Hi @felmue,
thanks for response - yes I have tried different ports on PA.hub so between two uiflows sensors might have different port values.

best,

Greetings @felmue!
Thank you for your reply,
Even if I space apart both sensors and direct them in different spots - they still get weird readings. As soon as I disconnect one of them from pa.hub one label gets proper readings - and other gets very simillar reading to first label (even though it is linked with disconnected sensor).
Below screenshot of readings with one sensor disconnected from pa.hub - and both labels change as soon as I get some object near the connected sensor.

For UIflow 1 code is:

from m5stack import *
from m5ui import *
from uiflow import *
import time
import unit


setScreenColor(0x222222)
tof4m_0 = unit.get(unit.TOF4M, unit.PAHUB0)
tof4m_1 = unit.get(unit.TOF4M, unit.PAHUB2)






label0 = M5TextBox(43, 36, "label0", lcd.FONT_Default, 0xFFFFFF, rotate=0)
label1 = M5TextBox(45, 88, "label1", lcd.FONT_Default, 0xFFFFFF, rotate=0)


while True:
  label0.setText(str((str('odl 1 ') + str(((str(((tof4m_0.get_single_distance_value) / 10)) + str('cm')))))))
  label1.setText(str((str('odl 2 ') + str(((str(((tof4m_1.get_single_distance_value) / 10)) + str('cm')))))))
  wait_ms(500)
  wait_ms(2)

When I try to run it on UIflow 2.0 with pa.hub I get error:

Traceback (most recent call last):
File "<stdin>", line 29, in <module>
File "<stdin>", line 20, in setup

This is my code for uiflow 2 - and it does not work

import os, sys, io
import M5
from M5 import *
from hardware import *
from unit import TOF4MUnit
from unit import PAHUBUnit



label0 = None
label1 = None
i2c1 = None
pahub_0 = None
tof4m_2 = None
tof4m_0 = None


def setup():
  global label0, label1, i2c1, pahub_0, tof4m_2, tof4m_0

  M5.begin()
  Widgets.fillScreen(0x222222)
  label0 = Widgets.Label("label0", 44, 65, 1.0, 0xffffff, 0x222222, Widgets.FONTS.DejaVu18)
  label1 = Widgets.Label("label1", 43, 111, 1.0, 0xffffff, 0x222222, Widgets.FONTS.DejaVu18)

  i2c1 = I2C(1, scl=Pin(22), sda=Pin(21), freq=100000)
  tof4m_0 = TOF4MUnit(PAHUBUnit(i2c=i2c1, channel=1), 0x29)
  tof4m_2 = TOF4MUnit(PAHUBUnit(i2c=i2c1, channel=0), 0x29)


def loop():
  global label0, label1, i2c1, pahub_0, tof4m_2, tof4m_0
  M5.update()
  label0.setText(str((str('Odl1 ') + str((tof4m_2.get_distance)))))
  label0.setText(str((str('Odl2 ') + str((tof4m_0.get_distance)))))


if __name__ == '__main__':
  try:
    setup()
    while True:
      loop()
  except (Exception, KeyboardInterrupt) as e:
    try:
      from utility import print_error_msg
      print_error_msg(e)
    except ImportError:
      print("please update to latest firmware")

Thank you for help,
best,

Greetings I am trying to connect 2 TOF4m sensors to M5Stack Core Basic via Pa.hub.
Below basic blockly schematics. As soon as I connect second sensor to PAhub- labels react in a weird way. For example: If I put something near one of sensors - both labels change and show some random distance. As soon as I connect only one sensor to pahub - everything works fine and distance information works.
