For example, a logger that measures only the temperature, performs a measurement every 3 minutes, sends data every 3 hours, and four times a month sends data because of exceeding the thresholds, consumes 60.5 kB per month. The same settings for a temperature and humidity logger will require 89.3 KB of data per month. It is safe to assume that the monthly data usage of a single device with three slots is 150 kB. This includes firmware updates and configuration changes. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.efento.io/nb-iot-loggers/data-usage.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
