Could you please show an example?

Hi, this is OK but the black circle is over the red one, how can we put the black circle behind as background?

Hi everybody, thx for helping, I’ll buy Pyto and try.

Thx for trying, I’ll wait!

Thx, the question is now if Pyto can read the barometer sensor value, below a short code which runs fine under Pythonista:

from objc_util import ObjCInstance, ObjCClass, ObjCBlock, c_void_p

pressure = None

def get_pressure():
  
  def handler(_cmd, _data, _error):
    global pressure
    pressure = ObjCInstance(_data).pressure()

  handler_block = ObjCBlock(handler, restype=None, argtypes=[c_void_p, c_void_p, c_void_p])

  CMAltimeter = ObjCClass('CMAltimeter')
  NSOperationQueue = ObjCClass('NSOperationQueue')
  if not CMAltimeter.isRelativeAltitudeAvailable():
    print('This device has no barometer.')
    return
  altimeter = CMAltimeter.new()
  main_q = NSOperationQueue.mainQueue()
  altimeter.startRelativeAltitudeUpdatesToQueue_withHandler_(main_q, handler_block)
  try:
    while pressure is None:
      pass
  finally:
    altimeter.stopRelativeAltitudeUpdates()
    #print('Updates stopped.')
    return pressure.floatValue()*10

pressure = get_pressure()
print(pressure)

I just downloaded it but my trial period already expired because I probably already tried it some times ago and since I don’t know if it works, I don’t want to buy it. If you’ve it, could you try if it runs when iPad is asleep?

I don’t know PyTo but I will try, thx in any case

@cvp I’m not sure to understand what you mean, but calling a pythonista script from a shortcuts or an automation requires the iPad to be awake

Yes, it works but only if the iPad is awake

Yes but only everyday, I want to read the value of the barometer sensor every hour, I can get this value with Pythonista. I didn’t find a way to get this information in shortcuts nor in JS (scriptable).
I found also a way to do some tasks every hour in shortcuts but I don’t find a way to get the barometer sensor value.
