Am90`

[steveb85]

Has anyone tried this with a Winix am90?

[steveb85]

I"ve been working on this. My AM90 seemed to use different servers, but then i am running into authentication issues. still plugging away at it.

[banzalik]

HI, do you still have some issues now?

[banzalik]

No activity

[steveb85]

I got a certain amount through, past the authentication, and i can get server responses, and i manually figured out what they meant, but haven’t been able to figure out how to code that into the plugin, it’s a bit different from the c545, i can control the unit via terminal, and read it, but that’s where i got to, and have to pick it back up again soon.

[banzalik]

I can add support Am90, it is not a big deal.

But if you ready to testing, and i need additional information from you.

If you alredy can contrlo by terminal, can you provide for me example of request (with fake devise ID)?

I need to make sure is url is correct.

[steveb85]

That's amazing, sorry it took me a day, had to get it together. So I'll share what i've got.

Here is how the control side works (at least for me)

axios({
method:'post',
url: 'https://smart.us.gw.winixcorp.com:9903/homedevice/control’,
data:
{
“body”: {
“controlData”: “17”,
“flag”: “N”,
“hDId”: “ZEROS20180424000184:72:07:23:3A:0E” // i don't know if this is unique to me, but without it it doesn't work
},
“header”: {
“deviceId" : "DCB12345-A1B1-1AB1-1A12-123A1234A1D1", //insert your device id here, this is a fake
"langCode": "EN", //again i tried taking various parts of this out, and it didn't work for me, so i just kept it as i found it via mitmproxy
"modelName": "iPhone11,8",
"networkKind": "WIFI",
"osKind": "IOS",
"osVer": "14.0.1",
"reqTime": "20201012124531228",
"resolution": "320*568",
'serverUId': "UID0100022637”}
}
})

Control data is as follows.

Power on 1
power off 2
Plasmawave off 18
Plasmawave on 17

Manual - 19

sleep 8
low 4
med 5
high 6
turbo 7
auto 3

As for status, here is how that works.

axios({
method:'post',
url: 'https://smart.us.gw.winixcorp.com:9903/homedevice/status',
data:{ body: {
"hDId": "ZEROS20180424000184:72:07:23:3A:0E" //not sure if this is device specific
},
header:{"deviceId" : "DCB12345-A1B1-1AB1-1A12-123A1234A1D1", //insert your device id here, this is a fake
"langCode": "EN",
"modelName": "iPhone11,8",
"networkKind": "WIFI",
"osKind": "IOS",
"osVer": "14.0.1",
"reqTime": "20201012124531228",
"resolution": "320*568",
'serverUId': "UID0100022637"}}, //crucial to have all these fields in the post header

},)

The return looks something like this

4QBPAAAAcAAAqAWoBQAxODA0MjRWMDAxAQ==

and here is how it's decoded.

Y = OFF (FIRST LETTER)
4 = AUTO (FIRST LETTER)

o = MANUAL LOW
k = manual Medium
i = manual high
h = manual turbo
g= manual sleep

3RD LETTER IS PLASMA = A= off B = on
seemingly randomly, manual sleep also has 8th letter is B not A

as you can see, i got a fair bit done, but then i hit a hard wall, not knowing how to put this into anything other than just using CLI to control it. anything you can do would be awesome.

[steveb85]

@banzalik is this helpful? Anything else I can do or try?

[steveb85]

just wanted to check in on this.

[shomegit]

I am interested in having control over the AM90 as well. I don't know if this helps but I can use a terminal window and this python program https://pypi.org/project/winix/ to control it.

[ecoolman]

Just a quick note, I installed this plugin last night with my am90, and it worked as is, only needed to input my device id which I grabbed using charles proxy for iOS.

Seems everything is working - in the Home app, I see current AQ, can control speed, toggle on/off, toggle plasma on/off, etc. Great work!

[steveb85]

@ecoolman thanks for that, I’m going to try again this week! I had a lot of trouble when i first tried it, but glad it worked for you!

[loudestnoise]

I was able to get my AM90 added by getting the Device ID using the instructions with mitmproxy, but it doesn't seem like I can get the purifier to switch to turbo mode. It does seem to give me the option of Manual v Auto, but when I change it to Manual I don't think it's actually doing it, and it never goes to Turbo. I mostly use my purifier as a white noise maker while I sleep, so Turbo is my optimal speed 😂😂😂

[fhughes90]

I just installed this plugin and used the instructions to retrieve the device_id from the mitmproxy. I can confirm this works for the AM90 model and I seem to have all functionality - turn plasma on/off, fan speed, status of air quality, and power on/off the device.

Only gotcha is I noticed the first time I saved the device_id and rebooted Homebridge, the controls were not working. I went to the AM90 device and noticed some lights were flashing. I cycled through on/off manually on the device and that seemed to fix everything.

[banzalik]

@fhughes90 Great! Thanks for your feedback.
