Emoncms posting frequecy limitations?

Hi,

it’s a few days that I am pushing on an regular bases onto emoncms.org

Things are usually working fine, but sometimes I am receiving a Connenction Refused error.

This mean that the connection with emoncms.org is well established (no timeout or connection issues) but the server itself drops the established connection.

The calls are done through a Python client running on a Raspberry.

Here you can find a sample of the errors:

gen 29 17:15:25 raspberrypi start_hpsu_medium.sh[24623]: return request(‘get’, url, **kwargs)
gen 29 17:15:25 raspberrypi start_hpsu_medium.sh[24623]: File “/usr/lib/python3/dist-packages/requests/api.py”, line 49, in request
gen 29 17:15:25 raspberrypi start_hpsu_medium.sh[24623]: return session.request(method=method, url=url, **kwargs)

gen 29 17:15:25 raspberrypi start_hpsu_medium.sh[24623]: raise ConnectionError(err, request=request)
gen 29 17:15:25 raspberrypi start_hpsu_medium.sh[24623]: requests.exceptions.ConnectionError: (‘Connection aborted.’, ConnectionRefusedError(111, ‘Connection refused’))

I am pushing a set of 17 data pushed with a single emoncms.org API call every 10 seconds.

Is there any known limitations ?

I found only this statement:

Thanks in advance for the support !

Do you mean 17 data point (values) called every 10’s?

The emoncms API is limited to 10s data, @TrystanLea will have more technical info.

Yes exaclty.

In the meantime I removed garbage, reducing to 11 datapoints every 11
seconds.

I am trying to understood my heat pump detailed behaviour in order to
reduce defrost frequency that is always very High.

This is the reason of these numbers.
