I did the 1.7.919 Upgrade on my Vera 3. Had the not enough memory message so I did a network and full backup. Then restored to factory defaults. Did the upgrade, then did the restore (also checking the restore network box). looked like it went OK, but ended up with none of the switches coming back. each devise has this error message "Fail to load implementation file D_BinaryLight1.xml"
I looked in the luup files and sure enough there is no D_BinaryLight1.xml file. the .json file is there.
How do I restore that file?
