Furthermore, and as the Article 29 Working Party stated, “end-users are rarely in a position to have access to the raw data that are registered by IoT devices. Clearly, they hold an immediate interest in the interpreted data than in the raw data that may not make sense to them. Yet, access to such data can prove useful for the end-users to understand what the device manufacturer can infer from it about them”. 
It is considered that the right to access cover both raw data and observed data about the user. However, under current developments, it does not seem to cover inferred data. This can cause detriment to users, as there is little options for them to gather insights of the most sensible data the system is processing about them.
Furthermore, the right to access is currently closely related to the right to data portability (see the “right to data portability” below, within this part on IoT).
