feature request: Open Weather Map select data

[azonneveld]

I'm using the OWM hardware for detecting expected rain and wind speeds (to close sunscreens if the weather turns bad).
This works fine, but the system is collecting a ton of data, and also it creates lots of devices.
The amount of data makes the database huge and slows down my system.

I would like to have an option to select which data is collected (f.i. only wind speed and rain for the next hour).

Could this be implemented?

Don't worry, your RPI can handle all this information with ease.
To have an idea how hard your RPI needs to work execute htop from the SSH connection.
Old Domoticz data are being deleted constantly to avoid cumulation of data. (cannot retrieve rigth now where it is explained)
If you worry about the growth of the database checkout this Domoticz Wiki page.
Change the bash script like this.

Code: Select all

#!/bin/bash
#Retrieve memory usage of the system in percentage
#MEMUSG=`free -m|grep "Mem"|awk '{print $3/($4+$3) * 100}'`
DISKUSG= `df -ht ext4 | tail -1 |awk '{ print substr($5, 1, length($5)-1) }'`
#save memory usage to domoticz, replace with you IP, Portnumber and IDX
#OUTPUT=`curl "http://192.168.1.3:8080/json.htm?type=command&param=udevice&idx=59&nvalue=0&svalue=$MEMUSG"`
OUTPUT=`curl "http://192.168.1.3:8080/json.htm?type=command&param=udevice&idx=59&nvalue=0&svalue=$DISKUSG"`

Regardless of the performance issue: don't store/use data which is not needed, it is a waste of a, b, c, etc

In that case maybe Buienradar plugin collects less data.
It shows you (amongst others) Is it raining, Possible rain, Sunpower and Wind and has a total of 16 sensors.
But even then: Times of Pentium processors and 128G harddisks are over.

Maybe weerlive gives you the information you need.

I tried weeronline, but it is not accurate (enough).

Anyway, I already build my own OWM implementation.

I stopped using OMW. At my location, Visual Crossing uses the same local station as OMW. For my other wishes I use the janpep script
