openHAB version:2.4
Hi I not getting the way how grafana work. So I like to ask you guys to help get me started
I posted on there froum but had no help.
So I using OpenHab to run my Sprinkler System when turn on it send data to influxdb as 1 with an time and 0 when it turn off with a time.
so what i like to do is use grafana to tell me how much water was give IN the time.
I have started an graph but shows just 1 every time it turn on and drops when it turn off
what I think with the youtube video’s I have watch that is something to do in Metrics
I have posted on there forum. I was going to measure volume from time turned on and off. No I don’t have an volumetric that’s why I want to use Grafana to do it for me.
Hi,
you need an Item that will count up your volumetric meter, or you use the integral function of grafana and correct the “1” by multiplying with the flow rate you currently have.
So either you set up a rule that adds a certain amount of volume to a counter every minute your sprinkler is running, or you graph the flow rate over time and integrate it.
