[Introduction]：The wireless intercommunication switch is a terminal device that uses LoRa modulation technology to achieve wireless remote transmission of switching values. It supports collecting switching inputs (DI) and controlling relay outputs (DO). Operating in the 850.125-930.125 MHz frequency band, its core function is to achieve remote synchronous control. It requires no wiring and is highly user-friendly, allowing users to quickly integrate it into their own systems. It has a DC input voltage of 8-28 V and is coated with a conformal coating that is resistant to mold, moisture, and salt spray.

LED indicator and button description
| port | LED indicator color | illustrate |
| PWR | Blue LED | Power indicator light, always on when powered on, off when no power |
| LINK | Yellow LED | 1 to many (including 1 to 1) - bidirectional (when the devices have the same number of channels): |
| l As long as one slave is successfully connected to the master, the LINK indicator of the master will be on; | ||
| After the slave device is successfully connected to the host device, the LINK indicator of the slave device will be on; | ||
| 1 to many - two-way (different number of channels, each channel of the host is independently controlled by the slave): the host LINK indicator flashes several times according to the number of devices connected (cycle 300ms, after flashing, it goes out for 1s, and then flashes again). For example: if 3 devices are connected, the LINK indicator flashes 3 times according to the cycle, then goes out for 1s and flashes again; | ||
| STATE (indicator light) | Blue LED | Host: The indicator light is always on; |
| Slave: indicator light flashes slowly; | ||
| Pairing: indicator light flashes quickly; | ||
| Not paired: the indicator light is off; | ||
| STATE (button) | White buttons | 1. Press and hold for 2 seconds to enter pairing mode; |
| 2. Press and hold for more than 6 seconds to restore to factory settings; | ||
| 3. Press and hold to cycle through the pairing state and reset state; | ||
| 5. In pairing mode, short press to exit pairing mode | ||
| DI1-DI8 | Green LED | Device switch input data indication, normally on means there is input, normally closed means there is no input |
| DO1-DO8 | Red LED | Each of the 8 relay output switch indicators corresponds to the 8 relay outputs; normally on indicates output is in progress, and normally closed indicates no output. |
