The electricity price clock for the kitchen wall. EcoWatch Julia is the model most people choose: a 25 cm wall clock with an LED ring that shows the electricity price for every quarter of an hour in green, yellow and red. No app, no subscription. Hang it where the family passes, and everyone knows when to run the dishwasher.

How Julia shows the price. Julia comes in two versions. The 12-hour version has 48 LEDs on the outer ring, one for every quarter hour, so you see the current hour and the next eleven in fine detail. The 24-hour version shows the whole day on one dial, with two LEDs per hour, so you can plan tomorrow's charging or laundry as soon as the prices arrive around 13:15. Both versions have a second, inner ring of 24 LEDs that you can use for the tariff hours, for the day's green hours, or for your home's live power use if you add a HomeWizard P1 meter.

Five ways to decide what is cheap. Daily average, average over 1–7 days, your own price limits in SEK or EUR, a fixed number of green hours per day, or average plus a tolerance you set. Negative prices can show as blue, and tariff hours as orange. Colours and brightness are yours to change.

Connect your home. Julia switches Shelly smart plugs and relays by price, so a water heater or EV charger runs on the cheap hours. It also publishes prices over MQTT and appears automatically in Home Assistant.
