[Virtual Device] UPS Status

[Lambik 192]

Hi to you all!

This Virtual device can check values from an UPS connected to a Synology NAS (or even to any NUT-server, didn't check that).
The principle is simple. A Synology uses NUT (

) for communicating to an UPS and reporting to other Synology's.

With a Virtual Device you can setup a TCP communication on port 3493 and receive variables about the status of the connected device. I made a Virtual Device which you can use and made an icon to go with it.

Preparations
Synology Preparations:
First of all you need to prepare the Synology (the one where the UPS is connected to) to accept the HC2 to communicate:
- Log on In the DSM as admin and go to: Control Panel --> Hardware & Power --> UPS (tab)
- Check 'Enable network UPS server'
- Click on button 'Permitted DiskStations' and add in the pop-up window the IP-address of your HC2. Confirm with the 'OK'-button
- When the pop-up is closed, click on the 'Apply'-button.
Note: If you have Firewall enabled it is not necessary to add the 3493 port.

HC2 preparitions:
- Add three Global Variables called "VD_UPS_Instance" (to block more then one instances of the Virtual Device running and store status of communication), "VD_UPS_Battery_Lev" (for storing battery level) and 'VD_UPS_Battery_RT' (battery runtime in seconds)
- Import the Virtual Device (attached to this posting)
- Change the Virtual Device IP-Address setting to match the IP of your Synology/NUT-server
- Change the Virtual Device Port setting to match the TCP-communicationport of your Synology/NUT-server (should be 3493 in most cases)

Modding:
In the Virtual Device are variables which can be changed to your needs if necessary. If you want another value read from the UPS-server, check

for the different commands.
You can also use Telnet and use the command

You get a list of all variables available which van be used in the Virtual Device bij altering line 11 from the 'Check Battery Level'-button :

Also if you want more functions just copy the code to a new VD-button and change the variables of your choice.

The debug Window shows what the VD is doing. If everything is working to your satisfaction, you can disable the debug messages by setting 'false' to the line (4)

In the main loop you can find some additional info if needed.

If you suggestions, remarks or questions, don't hesitate to post. If I can I will help. Well, I will give it a try...

Nice little virtual device works here nice!

Only thing I would have is the current battery level set as the label or an auto refresh every minute?

But otherwise well done buddy!

[Lambik 192]

Thanx mate!

The reason I didn't do that is because anyone could make there own VD from the Global Variable. The update could be easily done by creating a scene which does the trick (see attachment).

Anyway, because this just the first version of the VD I will take your suggestion very serious. So I try to program your wish into the next version.

I will try to do this during this week and report here when done...

Thank you for responding, it's highly appreciated!

i changed the code to check using lua and removed a lot of the testing labels would rather just see the percentage drop 100% 99% etc...

But the base of the code i than you for very much!

[Lambik 192]

and removed a lot of the testing labels

You can set the variable debug = true to false, so debug-messages are disabled in the debug window.

I take your idea and add some code you're asked for. Also I will try to make some icons which correspond with battery levels.

Load UPS

Thanks.

Hi,

This is another solution:

Thanks for the link!

They have an other approach. They made a linux script to send SMTP values to the HC2.

It's a way to do it but you have to ssh into the Synology and I want to keep it simple without modding the Synology.

Although it has some interesting code I can use as example for later projects...

Posted V0.3.

Edited first post.

[sebaszz 2]

i have 2 questions:

 

- I have set the icon id's in the main loop. Somehow when the main loop sent the pressbutton command it will also change icon to the standard virtual device icon? is this normal?

 

- the virtual device was somehow stuck because the global variable "VD_UPS_Instance" was set to 2. After changing manually to zero it restarted again. 

 

For the rest many thanx for this virtual device!

To answer your questions,

1 - change the button icons to the one with the magnifying glass

2 - I also noticed that. Happens when updating your HC2 to a newer firmware.

thank you that explains all

is there also possibility to check the list thru the vd?

changed the tcp command without succes to list var in the hope expecting the entire response in the debug view

[Lambik 192]

You can do a telnet session connecting your Synology on port 3493.

Please login or register to see this code.

Then give command:

LIST VAR UPS

(be aware you use capital letters)

 

Then you see all of the variables and their actual values.

Thanks for reporting!

 

For now I wouldn't implement this, unless there will be a solution to start up the HC2 again. A Wake On LAN would be nice...
