Well not a mirror yet but my first build is coming along better than I thought it would. Still have some plans but the NHL and NFL modules seem to be my current sticking points.

Modules Used:
Default Weather
MMM-Roomba
MMM-Ring
MMM-CalendarExt (Played with Ext2 but seem to like Ext better so far)
Background image was added using custom CSS

Want to build a frame and probably put a mirror on the front. Other plans include wanting to add buttons for turning on the game scores in place of the weather. Add motion detection as well.

Just started understanding the modules and building a couple of modules that will show the status of our solar system. The system is by Tigo Energy and they have an API (cost $20.00 per year for access beyond their own interface. Seems to work but concerned about the reliability as it was down for 4 days. I have not spend much time on the actual display of data yet, just working through the API Calls. Now to start to formatting and cleaning it up. Been a fun exercise overall.
