A Tessera tile that shows a scannable QR code for a Wi-Fi network. Its network name and password come from two Home Assistant input_text helpers, so changing either helper updates the tile without rebuilding the screen.

Set up

  1. In Home Assistant, create two Text helpers named WIFI_SSID and WIFI_PASSWORD.
  2. Put the Wi-Fi network name in WIFI_SSID and its password in WIFI_PASSWORD.
  3. Add this plugin to a screen in Tessera. Choose those two helpers when Tessera asks for them, then build the screen.
  4. In Layout, place the Wi-Fi QR tile from the Plugins group and resize it from 1 x 1 up to 3 x 3. A size of at least 2 x 2 is recommended for reliable scanning.

Good to know

  • The QR code uses the common WIFI: format with WPA security. Modern Android and iOS cameras can scan it directly.
  • The password is sent to the screen through ESPHome's Home Assistant connection. It is encoded in the QR code but is never printed as text on the display.
  • Anyone who can see the tile can join the network. Put it only on screens and pages intended for guests.
  • Hidden or open networks and WEP are not supported in this first version.
