No preset modes for climate entity

Configuration Matter/Thread
1

I have the matter thermostate 7iE from warmup. But in the climate entity, there are no preset_modes and so the set_preset_mode action does not work.
This means that if I programmatically set a temperature, I cannot return to the normal schedule.
Is this a limitation of matter or did the warmup developers forget it?

Also, I found that there is not hvac_mode "auto", only "heat" and "off". So one cannot check if it is running with a fixed temp or on a schedule. But this seems to be a bug in the device.

When the WARMUP thermostat is connected via Matter, I'm fairly certain the presets are most likely not mapped. You may need to explore using a Generic Thermostat and Automations

There is a custom integration via HACs, but I did not review if it's current.

This means I cannot switch between fixed temperature mode and schedule program mode.
