PRISME: energy management: spot price,peak protection,EVcharging,photovoltaics [beta] - Paulianer - 16.09.2026
Hello! Here is PRISME, an energy management app for LogicMachine.
It reads the hourly spot price, the weather forecast and your own meters, and
decides from them when heating, hot water and the EV charger should run:
1.) Load control on price, lowers setpoints or sheds on expensive hours,
boosts on cheap ones
2.) Peak protection, sheds load before the hourly average crosses your
threshold, and keeps you off the next grid tariff step
3.) EV charging, picks the cheapest hours before your deadline, backs off
when the house draws hard, can prefer hours with expected sun
4.) Solar model, learns your installation's clear-sky curve and adjusts for
season and cloud
5.) Reports and an event log, every decision with its reason and the change
it made, all exportable to a spreadsheet
Price zones for Norway, Sweden, Denmark and Finland. More price zones can be added, just ask
Interface in English and Norwegian.
**This is a beta.** It's been testet in one house, mine. Zaptec, Schneider EVlink Pro
AC and the Victron integration have never been connected to real hardware;
Easee is well tested. Please read the attached README before pointing it at
anything you care about. It covers the requirements, the limitations and what
leaves your house.
You can see the whole app before wiring up a single address:
**Help → Getting started → Show example data** fills every page with a
fictional house, entirely in your browser.
Please use this thread for questions, suggestions or wishes. I would especially like
to hear from anyone on a different grid tariff, and from Zaptec, EVlink or
Victron owners as those are the parts I cannot test myself. Any feedback is
more than welcome.
