Error 400 in log

[krusta4711]

Hi,

I'm using hcpy (in a docker container) since a week. Everything seems to work fine. I see state changes reflected to my sensors and I can start programs. All sensors are available. Nevertheless I do have a lot of messages starting with "dishwasher updating {"error": 400". It seems I get them after every changes. Is that intended?

I searched in hcpy Github repository and the 400 seems not to come from hcpy, but seems to be something that is send by the dishwasher. I also see the error field in MQTT. Is it normal behavior?

There are a number of different Auth mechanisms between different versions of the devices,. We don't replicate this accurately yet so quite often try and call a function that doesn't exist on some devices. So we tend to get an error returned. We don't really filter any output from the device so this error comes through but can be ignored in most cases.

It can be handy to check the error if you are trying to send commands to the device and it's not working for some reason, so its left in for debugging.
