ASTRA WiFi Configuration



First Power On

After powering on, the ASTRA controller automatically creates a WiFi access point for initial setup. The configuration process takes 2-3 minutes.



Configuration Methods


Method 1: Web Interface (Recommended)

Step 1. Connect to ASTRA Access Point

  1. Power on the ASTRA controller
  2. On your smartphone/tablet/laptop, open WiFi settings
  3. Find network named ASTRA_XXXXXX-####
  4. XXXXXX — unique device identifier
  5. #### — last 4 digits of MAC address
  6. Example: ASTRA_3D5E26-7718
  7. Connect to this network (no password required)
Warning
Access point is active for only 3 minutes after power on. If you miss this window, press RESET button to restart.

Step 2. Open Configuration Page

After connecting to ASTRA WiFi:

  1. Open web browser on your device
  2. Navigate to: http://192.168.4.1
  3. WiFi configuration page will open
Tip
Some devices will open the page automatically. If you see "No Internet" warning — ignore it and stay connected to ASTRA network.

Step 3. Configure Your Network Connection

On configuration page:

  1. Select your WiFi network from discovered list
  2. Or enter network name (SSID) manually
  3. SSID is case sensitive!
  4. Enter password for your WiFi network
  5. Maximum 64 characters
  6. No special characters (* @ # etc.)
  7. No spaces
  8. Check "Show password" box to verify
  9. Click "Save" button


Step 4. Complete Setup

After saving settings:

  1. Controller will restart and connect to your network
  2. New IP address will be displayed
  3. Write down this address — you'll need it for control
