Hello at all
i have a question to the influxDB Part of Chirpstack Integration.
as the documentation says, informations like SF are stored as DR in de device_uplink meassurement. i want to draw e graph in Grafana, which shows the history of SF/DR.
As the DR filed is a tag, i have problems with the influxDB querry - does anyone knows, how to do such a select? InfluxDB says, you can’t use selects on tags only - so you need a field (for example value).
So if anyone could tell me, how to do the influx querry, i would be very happy.
thanks in advance,
