Troubleshooting deCONZ unavailability and high CPU loads

Meanwhile: I changed the recorder ‘commit_interval:’ to 600 to see if it has a positive effect on the stability by reducing the writes. I recalled that I had this set to 60 before, but had it commented out at the moment. I created a CPU IO Wait sensor to keep track of the IO and report it in my deCONZ monitor command_line: - sensor: name: CPU IO Wait command: top -b -n1 | grep ^CPU | awk '{printf("%.0f"), $10}' scan_interval: 3 unit_of_measurement: "%" value_te…
