Note for Tuya app users
If you have been using the "Smart Life – Smart Living" app from Tuya for your Stadler Form devices, you can continue to do so. However, it's not possible to have a device stored and operated in both apps. We recommend switching to the Stadler Form app, as it will be further developed to provide an even better experience in the future. Please note that when you switch, you'll need to create a new account for the Stadler Form app and re-register your Stadler Form devices.


After you have connected to the Stadler Form app, it will take a few seconds for the measurement data to be displayed in the app.

The device can be disconnected from the app quite easily. Go into the app and delete the device. Or alternatively, hold down the Wi-Fi button on your Stadler Form device resp. the button for night mode on your Eva for 3-5 seconds. When the button or the water level indicator (Eva) starts to flash rapidly, you know that your device is no longer connected to the app.

Only one account can be connected to the device.

In your Stadler Form app account, however, you can share access to control your device with other people. To do this, go to the desired device, click on settings in the top right-hand corner and select "Share Device". Here you can grant access.

  • Restart your mobile phone

  • Switch off your router or Wi-Fi, wait 30 seconds and then switch it back on again. Then you can try again to add your device automatically, as described in the instructions

  • If a timeout still keeps occurring, add your device manually

Roger or Roger big: If the Wi-Fi symbol on the display is lit constantly, then your device is connected to the app.

Eva: If the water level indicator on the front lights up and Eva can be seen in the app at the same time, your Eva is connected.

Karl or Karl big: If the LED below the Wi-Fi icon is solid, your humidifier is connected to the app.
