This guide allows you to optimize power consumption by configuring load management rules based on electricity tariffs. The controller will dynamically switch or adjust devices according to your settings, helping you reduce electricity costs.

Step 1: Current Tariff Rates & Global Settings

1.1. Setting Tariff Rates

  • Define electricity tariffs based on time slots.
  • Two types of tariffs can be configured:
    • High Tariff (Peak hours when electricity is expensive)
    • Low Tariff (Off-peak hours when electricity is cheaper)

Enter tariff schedules manually on Tariffs Setings.

1.2. Global Load Management Settings

Total Load Limit (kW)

  • Set a maximum power consumption limit for the home electricity system.
  • If total power consumption exceeds this limit, the system will gradually disable devices based on priority.

Wi-Fi Unavailable Behavior

  • Choose what happens if the Wi-Fi connection is lost:
    • Continue using last known settings
    • Switch to a predefined emergency mode (e.g., disable non-essential devices)

Device Priority Settings

  • Define the order in which devices will be disabled if the Total Load Limit is exceeded.
  • Use select number to rank devices from highest to lowest priority.
  • Example:
    1️⃣ Underfloor Heating
    2️⃣ Water Heater
    3️⃣ Battery Charger
    4️⃣ Other Devices

Step 2: Configuring Load Management Rules

Each device (Relay 1, Relay 2, Dimmer 1, Dimmer 2) can be configured separately for High Tariff and Low Tariff periods.

2.1. Relay Control Rules

For Relay 1 (e.g., Water Heater) and Relay 2 (e.g., Battery Charger):

  • High Tariff
    • [✔] Keep OFF during peak hours
    • [✔] Allow operation only if excess solar power is detected
    • [✔] Reduce operation time (e.g., only allow heating for X minutes/hour)
  • Low Tariff
    • [✔] Allow operation freely
    • [✔] Delay activation until off-peak hours

2.2. Dimmer Control Rules

For Dimmer 1 (e.g., Underfloor Heating) and Dimmer 2 (e.g., Adjustable Heater):

  • High Tariff
    • [✔] Reduce power output (e.g., limit to 15%)
    • [✔] Disable heating if power limit is exceeded
  • Low Tariff
    • [✔] Allow full power operation
    • [✔] Adjust output based on available energy

Each rule is optional, allowing users to tailor device behavior to their specific needs.

Step 3: Daily Schedule Overview & Summary

3.1. Tariff Schedule Visualization

  • A color-coded hourly grid will display the tariff schedule.
    • High Tariff hours
    • Low Tariff hours
    • Custom rules applied

3.2. Settings Summary

  • Display a table with configured rules for each device.
  • Users can edit settings directly from this block.

3.3. Control Buttons

  • Save & Apply Settings (Confirm changes and activate)
  • Reset to Defaults (Restore factory settings)
  • Preview Schedule (Simulate device behavior with current settings)

Final Notes: Controller Behavior Based on Settings

During High Tariff Hours:

  • Relays will turn off unless exceptions are defined.
  • Dimmers will reduce power output to minimize costs.
  • If total load limit is exceeded, devices will be disabled based on priority order.

During Low Tariff Hours:

  • Relays will turn on freely (if scheduled).
  • Dimmers will increase power output.

If Wi-Fi is Lost:

  • Controller will follow the predefined Wi-Fi Unavailable Behavior setting.

This configuration system ensures optimal energy efficiency, preventing unnecessary consumption during peak tariff hours while maximizing usage during lower-cost periods.
