How can PRTG's API retrieve historical data for multiple sensors and channels in a single API call?

Can PRTG's API retrieve historical data for multiple sensors and channels in a single API call?

No, PRTG's current API requires you to query each sensor individually for historical data. It does not support fetching data for multiple sensors or channels in a single API call. You must aggregate results from separate queries to compile data for temperature, humidity, or other parameters across multiple sensors. PRTG currently prioritizes other features, so these API enhancements are unlikely in the near future.
