Built-in Web Server

The ADA P1 Meter device comes with its own web interface, which allows real-time monitoring of consumption and feed-in data.

This interface is accessible on the local network as follows:

Accessing the Web Interface​

Once the device has successfully connected to your Wi-Fi network, the built-in web server becomes available at:

http://okosvillanyora.local:8989/

This address uses mDNS (Multicast DNS) technology, which allows you to use a human-readable local hostname instead of remembering the IP address.

The web interface displays the following information:

  • Real-time power consumption
  • Feed-in power level
  • Current, voltage, and power per phase
  • Current meter readings
  • Dynamic charts and measurement logs

If the .local address doesn't work​

Some devices or networks do not support mDNS, which may cause the http://okosvillanyora.local:8989 address to fail.

This is most common on:

  • Windows devices (if Apple Bonjour is not installed),
  • Older Android devices,
  • Or routers that don’t support mDNS.

What to do in this case?​

  1. Find the device’s IP address via your Wi-Fi router’s admin interface:

    • Log in to the router (e.g., 192.168.0.1 or 192.168.1.1)
    • Look for the DHCP client list or “connected devices” section
    • The ADA P1 Meter usually shows up as okosvillanyora

  2. Enter the IP address and port directly into your browser’s address bar:

http://192.168.x.x:8989

(Replace x.x with the actual IP address, e.g., http://192.168.0.123:8989)

  1. Tip: It's recommended to assign a static IP to the device via your router’s DHCP settings, so the IP doesn't change after a reboot.

mDNS Support by Devices​

The following operating systems generally support mDNS:

  • macOS (natively)
  • iOS (Safari, Chrome)
  • Linux (if avahi-daemon is installed)
  • Android (recent versions, especially in Chrome browser)

The following systems may not support it:

  • Windows (unless Apple Bonjour is installed)
  • Older smart TVs and mobile browsers

Summary​

  • Default access: http://okosvillanyora.local:8989
  • Alternative access: via IP address, e.g., http://192.168.1.123:8989
  • If you can't connect, check your Wi-Fi router and mDNS support
