Buttons not available

[palengh]

Hi, there, and a big thank you to Åke (@astrandb) for this integration!

All sensors seems to work, but I cannot get the two buttons to become available (listed unavailable).
Does the machine need to be in a special state for it to be available in HA?

Both button.washing_machine_start and button.washing_machine_stop unavailable

It's a Miele API problem. The buttons used to work fine with my washer-dryer, but not anymore. Either Miele has changed their API or something broke again. Unfortunately, they document neither.
