Ipad Energy panel

[KristianO 15]

Hi,

 

I use my Ipad to control my HC2 with a wall mount. With this I can control the center and monitor the energy consumption.

 

Im now planning to buy a 3-phase clamp or a NorthQ power reader to get the total energy of the house to be shown in the ipad energy panel.

 

But how do I exclude all my existing single devices from this total? This device should represent the total and all my other devices a sub-total out of this.

 

I want the ipad to show the total but keep the possibility if selecting individual devices.

We're having that same problem. We have a clamp showing the total energy consumed in the house, and then we have other devices reporting its own consumption, so Fibaro adds all the consumptions and tell me that the consumption is higher than the real one.

 

Any way to fix this?

@Fibaro support?

[Guest Tonyb_AU]

I am using a Rainforest energy meter to connect directly to my meter, however this is not supported by Fibaro, so I have a virtual device that retrieves the values from the Rainforest (or any other such meter) and then performs a calculation, that basically is whole_house - (all fibaro energy devices) = result. And then I push this result into a spare channel (ID = 131 below) on a Fibaro Double Switch, therefore getting the energy figure into Fibaro.

 

        -- get current power comsumption of all energy reporting devices    
        local devices = fibaro:getDevicesId({interfaces ={"energy"}})
        local device_watts = 0
        for k,v in pairs(devices) 
        do
              -- exclude the rest of house energy device (131)
              if (v ~= 131) then
                local this_meter = fibaro:getValue(v, "power")
                  fibaro:debug("id = " .. v .. " ,meter usage = " .. this_meter)
                  device_watts = device_watts + this_meter
               end
          end
        fibaro:debug("total device watts = " .. device_watts )

        local true_meter_watts = meter_watts - device_watts

 

        HC2 = Net.FHttp("127.0.0.1", 11111)
        jtable = "{\"properties\":{\"power\":" .. true_meter_watts .. "}}"
        response, status, errorCode = HC2:PUT("/api/devices/131",jtable)
        fibaro:debug("update the _KW_METER device")

  

That way I get the true total house energy shown in Fibaro

@Tonyb_AU Thanks a lot. We'll give a look at that, but I think @Fibaro should be able to give us a better solution. Something like a checkbox where you say "This device measures global energy consumption for the room" or "This device measures global energy consumption for the house".

[KristianO 15]

So I got a Fibaro FGS device with master id as 381 (hidden). I then slaves with id 382 (used) and additional slaves 383-384 (hidden).

 

- Can I then use id e.g. 383 or 384?

- Do you assign this id to room "House" only for this purpose and keep it hidden? Since the switch makes no sense.

 

[Guest Tonyb_AU]

@KristianO As long as 383 or 384 is a switch object, then it can be used. I have just assigned it the name '_REST OF HOUSE' so that it shows up in the Energy panel, you must however leave it switched on, otherwise it won't report the consumption.

 

This is how my switch device looks.

Thanks!

 

- So you use any energy meter and get the data from it using an ordinary API and store the data in a virtual device on a regular basis.

- You then use the same virtual device and push the difference between total and sum of all device to a channel 2 of the switch. 

- A scheduled scene updates the VD "button" with new values every "15 minutes"

- The channel 2 is assigned to a "Total House" - Room.

- The channel 2 is set to always "On" but hidden in the system.

 

All true?

Hi @KristianO,

 

Did you checked this:

It is prepared for use with Aeon Labs HEM but it can read consumption from any device with little change in code. I use it with my HEM and it works nice.

Hi @KristianO

 

- So you use any energy meter and get the data from it using an ordinary API and store the data in a virtual device on a regular basis. - YES

- You then use the same virtual device and push the difference between total and sum of all device to a channel 2 of the switch.  - YES

- A scheduled scene updates the VD "button" with new values every "15 minutes" - ALMOST, the new values are updated every 30 seconds as part of the virtual device main loop

- The channel 2 is assigned to a "Total House" - Room. - YES

- The channel 2 is set to always "On" but hidden in the system. - YES Always on, but not hidden (not sure if it still displays in the energy panel if hidden, have not tried this)

don't know if this helps.. but with HC2 FW 4.134 i use an Qubino Smart Meter (

Please login or register to see this link.

) to measure the power usage of my aircon.

 

After including the smart meter i added it into an empty room (Klimaanlage = aircon)

 

in enegry metering i now can choose only this device to see the consumption.

assuming, that you would like to know the house's total consumption this could be a way..

 

i'm now looking for a way to eport the daily or weekly stats...
