sensor.ssh

Generic SSH based sensor and switch for Home Assistant

• Tested and verified using Home Assistant 0.103.6

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

Switch: Login to a remote server via ssh, execute specific remote commands to perform switch on, off, and status commands

To get started download

<config directory>/custom_components/ssh/

Example configuration.yaml:

sensor:
  - platform: ssh
    scan_interval: 3600
    host: 192.168.100.100
    port: 2222
    name: 'My Sensor Name'
    username: !secret device-username
    password: !secret device-password
    key: !secret REALLY-LONG-SSH-HASH
    command: "sensors | grep 'Package id 0:' | cut -c17-20"
    value_template: >-
        {%- set line = value.split("\r\n") -%}
        {{ line[1] }}
    unit_of_measurement: "ºC"


switch:
  - platform: ssh
    scan_interval: 3600
    host: 192.168.100.100
    port: 2222
    name: 'My Switch Name'
    username: !secret device-username
    password: !secret device-password
    key: !secret REALLY-LONG-SSH-HASH
    command_on: '/usr/local/sbin/remote-command'
    command_off: 'echo off'
    command_status: 'echo off'

NOTE: Above Switch example will always indicate off, since status command's return value will equal 'off'

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

key

(string)(Required) SSH remote host key to match.

command

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

command_on

(string)(Required - Switch Only) The command to execute on the remote server when the switch is activated

command_off

(string)(Required - Switch Only) The command to execute on the remote server when the switch is deactivated

command_status

(string)(Required - Switch Only) The command to execute on the remote server to determine switch on/off status

Considerations

The sensor utilizes a paramiko client, a python implementation of the ssh v2 library. Documentation can found at http://docs.paramiko.org/en/stable/api/client.html

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.
