Cisco OID Temperature sensor card

1

Hello to all,
I am new to HA and trying to learn what I can.
If you can help me with something it would be much appreciated.

I have a Cisco 3750 and I would like to have a graph to show the temperature via SNMP with the OID.

I was able to find the OID after search on the web and the OID tester to be 1.3.6.1.4.1.9.9.13.1.3.1.3.1005

Paessler SNMP Tester - 20.2.4 Computername: MYS Interface: ()
5/2/2022 12:42:50 AM (5 ms) : Device: 192.168.1.123
5/2/2022 12:42:50 AM (9 ms) : SNMP v2c
5/2/2022 12:42:50 AM (12 ms) : Custom OID 1.3.6.1.4.1.9.9.13.1.3.1.3.1005
5/2/2022 12:42:50 AM (20 ms) : SNMP Datatype: ASN_UNSIGNED
5/2/2022 12:42:50 AM (23 ms) : -------
5/2/2022 12:42:50 AM (26 ms) : Value: 37
5/2/2022 12:42:50 AM (29 ms) : Done

The card I am trying to add is:

platform: snmp
name: 'Poseidon Temperature'
host: 192.168.1.123
baseoid: 1.3.6.1.4.1.9.9.13.1.3.1.3.1005
community: 'public'
version: '2c'
unit_of_measurement: '°C'
value_template: "{{ value.split(':')[1].split(' ')[0] }}"

but I am getting No card type found & No card type configured.

Does anyone have any idea?

Thank you!

That’s not a valid card configuration, it’s a sensor.

You should put this in your configuration.yaml:

sensor:
  - platform: snmp
    name: 'Poseidon Temperature'
    host: 192.168.1.123
    baseoid: 1.3.6.1.4.1.9.9.13.1.3.1.3.1005
    community: 'public'
    version: '2c'
    unit_of_measurement: '°C'

Restart Home Assistant afterwards.

That value_template doesn’t look right. I suggest dropping it for now. If the state of the sensor is formatted incorrectly, post it and we can take a look at fixing it.
Open your Home Assistant instance and show your state developer tools.

Sir you are awesome! :metal:

Okay so first we cant put the code directly to the card but on the configuration.yaml and then restart the server.
Second I tried with the sensor.yaml and then do the include sensor.yaml on the configuration but didnt do the restart of the server.

One more question:
Is it possible somehow to generate an history average per week?
I have a powermonitor for example and I have two graphs 5days and 30days, but when I try to do the same with this it doesnt show me the sensor on the list.

Thanks again!

If you mean long-term statistics (statistics graph card), you’ll need to add state_class: measurement to the sensor. Platform snmp does not support this directly, so you’ll need to use customize.yaml:

sensor.poseidon_temperature:
  state_class: measurement
  device_class: temperature

The click “location & customizations” under “YAML configuration reloading” in Sever controls.
It probably won’t be available immediately, you’ll need to wait for an hour or so.

Aha!
So to make sure I understand it correctly.
1- Create the customize.yaml file to the config folder of HA
2- paste the code you send
3- edit the configuration.yaml file and add the code
customize: !include customize.yaml
4- restart again HA server
5- wait 2-3h for it to gather data
6- then go to dashboard and create a new card

type: statistics-graph
entities:
  - sensor.poseidon_temperature
chart_type: line
stat_types:
  - mean
title: Week
days_to_show: 7

correct?

It needs to be under homeassistant like this:

homeassistant:
  customize: !include customize.yaml

Other than that, I think you got it right.

7

lost you there,
under homeassistant? is this code still in the configuration.yaml?

8

Yes, it is in configuration.yaml.
But the customize key needs to be under the homeassistant key (mind the indentation).

9

excellent then!
let me try that.

I assume if I want to have clean code I can place the code of the sensor to the sensor.yaml file and do include in the configuration.yaml file correct?
Does this needs also to be under the umbrella of “homeassistant:”?

10

Correct.

Nope, sensor is a top-level key.

If you want to know more, I suggest that you read this:
