Hi guys, my first post here on Grafana forum
Started experimenting with node-red, influxdb, and grafana as a way of building a “beehive science station”.
Basically there is one sensor connected to a Raspberry pi3 GPOI4:
DHT22 with humidity% and temperature in C.
Also, connected with USB to Rpi I have a Sparkfun OpenScale board, that has these sensors reporting to Rpi through serial-usb:
Load cell, in Kg
DS18B20 external temperature sensor in C.
OpenScale onboard temperature sensor in C.
My problem is with the hover tooltip not showing the numbers for the DHT22 measurements. See screenshot
I made a panel with all my measurements on, just for illustration.
This screenshot shows how I set up the querries(suspect this is where I am in error):
The strange thing is though that the panel shows the data in the graph, but now number in the hover tooltip.
I dont think its a format problem coming from the measuments in the influxDB, this is a print of the measurements:
select * from “dht22-hum” limit 2
select * from “dht22-temp” limit 2
select * from “temp-ds18B20” limit 2
select * from kg limit 2
select * from “temp-onboardOS” limit 2
