Dynamic Electricity Price Control with Shelly Plug and clever-PV
Overview
This use case demonstrates how clever-PV’s dynamic Price Feature connects with Shelly Plug S MTR Gen3 to automate devices based on dynamic electricity prices.
The setup is designed for ultimate simplicity: users pair their Shelly Plug with clever-PV in just a few clicks, and clever-PV takes over all control automatically.
By combining price signals, PV forecasts, and consumption data, clever-PV ensures devices run at the cheapest and most energy-efficient times.
Scope/Deployment:
Households and small businesses in Germany
Compatible with dynamic tariff providers like Tibber, Rabot Energy or enviaM and all epex Spot Tariffs.
Goal:
Automate energy-intensive devices
Maximize cost savings
Minimize user interaction and manual scheduling
Challenges
Highly dynamic pricing: Electricity prices fluctuate every 15 minutes and vary from day to day in dynamic tariff models.
No real-time transparency: Without integrated price signals, manual control is nearly impossible for users.
Cost risk during peak hours: High energy consumption during expensive price periods can significantly increase overall electricity costs.
Solutions / Implementation
Solution:
With clever-PV, users set a price threshold once, and the Shelly Plug is switched automatically based on dynamic price curves.
Because of the direct integration, the entire setup takes just a few clicks. Clever-PV retrieves all data, calculates optimal activation windows, and controls the Shelly Plug without any additional user input.
Key Features:
easy Shelly integration in clever-PV
Automatic control based on real-time electricity prices
Combines PV surplus detection with dynamic tariffs
Remote control and monitoring in clever-PV App
Implementation:
Connect Shelly Plug to clever-PV in a few clicks
Set a simple price threshold or operation time in clever-PV
clever-PV automatically switches devices based on price and PV forecasts

Devices operate only when electricity is cheapest
Improved ROI for households with dynamic pricing
Performance Example (Chart Analysis):
In the chart, the blue bars visualize the forecasted operation times calculated by clever-PV.
The algorithm intelligently avoids high-price periods, ensuring the device only runs when energy prices are low or solar surplus is available.
This automation guarantees maximum cost efficiency without any manual adjustments from the user.
Conclusion
With Shelly Plug S MTR Gen3 and clever-PV, energy-intensive devices are optimized automatically without any technical configuration.
Users enjoy maximum savings and a hands-off experience while clever-PV handles everything in the background.
