note update in my second post…
Hey Brian,
I am looking for something like this to monitor 2 different temp sensors and trigger a fan to vent out hot air from my garage (to save money on AC/electricity bill; same basic idea as a whole-house fan, but in garage; will eventually be doing something similar for the attic as well, but starting here first).
Is there any chance you would be willing to create a modified version (or show me how; or point me in the direction for where to go to learn how) of this SmartApp that doesn’t require the house thermostat (I had it all set up and just about to work, but then it wouldn’t work, because I don’t have a smart thermostat, and don’t need it in this particular project anyway)?
In my case, since this will be in my garage, the house thermostat won’t be involved. So, I just want the other parts. i.e…
- Monitor two temp sensors (one will be inside, at the hottest part of the garage, and the other outside; possibly just using the SmartWeather Station Tile which is already configured and ready for use in my ST system)
- If outside temp is lower than inside temp, turn switch on.
I already have all of the smart and dumb equipment that I need for the project (including a dumb fan, smart temp sensors, and a smart power switch). All have been connected to and are functioning properly with my version 1 SmartThings Hub.
Also, I already have a thread for my project (Dual Temp Monitoring Garage Cooling Fan System). So, I am already in the process of refining what’s all going to be involved. Now I just need to get the SmartApp part figured out, and your app looks like the closest thing to what I need among apps that are already out there, ready to go.
If I can get some help with this SmartApp aspect, I could begin saving a little money (less heat in the garage means less heat in the bedrooms above it and the rest of the house it is connected to, which means less electricity needed for AC to keep the house cool) in the very near future.
