The "Attempt to decode JSON" means that the hub has returned an HTML page rather than a JSON response. That usually means the hub is showing an error page.

What happens if you try to manually run a failing command?

> curl 'http://192.168.7.57/apps/api/7048/devices/260/off?access_token=28df4a30-39a2-4f3c-a44c-fe414ca4e2ee'

[jason0x43]

Is this still happening?
