Wi-Fi setup¶
A device with no network cannot be told about your network over the network. So a freshly flashed display that cannot get online broadcasts its own Wi-Fi instead, and you set it up from your phone. This is the same flow as a smart plug or a robot vacuum, with one advantage: this device has a screen, so it can show you what to join.
You do not need this if the device has Ethernet, or if you wrote a seed file before first boot. In both of those cases it goes straight online and never broadcasts anything.
What you do¶
- Power on the display and wait about a minute. It first tries to find a network on its own. Only when that fails does it start its own.
- The screen shows a QR code, along with a network name like
dashboard-assistant-4f2a91and a short password. - Scan the code with your phone's camera. That joins the display's network without typing the password. If scanning does not work, join the network by hand using the name and password on the screen.
- A setup page opens by itself. If nothing opens, browse to
http://10.42.0.1(the screen shows this address too). - Type your own Wi-Fi name and password and tap Connect.
- The display's network disappears and your phone returns to its usual one. That is the display joining your network. Watch the screen: it moves on to "Add this device in Home Assistant" and Home Assistant discovers it — provided the Dashboard Assistant integration is installed there.
Type the name exactly¶
The setup page asks you to type your network name rather than picking it from a list. That is a hardware limit, not an oversight: a Wi-Fi radio cannot search for networks while it is busy broadcasting one, so while the display is showing you its setup network it genuinely cannot see yours. Copy the name exactly as it appears on your phone, capitals included.
If the password was wrong¶
The setup network comes back. Rejoin it, and the setup page will tell you what went wrong, with your network name already filled in. A wrong password, a network that is out of range and a network that simply would not accept the connection all read differently.
When it appears, and when it does not¶
The setup network only ever appears on a display that has never been online. Once a display has reached your network even once, it never broadcasts again: if it later loses Wi-Fi it shows "Reconnecting" and waits. That is deliberate. The setup network has no protection beyond the password on the screen, so it only exists while there is nothing on the device worth taking.
It also does not appear if the Wi-Fi adapter cannot broadcast. Some USB Wi-Fi adapters cannot, and the display falls back to the old "Connecting" screen. Use a seed file or Ethernet on those.
To put an already-configured display back into setup mode, factory reset it from the admin page. Reset also clears saved Wi-Fi, which is what lets you move a display to a different house.
The setup network is not a back door
While it is up, the display refuses admin and pairing requests that arrive over it. Someone who joins your display's setup network cannot factory reset it, roll it back, or take its Home Assistant token.
