⚙️ BioChemSolenoidValve Initialization Parameters

When creating a BioChemSolenoidValve, you must specify how the valve connects to a device that provides a Relay component — either as a single-channel or multi-channel relay controller.

Parameter	Type	Required	Description
support_platform	str	✅	Identifier of the relay component that controls this valve. It must match an existing entry in Relay.INSTANCES, formatted as device_name/relay_name. Example: mpibox/relay-A
channel	int, optional	⚙️ Only if multi-channel	The relay channel number (1–32) to use. Required only when the relay component supports multiple channels (e.g., a switch box or multiplexer). For single-channel relays, this can be omitted.
normally_open	bool, default = True	❌	Defines the valve’s electrical and flow logic. • True → Valve is open when unpowered (Normally Open). • False → Valve is closed when unpowered (Normally Closed).

[device.my-solenoid]
type = "BioChemSolenoidValve"  # This is the device identifier
support_platform = "mybox/relay-A"  # Name of the `device/component` instance to bind to (key in Relay.INSTANCES`).
channel = 1  # Relay channel index (1–32) on the switch box.
normally_open = 1 # (optional) : 0 - False and 1 - True, default 1. Electrical/flow logic of the valve.
                  # If True, the valve is open by default (no power). If False, the valve is closed by default (no power).

💡 Notes

• The support_platform must reference a device that already exposes a Relay component.

• The relay component can be multi-channel (e.g., controlling multiple valves) or single-channel.

• The communication between the valve and relay is managed automatically after initialization (await valve.initialize()).
