I stored data into global variable (one for string, one for numbers).
Now I’d like to display that data from global variable to Habpanel.
I’ve created new items:
String BatteryStatus "Battery Bank Status" Number BatteryValue "Battery Bank Value"
In the rule, I tried to make these items to see the stored data:
BatteryStatus = status //status - is the global var BatteryValue = value //value - is the global var
2018-07-11 12:10:40.919 [ERROR] [ntime.internal.engine.RuleEngineImpl] - Rule 'battery bank status': An error occurred during the script execution: Cannot assign a value in null context.
Where I’m wrong, please?
