ValueError for target temperature in dehumidificator mode

[KaiRo-at]

I did set my A/C to dehumidificator mode (mode = 2), and then reading the target_temperature causes a ValueError, see the following snippet:

  File "/path/to/myproject/venv/lib/python3.8/site-packages/daikinapi/daikinapi.py", line 182, in target_temperature
    return float(self._get_control()["stemp"])
ValueError: could not convert string to float: 'M'

This is in debug output BTW:

And FWIW, it's similar in mode 6 (FAN), with this output:

And then, I can't get set any other mode any more from daikinapi, I guess because stemp and maybe shum are invalid for those modes but we send them together with the new mode, see also the following output:

Compare to that what gets done when I switch from auto (set via the remote control) to cool via daikinapi:

Sorry for another comment, but interestingly, switching from mode 2 (dehumificator) to mode 3 (cool) seems to work, it only gets stuck in fan mode, so it seems like 'M' is valid for set_control_info:

(And FWIW, 25°C was the stemp before I switched to mode 2.)

Hello @KaiRo-at,

Thanks for reporting, as I don't use dehumidifier mode (and not too much testing) I did not catch this. Would you be interested to submit a pull request?

Cheers, Aarno

Thanks for reporting, as I don't use dehumidifier mode (and not too much testing) I did not catch this. Would you be interested to submit a pull request?

I also usually do not use it but when my setup was new, I played around a bit to see how things are working - and I had a wall in my office that was wet from a minor water damage so I did run the dehumidifer mode for a number of nights to help dry that up.

Not sure how much time I'll have to look into a potential pull request as I'm short on time in general, but I'll keep this marked as something to look into.

[arska]

Cool, thanks, so leaving this issue open for now :)

[Mausy5043]

I've run into this problem myself some time ago too. * When switched to fan-mode the temperature target becomes '--' * When switched to drying mode the temperature target becomes 'M'

I solved this application-side by replacing the temperature target by the actual temperature in case of a ValueError (ref). Of course this can also be solved API-side in a similar way.

[Mausy5043]

#18 proposes a change to the API that would fix this issue API-side but may have impact on applications that are expecting a numerical result.
