I am using the Discrete Panel Plugin (https://grafana.com/plugins/natel-discrete-panel) to map SmartThings sensor status, and at the beginning of each dataset is always ‘Null’. This does not seem to be tied to a certain time, as it is always at the beginning of the panel (far left in image).
Is there a way to filter the nulls, or have I configured the panel incorrectly? This is the query for the contact sensors:
SELECT last(“value”) FROM “contact” WHERE (“deviceName” = ‘Garage Position’) AND timeFilter GROUP BY time(__interval) fill(previous)
