Let's Control It

I installed espeasy mega 20104 on a d1 mini. It works fine but I see e limited number of devices in the pull down menu (15).
I want to use the DHT11 but it is not on the list. How do I add it to the device list. The Wiki is not clear for me.
Sorry should be posted in the espeasy branch.

There are several builds called "normal", "test" and "dev".
Their differences are in the number of included plugins.
