Error: state is nil for item.level: nil

[HvdW]

Hi,
I am not able to find an example on Google to retrieve the cause of this error message.

Code: Select all

2024-11-20 18:35:00.651 Error: dzVents: Car charging on PV Power: Error: state is nil for item.level: nil

The script runs smooth but I want to get rid of this error message.
Checked and logged everything state and level, all OK

[waltervl]

I never have seen this error but it could be a misformed table of item.
Is item an domoticz object or a json from external?

[HvdW]

The only item word in the script is triggeredItem that's why I am wondering.
I have put a lot of debug statements inside, all flawless.
As mentioned, a Google search didn't give me a clue where to search either.

Beter post the complete script.

Guess it has to be this line?:

Code: Select all

local chargeLevelSet = domoticz.devices('XC40 battery charge set').level

Check the devicename and type whether it really has field level.
To make sure that is the one, you could change the line to:

Code: Select all

local chargeLevelSet = domoticz.devices('XC40 battery charge set').level or '??'

[HvdW]

Code: Select all

local chargeLevelSet = 82 

gives the same result
