Hello. 

Please forgive me if this has been previously asked and answered. 

I have six Deco X55 nodes at home. 

The hardware version of each node per the APP and the console is 1.0.

Each node is currently up-to-date with their firmware (1.5.1 Build 20240417 Rel. 52783)

On the label on the bottom of each node, the hardware version appears to be US/1.6.  This text appears to the right of the S/N.

My questions are:

• Am I identifying the hardware versions correctly?
• If I am,
  • How should I go about changing to the 1.6 branch of firmware release? 
  • OR should I just leave it alone?

Thank you for the help!
