Hi,
Just for people searching if the update gave problems (which I did ).
The experimental update from the latest firmware (1.5.13-rc.13 i think) to 1.5.13-rc.14 made the homey show a red ring and it was unreachable.
Fortunately, a PTP reboot fixed it. Unfortunately, I did the update remote so nothing worked until I came home.
Have a nice evening.
Nick
