Xiaomi JY-GZ-01AQ `linkage_alarm` not working

Danit2 commented 2 years ago

What happened?

I have two Xiaomi JY-GZ-01AQ smoke detectors.

On both i have switch on the function linkage_alarm on.

Now i have tested both of the smoke detectors and the function linkage_alarm is not working. Only on one detectror the alarm comes.

Is this a problem of Z2M or of the firmware from the detector? Have someone else the same problem?

What i have to do, tht this is working?

Thanks.

What did you expect to happen?

When one of the detectros have smoke, that all others also sound the alarm.

How to reproduce it (minimal and precise)

Switch the linkage_alarm on and simulate smoke.

Zigbee2MQTT version

1.27.0

Adapter firmware version

20211217

Adapter

Sonoff USB Stick CC2652P

Debug log

No response

Yes, the linkage_alarm option only sends a notification, but does not trigger an alarm on another similar device, so I created a PR that adds the ability to manually activate/deactivate the buzzer.

Cool, thanks for your work. I will test it after the next release.

@Otnow How can I use the manual activation to trigger the alarm on other detectors if one detects smoke?!

You first need to enable the linkage_alarm option for all smoke/gas detectors, and then use the automation in your smart home system to enable the alarm.

linkage_alarm Is already enabled in all 3 sensors, but when I tested it it didn’t sound on the other sensors, I’m using HomeKit via HB, can’t find a way to enable alarm sound for other sensors.

As I said earlier, for this you need to create automation in your smart home system:

@Otnow I'm using HomeKit, the Buzzer_manual_alarm is not showing to create any automation!!!!

I don't use HomeKit, so unfortunately I can't help 🤷‍♂️

Thank you for your help, I guess I've to wait for an update that can expose the Manual alarm to Homebridge/Homekit

@Otnow Thanks for the option to set the buzzer.

However: I wonder what's the purpose of linkage_alarm (and linkage_alarm_state) then? If it's anyway to be done in NodeRed, one can just as well read smoke and trigger buzzer, no? So why linkage_alarm then?

lost-carrier commented 1 year ago

@Otnow a maybe worth mentioning experiment I just did:

Removed 2 sensors from Zigbee2mqtt and connected to Aqara E1 Hub
Then turned on the linked alert for both
Created smoke -> 1st sensor raised alert, a few seconds later the linked one also alerted
Waited air was clean (and "mute" timed out)
Unplugged Aqara E1 Hub
Again created smoke -> 1st sensor raised alert, linked one stayed quiet

I still wonder what's the purpose of linkage_alarm (and linkage_alarm_state), but I guess the original Aqara stuff does the same as NodeRed would do.

...anyone happen to know any Z2M compatiblant smoke sensor that could directly trigger its neighbours? (without any Hub/Zigbee2Mqtt online)

Otnow commented 1 year ago

@lost-carrier, that's right, unfortunately, these sensors cannot communicate directly with each other and the Aqara hub controls the buzzer.

linkage_alarm must be enabled in order to be able to manually control the buzzer, otherwise it and linkage_alarm_state are generally not useful, but they are implemented in the code, because they are part of the functionality of the sensor.

lost-carrier commented 1 year ago

Ah, I see... makes sense (...at least to some extend... ;-) )

Thanks for that explanation.

@Otnow I got a new smoke alarm. This has a new firmware. (Firmware date: 20220617)

Is it possible for you to get this firmware so I can update my other smoke alarms? I would also be interested in the changelog. Perhaps something has changed in the linkage_alarm?

Many Thanks.

The URL of the firmware file can be retrieved from the Aqara app, but unfortunately there are no updates available for this sensor at the moment, so all that remains is to wait for it 🤷‍♂️

I have created a blueprint in home assistant to achieve this functionality:

https://community.home-assistant.io/t/aqara-smoke-detector-linkage-alarm/517656

Danit2 commented 1 year ago

@ciB89 Thanks for your blueprint. I do this at the moment over Node-Red but i will try your blueprint. But can you explain a little bit more what you bluepint does? The actions that can be triggered? The notification that will come? Some Pictures?

And one thing that i have found now: Why i can only notif one device? i would like to notife my wife also?

ciB89 commented 1 year ago

Once the alarm is triggered (smoke) it will manually set all the alarms on all the connected devices and will send a notification to a mobile device, telling it which room (as long as each device has its area assigned to it) has triggered the alarm and giving the option to deactivate the alarm again (in case of a false positive).

There are two possible triggers, the other one is when the alarm is manually disabled it disables all the alarms on all the other detectors. It's basically another automation, but the way I set it up you only need the one blueprint.

There is only one notify device because you cannot properly use multiple devices here. The better way is to actually create a notify group and use that in the blueprint.

I need to update the description, I know, it's very basic ;) - I did not even mention that areas need to be assigned to the devices and the linkage_alarm setting must be enabled/set to true.

My Zigbeemqtt has the following

Firmware build date 20220617 Firmware version 2019www. Manufacturer Xiaomi Model JY-GZ-01AQ

I only have one sensor for testing, the test mode triggers correct from HA but manual on does nothing for me.

Turning that on should it actually trigger ?

Cossey commented 1 year ago

During the absence of a smoke alarm, the buzzer can be manually alarmed ("alarm") and disalarmed ("mute"), but for this "linkage_alarm" option must be enabled I can confirm that when Linkage Alarm is OFF, neither the alarm or mute options will work - but when ON they will work. So technically it does have a linkage to other alarms, but the zigbee coordinator must trigger these other smoke alarms. I was also hoping this could directly notify other devices in the case the coordinator goes offline.
