Best Practice 21.2 – Implement and configure telemetry to reduce data transfer costs

Matching the precision of telemetry data, such as number of decimal places, to the precision of the required calculation can help address both the overall message size and the precision of calculations.

Recommendation 21.2.1 – Reduce string lengths and decimal precision where feasible

  • For example, strings sent regularly such as "POWER" or "CHARGE" could be reduced to "P" or "C" strings. Similarly, decimal values such as “21.25” or “71.86” could be reduced to “21” or “72” if the additional precision is not required for the application. This is common in room temperature readings where precision beyond is whole number is rarely required. Across many millions of messages, the savings from removing a few letters can make a significant difference in message size and cost.
