Thanks for your useful tips.
Unfortunately, I loss the device few days ago. So, I can't recover a complete database. That why I was looking for a tool to recover a single device from an old backup file, without having to tinker the database, at the risk to crash my the current database.

I lost several temperature sensor that contained several years of history.

Is there a tool that allows you to easily recover a device that was deleted by mistake, or why not its data from the backup file, without going through a dB editor ?
