Support for LLKZMK11LM Aqara wireless relay controller

[whitecube]

I bought one if this relays,( because i thought domoticz support it) for Ventilation Control Dew Point.
But it doesnt detect the device, i hope someone could implement the device.

thx!

Hi,

I bought some Aqara LLKZMK11LM Two-way Control Module Wireless Relay Controller, but they are not well recognized in Domoticz, currently they are considered as 2 devices :
device 1:
ID: 84AB
name : Xiaomi TempHum wireless relay
type: Temp + Humidity
subtype: WTGR800
data: 100.0C, 0%

device 2:
ID: 8502
name : Xiaomi TempHum
type: Temp + Humidity
subtype: WTGR800
data: 100.0C, 0%

So as they are not considered as actuators, no way to control them from domoticz...
I would expect to see them like a wired double switch actuator

I would be pleased to help, so if you need some info, just ask !

[whitecube]

you are right, i have two devices too.
they could be the relay. but domoticz detect it also as temphum...

[whitecube]

some news about this problem?

my logfile says:

seems your zigbee controller doesn't support it yet.
Zigbee2Mqqt does already.
Did you update to the latest version ?

[whitecube]

thanks for your answer.

Interesting, because i use the xiaomi gateway and this switch is from xiaomi and in the app i see it normal als a 2 channel relay.
and yes, i use the latest beta builds.

is it possible to use the Zigbee2Mqqt plugin with the hue or xiaomi gateway to extend the supported devices?

[HFman]

Quickly scanned the module :

https://github.com/domoticz/domoticz/bl ... ateway.cpp

Seems indeed not to be there yet.

And no, both are working indpent from eachother.
If you have the Zigbee2mqqt module ( 10 euro ?) you don't need the xiaomi hub any more.
But offcourse the app on your phone for xiaomi then also doesn't work any more.

[whitecube]

thank you!
i ordered yesterday the cc2351 stick, on tuesday i will test it

Hi,

I've the same issue with aqara LLKZMK11LM 2 , I'm very insterested by your solution, please advise.

Thanks in advance.

[whitecube]

it works, amazon delivered the item sooner

i ordered there a already flashed cc2351 usb stick.
read some installation manuals for mqtt etc and now its working!

but you have to make a factory reset of the devices. you cant connect the relay to xiaomi gateway AND the zigbee2mqtt.

now i have to figure out a good program for a dewpoint control (sometimes a damp cellar...)

[HFman]

Great ! I am also very happy with the MQQT2Zigbee.

Script should be quite basic right.. ?

Input are temp and humidity

Then you can easily caculate the dew point (or you take the one Domoticz calculates).

Then your check is :

if Temp Basement < then Dew point then switch on
else switch off

I assume running this script every 15 minutes would be sufficient.

Nice one for DZvents

[whitecube]

i have 2 xiaomi sensor outdoor and one in the basement.

a really basic logic would be dewpoint indoor > dewpoint outdoor -> fans on -> else switch off.

i realised it with blocky because i'm not a programmer...
but i think the fans will be on... really often.
there should be an interval like -> dewpoint indoor have a difference of 0,5 then dewpoint outdoor -> fans on for 20minutes -> else switch off for 20 minutes.

[yann500]

Could you give me a link for you cc2531? also installation manuals for mqtt? You can program in LUA and use that : commandArray['FAN']='On FOR 20'

It seems we need to get the gateway to put in the model name first as it's still empty in the latest update (1.4.1_175.0220). It should report 'lumi.relay.c2acn01'. I filed an issue via the Xiaomi app (Feedback).

I've the following messages when turning both channels on and off once:

Model seems to be empty so there is not much we can do then wait until this is fixed. Or is there another way of getting in contact with the Xiaomi developers?

Good afternoon, tell me if the situation with relay LLKZMK11LM support has changed? I see that the Xiaomi HUB sees it, but there is no choice of switches.

[Huupke]

You can use the relay only on the gateway itself but not through the API. This means that you (still) can't control it from Domoticz.

You could use the (double) wired switch though as an alternative.

[19leva89]

You have plans to add support for LLKZMK11LM Aqara wireless relay controller in future?

[19leva89]

There is already support in the Xiaomi gateway:

Version code: 272
Gateway ID：83872***
Zigbee channel：20

[Huupke]

On the API the model is still empty. Please submit a request on the forum: https://bbs.opencloud.aqara.com/

As soon as this is fixed I'll add the support in Domoticz.

[19leva89]

I wrote to Aqara technical support, they do not answer, a waste of time! Tell me, maybe you know, I read that in Home Assistance such relays can be connected and everything works there.
