Installed several (10) Nous A1Z plugs over the last weeks. Homeassistant slowed down due to high CPU load. I noticed the Nous plugs flooded the deconz log with sensor readings. Editing the DDF solved the problem
Changed min interval and reportable change and save the new DDF in /data/.local/share/dresden-elektronik/deCONZ/devices which reduces the flood of sensor readings. Maybe this isn’t the best solution?
