MMM-xiaomi/node_helper.js error: 'length' of undefined

Hi guys,

I installed the module of MMM-xiaomi. I got the xiaomi gateway token via android emulator and https://miio.loli.ren. my config.js is as following:

        {
            module: 'MMM-xiaomi',
            position: 'top_right',
            header: 'Temperature / Humidity',
            config: {
                gatewayIP: '192.168.186.157',
                gatewayToken: 'xxxxxxxxxxd9e32a8373a409e651c333882',
                showWindow: true,
                showVentilation: true,
                showLights: false,
                audioNotifications: true,
                rooms: [
                    { name: 'Salon', sortOrder: 10, devices: ['158d0002422571', '158d00022aa866'] }
                ]
            }
        }

Then I run MagicMirror. The MMM-xiaomi module is stuck at "Connecting to Xiaomi gateway...", and the console output log is as following:

2019-03-03T21:23:45 <error> TypeError: Cannot read property 'length' of undefined
    at Class.getDevices (/home/pi/MagicMirror/modules/MMM-xiaomi/node_helper.js:70:41)
    at /home/pi/MagicMirror/modules/MMM-xiaomi/node_helper.js:45:20
    at <anonymous> (/: )

I'm sure the gateway token is correct. Could anyone give me some suggestions? Thanks in advance!

Hi, based on the log and the code where it seems to give you the error I would guess no device could be found. Did you try with the miio console tools to identify the connected devices?

Yes, I run the command "miio discover" and the gateway was not be found:

......
Device ID: 99235478
Model info: Unknown
Address: 192.168.186.166
Token: ???
Support: Unknown
......

I'm sure the above device is my gateway. I search xiaomi related documents from internet and I almost guess that Xiaomi Air Conditioner Companion (gateway) is not support by miio library.

Thanks for your suggestion.

Sorry, devices: '158d0002422571' is a switch, not a temperature/humidity sensor. Thanks!
