Advanced Features

EV Stop Trigger

Electric Vehicle Charging Override: Automatically stops all battery operations when your EV or other heavy appliance starts charging
- Overrules ALL active strategies to prevent power spikes and grid overload
- Configure by entering the entity_id of an input_boolean or on/off template sensor
- The trigger sensor should indicate when your EV or heavy appliance is actively charging
- When triggered, the system applies a Full Stop strategy until the sensor state returns to off
- Useful for preventing home battery discharge during high-power EV charging sessions
- Configurable through the Advanced Settings dashboard

Minimum Idle Time: Configurable minimum time before allowing battery grid relay disengagement
- Reduces relay wear and extends battery life
- Eliminates clicking/clacking noises during frequent charge/discharge transitions around 0W
- Configurable through Home Assistant dashboard
Hysteresis: Prevents excessive switching between charge and discharge mode around the 0 Watt line.
- If the PID output level lies within hysteresis, it will not switch from charge to discharge or vise versa.
- 0 = apply no hysteresis
Battery charge order: determines which battery gets charged first (Multi-battery only)
- Batteries gets charged in order. By changing which battery is first in order, you can optimize battery wear.
- Espescially during cloudy periods when the first battery takes the grunt of the charging and discharing.
- The Auto Cycle feature changes the order of the batteries automatically each night or each week
  - Auto Cycling occurs at 02:00 hrs daily, or 02:00 hrs Sunday morning.
  - Don’t want auto cycling? Select Cycle priority “Never”.
Controller Output Protection: Software protection based on battery maximum charge/discharge values
- Adjusts control output to stay within configured battery capabilities

Deadbands: Control loop only activates when P1 error is outside the deadband and P1 changes of more than 2%.
- Significantly reduces CPU load during stable operation
- Changing the P1 change for triggering the loop is done in Home Battery Start -> RBE:node 'On change (2%)'
- Changing the deadband can be done in Strategy Self-consumption -> F:node Deadband(15W)
Reporting by Exception: Action nodes only trigger when values actually change
- Reduces unnecessary Home Assistant calls and system load
- Note: the SET MODE action nodes have proven unreliable, for safety reasons the On Change RBE has been left out.

More than 4 batteries: Override or change input_number.house_battery_count and you are good to go.
- The dashboard supports 4 batteries out of the box, duplicate and edit these or create your own dashboard.
3-Phase self-consumption: if you require 0 W grid consumption on a per phase basis, the setup changes slightly.
```
Note: most homes get billed for the net total of all phases. If that is the case for you as well, ignore these instructions.
```
- Duplicate Home Battery Start to Home Battery Start L1, Home Battery Start L2, Home Battery Start L3 (one for each phase).
- Set the correct battery index in the Start Loop node. Keeping an eye on which battery is on which phase and thus which flow.
- Remove the Loop step and Loop until, tie the Mapping to the Battery strategy directly.
- Deploy as per normal instructions.
