how to tell a script to run once? like setup() in most mcu's

[abdolhamednik]

hello everyone

how can i write a script in order to run once only? like setup() in most mcu's

[jvdz]

I am a bit puzzled about the requirement for a scheduled script which needs to run only one time ?
Can you define the condition/occasion/circumstances this script would need to run?

Jos

exactly like mcu's where there is a setup() which runs to do some settings only once

[jvdz]

I had seen that bit, but that doesn't explain the purpose in domoticz yet for me.
So you want to run a script at the start of the domoticz service and run it one time?

yeah

yeah

You might want to look at dzVents system event Start

[jvdz]

The easiest way I would do it is to shell a script from the domoticz.sh script started by the service to do the required tasks. probably add a sleep in there for a couple of seconds to give Domoticz time to startup and then perform the tasks required.
Still not sure what it is you need to do a startup so am just thinking out loud here.

maybe it is required to shut a window at first to let the system know what the window state is

Not sure how your reply is an answer to my post.
It shouldn't be that hard to define what it is you want to accomplish at startup of Domoticz.

[abdolhamednik]

I would be thankful to know how "to shut a window whenever the system starts, i.e. a power loss and return"
you know, i don't have a sensor on the window to know its status. so i guess shutting first is the only way to make sure about it

[abdolhamednik]

thanks waaren. i'm reading that...

[abdolhamednik]

i followed it and wrote this short script, test, but it was not successful...

Code: Select all

return {
        on = {
          devices = {
             '<exact name of the switch>'
          }
        },
        execute = function(domoticz, switch)
          if (switch.state == 'On') then
             domoticz.log('Hey! I am on!')
          else
             domoticz.log('Hey! I am off!')
          end
        end
    }

of course i made these settings:
Using dzVents with Domoticz

In Domoticz go to Setup > Settings > Other and in the section EventSystem make sure the check-box ‘dzVents disabled’ is not checked. Also make sure that in the Security section in the settings (Setup > Settings > System > Local Networks (no username/password) you allow 127.0.0.1 (and / or ::1 when using IPv6 ) to not need a password. dzVents does use this port to get the location settings and to send certain commands to Domoticz. Finally make sure you have set your current location in Setup > Settings > System > Location, otherwise there is no way to determine nighttime/daytime state.

Can you define not successful.. ?

Did you replace <exact name of the switch > with the name of your switch ?
What did you expect and hat happened. What is in the log?

Yes, Of course. The switch is: R1(1.52)<8-3>[3]*

when i switched on and off that in the switches tab of domoticz, i hoped to see: "Hi! i am on or off" in the log. but saw only " ... admin switched on R1(1.52)<8-3>[3]* ... " or sth like that

When I use that name in the script and save it as dzVents, I see

Code: Select all

2020-10-22 08:34:38.683 Status: User: Admin initiated a switch command (672/R1(1.52)<8-3>[3]*/On)
2020-10-22 08:34:38.911 Status: dzVents: Info: Handling events for: "R1(1.52)<8-3>[3]*", value: "On"
2020-10-22 08:34:38.911 Status: dzVents: Info: ------ Start internal script: Script #6: Device: "R1(1.52)<8-3>[3]* (Virtual)", Index: 672
2020-10-22 08:34:38.913 Status: dzVents: Info: Hey! I am on!
2020-10-22 08:34:38.914 Status: dzVents: Info: ------ Finished Script #6

Can you have a look in [Setup][Settings] [Other] and check that both dzVents and EventSystem are set as enabled and loglevel to "Errors + minimal execution info" ?

[abdolhamednik]

you are right! i think there is a problem with my device which the manufacturer has installed domoticz on, he has renamed it as Avisa...
Here is what my log is:

2020-10-22 11:04:44.345 (hsb) Light/Switch (R1(1.52)<8-3>[3]*)
2020-10-22 11:04:44.304 Status: User: Admin initiated a switch command (3/R1(1.52)<8-3>[3]*/Off)

Did you set your location details in [Setup][Settings][Systems] ? If not domoticz / dzVents cannot determine the local time and everything derived from it.
Also kind of hard to help you if someone renamed system files in the dzVents runtime folder (and maybe on other places ?)
