sensor.ssh

Generic SSH based sensor for Home Assistant

Version mantained forum

Login to a remote server via ssh, execute a command and retrieve the result as sensor value

To get started download

/custom_components/ssh/__init__.py
/custom_components/ssh/manifest.json
/custom_components/ssh/sensor.py

into

<config directory>/custom_components/ssh/

Example configuration.yaml:

sensor:
  - platform: ssh
      host: !secret proxmox_host
      name: 'NUC CPU Temp'
      username: !secret proxmox_user
      password: !secret proxmox_pass
      command: "sensors | grep 'Package id 0:' | cut -c17-20"
      value_template: >-
        {%- set line = value.split("\r\n") -%}
        {{ line[1] }}
      unit_of_measurement: "ºC"

Configuration Variables

name

(string)(Optional) Friendly name of the sensor

host

(string)(Required) The hostname or IP address of the remote server

username

(string)(Required) A user on the remote server

password

(string)(Required) The password for the account

port

(integer)(Optional) The port to ssh to Default value: 22

command

(string)(Required) The command to execute on the remote server

Considerations

The sensor utilises the pexpect library https://pexpect.readthedocs.io/en/stable/ which mimics a user logging into the remote server via ssh. This results in the output being formatted as output from a tty terminal. Check out the pexecpt documentation for the oddities this causes.

A sensor value can only by a maximum of 256 characters in length, therefore make use of the value_template to parse data larger than this.
