The communication between the sensor and the server is encrypted. Read more about the encryption or see a Python code example.

A server must implement three endpoints:

• update - Intended to be used to associate a sensor with a user account, used by the config app to test the connection.
• config_show - Used by the sensor to retrieve its configuration, e.g. which sensors are enabled, how often to measure and how often to transmit stored readings.
• readings_add - Used by the sensor to transmit its stored readings.

1. Press the sensor's button for at least 3 seconds, until the LED turns and stays orange.
2. Connect to the sensor's config Wi-Fi and open the configuration page in your browser http://172.29.0.1/ to see if the connection works.
3. Then change the URL in your browser's address bar to http://172.29.0.1/sos_config?host=api.example.com&port=8005 with your desired host and port. The host can be a hostname or an IPv4 address.
4. Goto http://172.29.0.1/ and enter the WIFI credentials and any user credentials (just enter anything that looks valid, these are not used, but required for the connection to be setup) and click 'connect'.

To get your current configuration visit http://172.29.0.1/sos_config.

This setting is lost after a factory reset.

Write an e-mail to [email protected] and mention the MAC addresses of your sensors. Within a few days we will reply with the symmetric keys and calibration data.
