Averaging

Hello,

I'm a happy flukso user. But there are some things I think they would be nice.
Is there an option to get not the average from the gas and water sensor, but just the input at that moment?
I used the whole day around 0.05 liter water and gas. And when I flush the water closet, I used somethimes 1 liter, otherthimes 2, 3 or 5 liter. Thats not true!
When I flushed the toilet, I used always 5,5 liters. So it should be somethimes 5 liter, otherthimes 6 liters. Why didn't I get these values out of the graphics? Is there any option to measure that there is NO water and gas consumption when there is no water and gas consumption?

I hope you'll understand what I mean. I have searched the site for an answer, but I couldn't find.

What's the accuracy of your gas and water meters (liter/pulse)

hanskraayeveld's picture

Gas 10 liter 1 pulse. Water 1 liter 1 pulse

I found the answer somewhere on the forum here...

Hi Amedee,

You will indeed have a non-zero flat line due to pulses being counted on the device in the 5min interval prior to the self-inflicted black-out. These pulses were never reported to the Flukso server. In the first reporting after power-on, the server will notice that the counter has increased since the last reporting and will evenly distribute the energy over the time interval.

Cheers,
-Bart.

Is there an option to change this?

Is there nobody from the company of flukso who think:
Maybe we could make a simple manual for flukso?
Telling the people who knows nothing some information....

E.G:

Current clamps are not the right way to monitor to measure solar panels.
The last pulses of the pulsmeter are not being monitored, and they where flattened out to the time there is new moving of the pulsmeter.

Just some little things... It helps people who starts up with metering.

To quote the About page: "Flukso is an open source web-based community metering application"; thus, as this is an open community, feel free to start a "how to" and record your experiences, like others did before you, like I also did; so, don't moan, get active! - Shu Ha Ri

Yeah it would be nice! But i'm sorry. I don't have any experiences on programming and these stuff. I'm just a user...

But there are so many things to make better.

In dash, for example, the electricity isnt good. watt and watt hour are changed.

By month, my watt hour of my solar panels are 504 and my watt is 21 a day.
I think thats not good. They have to change. The sum of all is never time limited!
The average is time limited!
The watt/hour is 21 and the watt is 504.

And i would like to set in gas and water, liter as default...
Not possible.

But... Flukso is a good idea. If it was mine, i should be proud, but i took some time in it to make it better/easier.

And watt cumulative, not watthour cumulative

gebhardm's picture

I must admit, I do not get your request?! You seem to heavily mix up physical terms and units...
What would you expect "watt cumulative" [power cumulative] to be?!
An example:

A hair dryer has a wattage (as unit of power (!)) of 2000W; when I dry my hair for 10 minutes I consume 2000W for 10min (=1/6 hour) what equals to an energy (!) consumption of 333,333 Wh - the [Wh] equal the integral over time 0 S 10min 2000[W] dt = 2000 [W] * 1/6 [h]. This is "the same" (read: the same energy consumption) as drying my hair with a hair dryer of wattage 333,333W for one hour or one with 4000W for 5min (won't try the latter).

Another example

My photovoltaic installation has a peak wattage (peak power) of 3.680Wp, so it can in the maximum produce a peak of 3,68 kW - physically there is no more wattage deliverable possible; sunlight is shining differently along the day, thus the actual power (!) at a given time will vary, starting at 20W around 10:00AM, rising to peak at noon, falling to switch-off during the afternoon. On a sunny day I harvest around 25kWh of energy (!)or an "average" of 25[kWh]/24[h] = 1042[Wh]/[h] = 1042 "[W]" (the average "counts" also during night, which, of course, is not possible; thus "eliminating" the [h] is actually semantically not correct )

Then there are devices that actually just report (!) the (power or gas or water) consumption without a statement on how long it took to achieve it (the Fluksometer from a pulse just recognizes that at a certain time a certain amount (=sum) of consumption (or production) was reached; for an approximation from the time since the last pulse you may "suggest" what an equivalent (power) might have been.
This adheres to the peak load issue I described in Peak load part 1 and Peak load part 2
So, now, what is your expectation or question?

hanskraayeveld's picture

Gebhardm, could you look in dash by electricity and the interval MONTH.

hanskraayeveld's picture

And look at your watt and watthour consumption

hanskraayeveld's picture

Maybe I'm wrong!?
And watthour cumulative, is watt cumulative? Cause the total is not in an hour? Or am I abused???

gebhardm's picture

I still don't get what your issue is; looking at your monthly dash everything seems rather plausible: You are online since Nov.22; in that time period since, you have an average consumption of around 8kWh per day; this sums up over the corresponding period to 102kWh (not a whole 30 days!); this means you have an average consumer that runs at around 300W hour by hour... PV is rather low, but this is the year's time and I don't know how large your installation is...
Corresponding to my dash (three phase setup): Over the last 30 (!) days I consumed 110kWh (cumulative), have a PV provisioning of 78kWh - in average I have a consumption of around 4 to 5kWh a day, meaning there runs an equivalent consumer in average at around 190W... (all values rounded)
So, you should hunt for the device that brings up your consumption (and get someone who provides you some physical background as you really seem to mess up some concepts)

Please look at the photo's I attached. Photo's says more than 1000 words. I have compaired it with your results.

On photo 1, on 5 dec, I have 5,5 kw HOUR! I know I spend a lot of energy.... But this much? Thats aroud 125 kW/day...

On photo 2, on 5 dec, I have 232 watt... What? 232 a day?? Thats not so much.

On photo 3, On 5 dec, I have more than 100kW. yeah 100kW, but not 100kwHOUR!
I think my electric cables couldn't have this much.

You can look at your results too...
Maybe you have another dash...

gebhardm's picture

I give up. On Dec 5 (the whole day's consumption) in total you spent 5.5 kWh energy (picture 1 - unit is Wh) - that's a rather normal value for a normal household (as written, I have a three-phase installation, so you have to add the values of L1 to L3).
This means an equivalent of a device taking 230W per hour running for 24h - not too bad as well (picture 2 - day value again, unit now is W as this is an equivalent respective average)...
In total, over your period of using the FLM you used 104kWh (what your utility charges on the energy bill- unit is Wh) - as written, this is nothing unusual.
Please, please, try to get an understanding on the difference between power [W] and energy [Wh]...

By the way, I optimize electricity consumption for quite some time now; so the low values are a stimulus, not a reference; there are other Fluksonians with even lower energy consumption - that is what this is all about...

hanskraayeveld's picture

Damn, your right! I'm so sorry...

gebhardm's picture

You are welcome.

Daily usage: Water: 1 liter/hour = 24 liter
Gas: 1 liter/hour= 24 liter
Electricity: 1watt= 24 watthour
Is this right so?
If it is:
Strange! Who is this guy who solved this :)

gebhardm's picture

Sorry to correct you, but no. It is actually: 1 watt "for a time span of" (or "multiplied by") 24 hours equals 24 watthours - E = P * t - it is a time integral; the same applies for gas and water consumption, when these are given as a "time difference" (thus, liters per hour); don't neglect the period of time for which you make the "equality"...

hanskraayeveld's picture

I understand... Thanks a lot!

Fun discussion! I'm glad everything is clear now.

But still, I see an interesting feature request, (which has been proposed before):
>> And i would like to set in gas and water, liter as default... Not possible.
=> Feature request: Construct the graphs using correct and easier, human-interpretable units at the y-axis, possibly with a preferred default units.

I'll start a topic in the dev section.
