as a workaround you can use the following template sensor: ``` - sensor: - name: "pi4b memory usage" unique_id: pi4b_memory_usage unit_of_measurement: "%" icon: mdi:memory state: "{{(100-(state_attr('sensor.rpi_monitor_pi4b','memory')['free_mb']|float)*100 / (state_attr('sensor.rpi_monitor_pi4b','memory')['size_mb']|float))| round(2)}}" ```

I'm also having this issue
