iZone integration - Fails with 4-speed fan

[SgtBatten]

The problem

I am unable to discover my iZone controller. After an integration attempt the UI reports

"Aborted No devices found on the network"

The log return is shown below with an error coming from a FAN MODES related portion of the discovery.py. Unfortunately i am yet to figure out how to ssh into the container and view the file myself yet sorry.

I have also installed the integration using the configuration.yaml but it also fails to find any devices.

What is version of Home Assistant Core has the issue?

core-2021.6.3

What was the last working version of Home Assistant Core?

No response

What type of installation are you running?

Home Assistant OS

Integration causing the issue

iZone

I was able to google the following command and i can see my AC unit is returning "unknown" for fan auto

curl http://192.168.1.90:/SystemSettings
{"AirStreamDeviceUId":"20000xxxx","DeviceType":"ASH","SysOn":"off","SysMode":"heat","SysFan":"auto","SleepTimer":0,"UnitType":"Mitsubishi Heavy Industries","Supply":"21.5","Setpoint":"22.0","Temp":"19.6","RAS":"zones","CtrlZone":0,"Tag1":"","Tag2":"","Warnings":"none","ACError":" OK","Id":0,"EcoLock":"false","EcoMax":"30.0","EcoMin":"15.0","NoOfConst":1,"NoOfZones":5,"SysType":"320","AirflowLock":"off","UnitLocked":"false","FreeAir":"disabled","FanAuto":"unknown","OemMake":1}

The only valid responses are as far as i can tell listed here in controller.py

 _VALID_FAN_MODES = { 
       'disabled': [Fan.LOW, Fan.MED, Fan.HIGH],
        '3-speed': [Fan.LOW, Fan.MED, Fan.HIGH, Fan.AUTO],
        '2-speed': [Fan.LOW, Fan.HIGH, Fan.AUTO],
        'var-speed': [Fan.LOW, Fan.MED, Fan.HIGH, Fan.AUTO],
        }  # type: Dict[str, List[Fan]]

My unit, i believe is a 4 speed unit with an extra "boost speed" The iZone interface does have a 4 speed setting in the auto fan config so i guess i would need something like. [Fan.LOW, Fan.MED, Fan.HIGH, Fan.BOOST, Fan.AUTO],

even if that is incorrect it is still reporting unknown so perhaps i will need to edit the code myself on my local system. After a full day of googling I still have not worked out how to view the files inside a container. I prefer winscp for actual file browsing over pure shell but if someone has some guidance i can copy to edit controller.py that would be swell.

I just had a fiddle with my unit. Yes if you set the fan speeds to 4 speed on the unit it does report as ```'unknown```` fan modes.

Might I suggest that you set the fan speed on the unit to 3-speed? Do you need the extra speed?

[SgtBatten]

Hmm, i tried setting it to 3 speed a couple of hours ago and it is still reporting unknown. I reinitialised the controller in between. Is that all you did?

I can certainly do that to gain the initial discovery if it will work. But to be honest yes we have been needing the boost a bit as we have high ceilings. I'll see how it goes.

[SgtBatten]

I reset the bridge this time and it worked right away. Do you think setting it back to 4 speed in the future will be problematic if i need to

[Swamp-Ig]

Are you going to just leave the fan mode on Auto? What does the SysFan report when it's on boost mode?

I can probably contact the iZone people and ask them if it's consistently "unknown" when in 4-speed mode, then the library can be changed so the mapping works out. Alternately you could hack the python source to make it work for your particular case.

[SgtBatten]

It reports "top" when in boost mode.

understood. Thanks. I'm just fiddling with how to actually control the system now.

[SgtBatten]

I rang air stream this morning and he asked me to send through an email which I have done. Also confirmed a second time with MHI that my unit is indeed a 4 speed.

[SgtBatten]

Penny, any chance you could give me a hint as to where the controller.py file is so i can edit it. Just thinking I can replace 'var-speed' with 'unknown' for now but i cannot for the life of my work out where these files are. If it matters I am running HA OS in a VM, on a windows server.

[SgtBatten]

Okay i have leaned a lot today.

I made custom components and have got my unit working while set to 4-speed.

I have changes to two core integrations and pizone to submit pull requests to.
