System Monitor version 0.4 and memory information

hello,

I have installed this System Monitor plugin in UI7 in order to follow the VeraLite ressources utilization
, specially about the memory usage.

The " Memory available" variable is only displayed in the device SysMon created and nothing about the others variables of the plugin like memoryfree , memoryTotal , memoryCatched , memoryUsed …

Is it related to UI7 or something else ?
