I love the ability to update linked hubs all at the same time. That said, I would really like to see the ability to control the default behavior. In other words, I would like to have the option to update linked hubs by default rather than having to click the checkbox each time.
A possible option for firmware updates: [RELEASE]Hub Updater v2 - Update multiple hubs with a button push
I think that is a great tool but I am more interested in having an default state for the upgrade mesh hubs that is built into the system update function in settings.
