request_hvac_update failed - vaillant integration unavailable about vaillant-component

[thomasgermain]

Hello,

so first what do you mean by the integration is offline ? You don't have any new data coming in ? If it's the case, do you have any other errors ? Because the integration is refreshing the data every 2 minutes, so if you don't have any new data for 1 day, you should have plenty of errors.

I have something in my todo list to fix the JSONDecodeError, sometimes, it seems the API doesn't return json. I'm still wondering how I can do that.

You could have the request_hvac_update is done too often if you open the app and just after the HA integration is also calling the request_hvac_update . So if you only had the warning once, I would recommend to keep it every 1h.

Yes, the integration is getting data at HA starting (like any other integration actually).

By the way, if you are developing, you should use HA inside docker https://www.home-assistant.io/docs/installation/docker/. I'm suing that (so my "production" HA is actually never restart expect on electricity failure or update).

after restart - thats the very first message:

2020-10-06 22:16:43 ERROR (MainThread) [custom_components.vaillant.hub] Unable to fetch data from vaillant, API says: {'errorCode': 'FACILITY_NOT_ONLINE'}, status: 409

pymultimatic.api.error.ApiError: Cannot get https://smart.vaillant.com/mobile/api/v4/facilities/xxxxx/systemcontrol/v1

and thats it - in hass the all entities just read "unavailable".
I also just checked the logs and the automation for request_hvac_update does not get triggered directly after each restart - so my worry was arbitrary.

/edit: and of course - while writing this and restarting home-assistant once again - everything went back to normal.
maybe vaillant just put me on a temporary ban and the update once every hour somehow prolonged it .. or I don't know ..

yeah, of course 😛 (it only happens to me).

Actually, the vaillant API is quite unstable, I often receive an empty message, or an error "REPORT_DOES_NOT_EXIST", "FACILITY_NOT_ONLINE" or connection timeout (specially during the night). This is why I put extra effort for the integration to be able to recover from these errors, so you don't have to restart HA.

I don't think there is some kind of ban, are you using a dedicated user for HA ?

[h4de5]

I thought so. yes - the HA integration uses a different account than my mobile phone - which I use anyways just to check if the API is really offline or my HA setup somehow messed up again ;)

still strange - i restartet HA pretty often yesterday, but at least between 10pm and just before I didn't any data in the log.

but again thanks for the clearification.
