Wattlane

Open Wattlane, select a discovered Shelly, Tasmota, Kasa, or myStrom plug, and the cost dial shows that appliance’s running cost based on live power readings and your tariff. Turn a virtual plug on or off in the built-in demo home to update the same dial instantly, so you can try every screen without any hardware. The app reads smart plugs only over your own Wi-Fi network, using Bonjour browsing, a one-subnet probe, or manual IP entry. No vendor cloud or account is required: devices are discovered and controlled locally, while historical cost data is logged on the device for review in the history view. Planning compares your appliance schedule with public data: day-ahead electricity prices from Energy-Charts, UK grid carbon intensity from the Carbon Intensity API, and a solar forecast from Open-Meteo based on a location you enter. The planner, tariffs, meters, and calculator use this data to align heavy loads with cheaper or greener hours. All features are available for free from the first launch. No account is required. Shelly, Tasmota, TP-Link, and myStrom names are mentioned only to describe compatibility; Wattlane is not affiliated with them.
