Tuya App Integration Error

Hello - I am trying to connect Rainpoint valve to Homey Pro (Rainpoint is built on Tuya)

I have installed Tuya App latest version.
After entering the security code in Homey, the QR Code is displayed

Once I scan the code through the Rainpoint app I have this error message “Please use the designated APP to scan the code to log in”.

How can I sort this out?
thanks

By migrating your devices to the Tuya Smart or Smart Life mobile app. You can read a migration guide here:

Do you think it will work after the migration ?
The current RainPoint app is a Tuya based app.

Yes, it will. The error message states that you should use a supported app, which are Tuya Smart and Smart Life.
