[1] How to filter out spikes in graphs [2] Some data off by a factror 10

Grafana InfluxDB
1

I am logging my temperatures (air and floor) and humidity in every room in my house. For some of the rooms, the humidity temperature is off by a factor of 10 even if the data is correct in smartthing.

  1. How can I fix/debug this?
  2. Is there a way to filter out the spikes in the data?
