Configuration website
The configuration website runs on the clock itself. Open it in the browser of a phone or computer connected to the same Wi-Fi network as the clock. It works only in Expert mode, after you have connected the clock to Wi-Fi.
Opening the website
When you connect the clock to Wi-Fi, the setup page shows the address and the Open clock settings button. Later, type one of these addresses into your browser:
- http://puri6-NNN.local, where NNN is the clock's serial number, for example http://puri6-42.local (Puri 4: http://puri4-42.local). It is the same name as the clock's setup network. Some Android phones don't support
.localaddresses; use the IP address there. - http:// followed by the clock's IP address, for example http://192.168.1.57. The setup page shows it after connecting; your router's list of connected devices shows it too.
While your phone is connected to the clock's setup network, you can also open http://192.168.4.1/dashboard.
Tip
Bookmark the address, or add it to your phone's home screen.
Password
The password keeps other people in your network away from the clock settings and firmware updates.
- First visit: the website asks you to create a password of at least 8 characters. Type it twice and tap Create password and sign in.
- Later visits: enter the password and tap Sign in. With Stay signed in the device stays signed in for 30 days; otherwise the website signs you out after 30 minutes without activity.
- After 5 wrong passwords, wait a minute before the next attempt.
- Change password is at the bottom of the Recovery tab, Sign out at the bottom of the menu.
Why a password?
The password is not our idea of making things complicated – the law requires it. Since August 2025, every radio device sold in the EU that connects to the internet must protect its settings and software against unauthorised access (Radio Equipment Directive, Delegated Regulation (EU) 2022/30). The UK and some US states have similar rules.
Without a password, anyone on your Wi-Fi – a guest, or a hacked device in your home – could change the clock's settings or install different firmware into it. That's why the clock asks you to create your own password the first time you open the website. Only you know it.
Important
Forgot the password? Do a hard factory reset: hold all three buttons for 15 seconds. It erases the password together with all settings and the saved Wi-Fi network; then connect the clock to Wi-Fi again and create a new password. A soft reset keeps the password.
Layout
The menu on the left (on a phone, behind the menu button) lists the tabs. Every change is applied and saved in the clock as soon as you make it; there is no Save button.
| Tab | What you set there |
|---|---|
| Date and time | Internet time, time zone, daylight saving time, 12h / 24h |
| Display | Digit transitions, colon, leading zero, cathode protection, status LED |
| Modes | Clock or countdown, what each tube shows |
| Night mode | Brightness, and a dimmer display at night |
| Network | Wi-Fi status, the setup network |
| Healing | Testing the tubes, healing unused digits |
| Firmware | Firmware updates |
| Recovery | Restart, forgetting the Wi-Fi network, factory settings, password |
At the bottom of the menu:
- Statistics – the clock's model, serial number, firmware version, Wi-Fi signal and power supply readings.
- Theme – light, dark, or following your device.
- Language – English, Čeština, Deutsch or Français. The language is saved in the clock, so the website and the setup page open in it on every device.
- Sign out.
When the browser loses the connection to the clock, for example while the clock restarts, the website shows Connecting… and reconnects by itself.
