for Lua (and therewith for dzVents) time is a table.

Have been struggling with the same aspect, but not yet found a simple answer.

This should do it

Code: Select all

return {
    on      =   {      timer = {" every minute"}},

    data    =   {  testValue = { history = true, maxItems = 1 }},  -- Only one record in history
 
    execute = function(dz)
       -- initialize persistent historical data (only needed once)
        if dz.data.testValue.getLatest() == nil then
            dz.data.testValue.add( "initialized")  
        end
        
        if dz.data.testValue.get(1).time.daysAgo > 0 then
            dz.data.testValue.add("refreshed at " .. dz.time.rawDate .. ", " .. dz.time.rawTime)  
        end
    end
}
