I had the same problem as stefan24:  
[Problems with Sensehat on Pi4 with Bookworm (Python3) and NR 4.0.3](https://discourse.nodered.org/t/problems-with-sensehat-on-pi4-with-bookworm-python3-and-nr-4-0-3/92220)

The cancellation of the connection to the sense-hat node is caused by the warning message ‘DeprecationWarning: activeCount() is deprecated ...’ in the sensehat.py file.  
In the file **sensehat.py** , the deprecated method

> activeCount()

must be replaced by the new method

> active\_count()

in line 130.

As soon as this change has been made, the connection is no longer interrupted.

Hi Paul

Thanks - will patch it later today.  
Good luck with the Norovirus - lots of it about over here at the moment as well (as well as RSV and Covid and general winter flu... quadruple whammy! ) . Hope you manage to avoid them all...  
Thanks for the update

Published as v 0.2.0... please can you try it again to double check if you get a chance - but it was just that one line change so hopefully ok...

Hello dceejay,  
I have just replaced my old Sense Hat version 0.1.5 with the new version 0.2.0. It works as desired. Thanks for creating the new version.
