I've not setup much in my WM100 (Willie)as yet (timer wise) here.
The one Willie per app limitation is a pain. I originally had this unit setup in my old phone but that meant I needed to take both phones up.
In the end I loaded my new phone to work with this Willie.
I have two IP cameras inside and two outside which allow me to see what if anything is on or off that shouldn't be.
These are all viewable from my phone so a quick switch to the wi-fi app allows me to change the state of anything that needs be.
The XPFM Inline Receiver Module I added to my outdoor wood furnace works like a charm.
As the days get warmer it doesn't make sense to have it heating to 150+ degrees. The ability to stop the damper from auto opening for long periods of time really does save on wood consumption.
I set up a scene to handle a period of no auto opening followed by a period of allowing auto opening.
I love the fact that a scene can be stopped and over ridden if needed it is perfect for this setup.
