What I want to achieve, functionally:
Have an alert sent out when the usage on one of my phases (3) is over 20A for 10/20/30s.
Why? To give me a chance to lower my power consumption before the main fuse blows. I have an electric car and load balancing on the EVSE is (not) yet working, so this will have to do for a while.
Bonus would be that Grafana could trigger an HTTP URL to lower the car charger, but that’s maybe later.
I am from the old ages and I can’t seem to get the new way of Flux, but for now everything I wanted to get working works except for alerting.
I got to the alerting dashboard and thought “well, this can’t be that hard” but I get some errors:
Why does it show Alert condition red when I do a preview although the Amps are well below 20?
What is wrong with the alert since it shows health yellow?
