Axle Energy VPP

Hi, Does SEM support Axle Energy grid events? Thanks

Hi @blackpatina 👋

Short answer: not today. SEM has no native integration with Axle Energy, and it doesn't consume VPP / flexibility grid-event dispatch signals (i.e. an aggregator remotely telling your battery/EV to charge, discharge or curtail for a grid-balancing event).

What SEM does do is price-responsive optimization on dynamic tariffs — it reacts to import/export prices, not to dispatch commands. Supported price sources are Tibber, Nord Pool, aWATTar, Amber Electric and Octopus Energy, plus a generic price sensor (any HA sensor whose state is the current price). On that basis it does things like cheapest-window night charging, battery export arbitrage on spot tariffs, and pausing daytime grid top-up during expensive hours.

So the practical implication for Axle:

• If Axle exposed its signal to Home Assistant as a price sensor, you could point SEM's generic price entity at it and get price-style behaviour.
• But Axle's actual model is event/dispatch-based (it controls your assets during grid events), which is a different mechanism SEM doesn't currently speak.

I've logged this as a feature request so the maintainer can track interest — see #580. Thanks for raising it! 🙏
