HP2551 Weather Station HTTP interval

[water01]

My interval for sending out the HTTP message to CumulusMX is set to 16 seconds (the minimum setting the HP2551 firmware will let me set) but Cumulus MX does not get a station update every 16 seconds. It seems quite variable as to when it updates but it is a minimum of 30 seconds and sometimes at least 50 seconds to a minute.

My test system on my Synology NAS is getting data from a GW1100 gateway which is fed from the HP2551 and it has the upload setting set to 5 seconds and the station update happens every 10 seconds without fail, not variable at all.

Any reason for this or is it just the way the Ecowitt HTTP protocol works.

I seem to recall from the wxforum that the HP2551 is low powered compute wise and just the uploads when it has a spare moment! (kinda sort of, paraphrasing there) Particularly if it has multiple uploads configured.

This has been discussed before:

and I think the conclusion was: it is the Ecowitt.
