SD-Card - Value of type "string" is not suitable for value type "Numeric (unsigned)". Value ""

[sciensys]

NOT issues of the script or template.

But, if you get value like the following, when trying to get value from your SD-Card:

Value of type "string" is not suitable for value type "Numeric (unsigned)". Value ""

This means you get empty value, cause you do not have the device, described in raspberrypi.sh
To correct, you should get console at zabbix-agent side and check you device name,
perform the command:

df -P -B1

check your SD card path, for example you will see:

overlay 122808967168 181596160 116341682176 1% /

then replace device path everywhere, where process SD-Card path in raspberrypi.sh:

before: df -P -B1| grep /dev/root | tr -s " " | cut -d " " -f 4

after: df -P -B1| grep overlay | tr -s " " | cut -d " " -f 4
