Thanks for the info about your Wizard, I have been able to duplicate this problem. It has to do with the Gateway and I’m fixing the bug in the firmware. In the meanwhile you can get it working by modifying your condition to read:
When Fan is Off, Anytime, everyday
Then Turn on Fan
When Fan is On, Anytime, every day
Then Turn off Fan
I’ll let you know when the new firmware is available for upgrade. Thanks.
