Temperature Monitor

Temperature: what the probe in that room reads right now, not the temperature of the sensor board itself.
RH: relative humidity, how much moisture is in the air. Under 30% is dry, over 60% feels muggy.
Colors: blue is below 50°F, green is 50-75°F, amber is 75-85°F, red is above 85°F.
Time Range: how far back the charts look. The longer ranges are averaged into buckets, so brief spikes get smoothed out.
A gap in a line: that sensor stopped reporting for a while. The line picks back up when it returns.
Every 5 minutes: how often the sensors report, so a reading a few minutes old is normal and healthy.
Green dot / Online: the monitor itself is healthy; "updated Xs ago" is the age of the newest reading.
