Easy question about variables

[Pauls]

Hi guys,

I have an easy question for the novice user, but i spend a week to get this working so please help me....
The simple thing is that i want to set a variable in the first LUA script to a certain number, lets say 1, then want to read it in the second script and set this variable to another number 2.
It sounds easy but i strangle with the correct notation.
below are parts of the scripts to get an idea:

first script:
if (devicechanged['Status alarm panel'] == 'On' and uservariable['alarm_status'] ~= '2') then
commandArray['Variable:alarm_status'] = tostring(2)
end

second script:
if (devicechanged['test'] == 'On' and uservariables['alarm_status'] == '2') then
commandArray['Variable:alarm_status']= tostring(5)
end

I have made an user variable "alarm_status" as an integer but get error messages like "attempt to index global 'uservariable' (a nil value)"
i have tried things like uservariable == alarm_status or alarm_variable ==2 or uservariable['alarm_variable'] == 2 but nothing works.

It will be much apriciated if someone could setup the basis code.
Thanks in advance

Greetz, Paul

Hi,

Can you start by changing "uservariable" to "uservariables" in the if-statement of your first script and then try again?

You are sending a string, but the variable is an integer...
Try commandArray['Variable:alarm_status'] = tonumber(2)

@mrf68: was a typo but thanks.
@BartdaMan, i have changed the script to:
event 1:

Code: Select all

if (devicechanged['Status alarm panel'] == 'On') then
    commandArray['Variable:alarm_status'] = tostring(2)

and
event 2:

Code: Select all

if (devicechanged['Voordeur sensor'] == "Open" and uservariables['alarm_status'] == 2) then
    commandArray['Variable:alarm_status'] = tostring (5)

this will do the trick, but to be honest i find it all quite devious.
It is of no influence if a change the uservariable to "string" or "integer" in setup/more options.

is there somewhere a complete overview of all domoticz LUA commands and their syntax?

Thanks both for your help.

Paul,

This is a start:

Not complete, but these examples will give you some ideas:
