With the flexibility context, we aim to describe the system in which the flexible assets operate, such as its physical and contractual limitations. +For multi-commodity scheduling problems, the flex-context can be defined separately per commodity (e.g. electricity and gas), using the ``commodities`` field. Fields can have fixed values, but some fields can also point to sensors, so they will always represent the dynamics of the asset's environment (as long as that sensor has current data).

Claessen * fix: skip aggregate computation for unused commodities When a multi-commodity flex_context includes a commodity (e.g., heat) but no devices exist for that commodity, the sum() of an empty list returns integer 0 instead of a pandas Series. This caused AttributeError when calling .round() on the result later in compute(). Fixed by checking if any devices contribute to the commodity before attempting to aggregate. If no devices exist for a commodity, skip creating an aggregate schedule for it. Signed-off-by: F.N. Claessen --------- Signed-off-by: F.N.

Even though both inverters *can* do both, the optimiser specialises each for the operation it is most efficient at. +- **Shared storage** (bottom panel) shows the *single* ``state-of-charge`` sensor that both inverters feed. It starts at the 20 kWh ``soc-at-start``, climbs while inverter 2 charges, reaches and briefly holds the 189 kWh target, and then falls as inverter 1 discharges — bottoming out at the 10 kWh ``soc-min``.
