Important:
  • When connecting to the Apreia network, disable mobile data or accept 'use without internet' when your phone asks.
  • Each Raspberry Pi automatically generates a unique network name (Apreia_XXXX) based on its hardware, so multiple units can be used in the same room without conflicts.
  • RAW photos continue to be saved to the camera's memory card as normal.
