Failed to set up: Import error

[rudgej]

I have just updated to 2025 2.2. As far as I know it was working before this update but I did not check

I now have failed to set up - import error showing and the logs are as below.

Log details (ERROR)

Logger: homeassistant.config_entries
Source: config_entries.py:606
First occurred: 11:03:03 (1 occurrences)
Last logged: 11:03:03

Error importing platform config_flow from integration heatmiserneo to set up heatmiserneo configuration entry: cannot import name 'HVAC_MODE_COOL' from 'homeassistant.components.climate.const' (/usr/src/homeassistant/homeassistant/components/climate/const.py)

If anyone could let me know the fix I would appreciate it.

The system is heat miser under floor heating.

Thanks

FYI looks similar in root cause to #134636

I got it working using a slight variation of the changes to fix the other issue. Here's what I did, using the terminal add-on.

1. Change directory to ./homeassistant/custom_components/smartthinq_sensors/
2. Make a copy of binary_sensor.py
3. Open binary_sensor.py with your favorite editor
4. Navigate to the section that starts with the line "from homeassistant.components.binary_sensor import"
5. Inside the parentheses, add the following text

DOMAIN,
BinarySensorDeviceClass,
BinarySensorEntity,

5. Save the file.

6. Now make a copy of sensor.py

7. Open sensor.py with your favorite editor

8. Navigate to area that has several lines like "from homeassistant.const import"

9. Inside the parenthesis, add the line:

UnitOfTemperature,

10. Save the file.

11. As with the other two files, make a backup of the file climate.py and open it in your editor

12. Add the following lines to the section "from homeassistant.components.climate.const import"

DOMAIN,
HVACMode,
SUPPORT_TARGET_TEMPERATURE,

13. Save the file.

14. Back up const.py and open it in your editor. Add the following lines at the beginning of the file.

from datetime import timedelta

from homeassistant.components.climate.const import HVACMode

CLIMATE_SUPPORTED_MODES = [HVACMode.HEAT, HVACMode.OFF]
UPDATE_INTERVAL = timedelta(seconds=30)

15. Save the file and restart Home Assistant
    This worked for me. Hope it helps.
