APIs​

Query API​

2.1.0 (9th July 2026)​

2.0.4 (10th February 2026)​

2.0.3 (6th February 2026)​

  • Fix to prevent blank/empty values in the data_controlAreaPathName column for records associated with a since deleted control area.

2.0.2 (24th December 2025)​

  • Fix to ensure that data associated with incomplete/undefined growth jobs are excluded on a per-tenant basis.

2.0.1 (11th September 2025)​

  • Fix to ensure that deviceId filter and data__deviceId column in result sets remain available for ChF data queries (type="chf").

2.0.0 (11th August 2025) Major version​

  • Breaking change The data__deviceId column has been removed from result sets for queries targeting indices data (i.e. type="indices") - See: GET /query/:queryId/result/download endpoint documentation. This necessary change supports multi-sensor monitoring of individual control areas. The data__deviceId column remains available for CHF-type data requests.
  • Breaking change The sensors filter is no longer supported in Query API requests due as it is no longer applicable following the removal of device from result sets - See: POST /query endpoint documentation.
  • Breaking change The controlAreas filter has been removed, and has been superceded by the controlAreaPathNames filter.

  • A new controlAreaPathName column is now available in result sets for both indices and CHF-type data requests, providing hierarchical mapping of measurement data to customer facility layout using a hash-delimited format (e.g., "Gardin#Glasshouse 1#Zone A#Small Bench"). See POST /query endpoint documentation for more information.

  • We have introduced a new controlAreaPathNames filter which provides enhanced flexibility and performance when wishing to limit query results to certain control areas and/or parent locations. This supercedes the now-deprecated controlAreas filter. See: POST /query endpoint documentation.

1.7.0 (7th July 2025)​

  • Automatic interpolation of periods with missing values within indices-type result sets is now supported and enabled by default. Interpolated records can be identified through the new data_isFilled column (where TRUE means an interpolated value has been used, and FALSE means interpolation was not required). Users can disable the inclusion of interpolated values via the new includeFilled filter property. See POST /query endpoint documentation for more information.
  • Introduced ISO-8601 compliant timestamp format for result sets (data__timestampIso column). See GET /query/:queryId/result/download endpoint documentation for more information.

1.6.1 (23rd April 2025)​

  • Fix to ensure job_id filter is correctly applied in all expected situations.

1.6.0 (4th February 2025)​

  • PPFD (Photosynthetic Photon Flux Density) index is now available to download via Query API. See documentation for the POST /query endpoint for more information.
  • Performance improvements through automatic exclusion of internal-diagnostics measurements from result sets.

1.5.0 (23rd October 2024)​

  • DPI (Daily photosythesis integral) and DLI (Daily light integral) indices are now available to download via Query API for selected license plans. See documentation for the POST /query endpoint for more information.

1.4.0 (3rd October 2024)​

  • Endpoint removed The GET /query/:queryId/result endpoint has been retired and is no longer available. Users should use the GET /query/:queryId/result/download endpoint, which supports single request, large-volume downloads.

1.3.0 (19th August 2024)​

  • Deprecation Notice The GET /query/:queryId/result endpoint has been marked as deprecated and is scheduled to be retired. Users should use the GET /query/:queryId/result/download endpoint, which supports single request, large-volume downloads. Update (3rd September 2024): This endpoint will be permanently unavailable after 3rd October 2024.

  • Index values in result sets now support the necessary 1dp precision.

  • Issue on POST /query endpoint preventing users from being able to provide an array of values for the controlArea filter has been fixed.
