Looking for a way to shutdown Firewalla GOLD in a remote power outage

As the title states I have a Firewalla Gold which is attached too a a PDU unit which is on a UPS, I have various equipment which is also attached too. 

I have x2 HP Gen 8 Micro servers running Hyper V with various VM's, I have x2 Raspberry Pi's, A QNAP NAS and a couple of smart home hubs.

The Smart home hub has a power detection sensor attached so that if the device is on battery for 10 minutes then I will initiate a shutdown of above equipment, I have automated all of this and it seems to be working apart from on the Firewalla gold router.

For the raspberry pi's I am using the following command

 

"C:\Program files\puTTY\plink.exe" -batch -ssh 'username'@'hostname' -pw <Insert-Password-Here> sudo poweroff

It works for the raspberry pi's and I can get it to execute for the Firewalla gold but the problem comes after a certain time period passes I then get an access denied error, I am unable to log onto the Firewall with SSH or shut it down using the script until I then reset the SSH password, its like there is an expiry password set for the current password which is expiring after a period of time.

I am also very new to Linux\SSH so my knowledge in this area is quite basic, an idea I had was to maybe create another account that has sudo access that I can use to automate a shutdown if I need it.

  Firewalla does reset the ssh password once a while.  The best way is to use this to connect

  https://www.ssh.com/ssh/copy-id

  This will install your public key inside ssh, so it doesn't matter what the password is, you should be able to get in.

  Thanks, have managed to get it working using PowerShell and windows in built SSH after a bit of research online. you need to run a couple of commands from power shell.

  First run 'ssh-keygen' which will generate the public key in %userprofile%\.ssh

  Then run the following to push the key to Firewalla:

  'type C:\Users\<username>\.ssh\id_rsa.pub | ssh USERNAME@HOSTNAME 'cat >> .ssh/authorized_keys'' without the 'marks'

  Once you do above enter the password for the Firewalla and then test you can access without a password by typing ssh username@hostname - Connection is made without the need for a password.

  Thank you very much Firewalla for the guidance, now my gold can shutdown if there is ever a power outage!
