1. The OS - Jessie
2. The class/size SD card? class 10 / 32GB
3. The Model Pi? - Pi2
4. The bug / issue:
I have relays connected to a MCP23008 which were working great since the last major update, but now they are both showing on the dashboard as “Unreachable”.
On the Extensions page I can see they are configured as outputs but when I try to toggle them, the button just changes to a spinning square.
I’ve just deleted and re-added them, and they are working again, but I’ve not seen any similar reports so I thought I’d let you know.
