How to set timer to last day of the month

Hi all,
Thanks to the great help of this forum Inwas able to use dzvents for my energy meter. I have a script to copy the current week total to another device to store it as last week. A timer running each saturday at 23:55 does that job.
Now I want something similar for the month values. Like “rune every last day of the month at 23:55”. Should be possible but I am not able to figure that out.
Can’t be difficult, but I don’t see it...
Help appeciated. As always

Cron does the job.
Take a look
over here.
I'm testing this one:
If you're lucky to be using one of those implementations, it's as simple as:
55 23 L * * ?

This could do it
Code: Select all
return
{
on =
{
timer =
{
'at 23:55 on 28/2,29/2,30/*,31/*',
},
},
execute = function(dz, item)
if os.date("%d", os.time() + 24 * 3600 ) ~= '01' then
dz.log(item.trigger .. " ==>> today is not the last day of the month" , dz.LOG_FORCE)
return
else
dz.log(item.trigger .. " ==>> today is the last day of the month" , dz.LOG_FORCE)
end
dz.log('rest of the script below this line', dz.LOG_FORCE )
end
}

That's 7 times twice on 30th and 31th

True but in the execute part of the script there is an extra check that will stop the execution of the script if it is not the last day of the month, before the scripts real work starts.
Do you know a better way in pure dzVents ?

Correct @waaren
For simplicity you could trigger it every day as well, like:
Code: Select all
return
{
on =
{
timer =
{
'at 23:55',
},
},
execute = function(dz, item)
if os.date("%d", os.time() + 24 * 3600 ) ~= '01' then
dz.log(item.trigger .. " ==>> today is not the last day of the month" , dz.LOG_FORCE)
return
else
dz.log(item.trigger .. " ==>> today is the last day of the month" , dz.LOG_FORCE)
end
dz.log('rest of the script below this line', dz.LOG_FORCE )
end
}

The time rule looks indeed a bit intricate at first but that is only once and you save 365 - 19 = 346 unnecessary script triggers yearly by using it.
I can live with both approaches

Correct again @Waaren
I like script simplicity and computers don't care about repetition.
How many times a day is this script being run to check if it's 23:55?
