🏠 HA integration · Five steps to Home Assistant

Connect to Home Assistant over Wi-Fi to manage device entities and automations.

Connect Wi-Fi and power

The HA version includes Wi-Fi and creates an access point when powered on. Connect a phone or computer to the device hotspot beginning with HA (password: 12345678).

Configure the device network

After connecting to the HA-xxxx hotspot, the setup page opens automatically. If it does not, open 192.168.4.1 in a browser. Connect the device to the 2.4 GHz network used by the HA host.

Discover the device in HA

Open the devices and management page in Home Assistant. Find the automatically discovered device under the ESP integration and select Configure to add it. Device entities are created automatically, without manually writing configuration.

Create automation scenes

Add device entity cards to the HA dashboard and create automations and scene interactions as needed.

Reset the device

If the device cannot reconnect to its configured network for about two to three minutes, it resets automatically. You can also select RESET in the HA interface.

📡 Communication protocol · DL02 simulated Modbus protocol (for page effect verification only)

Status: DEMO / SYNTHETIC. The following registers, addresses, and values are simulated data and cannot be used for real device wiring, debugging, or delivery. Communication parameters include: protocol Modbus RTU (simulated), physical interface RS-485 two-wire (simulated), default address 1 (simulated), baud rate 9600 bit/s (simulated), data format 8 data bits, no parity, 1 stop bit (simulated), supported function codes 03 read holding registers, 06 write single register, 16 write multiple registers (simulated).

Operating mode

Mode value	Name	Description
0	Manual mode	Control output by local switch (simulated)
1	Bus mode	Control output by Modbus command (simulated)
2	Interlock mode	Local input and bus command are both effective (simulated)

Data value notes

Within 100 meters: 9600 bit/s, use a 120Ω termination resistor at each end of the bus (simulated example).
100–500 meters: it is recommended to use shielded twisted pair and a bus topology (simulated example).
Over 500 meters: should be re-verified by an engineer based on cable, number of nodes, and on-site interference (simulated example).
