Hi,
I am aware that there are multiple threads on troubleshooting the Google Assistant, but I did not find one on systematical troubleshooting. How do I test what is not working? Below please find my attempts, which may be a first start, but did not identify the root cause.
Now I am stuck with my MMM-AssistantMk2 and MMM-Hotword installation and configuration and look for step-by-step troubleshooting. When I started the Google Assistant installation, all installed MM modules are working fine, so I imaged the SD-card for an easy fallback.

My steps have been:

1. Installing MMM-AssistantMk2 + MMM-Hotword
2. Now I get a flashing bubble on the mirror and whenever I say the magic word: “smart-mirror” the string [“smart-mirror”] shows up next to the bubble on my Magic Mirror, but nothing seems to happen after (similar to the image on this page, just my hotword is not “Computer” but “smart mirror”: https://github.com/eouia/MMM-Hotword)

Maybe most of the things are successfully implemented but how do I get it to work?
I have no clue why or where it hangs, what are steps to identify where it stucks?

So far I have checked the following:

Note: fixing the [“Line 57 col 55 Missing semicolon.“]-issue does not make a difference, I copied-and-pasted this part from here: https://github.com/makepluscode/rpi-tutorial-advanced/tree/master/008-raspbian-magicmirror-google-assistant-latest
The audio/mic-settings in this sample seem to match my setup?

Does anybody have any idea what the next appropriate steps are to find where it hangs?
Any help is very much appreciated.

Hi all,
I feel quite happy with my Google Maps Traffic module but would like to increase the level of map details.
Some streets do not show, they are not displayed due to the zoom level.

Question:
Is there any (hidden?) trigger I can use to modify the level of details without changing the map-size or zoom-level?

@sdetweil
yes, that’s the case, the module is running fine until it turns the monitor black (after several hours).
There are more people in different threads having the same issue.
The module author does not seem to respond.
My workaround is a regular cron job restarting the MagicMirror.

I have the same issue. When I boot up the Magic Mirror in debug mode npm start dev & but the Chrome console tab tells me this nasty thing:

"You have included the Google Maps JavaScript API multiple times on this page." 
"This may cause unexpected errors."

However, everything looks perfectly nice on my MagicMirror.
All modules are successfully loaded, including “MMM-GoogleMapsTraffic”.

But on the next day, the latest my screen is entirely black.
It’s exactly the same thing as reported in this thread.

I am successfully running the MMM-ImageSlideshow module, but the images in my image directory are constantly changing. Looks like the images are all loaded from cached folder information.

How would I update the Dom to get my new images on the mirror?

Cheers

Is there any known solution for this?

Now I received feedback from Google, that confirms 28,000 MagicMirror map loads each month based on the $200 credit:

"Thank you for contacting Google Maps Platform Technical Support. My name is Xxx and I will gladly help you with your inquiry today.
Upon close inspection of your account, indeed, you have the Maps Javascript API correctly enabled.
Now, if you are using it to call Dynamic Maps, those 28,000 map loads are included within the $200 USD free monthly credit. Or, in other words, the $200 USD credit pays for the 28,000 map loads, ie, you get up to 28,000 map loads, for all intents and purposes, for free every month.

If you exceed the $200 threshold, then yes, your account will be charged according to the pricing sheet you will find at https://cloud.google.com/maps-platform/pricing/sheet/
That means that the monthly volume range above the 28,000 free map loads is 0.007 USD per each map load (or USD7 per 1000 map loads) up to 100,000 map loads.

If you want to make sure that you do not exceed the free monthly $200 threshold, you can cap your API usage [1] to a certain number of calls per day and/or set budget alerts [2].
We also provide an online calculator to estimate your usage at https://mapsplatformtransition.withgoogle.com/calculator.

I hope you find this information useful, and if you need further assistance or clarification on the documentation provided, please do not hesitate to let me know. I am happy to help!

Kind regards,
Xxx"

Hi,
I have installed and configured the Google MMM-GoogleMapsTraffic module, but feel lost in the Google pricing concept.

Question:
Will I ever be charged by Google using the MMM-GoogleMapsTraffic module with the standard values?
The module is just calling a simple map with traffic information but no routing

I checked the Google pricing web-page here:
https://cloud.google.com/maps-platform/pricing/sheet/?_ga=2.265062860.216645122.1555664995-842763991.1553803912

My best guess is that I am using the Maps JavaScript API to call Google Dynamic Maps and I get 28000 loads for free each month.
In addition I get $200 credit to purchase additional loads. Since 100000 loads cost $7 I get another 2800000 loads on top.
In total I get 28000 + 2800000 = 2828000 for free each month.

Is my understanding correct?, hence I do not have to pay since Google already provides sufficient usage?

@sdetweil
if you are the author of the RMV module its perfect, if you are not the author of this module it is perfect as well.
However, please accept that in my case the “MMM-RMV.js” requires auditing, otherwise it will not work.
I would be more than pleased if all editing can be done in the “config.js”, at least in my case it does not work.
The default values do not seem to be overriden.
Any idea why?

@sdetweil
I have not edited the code, I have created a pull-request.
All I can see it that it is working in my environment with my proposed change but not with the default values.
In case other users have a similar issue, I suggest to give it a try.
