My sense went offline last night between 10:05 and 10:13 EST.
This morning my sense is reporting firmware
1.2.1463-2292892-master
where as yesterday it was reporting
1.1.1411-64be945-master.
I’ll also note that an updated Sense App (v1.8) for iPhone/iPad was released today.
See Ben’s post about that here which does also mention a firmware 1.2 requirement.
