MMM-xiaomi - Temperature and Humidity from your smarthome

Albert2002 · Nov 4, 2017, 10:47 AM

I am a step ahead!

I followed the instructions to get the token “Getting the token when using the Mi Home app”
This was working. I could see all the connected devices to the Gateway.

pi@raspberrypi:~/MagicMirror/modules/MMM-xiaomi $ miio --discover --sync
 INFO  Discovering devices. Press Ctrl+C to stop.

Device ID: 52238776

Device ID: 158d00015736a8
Model info: lumi.sensor_ht (sensor)
Address: Owned by 52238776
Token: Automatic via parent device

At this point I had to switch over to the Pi with the installed MagicMirror:

pi@MagicMirror:~ $ miio --discover
 INFO  Discovering devices. Press Ctrl+C to stop.

Device ID: 52238776
Model info: Unknown 
Address: 192.168.2.107 
Token: ???
Support: Unknown

I’ve updated the Token as described:

pi@MagicMirror:~ $ miio --update 52238776 --token 6eea5ac1eb475bfedbfff98aab7c2bc7
 INFO  Attempting to update 52238776
 INFO  Device updated

I’ve searched for devices again. Now with success!


pi@MagicMirror:~ $ miio --discover

Device ID: 158d00015736a8
Model info: lumi.sensor_ht (sensor)
Address: Owned by 52238776

The problem so far is, that I still don’t get any informations visible in MM. I’ve tried ‘158d00015736a8’ and as well ‘52238776’ as id.
The second problem is, that I’ve lost the Gateway in my Mi Home app after updating the Token!

The question is, how to copy ( Store?) over the Token to a different Machine?

mm error:

Ok at least some progress. So first to enable your manual token just update the configuration:

config: {
	 interval: 30,
	 gatewayIP: '192.168.13.1',
	 gatewayToken: '6eea5ac1eb475bfedbfff98aab7c2bc7',
	 devices : [{
	     id: '158d00015736a8',
	     name: 'MyRoom1'
	 }]
}

You only need the IDs from your sensors, not the gateway.

About the Mi Home App and your lost token, I would try once this works to reconfigure your gateway with the Mi Home app, and then try to fetch the auto-token again (in your first sample it seems to provide auto-token).

Albert2002 · Nov 4, 2017, 11:50 AM

I did the steps again to get the (new) Token. Now, I have a new Token and the Gateway again in my Mi Home app. I didn’t updated the Token on the different machine this time.

I’ve tried out your new config. I still don’t see more than before on the MM, but I don’t have an error log as well, which make it a bit more harder.

I have checked the IP address of the Gateway, its still the same. Dev is still enabled.

My config with the new Token.

		{
		module: 'MMM-xiaomi',
		position: 'bottom_left',
		header: 'Temperatur / Feuchtigkeit',  // This is optional
		config: {
			interval: 30,
			gatewayIP: '192.168.2.107',
			gatewayToken: '050591e66a82f7adc92bfa6b03058cdb',
			devices: [{ id: '158d00015736a8', name: 'Wohnzimmer' }]
			// See 'Configuration options' for more information.
				}
		},

Edit:

I get a error when I try to discover with miio:

pi@MagicMirror:~/MagicMirror/modules/MMM-xiaomi/node_modules/miio $ miio --discover

Albert2002 · Nov 4, 2017, 11:55 AM

Where did miio stored the Token?
The Token Miio used “Token: 6eea5ac1eb475bfedbfff98aab7c2bc7 via stored token”
is the old one! the new one is 050591e66a82f7adc92bfa6b03058cdb

mirko3000 · Nov 4, 2017, 4:32 PM

Hmm not sure about miio details, I just know that you can sync the tokens via

miio --discover --sync

Else I would try manually setting to the correct (new) token.
For the MM: try to uncomment line 51 in node_helper.js, this logs all found devices. You could also add some more logs here to see where the program fails.

Albert2002 · Nov 5, 2017, 12:49 AM

Hi Mirko! Thanks for your reply!

Before and after I uncommented the line 51 and restartet MM.
Still with the old Token

pi@MagicMirror:~ $ miio --discover --sync
 INFO  Discovering devices. Press Ctrl+C to stop.

Device ID: 52238776
Model info: Unknown 
Address: 192.168.2.107

Support: Unknown

(node:25652) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Call to device timed out

But right now after uncommenting the line the error log is different. In the log i can already see the Temperature and humidity (_properties: { temperature: 19.51, humidity: 62.44 },)!! The next step!

One more. When I run the MM as standalone server (node serveronly) I get this in the Browser console:

Try the latest update (git pull), I just checked for null items - even i that should not happen.

I did so. Restarted MM.
No errors in the logs.

mm out:

Ok, now another try :) Forgot to add utility class which was already present from other modules on my instance. Please update from GIT.
