After adding a new sensor, the Sensor graph shows the history prior to the addition, but moving the cursor over to the prior history does not display the actual value in the little pop-up window that follows the cursor…
Obviously, this problem will disappear once I have seven days with the new sensor.
I just bought two sensors, & one is still in the box. I suspect when I add that, this problem will reappear for a week.
Edit #1: I decided I did not want to face this problem when I activated the 2nd sensor later, so I activated it six hours after activating the 1st one. I did not experience a new problem with beestat’s Sensor graph upon doing so. The only part of the graph where this continues to be a problem, is prior to the activation of the 1st sensor.
Edit #2: OK, the problem came back when I renamed the 2nd sensor !!! The problem occurs if there is any sensor that does not have data, & the name of the sensor sorts alphabetically before the name of the thermostat.
Putting "A "or "An " in front of the thermostat name (assuming there are no sensors that begin with “A”) “fixes” (works around) the problem !!! A leading space does not work, because ecobee strips it from the name.
Leading numerals also work, & have the advantage that you can (sort of) control which sensor gets which color.
