What is the maximum number of devices a node can have?

A single ESP RainMaker node (physical device) can contain multiple devices (logical entities). The practical limit depends on:

  • Available memory on your chip
  • Number of parameters per device
  • Total MQTT payload size (must be under 128KB)

Typically, a node can support 5-10 devices comfortably. For complex product designs, consider memory and cloud communication implications.
