But in the log I get this error:
Error: dzVents: ...userdata/scripts/dzVents/generated_scripts/SolarNoon.lua:14: attempt to call a nil value (field 'solarNoon')

What am I doing wrong here?

The goal is to update a text device with the solarnoon time, but that also fails with the nil value error....

domoticz.time.solarnoonInMinutes()

local hours = floor(minutes/60)
local minutes = floor(mod(minutes,60))

This user wants to use a standard dzvents function, gets an error and you tell him to do something complety different with the help of AI crap programming functions......

Better help him finding what is going wrong...

domoticz.time.solarnoonInMinutes()

return {
    on = {
        timer = { 'every 1 minutes' },  -- Voer het script elke minuut uit
    },
    logging = {
        level = domoticz.LOG_INFO,     -- Log niveau instellen op INFO
        marker = 'Solar Noon Logger'   -- Marker voor de log
    },
    execute = function(domoticz, triggeredItem)
        -- Bereken de solar noon in minuten sinds middernacht
        local solarNoonInMinutes = domoticz.time.solarnoonInMinutes

        -- Log de uitkomst
        domoticz.log('Solar Noon in minuten sinds middernacht: ' .. tostring(solarNoonInMinutes), domoticz.LOG_INFO)
    end
}

The `domoticz.utils` table in dzVents provides a collection of utility functions that can be helpful in your Domoticz scripting. Here's a list of commonly used functions:

* **`domoticz.utils.openURL(url)`**:
* Opens a URL. This can be used to send HTTP requests to external services.
* **`domoticz.utils.httpGET(url)`**:
* Performs an HTTP GET request and returns the response.
* **`domoticz.utils.httpPOST(url, data)`**:
* Performs an HTTP POST request with the provided data.
* **`domoticz.utils.toJSON(table)`**:
* Converts a Lua table to a JSON string.
* **`domoticz.utils.fromJSON(jsonString)`**:
* Parses a JSON string and returns a Lua table.
* **`domoticz.utils.base64Encode(string)`**:
* Encodes a string using Base64.
* **`domoticz.utils.base64Decode(string)`**:
* Decodes a Base64-encoded string.
* **`domoticz.utils.solarNoon(latitude, longitude)`**:
* Calculates the solar noon time (Unix timestamp) for the given latitude and longitude.
* **`domoticz.utils.sunrise(latitude, longitude, date)`**:
* Calculates the sunrise time (Unix timestamp) for the given latitude, longitude, and optional date. If date is omitted, it uses the current date.
* **`domoticz.utils.sunset(latitude, longitude, date)`**:
* Calculates the sunset time (Unix timestamp) for the given latitude, longitude, and optional date. If date is omitted, it uses the current date.
* **`domoticz.utils.daylength(latitude, longitude, date)`**:
* Calculates the day length (in seconds) for the given latitude, longitude, and optional date. If date is omitted, it uses the current date.
* **`domoticz.utils.moonPhase()`**:
* Returns the current moon phase.
* **`domoticz.utils.moonRise(latitude,longitude,date)`**:
* Returns the moon rise time.
* **`domoticz.utils.moonSet(latitude,longitude,date)`**:
* Returns the moon set time.

**Important Considerations:**

* The availability and behavior of these functions might vary slightly depending on your Domoticz version.
* When working with solar calculations, ensure that your Domoticz location settings (latitude and longitude) are accurate.
* When using http requests, be mindful of the security implications of sending and receiving data over the network.
* Always consult the Domoticz Wiki, and forums for the most up to date information.
