@sdetweil - the documentation indicates ‘It does not do recursive search of image folders’, which I would prefer. The author also indicates he cut out features from the module he forked, but didn’t specify what features. As I said, time will tell whether I stick with it, or give another a try.

I am trying MMM-SimpleBGSlideshow, but may try the one Sam is using. I do have this one up an running, but it appears to have limited functionality.

@ BKeyport - thanks. I’ve disabled that module and found one that works. I will work on the MMM-DynamicWeather, hopefully today. Thanks to you and Sam for the support!

@sdetweil - thanks. I may just disable the two offending modules for now, and then dig thru that post.

Sam - thanks. Do you happen to know whether this is also true for MMM-DynamicWeather?

New install, using Sam D’s install script on buster: It runs OK with default modules as well as MMM-Worldclock [the MM displays on the local monitor, as well as from another machine using the browser]. When I enable either MMM-BackgroundSlideshow or MMM-DynamicWeather I get both a black screen on the local display as well as the web server stops as evidenced by being unable to connect in a browser from another machine. The first thing that catches my eye in the logs is an error that the linux-armv7 binaries cannot be used on the linux-armdefault platform. I am running on a Raspberry Pi 4. Any ideas of what went wrong?

@sdetweil: THANKS, I knew it was something simple… I guess i read the instructions [“Go to Fitbit …”] and just went to Fitbit, using my usual approach of launching it via my password manager. When I instead went to the dev site, it was straightforward to create an app. Thanks again!

I would love to try this module, but at stuck at the starting block of creating an app on the Fitbit site… When I go to Settings -> Applications on the FitBit site there is a place where it would list the authorized applications, but does not allow creation of a new application. I tried in Firefox and Chrome, but get the same output. My web searching seems to indicate most of the results are adding an app to the actual FitBit wearable, not to the account. This is an older ‘Alta’ model, and it has no fancy bells and whistles - just basic tracking which DOES show up on the FitBit web site. I feel like I am missing something very basic, but am just not seeing it.

@bkeyport - Thanks! It works as you describe. I thought I had already tried removing that code to no avail, but obviously hadn’t. Thanks again!

Never mind… I think i have fixed it for now. I went into Google Calendar in the browser, searched for each event and deleted all recurrences. Within a couple of update cycles on the MagicMirror the events disappeared.
