• HS110 wifi power plug
• For simple setup using clear text passwords:
  • plink from putty-tools
  • install with sudo apt install putty-tools
• For recommended setup using ssh with a key file:
  • ssh with a private key generated by ssh-keygen and its public key pasted to the device's ~./ssh/authorized_keys file
  • see man ssh and man ssh-keygen for further help
• softScheck “tplink_smartplug.py” from https://github.com/softScheck/tplink-smartplug/tree/master

Copy the files hs110_off, hs110_on, mks_poweroff , shutdown_sv06 and tplink_smartplug.py into a single directory and make them executable by using chmod +x *.

Now you should be able to shutdown and power off the device using clear text passwords by executing shutdown_sv06.
To power it back on, execute hs110_on.

To use passwordless login (recommended), you need to generate a key file.
You can either use putty's plink or standard ssh for that, but the keys need to be generated differently.

First create the “.ssh” directory (if not already existing)

• mkdir -p ~/.ssh ; chmod 700 ~/.ssh

For plink:

• Use puttygen to generate the key
  Example: puttygen -t ed25519 -f ~/.ssh/printerkey
• Use puttygen again to generate and display the accompanying standard ssh public key
  Example: puttygen ~/.ssh/printerkey -L
• See man puttgen for further details

For standard ssh:

• Use ssh-keygen to generate the key
  Example: ssh-keygen -t ed25519 -f ~/.ssh/printerkey
• Use cat ~/.ssh/printerkey.pub to display the ssh public key
• See man ssh-keygen for further details.
• Set the PLINKCMD variable in mks_poweroff to ssh

Then

• Make the keyfile unreadable to other users: chmod 600 ~/.ssh/printerkey
• Adjust the PLINKKEY variable in mks_poweroff so it points to your private key file (~/.ssh/printerkey in these examples)
• Empty the PASSWORD variable in mks_poweroff
• Log into the device using ssh and add the public key to ~/.ssh/authorized_keys:
  • cat » ~/.ssh/authorized_keys
  • Paste the public key line and press CTRL+D to quit

Now you should be able to shutdown and power off the device without clear text passwords.

The files:

#!/bin/sh
python tplink_smartplug.py -t 192.168.1.60 -c off

#!/bin/sh
python tplink_smartplug.py -t 192.168.1.60 -c on

#!/bin/bash

# Install plink (allows passwords given on commandline)
#   apt install putty-tools
# To use a ssh key:
#   Adjust PLINKKEY so it points to your private key
#   (generated with "puttygen" when using putty, or with "ssh-keygen" for default ssh)
# Using ssh instead of plink is possible when using a ssh key instead of a clear text password:
#   Set PLINKCMD=ssh

# === best practice is using a PLINKKEY instead of a cleartext PASSWORD ===
