Our Nest Thermostat is currently set to heat at a single target temperature; starting today, the UI began showing this:

Although this data is correct (in that min and max targets are, indeed, null):

...shouldn't the platform show the target temperature?
EDIT: had an incorrect second screenshot.
Which version of Home Assistant are you using?
@balloob 0.66.0 (sorry, should have included that).
The only anecdotal info I can give: it seemed to happen this morning when I randomly tried the climate.turn_off and climate.turn_on service calls. Can't imagine that's a problem, but FYI.
So it is caused by #1037. But the bug is in the backend: we should not include a target temp range if operation mode is set to heat.
And the backend bug is related to https://github.com/home-assistant/architecture/issues/22
@c727 do you think that we should include temporary null checks for attributes?
Hmz. Someone else has to fix it please, currently not at home
Done
I also have this bug. But not only with the nulls but also extra controls are now shown. Wasn't the case in 0.65

We have the same issue with ecobee climate
For me the fix in 0.66.1 didn't work Still the same. Mysensors HVAC component

Have you done a hard refresh of the browser page? Ctrl + shift + r in chrome.
@MartinHjelmare is right on the money: a hard refresh does the trick!

OK nulls are gone. But the problem with several temp controls is still there

It might be related to supported features. I think we need to make those conditional now in the mysensors platform. I think this is a separate issue.
There's two approaches to this. Either change supported features, or disable/hide controls based on the state.
I would prefer the latter (like we do with the light controls) as supported features is a given for a device, and should not change based on its state/operation mode...
Mysensors is a bit special as the features depends on the sketch the user writes. We have to support different sketches. It's comparable to different types of devices.
@MartinHjelmare Shall i open a separate issue on HA? I believe you are the main driving force for mysensors platform so you are already aware of the issue,,,
Yes I'm aware and it's now on my todo. You can open an issue if you want. It doesn't hurt.
