YouLess LS110 Energy Monitor

[Rutger]

A new product from the Dutch market is the YouLess(.nl).
Not quite expensive because of the missing display instead of other products (mostly of the time on a non interesting frequency).
For a price of € 79,- you will receive the sensor (for both analog and slim-meters) and a usb and network cable.
I think the advantage is that the data update is every 60 seconds. Some other products have an update each 30 minutes.
I like to see 'realtime' data.

At this moment there is a desktop widget available and an ios app. Android will be soon available according the website.
They also working on a API, so a data interface to Homeseer should also be possible in the future.

Ordered!

[Rutger]

Me to. I'm also very curious about the usb data connection. In some way this should be added to Homeseer.


@20-02, 22:20 hrs: Sunday afternoon 1 item ordered. Monday 22:10 hrs track&trace number confirmed.

What I've found until today about receiving the data stream:

Please note that this device can't record the amount of energy that you deliver back when using solar panels. (terugleveren)

My comments:

It seems that the USB connection is only in use as a power supply.
You need a cabled UTP connection.
It seems this device will have only one optical sensor to read out the disc or flashing led of the electricity meter. (it is not listed in the part list)
Be aware not all meters with a disc can be handled by an optical sensor depending on the design of the sensor and adjustments.

Not clear and i assume it is not possible to collect data on gas consumption or P1 port.

So it is an in between solution , meters with P1 will be the future.

Had contact with the supplier, they are planning an firmware update or another device for gas monitoring.

This morning the YouLess was delivered finally.
It was send in a very small box which could be put thru the mailbox.

The youLess itself, a long usb cable with EU plug and a short utp cable is delivered. Also a simple but colorful 1 page manual for the basis steps.

At this moment I've an analog powermeter, and to get best input level (read: the highest light intensity for the sensor), I've to spend almost an half hour (for me 29 minutes too long..) to get it right.
What is the right input value? between 6 and 80% according the manual, in my case around 70% so I'm satisfied at this moment.
The input value drops around 40% when the little black stripe comes around because this color isn't reflective. This pulse is also visible in the realtime online config with a small black dot.

Now I've to check the YouLess counter with the counter of the analog powermeter the next days.

The get data from it, it's indeed via the UTP connection.

How can it measure actual usage?

I'm curious if you can get the data into homeseer.

[Rutger]

Actual usage? You have to add the quantity of pulses for each kWh. On your powermeter there is a code visible like C=375.
So 375 pulses for each kWh. In some way you can calculate the actual usage in Watt.

I'm also curious about the get the data in Homeseer. On the YouLess website you can find also an Excel import tool. Maybe I can use the macro for some way to get the right info, I'ven't tried it yet.

[freakstar]

My actual usage is a bit high, 4500 Watt Compared with my Plugwise i don't believe this, but the configuration looks ok. Strange.

[edit]Ah, 10000 pulses per kW.

Will look further at it tomorrow, but first impression is nice and simple.

Input from my digital (LED) meter varies from 0 to 99% by each pulse.

How can it measure actual usage?

I'm curious if you can get the data into homeseer.

I use a simple script to get it into homeseer.




Imports System.Net

Sub Main(parm as object)
Dim strUrl As String = "http://192.168.1.230/a?f="
Dim devIdCurrent As String = "A8"
   Dim devIdTotal As String = "A9"

Dim request As WebRequest = WebRequest.Create(strUrl)
Dim response As WebResponse = request.GetResponse()
Dim data as String = new System.IO.StreamReader(response.GetResponseStream()).ReadToEnd()

Dim s1 As Integer
Dim e1 As Integer
   Dim pwr As Integer

s1 = data.IndexOf("pwr") + 5
e1 = data.IndexOf(",", s1)

pwr = Convert.ToInt32(data.SubString(s1,e1 - s1))

hs.SetDeviceValue(devIdCurrent, pwr)
hs.setdevicestring(devIdCurrent, pwr.ToString() & "W")

s1 = data.IndexOf("cnt") + 6

pwr = Convert.ToInt32(data.SubString(s1,7).Replace(",",""))

hs.SetDeviceValue(devIdTotal , pwr)
hs.setdevicestring(devIdTotal , data.SubString(s1,7).Replace(",","") & "W")
End Sub

Your script works perfectly!!

[Rutger]

Hi Yellowbird,

Thnx for your script.
My counter have 3 digits behind the komma.
The youless counter is on 29661,544 kWh.
In Homeseer I see the value 296615. Your script have the komma 1 place too far to the right?
Do you have the same experience?

[freakstar]

Can you explaine more about the script? How do I implement it?
