<![CDATA[PaHub v2.1 Doesn't recognise ENV III Unit]]>Having difficulty with getting my ENV III Unit recognised. Setup below:

UIFlow2.0 AtomS3R v2.2.8
PaHub v2.1 - DIP switches on factory setting.
ENVIII Unit

The ENV III works fine without the hub. but will not work in any assigned port, whether on it's own, or with other units.
Other I2C units work as expected. Only the ENV III has this problem.
All channels tried.

Has anyone else had this happen?
Thanks in advance for any help.

In addition to your code, I initialised the Pahub, and then changed the dip switch to 0x71. Additional units work fine when assigned to 0x71.
Thanks for the help!

I do not have an M5AtomS3R, but with my M5AtomS3 it works for me. See M5AtomS3_PaHUB_EnvIII_EnviV_UIFlow2.2.8 example in UIFlow2 Project Zone.

Make sure you power-cycle everything after changing the I2C address of PaHub. And maybe try another channel for the EnvIII unit?

Thanks
Felix

PaHub and ENV III unit share the same I2C address 0x70 by default. See here.

Thanks
