If you are using the dynamic price feature in Homey Energy, you may be interested in an app I created that takes that information and use it to control energy usage.
Specifically it can shift loads based on cheap or expensive hours, and it can distribute a daily kWh budget based on price.
In addition, it can also do things like modes (Home/away) and limit concurrent consumption.
If this is interesting to you, have a look at PELS | Homey
Hope this can be of use to you.
Note: PELS is heavily inspired by Piggy Bank (Sparegris). That app worked well for me for a long time, but it has unfortunately not received any updates for some time, and I wanted something a bit more tailored to my own needs.
