notify multiple HomeKit Apps when switch state has changed about hap-python HOT 6 OPEN

I think, the "HomeKit apps" will not be notified generally. The brigde is connected to the HomeKit and send/receive states.
The App connect the HomeKit an send/receive the states to/from the HomeKit. The Homekit mediates only. It seems to me, the second app have no reliable connection to the homekit. Can the second App switch and the first App see the action?

The effect is the same in Use case #3 even when switching the roles of Device/Homekit App #1 and #2. I can rule out connectivity issues.

Question: both clients Device/Homekit App #1 and #2 are on the same iOS release? And if you swipe down on the Device/Homekit (try refresh the view) nothing changed?

I have an equal use case, but using HTTPServer (example: /accessories/Http.py) to get the device state in reverse. If i'm switching manually, the device send {"aid":XXX,"services": {"Switch": {"On": true}}}' or false to the bridge. It works as expected.

@Pythonaire : Yes, both devices are on same iOS. I observed this behaviour during after multiple test/wipe/test iterations.

The http example hint is unfortunately still not an option, as said in my initial post, the switch does not have the capabilities to send something back.

could you try additional notify() in conjunction with get_value()?

That's my switch, with setter_callback and getter_callback, it works as expected.

class TestSwitch(Accessory):
    category = CATEGORY_SWITCH
    def __init__(self, *args, **kwargs): 
        super().__init__(*args, **kwargs)
        self.set_info_service(firmware_revision='0.0.3', model='XXX', manufacturer= 'XXX', serial_number="XXX")
        switch = self.add_preload_service('Switch', chars=['On'])
        self.UnitState = switch.configure_char('On') # bool needed
        self.UnitState.set_value(self.getState())
        self.UnitState.setter_callback = self.setState
        self.UnitState.getter_callback = self.getState()
        
    def getState(self):
        try:
            state = requests.get(url).json() # return int
        except ConnectTimeout as e:
            logging.info('**** request to {0} timed out: {1}'.format(url, e)) 
            state = 0
        return bool(state)

    def setState(self, value): # value is bool
        state = int(value)
        try:
            requests.post(url, data = str(value)) # need str
        except ConnectTimeout as e:
            state = 0
            logging.info('**** request.post got exception {0}'.format(e)) 
        return bool(state)
