Supplier's note

  1. Three Breakthroughs:

    • Learning Code Technology: Enables compatibility with 90% of existing remote systems, reducing setup complexity.
    • High Current Rating: The 10A/250VAC relay outperforms standard 5A modules, supporting industrial-grade devices.
    • EPR Compliance: Dual certification streamlines deployment across EU markets without additional testing.

  2. Version Selection Guide:

    • Base Model: Ideal for basic home automation (e.g., garage door openers) where fixed-code simplicity is prioritized.
    • Advanced Model: Best for hobbyists and small businesses needing copy-code flexibility for Arduino/ESP32 projects.
    • Pro Model: Designed for industrial users requiring long-range control (e.g., factory equipment) and full system interoperability.

With the Pro Model’s triple-industry-standard signal strength, you can manage outdoor machinery reliably. Pair its learning code with the 10A relay to automate high-power irrigation systems, ensuring uninterrupted operation.
