fail to set target temperature after HA upgrade to 2024.8

[eddysteurs]

*After upgrading HA to 2024.8 it fails to set the target temperature to different value.
On the HA temperature card (and climate entity) it does change the value but it does not flow to the actual device.
So on next refresh from all sensors it is back on the original value.
When setting it via the temperature card (or an automation) is gives error
'Failed to perform the action climate/set_temperature. '<' not supported between instances of 'float' and 'NoneType''

Probably related to home-assistant/core#123612

Here's my traceback:

no I dont think it is the same problem as my temperature I want to set is well within min and max temp range.
I guess it might be cause (link to HA update) because I do not get all the correct parameters in the climate entity via de aquatemp integration for my phnix (hitemp wifi) heatpump. Since many month I override them via an automation (min, max temp, state and target temperature) with the appropriate aquatemp sensors (or attribute) and this allowed me to change the target temp via the climate device but since HA 2024.8 it now gives this error mentioned above, is this something you can fix in aquatemp integration?

I have the same issue. Does anyone have a solution for this?

I changed config\custom_components\aqua_temp\climate.py lines 100 and 101 from:
self._attr_min_temp = minimum_temperature
and
self._attr_max_temp = maximum_temperature
to
self._attr_min_temp = float(38)
and
self._attr_max_temp = float(60)
That fixed the issue for me. I think for my heater it was trying to set the minimum and maximum temps to None, and Home Assistant was not happy about that.
