Minimum push interval
« on: May 22, 2020, 12:37:39 PM »
Can someone remind me please: What's the minimum interval that can be set for a Nano push HTTP Get. It looks like 5 secs - is that right? So there's no way of pushing eg wind data from each individual new LOOP as it's received, which would be roughly every 2.5 secs. (I know you could presumably get this as the full binary packet via passthrough, but I'm asking specifically about push)

correct 5 seconds under a manual GET http request

OK thanks. And just in case I haven't asked quite the right question: So there's no way of getting at the totality of all the wind data in the stream of LOOP packets  via push other than to use passthrough (which slightly defeats the value of using Nano). It's just a bit frustrating - 5 secs is short and almost there but still 50% of the wind gust values would be missed. But maybe the CPU in Nano isn't quite powerful enough to cope with making every single LOOP available via Push?

think Boris has touched on this in the past , but your right there is the remote chance in a display/website output but if you need max value for last minute that can be done so its not missed in a display or external storage.
example
[wind0wind-max1:-]

will give you max last minute

the five second limitation is only apparent in sending data to an external http doesn't effect the data received via the console

OK, thanks again. But the application I have in mind calls for real-time wind data from multiple anemometers to be forwarded to a central computer for comparison/processing, so some reliable form of highly granular export is essential. It may be that Weatherlink Live is the solution here and one unit could potentially receive the data from all anemometers rather than one console/Nano per anemometer.

Sorry I know this is a niche case and not of general interest here but just trying to spin up a solution for an ongoing project.
