String values can provide additional information to your dots. As a basic example, let's suppose you’re deploying a weather station that provides you the weather status as a string value, e.g. "cloudy". In order to receive that string in your Connected Sensors account, the weather status must be sent in the context of the dot.

curl -X POST 'https://api.connectedsensors.com/api/v1.6/devices/my-new-device' 
-H "X-Auth-Token: BBFF-Rfcgaxns6HlVb155WA0RhSY85xNDmB" 
-H "Content-Type: application/json" 
-d '{"weather":{"value": 1, "context":{"weather-status": "sunny"}}}'
