Engine 1 x dimmer + 1 x bypass¶

This package implements the engine of the solar router which determines when and how much energy has to be diverted to the load, with a bypass function for maximum efficiency.

When the regulator is intensively used for an extended period, the regulator will tends to overheat. This engine is designed to avoid this issue by activating a bypass relay and turning off the regulator when the regulator is opened at 100% for an extended period. To avoid flickering, the bypass relay is activated only when the regulator is opened at 100% for a number of consecutive regulation.

Engine 1 x dimmer + 1 x bypass calls every second the power meter to get the actual energy exchanged with the grid. If energy produced is greater than energy consumed and exceeds the defined exchange target, the engine will determine the percentage of regulator opening and adjusts it dynamically to reach the target. When the regulator reaches 100% for an extended period, the bypass relay is activated for maximum efficiency.

Engine's automatic regulation can be activated or deactivated with the activation switch.

How to wire the bypass relay¶

• Live on the Bypass Relay Common (COM) and on the Relay to the Live Input of the Regulator
• Normally Closed (NC) floating
• Normally Open (NO) of the Relay to the Load Output of the Regulator (or directly to the Load)

Router Level vs Regulator Opening¶

The solar router uses three distinct but related level controls:

• Router Level: This is the main system-wide control (0-100%) that represents the overall routing state. It controls the LED indicators and energy counter logic. When automatic regulation is enabled, this level is dynamically adjusted based on power measurements.

• Regulator Opening: This represents the actual opening level (0-100%) of the physical regulator. By default, it mirrors the router level since there is only one regulator. While it can be controlled independently, changes to regulator_opening alone won't affect the router_level or trigger LED state changes.

• Bypass Relay: This represents the actual state (ON/OFF) of the physical bypass relay. When the Regulation is enabled, this relay automatically turns on after the duration Bypass tempo defined in Home Assistant. When the Regulation is disabled, you can manually trigger this relay to fully energized your load, LEDs and Energy Counter (if enabled) will not be triggered. You can also set the Router Level to 100, this will enable the relay, fully energized your load, trigger LEDs and Energy Counter.

When this package is used it is required to define green_led_pin and yellow_led_pin in vars section as show in the upper example.

• xxx_led_inverted can define is led is active on high or low signal and is optional.
• hide_regulators allow to hide or show regulators sensors from HA and is optionnal.
• hide_leds allow to hide or show leds values from HA and is optionnal.
