My config.js

{
module: 'MMM-xiaomi',
position: 'bottom_left',
header: 'Temperature/Humidity', // This is optional
config: {
gatewayIP: '192.168.1.139',
gatewayToken: '369e4b19b7b01ae1227263bc952aaed5',
rooms: [
{
name: 'Salon',sortOrder: 10, devices: ['158d000117d108']
},
}

I hope you could help me.
Thank for your work.

Hi, sorry for the late reply. It seems that your gateway does not contain any devices, at least that is where the error comes from.
Your config is missing a closing ] for the rooms array - but I don't think this is the root cause. But maybe try that first...

Hi @mirko3000, I have the same error message:
TypeError: Cannot read property 'length' of undefined at Class.getDevices (/Users/sladak/MagicMirror/modules/MMM-xiaomi/node_helper.js:70:41) at /Users/sladak/MagicMirror/modules/MMM-xiaomi/node_helper.js:45:20

My module was working fine until my old gateway became defective. I bought a Xiaomi Mijia Gateway 3 and set it up. I readet out the Tokan of the new Gateway and also of all the sonsors. What I have seen, that the token has a longer string or different format then the old one, could this be the issue? than this is the only thing that I have changet in the config file. New Token of the gateway looks like this: 48473530637c7144596c703932666c37 I would be very grateful if you could help me. I love this module.

Hi @mirko3000
I think that the error occurs because of the old library. Would there be a way to include the new current library?
[(https://www.npmjs.com/package/node-mihome)]

Thanks a lot

Unfortunately not, I found an old used gateway and bought this one, now it works great again.
