So odd thing happening at the moment.
Came home to find the green light of the front flashing and hashrate steadily decreasing.
SSh into it and its responding very slowly. A good minute to got the login screen, then another minute or so to get passed it.
I've restarted the hub and will see how it goes.
Post about it in the Gekko channel on Kano's discord site. Sidehack hangs out quite a bit there as does the guy Sidehack worked with for the Smarthub.
