Synology DiskStation 218+ monitoring via SNMP (new binding used)

Hello to everyone!
I would like to show how to configure Synology DS 218+ for SNMP monitoring and bind it to openHAB. First of all, I want to thank @MikeTheTux for his excellent explanation. I based my configuration on his post synology-diskstation-monitoring-via-snmp and made some changes.


  1. Enable SNMPv2c in DiskStation and set community to “public”.
  2. Install OpenHAB SNMP Binding ( NOT SNMP1 Binding).
  3. Install JavaScript and Map transformation service.

I’m not used all Synology OIDs, only what I need. So, if you want to add something else you are welcome. This is a link to Synology MIB Guide.

Cheers! :wink:


Wauw :grinning:

Thanks for the credits :crazy_face:
Unfortunatly I migrated mine almost the same time in parallel :nerd_face:

In addition to the post above, I came to the following different solution:

In order to reduce the load of the system I made 3 different SNMP things with different cycle times. Thereby I grouped the Channels according to their update frequency:

Thing snmp:target:snmpNAS10 [ retries="2", hostname="w.x.y.z", protocol="v2c", port="161", refresh="10", community="public", timeout="1500" ] {

Thing snmp:target:snmpNAS60 [ retries="2", hostname="w.x.y.z", protocol="v2c", port="161", refresh="60", community="public", timeout="1500" ] {

Thing snmp:target:snmpNAS1800 [ retries="2", hostname="w.x.y.z", protocol="v2c", port="161", refresh="1800", community="public", timeout="1500" ] {

The SMART attributes I modeled as switch as follows:

Type switch : Synology_SMART_Raw_Read_Error_Rate1        [ oid=".", mode="READ", datatype="STRING", onvalue="OK", doNotLogException="true", exceptionValue="OFF" ]

Reporting of Synology_System_upgradeAvailable I also needed to change, because it was also reporting Connecting(3), Disconnected(4) & Others(5)

rule "Synology smaller"
    Item Synology_System_upgradeAvailable changed
    if ( triggeringItem.state == UNDEF )
        Admin_Notify.sendCommand( + " changed to UNDEF")
    else if ( triggeringItem.state != NULL )
        val Integer value = Float::parseFloat(triggeringItem.state.toString).intValue
        val Integer limit = Integer::parseInt(transform("MAP", "",                  
        if ( (NotifyLocked.contains( == false) &&
             (value < limit)
            Admin_Notify.sendCommand( + ": " + value)
        else if ( value >= limit )

Thanks Form Your Great implementation, This is exactly what i am loooking for. Before i Start Working on that, one quick question.
When i try to install the snmp Binding i find only one

SNMP Binding
binding-snmp1 - 1.13.0

Is this the right one?

Hello. This binding is an old one… You must use the new version binding-snmp. If you cannot see it on your list maybe it is a time for upgrading your openhabian version? :slight_smile: For the old binding, you can use the tutorial of @MikeTheTux.

Thanks, after some trouble while updating I managed to update to OH2.5 now and got the correct binding now:

SNMP Binding
binding-snmp - 2.5.3

Now digging into the SNMP implementation :slight_smile:


I implemented all the .items, .things, .map etc. IT works pretty fine for me. Thanks for sharing that!

Nevertheless I have 2 issues which i was not able to fix so far:

  1. some of the transformations seem not to work, so for example Synology_System_SystemStatus shows me “1” instead of “Normal”.

  2. The calculation for Synology_RAID_RaidUsedSize seems not to work, it gives me no value back.

Any ideas? Thanks for any hints.

  1. Maybe you forget to add an appropriate mapping file for transformations. In my case, I used with the values of 1 for Normal and 2 for Failed.
  2. It works, but it takes some time to calculate the value if there is no change in the RAID volume. Try to add some files to your NAS and take a look if the value changed.
    Hope it helps :slight_smile:

Hi all, Just a quick question - I/m getting a number of telegrams to upgrade but once logged into my NAS there is nothing to upgrade. Any advice.

[30.09.20 23:44]
Message, Synology_System_UpgradeAvailable changed to 3

[30.09.20 23:47]
Message, Synology_System_UpgradeAvailable changed to 3

[01.10.20 15:06]
Message, Synology_System_UpgradeAvailable changed to 3

I do have the same behaviour with my DS214play and disabled the message. I am ok with that.

Hello. Sorry for the late reply. Here is my implementation of this rule. It only sends a message when an update is available

  rule "Synology upgrade available"
    Item Synology_System_UpgradeAvailable changed
    if ( triggeringItem.state != NULL )
        val Integer value = Integer::parseInt(triggeringItem.state.toString)
        if (value == 1)  telegramAction.sendTelegram("Synology System upgrade available")

Hi MikeTheTux,
thanks for your work on the SNMP / Synology solution.
I assume that this version will also work with openHAB 3.1. - right?!
Is there a repo with the complete solution, especially your Thing definitions
(“3 SNMP things with different cycle times… grouped the Channels according to their update frequency”)?

Thanks in advance!
