Switching from heat_cool to fan or dry results in fault - Failed to call service climate/set_hvac_mode. '>=' not supported between instances of 'NoneType' and 'float'

[dhi20]

Hi, When changing from heat_cool to dry or fan the following error results. It seems to be a result of the target temperature being null when in heat_cool mode.

I am able to get into fan and dry mode if I first move from heat_cool to either cool or heat modes.

I've got the same issue. This happens both when the mode change is triggered manually (by the lovelace card) as well as when the change is by a schedule or automation.

This is an extremely frustrating change as it pretty much broke several key automations for my home system.

@dhi20 @TriskelionTech I have written an update which I hope will fix this issue. Could you please check and let me know if the newest version fixes the issue for you?

[david-kalbermatten]

Seems to work as intended. Confirmed it myself while testing for #65
