Hi dear community,
for about a year I am using an ECOWITT Wittboy with the integrated piezo and an external WH40 rain gauge.
I am using the core integration but I don’t think my issue is because if the integration.
From what I found so far is that the calculation for the “hourly rain rate” is different than for the other “rain rates”.
I really don’t like the term “rate” in this context because a “rate” is usually a value “per something” for me, for example mm/hour.
So what I also see in my data is that the other “rates” like daily or monthly work like the HA utility integration where you set a point when it is reset it starts counting from 0 again.
But the “hourly rain rate” from ECOWITT is “for the last hour”. So every time I get a value transmitted from that sensor it is the amount of rain from “now - 60 minutes”.
This might be a nice information but building a graph from it is IMHO totally useless.
And considering the same naming scheme if find it problematic to use a different definition of how that measurement works.
What I want to do is show graphs for various time ranges with Grafana and for this I think it would be best to have an amount of rain in the least possible interval. So in connection with InfluxDB I used the yearly sensor for now and “non_negative_difference” for that sensor to get reasonable results.
What I want to ask, is my problem real or do I misinterpret the use?
How do you use the “hourly rain rate” and if you draw graphs which sensors do you use for that?
For now I am going to try some extra HA utility sensors based on the yearly because what I am also missing is a total sensor just increasing to infinity like other integrations have, the yearly will be reset each year.
What I expect of an “hourly” sensor is that it is 0 at the start of each hour, which it is obviously not at 3am…
Here a rain gauge of a different weather station I run where I had to create the sensors in HA my self because I just a get an increasing total value from the station:
Sorry I couldn’t assist, but your implementation has inspired me to have a look at the utility meter, to do 15 min interval stats for my own gauge. Thanks…
