Hi everyone, I’m encountering an issue with the `Homey.logic.updateVariable` function in my Homey script. I’m trying to update a logic variable named `conteggio_eventi`. The variable is successfully retrieved with the following ID: `8bed27e2-2905-430b-91fe-36ca4d37d0a1`.

Here’s what I’ve done so far:

1. I successfully fetch logic variables using `Homey.logic.getVariables()`.
2. I confirm the variable’s ID and value.
3. I call `Homey.logic.updateVariable` using the following formats:

- `{ id: '8bed27e2-2905-430b-91fe-36ca4d37d0a1', value: 1 }`
- `{ variable: { id: '8bed27e2-2905-430b-91fe-36ca4d37d0a1', value: 1 } }`

In both cases, I get the error: **“Missing Parameter: variable”**.

Here’s the output from the logs:

Attempting to update the “conteggio\_eventi” variable  
Object passed to updateVariable: { variable: { id: ‘8bed27e2-2905-430b-91fe-36ca4d37d0a1’, value: 1 } }  
UpdateVariable: Error - Missing Parameter: variable

I’m unsure what parameter might be missing or if I’m using the wrong format. Has anyone had experience with this function and can help me resolve the issue?

Thank you in advance!  
Ciao, Andrea

You seem to use a different syntax:

`Homey.logic.updateVariable({id: TodaysDateId, variable: {'value' : dateNum}} )`

Here is my current script: let testDay = new Date(); let dateNum = testDay.getDate(); let monthTxtShort = testDay.toLocaleString('fefault', { month: 'short'}) let TodaysDate = Object.values(await Homey.logic.getVariables()).find(({name}) =\> name === "TodaysDate"); let TodaysDateId = TodaysDate.id let MonthTextShort = Object.values(await Homey.logic.getVariables()).find(({name}) =\> name === "MonthTextShort"); let MonthTextShortId = MonthTextShort.id Homey.logic…
