Validate the session and return the logged-in user, access level, current company, and assigned controller ids.

List the Baseline organizations (companies) this account can access. Use a companyId to scope baseline_list_controllers, or pin one via BASELINE_COMPANY_ID.

List sites and controllers (with model, firmware, subscription, device counts) across every organization the account can access. Pass companyId to limit to one org.

Live snapshot for a controller: overall status plus per-zone and per-device status codes (Running/Done/Off/Error/etc.) with decoded sensor readings.

Zone configuration for a controller: number, name, decoder serial, enabled state, designed/learned flow, and hydrozone agronomy details.

Active alarms and faults for a controller (valve short circuits, flow comm failures, dial-off, empty conditions, etc.), decoded with sender device and fault type.

Vendor proactive notifications (e.g. scheduled server-maintenance banners), as plain text.

Fetch a reporting time-series for a controller. Returns aligned timestamp/value points. Types: WaterUsage, ZoneRuntimes, ZonesActivity, ControllerActivity, MoistureLevels, Temperature, FlowMeterTotals, RainfallAccumulation, MeasuredFlow, ExpectedFlow. Dates are 'YYYY-MM-DD HH:mm'. Use id to scope to a single zone/device, omit for controller-wide.

Enumerate every device on a controller grouped by type (zones, flow meters, moisture/temperature/pressure sensors, master valves, pumps, rain gauges, event switches). Each entry includes the reportingSn to pass as deviceSn to baseline_get_history.

List watering programs for a controller with their last start/finish, duration, water used, next scheduled start/finish, and assigned zones. Sourced from the controller config.

Current live reading for one enumerated device, by its reporting serial (from baseline_list_devices: serialNumber, or decoderSN for a zone). Returns the decoded status and key/value readings, plus a primary value where meaningful: pressure sensor → PSI, moisture sensor → %VWC, flow meter → real-time water usage, zones/valves/pumps → run state. Pair with baseline_get_history for the same device's trend.

Modern reporting time-series for a single device. Kinds: pressure, zone, flow, moisture, temperature. This is the source for historical PRESSURE and for per-zone/flow/moisture/temperature trends. deviceSn is the device's reporting serial (from baseline_list_devices: serialNumber for sensors/meters, decoderSN for zones). Dates accept ISO-8601 or YYYY-MM-DD. Returns max/min/average/median plus per-bucket points.
