all of them are 0.9.0. When you try to add them with the app, it updates to 0.9.0 before you can begin at least iOS, cant speak for android. I am trying to add another XENON to a mesh that has 2 XENONs and 1 BORON. I get to the second to the last step and it stalls. The last one I added made it to the final step, dropped the bluetooth "unexpectedly" yet it was connected. Even showed up in my dashboard as "no name" .
