   history:
+  V1.2.1  31.03.19      small bug fixed 
+                        values in model database are rounded
+                        mDNS and OTA did not work in AP mode
   V1.2    23.02.19      Add OTA (over the air update)
                         mDNS default enabled
                         add percentlists for many battery types
