AxiosError: Request failed with status code 400

[thoeckerde]

Hello,

I use the HmIP-eTRV-B-2 R4M thermostats. When I change the setTemperature status for one thermostat, I have been getting the message "Request error: AxiosError: Request failed with status code 400" in the log for some time.
Sometimes the thermostat switches to the set temperature anyway, but sometimes not.

Perhaps the error message relates to issue 536?

Good question ... error 400 is "bad request" ... whatever that means ... so ... when does it work? When not? Please try to test that out and provide such details, maybe we find a reason

I analysed it in more detail for a month. I currently assume that the data is always transmitted correctly, even if the response is always error 400. If the temperature is not being transmitted correctly to the cloud, I suspect it's more likely to be due to internet interruptions, which we've unfortunately had a lot of here recently. But I will keep an eye on it.

Same here as described by thoeckerde
