update device status with LUA

Hi,
I can't seem to update a device status with LUA script.
Situation
- I have a user variable 'var-security'
- A device named 'Alarm' setup as a 'selector' with two levels:
10: AAN
20: UIT
I try to run a LUA script to update the device status to AAN or UIT when the user variable 'var-security' is updated from 1 to 0 or the other way around.
Code: Select all
commandArray = {}
if ( uservariables['var-security'] == '1' ) then
commandArray ['Alarm'] = 'Set Level: 10'
elseif ( uservariables['var-security'] == '0' ) then
commandArray ['Alarm'] = 'Set Level: 20'
end
return commandArray
Unfortunately, the status does not change.
Using commandArray ['Alarm'] = 'AAN' or 'On' or '1' does not work either.
Any tips or solutions for this?
A completely new code is welcome too.
Thanks,
Roel

Is your script a file in the LUA scripts folder? In that case the name should be like script_variable_name.lua.
Or is your script in the local editor in Domoticz? In that case you should select UserVariable.

Think you need to set the value to 10 or 20 like:

I use the web editor. Do you mean to replace 'uservariables' with 'UserVariable'?
That seems wrong, but I tried it anyway. Does not work.
thanks

I mean the pulldown menu just Above the tick box Event active, that should be set to UserVariable for this script.
So no changes to the LUA code

What you want is -
commandArray ['Alarm'] = 'Set Level 20'
without the ':'

Hi Westcott,
No, that does not matter. This is however not as documented.
Documentation says that "Set Level xx" is for dimmers and for selectors, you should use "Set Level: xx"
It seems that both work fine.
The issue was that my variable is an integer, but I used '1' in my script. Once I removed the quotes, my script went into the functions.
And as you say, then without ':' it sets the level correctly.
Thank you all for thinking with me!
Cheers,
Roel

Final script that worked:
Code: Select all
commandArray = {}
-- print to log
print("script running: alarm");
if (uservariables['var-security'] == 1 ) then
-- set device level to 10
commandArray ['Alarm'] = 'Set Level: 10'
-- print to log
print ("Alarm Turned On");
elseif (uservariables['var-security'] == 0 ) then
-- set device level to 20
commandArray ['Alarm'] = 'Set Level: 20'
-- print to log
print("Alarm Turned Off");
end
return commandArray
