Note:

I am in no way associated with PostFossil, the Youless' manufacturer, just an enthusiastic user of the device.

 

 

The Youless LS120 Enegy Monitor is a tiny piece of hardware to collect logging information from a "slimme meter" (smart meter) through its P1 port.
It connects to your local ethernet network, and allows you to access the collected data from a cell phone (using Wifi) or computer.

Once connected, you can easily get a summary by browsing to http://youless/

The device comes with some standard apps, and spreadsheets with macros to collect the data over a longer period than the device's 1 year limt; however, what I really like about it, is the ability to get at the raw data and present it any way I want.

The Youless "API" is well documented by TD-er.

• A very basic summary can be displayed using wget:

• Youless.exe is my first attempt at reading basic Youless info with C#.
  You may want to add S0-related values (for additional solar panels kWh meter, if available) and/or translate the output descriptions.
• Youless.bat will give you identical results:
