I would like to export the logs from devices - specifically the Home Energy Monitor.

I can view it in the application, but an 'export to excel' feature would be great!

Here is a powershell script that will dump the level data into a csv file. It requires the SQL Server Compact dll "System.Data.SqlServerCe.dll". For some reason I have been unable to get it to work by using the file that InControl comes with. Instead, first install the 64bit version of Microsoft SQL Server Compact 4.0 from https://www.microsoft.com/en-us/download/details.aspx?id=17876. Then, set the DB path and csv path at the top and run it.

I was using something similar to upload directly to GroveStreams which supports a step-style of charting that works well with this kind of ad hoc change-based data (instead of regular intervals), but the free amount of data they give you didn't last long.

If anyone knows a better way or can get the dll that comes with InControl to work so you don't have to install sql please let me know!

$command = New-Object "System.Data.SqlServerCe.SqlCeCommand"

$connection.Open()

$command.CommandText = "SELECT LevelLogs.LevelValue, levelLogs.logDate, ZWaveDevices.deviceName FROM ZWaveDevices INNER JOIN LevelLogs ON ZWaveDevices.deviceID=LevelLogs.deviceID;"
$sqlReader = $command.ExecuteReader()

$logs = while ($sqlReader.Read()) {
[pscustomobject] @{
"deviceName" = $sqlReader["deviceName"]
"logDate" = $sqlReader["logDate"]
"LevelValue" = $sqlReader["LevelValue"]
}
}

$logs | Export-Csv -NoTypeInformation $outputFilePath

$command.Dispose()

It's also worth noting that incontrol should be shutdown when accessing the DB in this way since it can lock the DB and prevent incontrol from accessing it.
