You need to get smartmontools to run smartctl command:
apt install smartmontools
or
compile from source
git clone https://github.com/smartmontools/smartmontools.git
cd smartmontools/smartmontools
./autogen.sh
./configure --with-nvme-devicescan
make
sudo make install

Before downloading and running the script you can check the script hash:

wget -qO- https://diskcheck.monster/smart.sh | md5sum | awk '{print $1}'
d300e269f1c9b6df241ac14d3d5e9954

wget -qO- https://diskcheck.monster/smart-test.sh | md5sum | awk '{print $1}'
6bc155992975d2a50046d0ad2cb6b7c4

Before downloading and running the script you can check if script verification was successful:

wget -qO- https://diskcheck.monster/smart.sh | [[ "$(md5sum | awk '{print $1}')" = "d300e269f1c9b6df241ac14d3d5e9954" ]] && echo "Verification of script was successful." || echo "Verification of script failed."

wget -qO- https://diskcheck.monster/smart-test.sh | [[ "$(md5sum | awk '{print $1}')" = "6bc155992975d2a50046d0ad2cb6b7c4" ]] && echo "Verification of script was successful." || echo "Verification of script failed."

Downloading and running the script:
wget -qO- https://diskcheck.monster/smart.sh | sh
Before each run of script smart.sh you should also short test your disk(s):
wget -qO- https://diskcheck.monster/smart-test.sh | sh
This script will verify if the hash of script smart.sh is correct and only then will run smart.sh (you need to manually download verify-and-run.sh and smart.sh, because each time we update smart.sh the hash will change):
wget -qO- https://diskcheck.monster/verify-and-run.sh | sh
Run cron once a day:
crontab -e
0 0 * * * wget -qO- https://diskcheck.monster/smart.sh | sh && wget -qO- https://diskcheck.monster/smart-test.sh | sh
