is linked to a method called processMessage of this virtual device.
Please see section "Configuring Bridges" of the Mosquitto configuration.
