device variable watches

Plugins & Plugin Development Alternate UI

I want to use a device variable watch in a trigger. What exactly should I enter to test if a variable becomes “True”. Should I use the new and old variables in the test? Tried single, double quotes but the trigger is never active.

Thanks for your help

That depends a bit on the device and how it has chosen to represent true in its variable. Check the exact value in the device variable. Then the Lua expression should be something like :

new == "true"[/code] or [code]new == "1"

Thanks amg0

I have a scene to switch on and another one to switch off a device. What’s wrong with a trigger watching the variable “Status”. Why is always the same scene(9) triggered whatever the value of the status is. Scene 10 is always evaluated as second option

switch on

thx for the debug trace, very useful.
see the registeredWatch json object (attached ). the json data structure is a hash of hash of hash etc and is organized this way
devid, service, variable , “expressions container”, expression ( each and individual ) , index , scene to run and last evel

you seem to have expressions like this:

  • expression “True”, “1” or 1 will allways evaluate to true and therefore allways execute the scene
  • expression 0 will allways evaluate to false and therefore never execute the scene

Now the questions are:
a) what is the content of the VariableToSend and VariableToWatch ALTUI variable
b) what is ALTUI version
c) can you confirm in your scene screens what expressions you wanted ?

VariablesToWatch contains

;urn:upnp-org:serviceId:VContainer1#Variable2#7#4#‘True’#;urn:micasaverde-com:serviceId:SecuritySensor1#Tripped#10088#8#1#;urn:micasaverde-com:serviceId:SecuritySensor1#Tripped#10111#6#1#;urn:upnp-org:serviceId:SwitchPower1#Status#10130#9#1#;urn:upnp-org:serviceId:SwitchPower1#Status#10130#10#0#;urn:micasaverde-com:serviceId:SecuritySensor1#Tripped#10111#5#1#

VariablesToSend I do not see

Version is AltUI v0.85.787

Please find attached the trigger info

Your altUI version is too old, you should please upgrade.
Also your Lua expression is wrong. 1 meAns it will fire every time.
You want to have “new==1” or “new==0” depending on the case.

Thanks amg0

I upgraded to version 885

In the end it seems the correct expression for tripping a security sensor is new == “1” or new == “0”

Thanks for all your work
