[FAQ] API Data History Limitation and Archives

To properly handle the large amount of our client’s data without compromising the global performance, Wattsense stores data in two different locations, in a database that we qualify as hot, i.e. data is immediately accessible via the API, and is archived in a cold storage location. Data’s lifecycle is as follow:

  • When data is received it’s available using the List Device Properties Values API
  • The next day, the data can be recovered using the Request An Archive API
  • 30 days after having received the data, it is no longer accessible via the immediate access API, but is still available via the archive retrieval one
  • At the end of your device subscription, you are offered a delay of 6 months to download your archives, before they are permanently removed
