JSON / HTTP(s) protocol can be treated as file-based M2M API protocol, where the NETIO device is a HTTP(s) server and the client downloads or uploads one text file document in the json format to control the NETIO power outputs (230V power sockets or IEC-320 power outlets 110/230V).
- If device support metering, the protocol also includes energy metering values.
- The JSON protocol must be enabled first in the WEB configuration of the respective device. For details, see the “NETIO WEB configuration” chapter.
- This protocol is HTTP(s) based. If you want use different port than is used for device web configuration, you can enable and use the M2M HTTP(s) port
- Username and password to access the file is hidden in the HTML header. There can be different username & password for the read and write access.
- With write (netio.json file upload by http post) the device send you back the current (updated) json answer content in the same structure as the netio.json file.

AN21: JSON HTTP(S) protocol to control NETIO 110/230V power sockets (3x REST API)
The AN21 Application Note shows how to access measurements and control electrical sockets on a NETIO 4x device from third-party applications using the JSON protocol. AN21 demonstrates several different ways to control NETIO power sockets by transferring a netio.json file over http. The first method uses the “Device HTTP(s) File Upload” tool in the device’s web interface. The second method transfers the JSON file using a Chrome browser extension. The third method uses CURL (command-line tool) to transfer files over http.
