wallthermostat missing method 'get_programmed_temp_at'

[S-E-B-123]

Hello
when I use the Max! Integration in Homeassistant with my Max! Use WallThermostat and switch e.g. from "off" to "auto", then I get the following error:

The object 'MaxWallThermostat' does not have an attribute 'get_programmed_temp_at'

Is there a reason why the MaxWallThermostat doesn't support this? Or is there a chance to implement "get_programmed_temp_at" in your code?

Thank you
