Opinum usage limits
If you have a specific use case that you need Opinum to support beyond these limits, please contact our support team firstname.lastname@example.org.
Opinum DataHub supports the following browsers:
- Microsoft Edge
Opinum Data hub does not support any version of Internet Explorer.
The mobile app is available for Android (4.0.3 and up) and Iphone, on mobile and tablets.
In 2020 only the Android versions 6.0.0 and up will be supported. The lowest versions won't be compatible anymore with the technology.
File size limits
The maximum upload file size is 1 megabyte, for all files except Opinum Standard Data File format, of any extension, uploaded by any method in Opinum.
The maximum upload file size is 20 megabytes, for Opinum Standard data File, uploaded by any method in Opinum.
Above this size Opinum can't guarantee than the file will be correctly ingested and processed.
A maximum of 1 000 connections per day are allowed on the FTP. Above 1 000 connections a warning will be sent to the client to decrease the number of connections under 1 000 per day. If the connections don't decrease after 48 hours, the access to the FTP will be suspended on the account, until the necessary is done.
If you need more than 1 000 connections per day, you should send your data by HTTP on the API. Learn more about Opinum API
The files uploaded on the FTP are ingested at the frequency of 1 file every 2 seconds. For example, if 1 000 files are uploaded at the same time, they will be ingested into Opisense in 33 minutes.
Any massive upload that exceeds the usual account data ingestion must be monitored by Opinum (e.g. history loading, account reset, etc.). A request must first be addressed to email@example.com.
Once your request is approved, the files must be uploaded on the FTP under those conditions:
- A new folder named .toprocess should be created
- The folder can contain a maximum of 100 000 files.
- If more than 100 000 files are to be processed, then a second folder named .toprocess2 should be created at the root as well (especially no sub-folders).
The minimum granularity for receiving a datapoint is 1 per minute.
The maximum duration of the computation of a calculated variable is 20 seconds.
If the calculation is so complex that it needs more than 20 seconds, the calculated variables may be deactivated by Opinum. Our support team will contact you to find a solution to compute your calculations in the respect of the system.
