WIFI Module Configuration

Here we use Protoss PW11 / Protoss PW10 as an example.

1. After Protoss PW11 / Protoss PW10 is power on, use phone or notebook to find WIFI hotspot with name 'PW10', and connect it. Then click info icon to go to WIFI infomation page.

2. In the WIFI infomation page, find IPv4 default gateway.

3. In the browser, input IP address of IPv4 default gateway to go to configuration page. You can change display language at top right if needed. Both User name and Password is admin.

4. Click SYSTEM SETTINGS at left pannel, go to System Settings page.

If your WIFI Module has Multi-Host Option, turn it off.

5. In System Settings page, WAN Settings part:

DHCP: OFF

WAN IP: In Home Assistant -> Settings -> System -> Network -> Configure network interfaces -> WLAN0 -> IPv4, find Gateway address of Raspberry Pi. As shown in the example image, the Gateway address is 192.168.3.1. Choose an IP Address from the range 192.168.3.2 to 192.168.3.255, but make sure it's not already in use by another device. If the chosen address is occupied, select a different one.

Subnet Mask: 255.255.255.0

Gateway: Same Gateway address as Home Assistant WLAN0

DNS: 8.8.8.8

6. In System Settings page, WiFi Settings part:

WiFi Mode: AP+STA

STA SSID: Click 'Scan' button to find your WIFI hostspot and choose it

STA KEY: Password of your WIFI hotspot

Then click 'Submit' button at the bottom of the page to save settings.

7. In Serial Port Settings page:

Baud Rate: Usually it is 9600, but latest GP-PC200 BMS uses 115200 (RS232)

Data Bit: 8

Stop Bit: 1

Parity: None

Flow Control: Half Duplex

Ptotocol: None

8. In Communication Settings page:

Protocol: Tcp Server

Local Port: Leave the Port as default or assign a different Port of your choice, here we use Port 9999

9. In Others page, click 'Restart' button to make settings take affect.
