Please add RPi MQTT Topic ~/memory_load in percentage

[thijselblaso]

First of all thanks for this! I use it for all my pi's!

I like to have an MQTT topic with memory load in percentage. Is that possible?

[ironsheep]

@thijselblaso do you mean a separate topic for memory used vs. free? Currentlhy we have these topics:

?

[thijselblaso]

@ironsheep yes, as a separate topic. I know that there is a memory attribute but I can not make a sensor out of it. I tried to separate the attribute memory in only used RAM in percentage with a sensor template in HA, but I can not make it work. I have a screenshot of my lovelace dashboard. The first one is my unraid server with glance integration. The MQTT server and pihole are raspberry pi's. What I'm missing there is the current used RAM

@thijselblaso yes, this shouldn't be too hard. GImme a week or so...

[thijselblaso]

@ironsheep Thank you, I appreciate it!

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)}}"

[ironsheep]

Added new sensor. Update appears in v1.7.3 and later.

(Pardon the Pitre suffixes that's the name of my RPi!)

Changes commited and appear in v1.7.3 and later
