Issue with tuya ZG-227Z : Entity not available

Hi guys,
i’m having an issue with my new tempereature and humidity sensor… I’m using a tuya ZG227Z with z2m and a sonoff key.

I paired it without any problem.

On z2m everything looks good. Temperature etc ok.

On mqtt side no data…

When I click on "temperature it is said entity not available.

If I listen to topic on mqtt side everything looks good. It does receive the packets with data in it.

I’m a bit lost…

Thanks for helping.
