This is a steemd fail-over script using steem-python. If the server is unreachable or has missed blocks (set by the threshold value), it will fail over to the backup server. If something is wrong there, the signing key is disabled. If enabled, an email will be sent by the sendnotice.py script.

I'm using Furion's steem-python because it has more features.
pip3 install -U git+https://github.com/Netherdrake/steem-python
But, you can use the official steem-python, it should work just fine.
pip3 install -U git+https://github.com/steemit/steem-python
git clone https://github.com/Jolly-Pirate/witness-failover.git
Run steempy addkey
Enter your Active PRIVATE key. Enter and confirm a passphrase for the wallet. Press ENTER to quit.
Check that your account and Active PUBLIC key are showing up in the wallet.
steempy listaccounts
The wallet is stored in ~/.local/share/steem/steem.sqlite, in case you want to remove it from your computer.
Go to the git cloned folder.
cd ~/witness-failover
Secure the files, they will contain sensitive information, and set execution permission.
chmod 700 witness_failover.sh sendnotice.py
Edit witness_failover.sh and sendnotice.py files with your own values.
If using Gmail's SMTP, test it first by running ./sendnotice.py test. If you get an SMTPAuthenticationError, go to https://accounts.google.com/DisplayUnlockCaptcha to allow the device then retry.
Start and enter a screen session: screen -S failover
Start the script: ./witness_failover.sh
Detach from the screen session with CTRL-a-d. This will leave it running in the background.
Reattach to the session with screen -r failover to monitor its status. If you want to terminate the script press CTRL-c, then type exit to close the screen session.
