Hi ST Community – I’m a relatively new member, taking the HA plunge just a few weeks ago. I’ve learned a lot about wiring that I never knew before and gotten lots of great tips from reading through the threads here. My ST system is now up to over 100 physical and virtual devices and I’ve automated most of the major tasks and rooms in our home, but there’s one thing I haven’t been able to do yet. I’m hoping some folks here have some ideas.
Our garage gets quite hot during the North Carolina summers and traditionally I’ve had a box fan in the window that runs continuously 24 hours a day. Some days I have it positioned pointing outward and essentially use it as an exhaust fan, other days I point it inward to draw cooler air from the outside (such as in the evenings).
What I would like to do is setup a reversible box fan similar to this one I found on Amazon to be able to be controlled by SmartThings. I would then use the temperature sensors in the garage and the outside temperature to code the logic as to whether to run the fan in exhaust or draw mode, as well as shut it off when not needed.
I’m not aware of any commercial products that would meet my needs, so I realize this is probably going to involve some sort of hackery on my part. I’ve never done anything like that before so I’m hoping you guys have some similar experiences or projects that I can use as guides as I try to figure this one out.
Looking forward to your inputs.
