You will be provided with a reference and some statements. Please determine whether each statement is 'supported', 'unsupported', or 'unknown' with respect to the reference. Please note:
First, assess whether the reference contains any valid content. If the reference contains no valid information, such as a 'page not found' message, then all statements should be considered 'unknown'.
If the reference is valid, for a given statement: if the facts or data it contains can be found entirely or partially within the reference, it is considered 'supported' (data accepts rounding); if all facts and data in the statement cannot be found in the reference, it is considered 'unsupported'.

You should return the result in a JSON list format, where each item in the list contains the statement's index and the judgment result, for example:
[
    {
        "idx": 1,
        "result": "supported"
    },
    {
        "idx": 2,
        "result": "unsupported"
    }
]

1. Residential EV adoption adds substantial, flexible load and storage capacity to the smart home ecosystem, making coordinated charging and potential vehicle‑to‑home (V2H) or vehicle‑to‑grid (V2G) interactions a key product trend. Research on AI‑assisted demand response and load balancing shows that smart EV charging networks can reduce peak loads by roughly 10–15%, improving grid resilience and efficiency. Commercial analyses highlight dynamic load balancing (DLB) systems that integrate solar generation, BESS, and bidirectional chargers, using predictive algorithms and utility signals to schedule charging and discharging.
2. Residential EV and DER controllers that combine solar inverters, battery systems, and EV chargers into unified smart home energy platforms for load balancing, resilience, and arbitrage.
