Allow setting min/max range for target temperatures

[composerkaumann]

Cooper & Hunter CH-SI2FTXAM2S-WP has a temperature range that starts at 8 degrees Celsius (for keeping unused premises above freezing temperature in winter).
With every Gree AC component update it is necessary to edit the .py file and change the temperature range.
Could that be avoided with future updates?

Can you share a bit more information? What kind of edits are you making? And did you see the 8 degree's switch on the device in the settings?

I could last try the device in July with component ver 2.x.x. I will set it up again with v. 3 mid-september when I am at the location and can turn the fuse on again. Will then report back.
No I did not see 8 degree switch. My device can go in down to 8C gradually in heating mode and so far with every update I have just changed the lower temperature limit from 16 to 8 Celsius. Sometimes I keep the device on 8 sometimes 10 or 12 degrees. This way the unit is fully operational, can select any temperature between 8 an 30 C

[RobHofmann]

Let me know when you tested it.

[composerkaumann]

Tested it. v. 3.2.2
8 degrees heat switch is not working. Had to change the lower temp in constants file.
This pump has a heating range from 8 to 30 C in 1 degree steps throughout the range.
So with every update I have to log in to samba share and change the lower value. I don't bother with fahrenheit at all, not in use here.

@domialex can this be another coordinator logic challenge?

[domialex]

For this issue it's probably easier to add a configuration setting for min/max temps, with default values.
You should probably change the title to something like "Allow setting min/max range for target temperatures".
As for the coordinator, with the latest changes, I don't think it's needed anymore.

[RobHofmann]

Modified the title of this issue. Clear.

The same issue, my AC (FUNAI RAC-I-ON30HP.D01/S) operates heat in HA from +16, but ewpe smart does it from +8.

[GlebKondratyev]

it is necessary to edit the .py file

what file is it?

[composerkaumann]

const.py

MIN_TEMP_C = 8
