That's from Telefonica. It could be related to cable TV.

Looks like these URLs are not permalinks. Yesterday, this URL was showing something with two electrical pylon icons and rather large numbers like 9,000 kWh. Today, it's changed to some TV thing like you said.

A personal class electric counter panel ?

Huvudmeny: Main Menu

Frysrum: Freezer

Maskinrum: Engine

Fryshus: Cold Storage

"Rum" is room, so maskinrum = engine room, etc.
