Using Channel-IDs (that's not UUID)

SELECT
  timestamp/1000 as time_sec, 
  data.value as value, 
  properties.value as metric
FROM data
  LEFT JOIN properties ON (properties.entity_id = data.channel_id)
  LEFT JOIN entities ON (entities.id = data.channel_id)
You can’t perform that action at this time.
