Tell us about yourself!
Check out adafruit io. You can easily build a browser based UI, and its compatible with IFTTT. They have great tutorials at adafruit so stitching the projects together should not be a problem. Ill probably take the screen part of this project and add it to my almost finnished weatherstation.
Forgot to mention, I used the ATWINC1500 to get my station connected to the internet, and a NTP clock in favour of a RTC. Adafruit has good libraries for theor products that come with a bunch of example scetches.
