I have a standard openhabian setup up and running with some devices in my house.
- Platform information:
- Hardware: Raspberry Pi 3 b+
- OS: openhabian
- openHAB version: 2.3 stable
Recently,i have added some http items to address my hue dimmer switches and sensors.
My http.items has about 50 items with refresh rates ranging from 5000 to 60000. My http.cfg is smaller, about 30 items, with corresponding refresh intervals.
Now my http refresh service is using about 50 percent of the overall CPU time and the Java process iss almost always above 100 percent.
Once I hide the http.items the system goes back to normal. Otherwise I have a very high load average.
Could it be that this comes from items in the http.items file that are not registered in the http.cfg?
If that’s not a possible issue, what can I do to reduce the load by the http binding. Are 50 items already too much?
Some of the items like buttons and motion sensors just need a certain refresh rate (5000 in this case).
I have defined the items as posted in the tutorial on this forum.
Thank you so much and all the best,
