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

Mr Jack

Asked by Mr Jack,

Question

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.

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

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

    Love the Iungo as a gateway for electricity, gas and water measures, and the capability for integrating EV charging stations and heat pumps.

    Hi Jack,

     

    Do you have the solution for the VD, that stops reporting after xx minutes.

    My VD stops after 40 minutes, when I open and save it's ok.

     

    I use no other meters, so my code is not so big.

    Hi Twan

     

    I had the same issue in the beginning.

     

    The first part of the code needs to be the following

     

    if(HC2==nil) then
    HC2=Net.FHttp('xxx.xxx.xxx.xxx'); --IP Address Iungo
    else

     

    and then at the end of the code you need to add:   end

     

    See the code you posted with the changes below

    Sorry HC2 in the first line must be smartmeter

    My response was to quick, and then you make mistakes.

    Please login or register to see this image.

    /emoticons/default_icon_redface.gif" alt=":oops:" /> or forget a part. Sorry

    You already found the correct solution.

    Now it will stay up and running.

    It might stop when you are working on an other VD which runs into an error. Don't know why

    But normaly it will not freeze

    Yesterday I upgrade the iungo with a 3 phase consumption meter for Solar panels.

    This meter works with a S0 bus, to read the puls for one kWh.

     

    Now I will show the consumption for this meter with a formula. The consumption output ("Meterstand") give me "21.22383456677899"

    Is it possible, to show the output with 2 decimals?

     

    I tried this; (from

    topic), but give a error with debug

     

    fibaro:call(596, "setProperty", "ui.Label2.value", string.format ( "%6.2f", Meterstand.. " kWh"));

    It's so simple for a Lua expert...

    Small improvement, made the VD more reliable, and keeps it running while working on other VD's

    Changed the IP address of the HC2 to 127.0.0.1, 1111

    Removed the authentication"line "HC2:setBasicAuthentication("login","password")

    Jack,

     

    how did you acces the IUNGO API, is there documentation? Where do I find the OID for the connected devices?

     

    thx

    @twanve, correct, and this works.

    however I would like to extend the code. 

     

    Iungo supports Zwave powerplugs with metering and once connected to the gateway theorie values should also be retrievable from the API. To do that you need the unique OID for that device.

     

    therefore my question was how you could use the api to retrieve the OID's

     

    thx for the reaction though.
