+# engine_1dimmer_1bypass
+
+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_1dimmer_1bypass** 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)
+
+!!! Danger "Follow the wiring instructions"
+    Do not plug the Regulator Live Input to the Normally Closed (NC) of the relay ! Your load would be de-energized while switching the relay, potentially creating arcs inside the relay.

+
+- **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.

+```
+
+!!! tip "Adjusting Bypass Tempo"
+    The `Bypass Tempo` determines how many consecutive regulations at 100% are needed before activating the bypass relay. A lower value will make the bypass more reactive but might cause more frequent switching (flickering). Because there's roughly 1 regulation per second, `Bypass Tempo` can be approximated as the time in second with the regulator at 100% before which the the bypass relay is activated.
