Yup, I’ve tried it out. You’re right, the current Home Assistant plugin doesn’t support the kind of trigger events that I’ve mentioned, but there’s no reason why it couldn’t. The functionality required is there in the underlying Python client (GitHub - scottbonline/sense: Sense Energy Monitor API), but doesn’t seem to be working at the moment.
Anyway, I was just hoping to illustrate what could be possible if this data was made more accessible.
