Updating from Huddle Hub 1.x-2.x-3.x to Modena Hub 4.0

Logical scheme

• Units on 1.x need a manual update to version 2.0.2.55
  This is a necessary intermediate step before updating the unit to versions 3.x and 4.x
  Firmware 2.0.2.55 is available for download on this page
   
• Units on 2.x, and 3.x SRE (Single Room Edition) will automatically follow Modena Hub branch 4.0
   
• Only 3.x MRE (Multi Room Edition) units will remain by default on version branch 3.3
  This will preserve the availability of Smart Rooms with this version.
  However, 3.x MRE units can be easily updated to 4.x with a manual update

Technical scheme

From a technical perspective, all versions prior to 4.0 are temporarily updated to version 3.3.4.9, which will assign the correct update path depending on the firmware and SRE/MRE version. Modena Hub will be automatically rebooted twice to apply the new updates.

Compatibility with clients

Modena Hub firmware 4.0 requires all connecting clients (Windows, MacOS, Android, iOS) to be updated to the latest 4.0 releases.

Restore to factory

If a Huddle Hub with version 4.0 is restored to factory defaults the unit reverts to the firmware originally installed in the factory (typically 1.x, 2.0, 2.3, or 3.0) and then, if connected to the internet, automatically updates itself following the above path.

Maintenance of 3.3 version

No new feature will be implemented or released in version 3.3 branch. The download of the 3.3 version is still available for compatibility with older installations.

Downgrading from 4.0 to 3.3

If you accidentally updated from 3.3 MRE to 4.0 and would like to downgrade in order to regain the extra Smart Rooms, proceed as follows.

• Download the most recent 3.3 firmware from the 3.3 download page 
• Disconnect Modena from internet, by simply removing the Ethernet cable, and perform a factory restore.
• When the procedure is completed, reconnect the Ethernet cable without rebooting, and access the web admin configuration
• From the Update page, disable the automatic updates at reboot
• Navigate to Update -> Manually load the firmware, and select the <HHO_3.3.x.x.dat> file you just downloaded. The new firmware will be installed, and the unit rebooted
  (Please note that in case the unit reverted to version 1.x, the firmware should be first updated to version 2.0.2.55, as an intermediate step, and then to version 3.3.x.x)
