Hi,
The update entity doesn't work. I'm in version 0.9.1 and it still tells me 0.8.9.

However, if I look at the information in rpi-mqtt-monitor, I am in version 0.9.1.

The update entity image is missing. If I connect to the image link, it tells me "Folder not found".
I'm using a local image in the meantime.

Is it possible to also monitor the RSSI (WiFi Signal level)?

Hi. I've installed the script on a Ubuntu 22.04 OS. The cpu temperature isn't available when I try running below cat. Any idea why it is not displaying?? I am using a Beelink mini pc.

The service examples in the Readme reference a service file called rpi-cpu2mqtt.service, however the filename in the distribution seems to have been changed to rpi-mqtt-monitor.service

Examples should read
sudo cp rpi-mqtt-monitor.service /etc/systemd/system/ ; sudo systemctl enable rpi-mqtt-monitor.service
and
sudo service rpi-mqtt-monitor start ; sudo service rpi-mqtt-monitor status
respectively

Tried both manually installing and using the script. Fails to run with a divide by zero error. Thoughts?

Hello,
i use your script with Home Assistant. It's working fine :)
But HA has a naming convention that the Hostname should not be in the Entity name.

suggestion:
provide an HA Version of your script and remove "hostname" from the Description lines.
data["name"] = hostname + " CPU Usage" ...
Thanks

Naming of MQTT Entities
https://rc.home-assistant.io/integrations/mqtt/

Warning Message in home-asssistant.log
[homeassistant.components.mqtt.mixins] MQTT entity name starts with the device name in your config {'state_topic': 'mqtt-monitor/pi-alarm/uptime_days', 'icon': 'mdi:calendar', 'name': 'pi-alarm Uptime', 'unique_id': 'pi-alarm_uptime_days', 'unit_of_measurement': 'days', 'device': {'identifiers': ['pi-alarm'], 'manufacturer': 'Raspberry Pi', 'model': 'Raspberry Pi 4 Model B Rev 1.2\x00', 'name': 'pi-alarm', 'sw_version': 'Debian GNU/Linux 12 (bookworm)\n', 'connections': []}, 'state_class': <SensorStateClass.MEASUREMENT: 'measurement'>, 'force_update': False, 'encoding': 'utf-8', 'enabled_by_default': True, 'payload_available': 'online', 'payload_not_available': 'offline', 'qos': 0, 'availability_mode': 'latest'}, this is not expected. Please correct your configuration. The device name prefix will be stripped off the entity name and becomes 'Uptime'

Is it possible to send various (MQTT) messages from Home Assistant back to the Pi?

I don't know if it is because I use FR locales but check_cpu_load won't work as it should.
Uptime returns 0,91 instead of 0.91

To fix it, change line 27 from this :
cpu_load = p.split("average:")[1].split(",")[0].replace(' ', '')
to that to change "," in "." :
cpu_load = p.split("average:")[1].split(", ")[0].replace(' ', '').replace(',', '.')

When I change the config, I need to stop and start the service. It would be nice, if the config is reloaded on each run.

Hi, thanks for a fantastic tool. I realise it's pretty much static data, but it would be great if the monitor were able to send the ipv4 and/or ipv6 address of the pi via MQTT.

Hello

Thanks for the good tool, I was able to run it on my TV box running Armbian.
But I had to make an edit because not all processors have vendor information in them; receiving the manufactory fails with an error.

Could you add a check for this situation or provide an alternative option for obtaining data, for example, use model name instead of vendor.

Below is the error trace:

Hello, I use rpi as NAS and have raid0 array. How should I modify the .py script to display (or add mqtt message for) external storage?

/dev/md0 on /RAID3T

Thanks, Jan

Would it be possible to have a switch similar to the power off but only turn off/on the display. I am currently using the shell command 'xset -display :0 dpms force off' or 'xset -display :0 dpms force on'.
The mqtt option would avoid the ssh authentication issue.
I am trying to automate the touchscreen connected to the pi.
Thank you

Hi whats the swap?

A shutdown button that can shutdown the RPi on demand.
Simular to #29 but for shutdown.

Im running RPi4 with Ubuntu fpr RPI and this is the error Im getting. Any idea what is wrong?

Here's an example output of free as-is:

              total        used        free      shared  buff/cache   available
Mem:        8132632     5525592      156444      292000     2450596     2232356
Swap:             0           0           0

I can get it to work when removing the -t and filtering by Mem:

free | grep -i mem | awk 'NR == 1 {print $3/$2*100}'

For Swap, I also get the same issue as #11 (Division by Zero).

A binary sensor that shows if the git repository is up to date.

I'm searching my logs and so many clients have random names generated by not using clientID, it would be good to be able to fix it so I can parse logs better.

Can I suggest changing uptime, to a last boot timestamp. That way Home Assistant will automatically set the time formatting.
Like this:

Mqtt auto discovery parameters :

{
  "name": "Last Boot",
  "state_topic": "xxxx",
  "device_class": "timestamp",
  "value_template": "{{ as_datetime(value) }}",
  "unique_id": "xxxx",
   etc,
   etc
  }
}

I get the following error:

Hi

It would be nice to be able to use the HA API instead of MQTT to avoid the need to expose MQTT port for remote use ;)
That lib should make it quite easy to implement (https://pypi.org/project/HomeAssistant-API/) I guess :)

Thanks

Vincèn

A restart button that can restart the RPi on demand.

Hi,thanks for your job,i'd like (if possible) to have PIR sensor value (connected in GPIO) via mqtt...

When there are changes in the local git and the code cannot be updated, the update script now succeeds.

A update entity that makes use of #28 to display when there are changes and enabled a remote update.

Thanks for your job 😊

if I understand correctly rpi sends data every 5 minutes... is it possible to decrease the time?
