Finally added the outside temp sensor. This is a project I did in Winter so I did not want to start punching holes through my house when it's 30 below and I doubt the caulk would cure properly. Finally added it today. Made a small hole, put in a piece of pex, passed the sensor through, and caulked the hell out of it at both ends, it's curing now. Hopefully it wont leak. D: Next storm I'll have to keep a close eye, but think I should be fine. I've installed a dryer vent before and it does not leak. :D Caulk and proper hole angle is key.
Now I get an actual reading on the last entry. Yet another way to check the weather without needing to go outside. Because who would want to do that. :P
Also another sign Winter is coming, it's 9pm and it's already dark out. I was pretty much racing against the clock finalizing the outside portion.
I may in the future add an outside intake with a damper that opens/closes based on the outside temp, and what it's set at. So when I get AC, say I set the temp to 20 but it's night time so it's 15 outside, then it wont run the compressor, it will just open the damper. Same idea with the furnace, if it happens to be a hot day then it wont run. For now it's nothing more than a convenience of getting a real time temp... and pretty graphs in Pandora. Yeah I know, I'm a geek. :D
