Econo Cool #83

Closed kramttocs closed 2 years ago

kramttocs commented 2 years ago

Is it possible to add Econo Cool as a mode?

dlarrick commented 2 years ago

If it's possible to set it from the KumoCloud app, the answer is "probably." However, someone with a unit that can do that mode is going to have to do the reverse-engineering for how to set it.

Look at the Interactive use section of the pykumo readme. If it were me I'd look at what changes in the status dict for the indoor unit when in vs. not in that mode. If you're lucky it's another operation mode like "Cool", "Dry", etc. -- then need to figure out how to tell if a unit supports that mode. For example, for dry mode (available on some units) there's a hasModeDry flag in the profile retrieved from the unit.

Thanks for the quick reply. Just got my units setup yesterday so still learning but it doesn't look like it can be set in the app. Odd. Appreciate this integration and if I can figure anything out regarding this mode, I'll report back.

You got me curious. A quick Google search turns up: http://airconditioningwiki.com.au/mitsubishi-ac-econo-cool-mode/ So it looks like setting swing mode to "Swing" and the setpoint 2 degress higher will accomplish the same thing.

Thanks @dlarrick . Right now both units are in Econo Cool and they show in HA as:

Operation = Cool Fan mode = Auto Swing mode = auto (it is lowercase)

I get what you are saying but I wonder why the Swing Mode wouldn't be reflecting as 'Swing'?

dlarrick commented 2 years ago

Are the vanes oscillating back and forth? Or no? Swing mode "auto" lets the unit choose vane direction; it will choose different directions based on the distance from the setpoint. Swing mode "swing" moves the vanes pretty much constantly. At least that's my understanding.

kramttocs commented 2 years ago

Looks like your understanding is correct. The vanes move every now and then but not constantly.

So based on what we know now, Econo Cool could be accomplished by setting it to:

Cool, Auto, Auto, Desired Temp + 2 degrees

As that solves the concern, I'll go ahead and close this out. Thanks a lot!
