Anotcher anomaly i use Pb.Hub and i connect wind speed meter to ch0 and Hall sensor to ch1.
I use digitalRead from ch0 to read IO 1 for speed meter and digitaRead ch1 read IO 1 to read hall
AND signal is mixed for both. I get readings from windspped meter when i use hall and hall reads inputs when i blow to windspeed meter. When i use both i get stupid info :/

and i cant in UiFlow to set the hall sensor to pb.hub i get only grove.
See picture

And another wired thing - when i use Pa.Hub with ENV III i get temp and humidity ok but pressure is -4826090,3. I cant get negativ pressure :>
When i connect direct to core 2 i get right value.

Hall Unit is a Pb Device aka Port B Device (the connector collar tell you what port it connect to) for the Hall sensor you need a PbHub.
