Today Vincent mentioned a link about mqtt and mikrotiks, i knew about addons, but not mqtt .. lets try this.

When you want to use MQTT with Mikrotik you have to install the iot package from extra_packages.

• Download correct package zip from ( https://mikrotik.com/download )
  • Download extra packages zip for your system
• Extract and use file upload
• Reboot your mikrotik

(i had to upgrade my firmware first, iot package was not build for my version)

Create a entry in IoT > Mqtt to your broker.

save below in a script ending with a .rsc extention, and upload in file manager

# Required packages: iot

################ Configuration #################
# Name of an existing MQTT broker that should be used for publishing, the one you just created
:local broker "10.1.0.17"

# MQTT topic where the message should be published
# i've got mine in a tree called mikrotik/switchtype/
:local topic "mikrotik/rb2011/topic"

############### System ###############
# You can create your own variables below
:put ("[*] Gathering system info...")
:local cpuLoad [/system resource get cpu-load]
:local freeMemory [/system resource get free-memory]
:local usedMemory ([/system resource get total-memory] - $freeMemory)
:local rosVersion [/system package get value-name=version \
    [/system package find where name ~ "^routeros"]]
:local model [/system routerboard get value-name=model]
:local serialNumber [/system routerboard get value-name=serial-number]
:local upTime [/system resource get uptime]

################## MQTT ###################
# create a message
:local message \
    "{\"model\":\"$model\",\
                \"sn\":\"$serialNumber\",\
                \"ros\":\"$rosVersion\",\
                \"cpu\":$cpuLoad,\
                \"umem\":$usedMemory,\
                \"fmem\":$freeMemory,\
                \"uptime\":\"$upTime\"}"

:log info "$message";
:put ("[*] Total message size: $[:len $message] bytes")
:put ("[*] Sending message to MQTT broker...")
/iot mqtt publish broker=$broker topic=$topic message=$message
:put ("[*] Done")

Import script using

import mikrotikmqtt.rsc

Todo’s:

Import is just @ import time, need to “cron” this?
