Failed to fetch data

[ernsttanaka]

Hi trying your new Duco integration:

I am getting the following error in the logs:

1. Are you using a ducobox connectivity board?
2. The integration is trying to connect over port 80 (http) but the connectivity board can only be reached over port 443 (https). Have you added the box manually or automatically through zeroconf / mDNS?

[ernsttanaka]

Yes, I have a duco energy premium with a connectivity board. the reference for port=80 comes from the integration. the Duco was self discovered by HA, I only added it to an area.

This is a working url if and when I type it directly in safari: https://192.168.4.89/info/nodes

here is another error I am also seeing the log:

This error originated from a custom integration.

when I go directly to this address in Safari I get:

I've made some adjustments to the code and enabled some extra debugging. Could you try updating and report back if it does or doesn't work? If it doesn't: please enable debugging for this plugin and send me the logs.

[ernsttanaka]

appreciate the help, it now works - most entities are being populated.

The Duco integration has been split up in 8 devices and which collectively have 38 entities. The box, every CO2 sensor and the BOX RH have become a device (in my case a total of 8.

After a few minutes it stops working;

Initially I get a warning:

Logger: py.warnings Source: custom_components/ducobox-connectivity-board/sensor.py:420 integration: ducobox-connectivity-board First occurred: 3:24:25 PM (6 occurrences) Last logged: 3:26:41 PM

Which then turns into a error:

[Sikerdebaard]

The InsecureRequestWarning is unlikely to be the culprit here. That's more related to the self-signed certificate that the ducobox connectivity board uses. The root library, ducopy, does not have this issue as it uses certificate pinning to prevent this error. But I haven't gotten certificate pinning working yet from home assistant. HA seems to override some ssl/tls settings. In any case, it is something to fix later. It can wait.

The error 503 happens on my connectivity board as well. I am not sure why it does that. But after a few minutes it works again. Can you verify that it is picking up samples again after a few minutes in your installation? Or is it permanently dysfunctional after this error?

another "find" in the logs

on tweeker I read that 503 comes when we poll too often in a time span. No indication of time span or freq what's regarded too Often.

[ernsttanaka]

good morning The reading is still intermitted. See the graph from last nights co2 measures on one of my sensors. I have no good indication what this causes. I have reduced the scanning to 5min.

[ernsttanaka]

Installed the lasted version. Still issues with intermittent data. I set the scan to 300sec that improves the situation a little
