Door Lock Mechanism always reverts to unlocked status in HomeKit after opening Home.app

[bohtho]

A Door Lock Mechanism created via Homebridge-MQTT always reverts to unlocked status in HomeKit when reopening Home.app resulting in "Locking ..." because of the LockTargetState (if real last state is locked).

If I create the Door Lock in HomeKit via eg. node-red-contrib-homekit-bridged the state is remembered between activating home.app.

Can anyone reproduce ? This is the case in iOS 13.1 at least.

I don't use this service , but could you post your topic and payload JSON definitions.

I keep HomeKit in sync with, and control, a Danalock zigbee door lock.

Just {"name":"Døren","service_name":"Lås","service":"LockMechanism"} to topic homebridge/to/add.

I removed and created it via nodered-contrib-node-homekit-bridged instead to test, and then it keeps its state.

Hello people,

I have the same problem, I think this must be a security issue, because when I restart it goes back to Unsecured, so I made some variables to detect reboot and not have this problem for now, below is my configured accessory, thank you in advance .

            "accessory": "mqttthing",
            "type": "lockMechanism",
            "name": "Portao Pequeno",
            "url": "http://localhost:1883",
            "username": "admin",
            "password": "******",

                "getLockCurrentState": "hb/get/fechaduras/portaopequeno/current"
            },
            "lockValues": [
                "Unsecured",
                "Secured",
                "Jammed",
                "Unknown"
            ]
        }

I tried to make a publication before PAYLOAD to check if this UNSECURED or SECURED, and even then it didn't work ...
