OpenBeken - deactivating Physical Switch Button from Home Assistant: Ignoring Accidental Light On

Is there any way from Home Assistant to deactivate a physical switch button, so if someone accidentally turns on the light from the physical switch, it will be ignored?

That's a great idea! I've added a flag for that, it's called "child lock" and it makes device ignore all physical button and toggle presses:

Now, to use that, you need to send a proper MQTT packet from HA, do you know how to do that?

I know how to send an MQTT package, but what should I have as the topic and payload?
Can I assign a fake pin number to a switch on another channel and control it that way?

Well, you can always change Button role to something else (to None or anything) or assign a fake channel on your device. You can also control one device from another device and there are many ways to do it, including:
- sending a HTTP GET to IP with command like POWER ON by using SendGET command
- by using Tasmota Device Groups to group devices
- by using HA automation
It's up to you to choose the method that suits your needs best.

Regarding setting flags from HA, you can use the SetFlag command, see docs:
https://github.com/openshwprojects/OpenBK7231T_App/blob/main/docs/commands.md
The flag number for child lock is 41 and you can set it to on (1) or off (0).
SetFlag command can be send via MQTT or via HTTP, or entered manually, or also even it can be scripted. for example with HttpButton (you can create a custom button on your page that way).

I'm on the latest firmware but no flag 41

Sorry, it seems that the automatic build was not triggered this time! Let me try again, the new version should build automatically:

Thanks.

Just to be sure,

MQTT package should be:

Topic: "device_name/SetFlag41"
Payload: 1
??

Edit: if someone is looking to do the same this is the code you need

tap_action:
action: call-service
service: mqtt.publish
service_data:
topic: cmnd/device_name/SetFlag
payload: 41 1

Thanks, is there any way to add this function as a toggle lock or another entity in HA? (like zigbee2mqtt does)



I tried to add it as a relay and addChangeEvent and it works nice.

But it would be nice to instead of having a flag to enable or disable, that the flag creates the new entity to appear or not in Home Assistant, the child lock feature.

Ok, I found a better way to manually create a lock on MQTT config. Is there any way to get the state of a flag? So HA knows if it's locked or not?

lock:
- unique_id: "device_name_child_lock"
name: "device_name_child_lock"
command_topic: "cmnd/device_name/SetFlag"
qos: 1
payload_lock: 41 1
payload_unlock: 41 0
retain: true
availability:
- topic: "device_name/connected"

I can see how that can be a problem. I will need to think about it. Maybe I can add some simple mechanism for you to publish it. Something like $FLAG41 variable.

UPDATE: Working on it, do you know how to use publishInt?
