Go to the Devices section and choose the device you want to configure. If you can not see the device ensure that you are in the correct organization.
IoT systems management (like the root directory in operating systems). It can be created only by Yosensi staff, and all clients using Yosensi Management Platform have one created for them by default. In case of any questions, you can find us at support@yosensi.io.

4. Proceed to the application by clicking its name on the list, then press the ‘≡’ button to add a node. Click ‘Add manually’ . Set the node’s ‘Name’ and ‘Description’ fields, and fill in ‘DEV EUI’ and ‘OTAA Key’ (otaa section – appkey). All device identifiers are provided by Yosensi Support when you order the nodes.

5. New nodes must be added in OTAA mode. Nodes can be switched to ABP mode after activation in the Yosensi Management Platform by changing the Node configuration. Click on the link in the ‘Node Name’ column. Go to the ‘KEYS’ tab and switch ‘LoRa Type’ from OTAA to ABP and fill in the blank spaces, then press update.
Extended documentation of the protocol can be found in the Payload description on our website. An example payload produced by YO Relay Switch is presented below with divisions for each measurement and marked with decoded values, whose interpretation is described in the Payload description.
