Allow defining Circuits, which consist of two (or more) Loadpoints

[bodomenke]

As-Is Situation
I have two easee wallboxes (each 11kW) on the same electrical circuit, which is limited to 11kW. Definition in easee cloud is as follows:

• One circuit with 11kW (actually limited to 15A for each phase)
• Two wallboxes with 11kW (actually limited to 15A for each phase) on the previous defined circuit

Loadbalancing between the two wallboxes and ensuring that both wallboxes combined do not consume more than 15A for each phase is being done by easee.

This setup is working pretty well with evcc: Even if both loadpoints have defined a max current of 16A per phase and two cars are charging, easee is taking care that current is not exceeding 15A per phase on the circuit.

Problem
If I define plans for both loadpoints, which are overlapping, then evcc doesn’t consider that, since it doesn’t know about the circuit limit. evcc assumes, that both loadpoints are capable to consume the max current of 16A for each phase. For this reason the plans, which evcc creates for hitting the departure time fail, since the loadpoints will only receive 50% of the current (which is balanced by easee).

Solution

• Define a circuit entity in evcc, which has a „Max. Current“ setting
• Allow to attach multiple loadpoints to one (the same) circuit
• Consider „Max. Current“ setting of the circuit, when (overlapping) plans are being defined for the loadpoints

Alternatives / Workaround
A manual workaround is to limit temporarily the „Max. Current“ setting of the loadpoints to 7A for each loadpoint. This is not ideal.
