What is the current electricity price in Austria?

The current electricity price in the aWATTar HOURLY tariff is 8.9 ct/kWh (as of 15.05.26, 10:42). Prices change hourly based on the spot market.

Which devices are supported?

Currently EnergyOptimizer supports all Tuya-compatible smart plugs (e.g., WiFi sockets from Action, MediaMarkt). Shelly devices coming in Q2 2026. For heat pumps and wallboxes, direct SG-Ready integrations are in progress.

Do I need a dynamic electricity tariff?

Yes, optimization works with all EPEX-based spot tariffs – in Austria e.g. aWATTar, smartENERGY, Verbund, Wien Energie and 10+ more. In Germany, Tibber, Ostrom, 1Komma5° and others work. If you don't have one yet, I'll help you switch.

How much can I really save?

Savings depend on your consumption and electricity tariff. Typically 20–40% reduction in costs for devices like boilers or heat pumps. With my clients in Austria, savings regularly land between 20 and 38%. Use my calculator for a personalized estimate.

Where do the electricity prices come from?

We fetch hourly exchange prices directly from EPEX SPOT – the same data source used by all Austrian and German spot tariff providers. Prices are published 24 hours in advance, allowing us to optimize predictively.

Absolutely. All data is TLS-encrypted and stored on EU servers in Germany. EnergyOptimizer is GDPR compliant – data is never shared with third parties. Werner.Solutions is an Austrian company based in Graz.

What happens during internet outage?

On connection loss, the system switches to fallback mode: your devices are controlled via a timer schedule (default: 10 PM - 6 AM). Once connection is restored, real-time optimization continues automatically.

What's the minimum boiler size?

For meaningful optimization, I recommend at least 50 liters of storage capacity. From 80 liters, savings become noticeable as more energy can be shifted to cheap hours.
