MMM-Face-Reco-DNN , Blank Screen error

[sdetweil]

@oberk so, its sounds like you have a short time to logoff

and then you don’t have the classes: configured in config.js on the modules that match the person identifier

[oberk]

@sdetweil

You are right, thank you,
Sorted.

[N3UR0515]

@oberk Hey, hope you are well!

How did you get this to work correctly?
I have successfully installed everything and my face gets detected successfully. I get the notification pop up saying I’m detected but it doesn’t switch profiles. The modules all have classes assigned too.

Am I missing something?

Thanks,
Alfie

@N3UR0515 show a couple modules w classes defined

[N3UR0515]

@sdetweil Hey, thanks for the quick reply.

Here is my full config, it’s a fresh install with just the 2 modules installed.

/* Config Sample

@N3UR0515 and what is the user name detected

[N3UR0515]

@sdetweil The username detected is alfie.

Here is a log extract confirming it successfully detects me:

@N3UR0515 you cant have profile switcher AND facereco. they do the same thing

so, only newsfeed should show for alfie

[N3UR0515]

@sdetweil Thank you so much! Knew I’d done something wrong.

Not sure why I thought they had to be used together.

Thanks for the speedy responses👊

[sdetweil]

@N3UR0515 you would use profileswitcher if you had something else advising which profile to use and nothing else doing that function

facereco is doing it all
