There must be something that I don't understand about Time variables and data. I had a script running properly for a long time, but not wokring anymore since I had to reinstall and upgrade to newer domtoicz/dzvents version. I was probably not coding properly and benefitting from some trick, but now, I can't understand why it doesn't work..
I'm now using Domoticz 2023.1, on Buster, with DZvents 3.1.8.
I can't succeed making work properly the getISO command. In below script (simplified version of my script to manage a small OPS for the raspberry), I want to keep memory of last "reset date/time" and display that date/time in clear text in the log as well as showing how many minutes since last reset.
But despite getISO works on another script I tested, using local variable, here it doesn't work.
Code: Select all
return
{
on =
{
timer =
{
'every 1 minutes', -- causes the script to be called every 3 minutes
},
},
data = {
lastReset = {initial= ''}
},
logging =
{
level = domoticz.LOG_DEBUG,
marker = getVoltage,
},
execute = function(dz)
local Time = require('Time')
if dz.data.lastReset == nil then
dz.log('testscript lastReset is NIL ', dz.LOG_INFO)
dz.data.lastReset=Time()
dz.log('testscript lastReset is now set at '..dz.data.lastReset.getISO(), dz.LOG_INFO)
end
if dz.data.lastReset == nil then
dz.log('testscript lastReset is still NIL !!', dz.LOG_INFO)
else
dz.log('testscript lastReset is not anymore NIL !! ', dz.LOG_INFO)
local temptime=dz.data.lastReset
if temptime == nil then
dz.log('testscript temptime is NIL ', dz.LOG_INFO)
else
dz.log('testscript valeur de temptime'..temptime.getISO(), dz.LOG_INFO)
end
end
if dz.data.lastReset ~= nil then
dz.log('testscript lastReset is not NIL and can be displayed !!'..dz.data.lastReset.getISO(), dz.LOG_INFO)
end
if (true ) then
dz.log('testscript critical warning domoticz UPS under too low voltage, starting reset', dz.LOG_INFO)
local now= Time()
dz.data.lastReset = now
end
dz.log('testscript last reset at time :'..dz.data.lastReset.getISO(), dz.LOG_INFO)
dz.log(' testscriptlast reset at '..dz.data.lastReset.getISO()..' which means in minutes :'..dz.data.lastReset.minutesAgo, dz.LOG_INFO)
end
}In fact, when the script reaches dz.log instructions with .getISO(), I receive error message like :
2023-04-17 13:53:00.476 Error: dzVents: Error: (3.1.8) An error occurred when calling event handler Test2 script
2023-04-17 13:53:00.476 Error: dzVents: Error: (3.1.8) ...oticz/scripts/dzVents/generated_scripts/Test2 script.lua:36: attempt to call a nil value (field 'getISO')
What I don't understand, is that in my test above, I test is the value of dz.data.lastReset is NIL and if yes, I initialize it at Time() and it seems working because next I see message :
2023-04-17 13:55:00.491 Status: dzVents: Info: ------ Start internal script: Test2 script:, trigger: "every 1 minutes"
2023-04-17 13:55:00.492 Status: dzVents: Info: testscript lastReset is not anymore NIL !!
2023-04-17 13:55:00.492 Status: dzVents: Info: ------ Finished Test2 script
but then I get the error message shown above. And with all the "IF" I put, I see that the value should not be NIL since scripts runs through the ELSE displaying "not anymore NIL"
I tried also to go through a local variable (cf code above with temptime), but it fails also.
If I do a script with simply
Code: Select all
local Time = require('Time')
local tonight = Time()
dz.log('test script tonight value:'..tonight.getISO(), dz.LOG_INFO)
dz.data.lastReset = tonightSo can you help me understanding what I do wrong ?
Also, maybe an extra question : to initialize the global variable lastReset upon first run, i use the " lastReset = {initial= ''} "statement. Is there a way to initialize it as a predefined date/time or even the current date/time ? When I try something like {initial=Time()} I have error message, bprobably because I don't have yet the "local Time=require ('Time') before the initialization.
Thanks a lot for your help !
