Chashmalink answers questions about Israeli household electricity from measured smart-meter data rather than estimates off a bill.
Behind it sits an analysed corpus of more than 20,000 Israeli households across 500+ municipalities, each a full hourly export from Israel Electric Corporation — up to 17,520 meter readings per home. That is what lets these tools answer with a number rather than a rule of thumb.
Ten read-only tools:
• compare_electricity_plans — rank every plan on the Israeli market by what it would save a specific household, per month and per year. Takes a monthly kWh figure or, far better, a 24-hour load curve.
• simulate_solar_tracks — price Israel's two mutually exclusive rooftop solar tracks against a real load shape, with payback and a recommendation. Which one pays more depends on WHEN a household consumes — the thing a roof-area calculator cannot see.
• get_city_consumption_benchmark — median monthly consumption, profile mix and 24-hour curve for a given Israeli city.
• get_national_load_curve — national demand by hour, day of week and season.
• classify_consumption_profile — classify a home as evening, night, morning, weekend or balanced, with peakiness and a night-shift opportunity figure.
• estimate_appliance_cost, size_air_conditioner, compare_ev_running_cost — running costs for appliances, air conditioning and electric cars at the current tariff.
• get_supplier_directory — every supplier and plan with its discount structure.
• how_to_export_my_iec_data — how a household downloads its own consumption file.
Privacy: no per-household data is reachable here. Every figure is either computed from the caller's own inputs or is a population aggregate published only where at least 25 analysed households sit behind it; a thinner cohort is refused rather than answered thinly. Nothing here writes, submits or contacts anyone.
