australia demand charges

[jeffborg]

Hi,

I've noticed the circuits setting, it would great if this could be settable as I need to limit the total import at some times of day due to our tariff structure.

I'm also using amber which is a dynamic tariff and have solar so it could be possible to have cheap power during this demand period, so would like to allow grid meter to max out around 3000w during the demand period. Normally max is set to 150000w.

At the moment I'm using calc on the meter to add a fixed offset which I can set via mqtt, but this ruins the evcc display by adding fake house consumption which doesn't exist which from above is 12000w

Unless there is some other way to achieve this?

You can try an aux Meter with negative value.
But I guess the value must be recalculated all the time.

I'll have a play with that, for now will just turn off evcc at 3pm and set grid charge price to 0 which disables that via home assistant.

Sorry, thought wrong. aux is only working in pure pv-mode and not together with cheap price.
