The [YouLess LS110] is a kWh meter to ethernet bridge, which detects the turns of the rotor disc or LED-pulses of an electricity meter. These turns or flashes are proportional to a certain amount of electric energy used. This information is being logged and can be sent to a website like [Bidgely]. It can also be queried from a networked device on the local network (via http) to get real-time power consumption.

Page Layout

The page layout is split in two parts (left and right) and for some queries, there is a JSON option to retrieve the data.

In the table below:

  • the URLs should be prefixed with "http://<IP-address>"
  • The items marked with a "*" do not apply to the LS110.
  • The items marked with a "**" are introduced in later LS120 firmware versions.
  • URL can be combined from multiple cells in the table below. For example: http://<IP Youless>/V?h=1?f=j
  • http://youless/M?c=123456 will set the S0 counter to 123,456 kWh. The value given is in Wh, not kWh.

RAW P1 Telegram

The RAW P1 telegram is present, using this URL (replace IP-address):

 http://192.168.1.14/V?p=1

If the telegram message appears to be too long (may differ per meter), the 2nd part of it can be accessed via:

 http://192.168.1.14/V?p=2

Actual power can be found at: 2x.7.0, 4x.7.0 and 6x.7.0

This was only mentioned by [YouLess on Gathering of Tweakers] as a debug function for support.



Reboot Youless

You can remotely reboot the Youless, using this URL (replace IP-address):

 http://192.168.1.14/S?rb=

It uses the special "/S" page, which contains several undocumented parameters.

Device Info

The url "/d" will always output JSON data:

 {"model":"LS120","mac":"72:b8:ad:14:00:04"}

Basic status info

The url "/a" has two output formats:

  • Plain text ("/a")
  • JSON format ("/a?f=j")

Plain text

Page "a" (e.g. http://192.168.1.14/a ) will return some data in plain text:

 4456,980 kWh
 457 Watt
 0%
 OK (13)

JSON

The URL "/a?f=j" will output something like this:

 {"cnt":"4457,005","pwr":453,"lvl":0,"dev":"","det":"","con":"OK","sts":"(52)","raw":0}
  • cnt: counter in kWh
  • pwr: Pwer consumption in Watt
  • lvl: moving average level (intensity of reflected light on analog meters)
  • dev: deviation of reflection
  • con: connection status
  • sts: Time until next status update with online monitoring
  • raw: raw 10-bit light reflection level (without averaging)

Please note that the kWh-data may have one or two leading spaces when the count is below 100 kWh. For example:

 {"cnt":" 22,285","pwr":764,"lvl":0,"dev":"","det":"","con":"OK","sts":"(06)","raw":0}

Also other small values may have one or more leading zeroes.

Values can be zero (" 0") or even be marked as not active ("*"). For example not active:

 {"un":"Watt","tm":"2017-08-17T13:24:00","dt":60,
  "val":["*","*","*","*","*","*","*","*","*","*",
         "*","*","*","*","*","*","*","*","*","*",
         "*","*","*","*","*","*","*","*","*","*",null]}

No production/consumption:

 {"un":"Watt","tm":"2017-08-17T22:27:00","dt":60,
  "val":[" 0"," 0"," 0"," 0"," 0"," 0"," 0"," 0"," 0"," 0",
         " 0"," 0"," 0"," 0"," 0"," 0"," 0"," 0"," 0"," 0",
         " 0"," 0"," 0"," 0"," 0"," 0"," 0"," 0"," 0"," 0",null]}

Note the "null" terminated array to allow variable number of elements.

Uploaded Values

The url "/e" will output the same values as being used to upload and are thus firmware dependant. These were probably used for debugging, but can also be used for other applications like connecting to Domoticz or OpenHab.

Enelogic (default) firmware

Output is always in JSON format:

 [{"tm":1489333828,"net": 2375.216,"pwr": 1402,"p1": 2523.531,"p2": 2087.307,"n1": 686.432,"n2": 1549.190,"gas": 2611.792}]
  • "tm": unix-time-format (1489333828 => Sun, 12 Mar 2017 15:50:28 GMT)
  • "net": Netto counter, as displayed in the web-interface of the LS-120. It seems equal to: p1 + p2 - n1 - n2 Perhaps also includes some user set offset.
  • "pwr": Actual power use in Watt (can be negative)
  • "p1": P1 consumption counter (low tariff)
  • "p2": P2 consumption counter (high tariff)
  • "n1": N1 production counter (low tariff)
  • "n2": N2 production counter (high tariff)
  • "Gas": counter gas-meter (in m^3)

New values (since 1.4 version firmware)

  • ts0: S0: Unix timestamp of the last S0 measurement.
  • cs0: S0: kWh counter of S0 input
  • ps0: S0: Computed power
  • gts: Last timestamp created by the 'smart meter'. "1711032100" = 2017/11/03 21:00 (yyMMddhhmm) Can be used to see if P1 communication fails.

PV output firmware

Th non JSON format output is in the format described on the PVoutput site:

 d=20170817&t=22:56&v1=0&v2=0&c1=1&v3=1935267&v4=570
  • d: Date YYYMMDD
  • t: Time HH:MM
  • v1: S0 input as bruto production input (Energy Generated in Watt hours)
  • v2: ????? (Power Generated in Watt)
  • v3: Value displayed as "Meterstand" in Wh. (Energy Consumed in Watt hours)
  • v4: Actual power (Power Consumed in Watt)
  • c1: 1= lifetime values (Cumulative Flag)

N.B. only updated values will be shown. For example with the P1 disconnected and S0 connected:

 d=20170819&t=10:19&v1=13148&v2=2400&c1=1
Cumulative Flag

Cumulative Energy Set the cumulative flag c1 to 1 when you wish to pass lifetime energy values for v1 instead of today's energy value. The first add status for any given date will be used as the starting energy value and v1 will be reset to 0.

Historical data

The source of page "R" contains some links to pages with historical data. For example, "V?m=1" will show the kWh values for januari in plain text and "V?m=1&f=j" will display this in JSON format.

 {"un":"kWh",
 "tm":"2012-01-01T00:00:00",
 "dt":86400,
 "val":["  0,000","  7,200","  8,000","  8,200","  6,600","  7,900","  8,600"," 10,600",
        "  6,200","  7,000","  8,200","  5,100","  8,900","  5,900","  7,300","  7,400",
        "  6,900"," 12,200","  6,700","  8,500","  7,100","  7,700","  1,300","  8,500",
        "  5,500","  7,700","  7,500"," 10,200","  8,100","  6,300","  4,100",null]}

This sample (output without newlines) contains the following information:

  • unit: kWh
  • start time: 2012-01-01T00:00:00
  • delta time (time between samples): 86400 seconds (1 day)
  • an array with values for each (recorded) day (array is null-terminated)

Resolution of historical data

Due to memory limitations, the historical data is stored with a larger interval when it's further back in time.

  • Power is in Watt, except for the day-resolution, which uses kWh.
  • Gas is in Liter, except for the day-resolution, which is in m^3.
Resolution Power LS-110 Power LS-120 Gas LS-120 S0 LS-120 **
Range URL Range URL Range URL Range URL
Minute 1 hour /V?h=1..2 10 hours /V?h=1..20 None 10 hours /Z?h=1..2
10 mins 1 day /V?w=1..3 10 days /V?w=1..30 10 days /W?w=1..30 10 days /Z?w=1..30
Hour 7 days /V?d=1..7 70 days /V?d=1..70 70 days /W?d=1..70 70 days /Z?d=1..70
Day 1 year /V?m=1..12 1 year /V?m=1..12 1 year /W?m=1..12 1 year /Z?m=1..12

N.B. each url can be complemented with "&f=j" to get the JSON-version of the data. Note that some values may contain leading spaces.

The LS-120 also has a page for the gas consumption, which is located at page "W". The same applies as for page "V", described above, with exception that there is no page for the last hour. Most gas measurement systems only update the gas counters once per 10 - 30 minutes, so log per minute is of no use. The gas consumption can be viewed in detail up to 10 days (30x 8 hours) back in time. (w = 1 ... w = 30)

(**) The LS-120 firmware version 1.4 also logs the S0 input with the same schema as the Power logs.

Cacti script

For logging purposes like Cacti, a script only needs to output a number on one line. This will just do that:

 #/bin/bash
 wget http://192.168.1.14/a -q -O - |grep kWh|sed s/\ kWh//|sed s/\,/\./|sed s/^\ //

This will output something like this:

 15.971

Windows PowerShell

Suggested by user [Frost_Azimov]

 $data = invoke-RestMethod -Uri $url -Method Get

With $url the Youless url + ' /e' . This will parse the JSON data into a PowerShell object.

e.g. $data | fl (using the Enelogic firmware) will output:

 tm  : 1509739737
 net : 31777,244
 pwr : 1080
 ts0 : 1509738000
 cs0 : 0,000
 ps0 : 0
 p1  : 18728,542
 p2  : 13048,716
 n1  : 0,008
 n2  : 0,006
 gas : 5444,593
 gts : 1711032100

See #Enelogic_.28default.29_firmware for more details.
