How can I use a dry contact push button with the Gate SPI Wireless?

The Gate SPI Wireless can be connected to an external AC-powered push button (dry contact), separate from the built-in button. This allows basic control of the connected lighting system:

• Short press (<2s): Turns lights ON/OFF
• Long press (≥2s): Dims brightness
• Long press after >30s pause: Brightness increases again (always restarts upward dimming)
• Long press within 30s of previous dimming: Continues the dimming cycle
