EcoWatch Johanna - Ø 40 cm

The electricity price clock you can read from across the room. EcoWatch Johanna is 40 cm in diameter with 72 LEDs, built for open-plan living rooms, workshops, schools and offices. The white dial and black frame make it a statement piece, and the colour ring is visible from the sofa.

How Johanna shows the price. Six LEDs per hour give quarter-hour resolution across a 12-hour dial: you see the current hour and the next eleven, with every price change visible as a shift in colour along the ring. Johanna has no inner ring; everything goes into one large, clear display.

Same brain as Julia. Five colour modes, 18 price areas, Shelly smart-plug control, MQTT and Home Assistant, automatic updates, 6 settings-page languages.

Where Johanna fits. Above the sofa, in the hallway of a villa with an EV charger, in a staff room, or anywhere a 25 cm clock would disappear.

Works in 18 price areas. Sweden SE1–SE4, Finland, Norway NO1–NO5, Denmark DK1–DK2, Germany, Netherlands, Estonia, Latvia, Lithuania and France, with prices in SEK, EUR, NOK or DKK. The settings page is available in Swedish, Finnish, Norwegian, Danish, German and English.
