You appear still to be missing the vital parentheses.

Hi AK,

when I put in the ()s, the code fails to run. Without them, it at least attempts to run.  That is the reason.


Thanks
Tony

I don't see a definition of the isBST function in your latest version.

That being the case, then

Code: [Select]
bst=isBST

if bst==0 then ...

will result in bst being nil and the if statement test being false.

Or
Code: [Select]
bst=isBST ()

results in an error, because you are trying to call a nil function.


When testing code, simplify, simplify, simplify.  There's just too many, rather baroque, constructs in there at the moment to see the wood for the trees.

Hi,

unfortunately the code is as simple as it can possibly be!

I have  function written in an i_...xml file, uploaded.

I have a script which calls the function, and then tests 2 commands which we can see work fine.

I've even tried adjusting the function, to actually return 0 only, and its still showing as true. I've also tried using the commands you provided where the return returns the .isdst variable directly, and still the same.

I don't think what I'm asking is too much, but maybe, something this simple, is just too simple for a home automation system?

Thanks
Tony

   function isBST()
   
      local v_time = os.date ("*t", os.time {year=2018, month=3, day=10})
        local v_dst = (v_time.isdst)

      if v_dst then
         return 1
      else
         return 0
      end
   end
