I'm not sure if I'm doing something wrong, but changing the mode from the Dashboard doesn't trigger actions with this plugin for me.
It works if I click a new mode on the plugin device itself (and this change is also reflected on the Dashboard), but not the other way around.
My polling rate is set to 15. I'm not sure if there are any other settings that matter.
When I look at the House Modes Plugin device, none of the buttons are selected (Home, Away, Night, Vacation), unless I recently pushed one of them. I would expect the current mode to be green or something.
