Best way to update LCD with NodeMCU?

[Bill Brower]

I just got the ESP hardware running with the LCD.
Right now from a script I update the device string associated with the LCD line, then I tell it to send the screen with that device in the event.

Is there a direct way from a script to send a string to a particular LCD line I am not seeing?

Thank you all.

Bill,

Try setting the device value to 100 as this should send the text set in the string to the device. I have not checked the cod but I think this is what I did.

Thank you so much. I'll give it a shot tonight.

Just did a quick test and you will need to use CAPI and "Send" is the command you need.

I would add this function to your script:

Function CallCAPI(ByVal intDevRef As Integer, ByVal strDevCmd As String) As CAPIControlResponse
    CallCAPI = CAPIControlResponse.Indeterminate
    For Each objCAPIControl As CAPIControl In hs.CAPIGetControl(intDevRef)
        If LCase(objCAPIControl.Label) = LCase(strDevCmd) Then
            CallCAPI = hs.CAPIControlHandler(objCAPIControl)
            Exit For
        End If
    Next
End Function

Then all you need to do is call the function with the required info like this:

CallCAPI(1275,"Send")

I hope this helps you.
