Make your energy purchases greener and cut costs with Arska!
This cloud-free application optimizes energy consumption and battery charging through demand-side flexibility—maximizing the use of self-produced solar energy and shifting purchases to cheaper, lower-carbon-intensive hours.
Arska helps you manage your energy efficiently by controlling loads based on real-time consumption and production data, electricity prices, and solar forecasts. It runs on various ESP32 microcontroller devices and supports:
- On-board GPIO relays
- Shelly (Gen1 & Gen2) and Tasmota Wi-Fi relays
- Fronius GEN24 hybrid inverter charging states
- 15-minute Market Time Unit (MTU) support (Version 1.3)
Arska can manage multiple electric switches, including those connected to water heaters, heat pumps, and other appliances. It controls devices with channel rules using various data sources:
- Day-ahead electricity price per period (1-hour/15-minute intervals) from EntsoE (covering 25 European countries 🇦🇹 🇧🇪 🇧🇬 🇭🇷 🇨🇿 🇩🇪 🇩🇰 🇪🇪 🇫🇮 🇫🇷 🇬🇷 🇭🇺 🇮🇪 🇮🇹 🇱🇻 🇱🇹 🇳🇱 🇳🇴 🇵🇱 🇵🇹 🇷🇴 🇸🇪 🇷🇸 🇸🇰 🇸🇮 🇪🇸 🇨🇭).
Elering provides backup price data for Estonia, Finland, Lithuania, and Latvia. - Grid energy metering (Supports HAN P1 port meters and Shelly 3 EM) – Read more.
