I’m trying to sense if my gas heater is in an error state by sensing temperature change in the house. I get many false positives because the trend sensor samples in time intervals that are not aligned with the thermostat turning the heater on, thus the automation that sends me a notification thinks it’s broken.
It takes about 30min from when the thermostat turns on to when there is a measurable increase in temperature. I changed sampling intervals on the trend sensor and trigger intervals on the automation but it’s not reliable.
Is there a way to get a trend sensor to start sampling the temperature change only when the thermostat turns on?
