hope this fix your issue I would add an extra worksheet to your add in and use ExecuteExcel4Macro to check for version updates.
code :
Public Sub CheckForUpdates()
    Const MasterPath As String = "C:\stackoverflow"
    Const MasterFileName As String = "MasterFile.xlam"
    Const WorkSheetName As String = "Settings"

    Dim Msg As String, Version As String
    Dim ButtonNumber As Long

    Version = getVersion(MasterPath, MasterFileName, WorkSheetName, 2, 2)

    With ThisWorkbook.Worksheets("Settings").Range("B2")
        If .Value <> Version Then
            Msg = getVersion(MasterPath, MasterFileName, WorkSheetName, 4, 2)
            ButtonNumber = IIf(getVersion(MasterPath, MasterFileName, WorkSheetName, 3, 2), vbCritical, vbInformation)
            MsgBox Msg, ButtonNumber, "Update Available"
        Else
            Application.OnTime Now + 4 / 24, "CheckForUpdates"
        End If

    End With

End Sub

Function getVersion(MasterPath As String, MasterFileName As String, WorkSheetName As String, RowNumber As Long, ColumnNumber As Long)
    If Right(MasterPath, 1) <> "\" Then MasterPath = MasterPath & "\"
    getVersion = ExecuteExcel4Macro("'" & MasterPath & "[" & MasterFileName & "]" & _
                                    WorkSheetName & "'!R" & RowNumber & "C" & ColumnNumber)
End Function

around this issue I don't have time to mock this up, so I don't know if it'll work, but try calling your table '##mytemptable' instead of '#mytemptable'
I'm guessing your issue is that your table isn't in scope anymore after you exec() the sql string. Temp tables preceded with two pound symbols are globally accessible.

Hope that helps I ended up not using any of these methods. I am on Heroku, and the amount of images/files I need to serve isn't large enough to warrant cloud storage.
What I did was create a file in tmp using one method and linking to it with link_to_remote to generate the file. Another link was made to an action which uses send_file with the path of the file I created in temp.

With these it helps To rename a file, you need 2 File objects. Create one using the original path and the second using the new name. Then call original.renameTo(newFile).
Deleting a file is even easier. Android contexts have a method called deleteFile(name). Call it to delete a file. Keep in mind that that method deletes a file from the local storage folders only and doesn't accept path separators. If you want to delete a file from a different location, there is a file.delete() method you could use too.

Does that help This will do the trick. You can assign it to a button or shortcut - it will refresh data from file in reverse upon each invocation.
code :
Sub reverseFile()

    ' put the file into the same dir as spreasheet
    Const FILE_NAME = "sensorData.txt"

    Dim fileNum As Integer
    Dim line As String
    Dim c As New Collection
    Dim a() As String
    Dim i As Long

    ' read file line-by-line
    fileNum = FreeFile()
    Open ThisWorkbook.Path & Application.PathSeparator _
            & FILE_NAME For Input As #fileNum

    While Not EOF(fileNum)
        Line Input #fileNum, line
        c.Add line
    Wend

    Close #fileNum

    ' reverse the input lines into array
    ReDim a(1 To c.Count)
    For i = LBound(a) To UBound(a): a(i) = c(c.Count - i + 1): Next i

    ' display results in the spreadsheet
    With Worksheets("Sheet1").[a1]
        .CurrentRegion.Clear
        .Resize(UBound(a), 1) = Application.Transpose(a)
    End With

End Sub
