In Norway there are price brackets for power usage. Basically if I spend more than 5 kWh within one clock hour(measured from 8-9 for instance) my power bill will be in a higher bracket costing me 15 Euro more for that month. It’s usually not a problem because I set my electric cars to charge slowly. However, if I run the dish washer or make food at the same time I will go over the 5 kWh within that hour. I have an AMS reader that gives me the live readings in Homey of my usage(using MQTT): 1. Live usage in kW 2. Live usage this clock hour in kWh 3. Live usage this day in kWh Does anyone have any tips how I can set up an alert here? For instance, if I’m at XX:30 and have used 2.5 kWh or more that hour I should get an alert. In the future I’m gonna invest in a smart charger that can follow a similar flow, but for now the output should be an alert. ---

I think you can use the app “Power By The Hour” and look at the tag “kWh this hour” ---

I think this app is especially created for your usecase and the Norwegian pricing system: > [@\[APP\]\[Pro\] Piggy Bank](https://community.homey.app/t/app-pro-piggy-bank/66677): > > This topic is about the Piggy Bank app. The main purpose of this app is to make sure the power usage for every hour is within the targeted power tariff in Norway (now also Belgium - if someone can confirm I did it right). New features are being added continuously.

For notifications you can use my app [POTH](https://homey.app/en-no/app/no.kjeet90.powerofthehour/Power-of-the-hour/), but you need to setup flows for reducing consumption yourself. For a more out of the box solution, as suggested by others, you can use Piggy Bank
