Complete step-by-step guide for integrating Didactum monitoring devices and sensors into Zabbix 6.x LTS via SNMP – including template import, item configuration, triggers, and OID reference.

• Zabbix version: 6.x LTS
• Protocol: SNMP v1/v2c/v3
• Devices: Didactum Monitoring System 100 / 300T / 500T / 550T
• Sensors: Temperature, leakage, humidity, door contact, smoke

Zabbix server

• Zabbix 6.x LTS installed and accessible
• Packages snmp and snmp-mibs-downloader installed
• UDP port 161 (SNMP polling) and UDP port 162 (SNMP traps) opened in the firewall
• Zabbix process SNMPTrapper enabled (for trap reception)

Didactum device

• Monitoring System 100T / 300T / 500T or 550T
• Network access to the Zabbix server
• SNMP enabled (v1/v2c or v3)
• MIB file available in the web interface

  Web frontend: 192.168.1.10/zabbix

Step 1 – Open web interface

Open in browser: 192.168.1.50 (adjust Didactum device IP)

Step 2 – Open SNMP settings

System Settings → SNMP

Step 3 – Enter the following values

SNMPv3 settings (optional, increased security)

Step 4 – Save settings

Click the save icon. Then test SNMP from the Zabbix server:

snmpwalk -v 2c -c didactum_mon 192.168.1.50 .1.3.6.1.4.1.46501

If lines with OID values appear, SNMP is configured correctly.

Step 1 – Download MIB from the Didactum web interface

System Settings → SNMP → "Download MIB file" → didactum.mib

Step 2 – Install MIB on the Zabbix server

# Install SNMP tools (if not already installed)
sudo apt install snmp snmp-mibs-downloader -y

# Copy MIB file
sudo cp didactum.mib /usr/share/snmp/mibs/

# Adjust SNMP configuration
echo "mibdirs /usr/share/snmp/mibs" >> /etc/snmp/snmp.conf
echo "mibs ALL" >> /etc/snmp/snmp.conf

# Test with MIB name
snmpwalk -v 2c -c didactum_mon -m ALL 192.168.1.50 DIDACTUM-MIB::sensorValue

Step 1 – Navigation

Configuration → Hosts → Create Host

Step 2 – Fill in the “Host” tab

Step 3 – Fill in the “Macros” tab

Store the SNMP community string here as a macro:

For SNMPv3 additionally:

Step 4 – Save host

Click Add.

The host now appears in the host list. The icon next to “SNMP” turns green once the connection works (may take a few minutes).

Step 1 – Download official Didactum template

Didactum provides a free template. Download sources:

• Directly from Didactum: https://www.didactum-security.com → Downloads → Zabbix Template
• Filename: zbx_didactum_template.xml

Step 2 – Import template into Zabbix

Configuration → Templates → Import (top right)

Select the file zbx_didactum_template.xml, leave all options enabled, click Import.

Step 3 – Assign template to the host

Configuration → Hosts → Didactum-Monitor-01 → Tab "Templates"
→ "Link new templates" → search for "Didactum" → select template → Add → Update

Step 4 – Check data

Monitoring → Latest data → Host: Didactum-Monitor-01

After a few minutes, the first measured values of all connected sensors will appear.

If the Didactum template is not used or additional sensors are to be integrated, items can be created manually.

Navigation

Configuration → Hosts → Didactum-Monitor-01 → Items → Create Item

Item: Temperature value

Item: Temperature sensor status

Item: Water sensor / leakage

Create value mapping (for leakage and status sensors)

Administration → General → Value mapping → Create value map

Name: Didactum Sensor Status
  0  →  OK / Dry
  1  →  ALARM / Water detected
  2  →  No connection

Name: Didactum Leak Status
  0  →  Dry
  1  →  Water detected

Define triggers to specify when Zabbix generates an alert.

Navigation:

Configuration → Hosts → Didactum-Monitor-01 → Triggers → Create Trigger

Trigger: Temperature too high

Trigger: Temperature critical

Trigger: Leakage detected

Trigger: Sensor not reachable

Note on thresholds:

• The values 28°C and 35°C are examples.
• Adjust them to the actual requirements of your infrastructure (e.g. server room: warning from 25°C, critical from 30°C).

All Didactum OIDs start with .1.3.6.1.4.1.46501 (older firmware) or .1.3.6.1.4.1.39052 (newer models). The sensor ID is appended at the end.

OID fields per sensor

Sensor types and corresponding OIDs

Determine sensor ID:

In the Didactum web interface under System tree → select sensor → Details. The displayed ID is appended to the end of the OID.

MIB prefix per model:

Older devices use .1.3.6.1.4.1.46501, newer ones may use .1.3.6.1.4.1.39052. Refer to the MIB file of your device for the exact OIDs.

In addition to active polling, Zabbix can also receive SNMP traps that the Didactum device sends automatically in case of an alarm.

Step 1 – Install snmptrapd

sudo apt install snmptrapd snmptt -y

Step 2 – Configure snmptrapd

sudo nano /etc/snmp/snmptrapd.conf

Enter the following content:

authCommunity execute,log,net didactum_mon
traphandle default /usr/sbin/snmptthandler

Step 3 – Configure Zabbix server for trap reception

sudo nano /etc/zabbix/zabbix_server.conf

Find and enable the following lines:

SNMPTrapperFile=/tmp/zabbix_traps.tmp
StartSNMPTrapper=1

Step 4 – Restart services

sudo systemctl restart snmptrapd
sudo systemctl restart zabbix-server

Step 5 – Create trap item in Zabbix

Configuration → Hosts → Didactum-Monitor-01 → Items → Create Item

Step 1 – Configure media type

Administration → Media types → Email → edit

Step 2 – Add email address for admin

Administration → Users → Admin → Media → Add
  Type: Email
  Send to: [your@email-address.com](mailto:your@email-address.com)
  When active: 1-7,00:00-24:00
  Severity: enable all

Step 3 – Create action for trigger alerts

Configuration → Actions → Trigger actions → Create action

Message template (Subject / Message)

Subject:
ALARM: {TRIGGER.NAME} on {HOST.NAME}

Message:
Time:       {EVENT.DATE} {EVENT.TIME}
Host:       {HOST.NAME} ({HOST.IP})
Trigger:    {TRIGGER.NAME}
Severity:   {TRIGGER.SEVERITY}
Status:     {TRIGGER.STATUS}
Item:       {ITEM.NAME} = {ITEM.VALUE}

Test SNMP connection

# Simple connection test
snmpget -v 2c -c didactum_mon 192.168.1.50 sysDescr.0

# Retrieve all sensor values
snmpwalk -v 2c -c didactum_mon 192.168.1.50 .1.3.6.1.4.1.46501.5.1.1

# Retrieve a single temperature value
snmpget -v 2c -c didactum_mon 192.168.1.50 .1.3.6.1.4.1.46501.5.1.1.7.101001

Check Zabbix Latest Data

Monitoring → Latest data → Filter: Host = Didactum-Monitor-01

If values appear and the timestamp updates, polling works correctly.
