This firmware has not been officially released yet, but it is available for test by choosing Advanced, Download from Vera’s setup site, and putting in the URL below. Note that Vera’s security layer has not yet been certified by Zensys, and Mi Casa Verde has not done any independent verification of the Z-Wave security protocol. So Mi Casa Verde makes no representations about the security and you should use this beta software for testing purposes only.
