Energy manager connected to a smart meter, Values in a VD

[Mr Jack 10]

Just started with the HC2 and for sure completly new to LUA.
I already had an Iungo Energy manager to get the usage on electricity and gas from the smart meter, and also the water usage.
At this stage I managed to get a reponse from the energy manager, but didn't succeed to get the values for use in a virtual device.
 
I hope someone can give me a suggestion to put me in the right direction on how to get the values from the response.

That was what I had in mind to try.

Only one question what does the  end,5000)

Not shore what you mean by “what dose the end,5000).

If you mean what does it do. It’s part of the 5 second "setTimeout" delay function.

 

setTimeout(function()

                Your code to run after the delay (1000 = 1 second)

end,5000)

Have you tried to send request only?

 

HC2 = Net.FHttp('192.168.0.15') 

res, status, err = HC2:GET("/iungo/api_request/")

Hi cag014

 

Tried the following script:

 

HC2 = Net.FHttp('192.168.0.15') 

res, status, err = HC2:GET("/iungo/api_request/")

fibaro:debug(res)

fibaro:debug(status)

fibaro:debug(err)

 

No response at all and no error.

Stupid me. 

Completely missed the 2x  setTimeout(function() in your script John.

Get direct an error on the first

Sorry Jack looks like you can't use setTimeout in vertical devices.

I have edited the above code for you.

[Mr Jack 10]

 

when i built my own virtual device for energy reading, i remember it stopped after few minutes...

sadly, i don't remember what i did to correct it

 

looking at my code and comparing it to yours, i can see that i put the Net.Fhttp statement in an if clause, to avoid opening sockets continuosly:

Hi onesim,

 

I have created a new VD to test your code. 

There was only one bracket to much between the "if" and the "tonumber".

It's running now. Let's see if it stops, or stay running.

NP John,

It's a learning curve for me

I have now restructured the code first in a logical order, with still one fibaro:sleep moment.

Test is running. If it stops again, I activate the second sleep moment.

@onesim

It looks like your suggested code did the job.

The new created VD, although only with the "usage" value, worked since it started yesterday evening.

I just created the full script now, for all the values, like in the first VD.

At this moment the ony thing I can do is wait

[Mr Jack 10]

LOL

Firmware upgrade of the energy manager is messing up the values at Water flow and Water used.

There is a very technical unexpected solution to solve this.

It will be hard to guess what this solution is.

My VD never stopped since i starded it more than one month ago...

[Mr Jack 10]

VD is running like a charm with your suggested code. Thanks onesim.

 

Next step is to set the "usage" value to powerConsumption on double relay switch FGS222 to show the power usage in the Energy Panel

Version 1.3.

 

Added:

Total energy usages from the Smart Meter, minus the energy values from all z-wave devices with power metering, to get the total of the remaining non measured power consumption.

This calculated value is added to "power" of an unused relay input of a double fibaro switch. 

Now it is shown in the energy panel and the toal enegry usages without counting values double.

[emielstroeve 22]

this is the missing link! 

 

I'm working on adding a module to read-out the Smile P1 smart meter interface. I'm up to the point were I've already got the meter readings in a variable in the VD. Looking good!

 

ps. used the lua code of Robert Hekkers.

 

cheers

emiel

[Mr Jack 10]

Thanks Emiel,

With the help of this forum, it's members and Iungo, I was able to create this solution.

It took some time to create my first real lua code, but I like learning it this way.

Next challenge is already started. Get data via ModBus TCP IP.

EDIT:

It seems that I earned Stroomwafels

Hi Jack,

 

I buy also a iungo (light), and make a VD. Everything's works perfect.
If you have new futures, please share....

[Mr Jack 10]

Hi Twanve

 

Good choice the Iungo 

 

There is a new version,

In the new version the VD icon, a meter, will change based on the "usage" value.

 

-- Change Icon based on the usage value 10%,30%,50%,70%,90% and 100% of 7360 Watt 32Amp at 230V
--10% = 736W, 30% = 2208W, 50% = 3680W, 70% = 5152W, 90% = 6624W, 100% = 7360W

You need to download these, and add them to the icons for virtual devices. Then find the number of each Icon and change the icon numbers in the above code.

[twanve 18]

Yesterday the VD works great, but this morning the VD hangs, after stop en save it works again. Strange....

 

But those icons, I load the icons up in my VD number (595), but where can I find the icon numbers

I select one Icon in the VD, but nothing happens when the usage change.

 

Gr. Twan

 

ps; I have also sun panels, I must make new icons, with daylight I return power to the net

[Mr Jack 10]

Hi Twan

 

Right click on the Icon, and then clcik on inspect element. Then you will see in the right screen that opens the number of the icon for example

id="Icon vdevice_icon_118" 118 is then the number you need.

 

I am not sure what the value of "usage" will be when your solar panels return power to the grid. I asume that it will show as a negative value.

You can add more code to have icons displayed at the moment that you are delivering back to the grid.

 

Other suggestion could be that you use the 50% meter for 0 Watt consumed, and the icons 10% and 40% for delivering back and 70%, 90% and 100% for consumed power.

 

Added:

 

You can use the code below to get the Imported Power and Exported Power in kW. Multiply it by 1000 and you have watt's again.

 

L1Pimp=jTe.rv.propsval[8].value

L1Pexp=jTe.rv.propsval[9].value
