Room Temperature Log — Free Line Chart Template
This Room Temperature Log template plots indoor temperatures across the day on a clean line chart, so you can see exactly when and where your home heats up or cools down. The sample data tracks two rooms from 6am to 8pm, rising from a cool 18 degrees in the early morning to a midday peak of 24 around 12pm-4pm before easing back to 22 by evening. It is a ready-made starting point for spotting comfort swings, drafty rooms, or HVAC timing without building a chart from scratch.
