Quick Question regarding Magic Mirror cache

E3V3A

This is a very interesting question!

I have been thinking about all those calls to the font-awesome site that is (probably?) being continually generated every time a module refreshes. Just to re-fetch the same few icons… Seem crazy to me.

@chef The POST request isn’t sending it an image, it’s sending the URL to the image (e.g. http://192.168.2.18:9920/security/values/2). The problem is, it already has a cached copy of that image. I suggest you append a timestamp to trick electron into re-fetching the same image/resource.

You want to pass it a URL-encoded value, so use %3F as ? and just append your timestamp, like so:

http://192.168.2.48:8080/api/v1/modules/alert/show_ALERT?timer=10500&imageUrl=http://192.168.2.18:9920/security/values/2%3F
{INSERT TIMESTAMP HERE}&imageHeight=220px

Thaaaaank you sir! absolutely spot on! Now Alexa will describe the person in the security image (using M$ cognitive sense API), and the mirror in the kitchen flashes the security image as an alert.

Pretty bad@$$ actually!

@e3v3a so it would seem that the cache is in place to keep those images from a constant request situation.

However, now that you mention using FA icons on the alerts; I wasn’t able to successfully request FA images in my alerts.

Do you have an example of how you are doing it I could see?

@chef
You project sound awesome! IS it private, or will you share it with us?

chef

@e3v3a Sure I can share it!

There is a bit of a setup to get things rolling, but in the end, the security camera/alexa/Cognitive neural network is quite on point.

The best part is that if the neural network does get confused, the image is sent to the magic mirror anyway. So, Alexa will apologize for not being able to gather image information but will remind you to look at the magic mirror alert.

However, in both instances, the security camera image is posted on the mirror.
