I saw the Wemos D1 Mini yesterday for the first time. Since that time, they added 2 new shields to the page.
There are now 4 user designed shields (awaiting testing/certification) as well as a blank Prototyper shield so you can build your own.
It would be nice were there a similar board (w/shields) using the HC-05 Bluetooth module which appears to have more analog and digital pins than the WiFi module.
