I live in Calgary, Alberta, Canada and have a mandevilla plant that was doing VERY well over the summer. I have brought it inside the house and it seems to be dying. The leaves are falling off and it seems to be getting worse. I am ensuring I am watering only when the soil is dry (I use a meter) and have it on an inside wall. Inside temperature is about 15-20 Celsius on a daily basis and gets indirect sun. Can you help me save this beautiful plant? Thank you!

Plant stress due to a change in location, temp., etc. can lead to yellow leaves and subsequent leaf loss. It should recover on its own, going dormant over winter. Once temps warm back up the plant will begin putting out new growth.
