I really like the idea of building an Advanced Flow instead of relying on an app, it’s a great way to learn more about how flows work and gives you full control!

### Here’s a step-by-step suggestion:

1. **Install the [Strømregning app](https://homey.app/no-no/app/no.almli.utilitycost/Str%25C3%25B8mregning/)**  
This app gives you the flow cards needed and tracks your energy usage over the last hour.  
You need to feed it data from a smart power meter or a device that measures consumption, as described [here](https://community.homey.app/t/fersk-men-frustrert-ny-bruker-sette-opp-styring-ut-fra-pris/139448).
2. **Set up the devices you want to control**  
Start with the **lowest-priority device** and assign it to turn off first at the lowest kWh threshold. Then add the next device in order of importance, with increasing kWh values. The **highest-priority device** should be the last to turn off, at the highest threshold (closest to your limit).
3. **Choose your kWh limits and reactivation rules**  
You can customize when each device turns off/on and how soon they should be reactivated if conditions allow.
4. **Add a confirmation step for critical devices**  
For high-priority devices (like an EV charger), you can add a **push notification** with a Yes/No option to confirm before turning it off. Or skip the notification and automate it fully.
5. **Set reactivation thresholds**  
Define a lower kWh value at which your devices — especially high-priority ones — are allowed to turn back on. Make sure to turn on the lower-priority ones also if they were shut down and have not turn back on yet.
6. **Optional: Add or remove notifications**  
Customize your flow with alerts depending on your preferences.

I don’t have an EV charger connected, so I’ve just used a basic card to visualize the concept.  
Be sure to test the flow thoroughly before depending on it fully.  
Adjust as needed to fit your setup and preferences 😉
