With this product can I turn on, off standard light ?
Yes that’s correct.
Do You work for Aqara ? 🙂
No, I don’t. Why do you ask?
Because You know everything 🙂
I wish. We have one of the team in China, and he happens to know someone who is connected to Aqara.
Hi Simon. I like so much your news, but…Can you ad more information to the article or at least any link to know more about this particular product?
Maybe could be interesting to include it in my smart home but without more info it is difficult to analize it. Thank you
Hi, the information on the page is all I can find for the time being. There are plenty of these devices on AliExpress, but they all have the same info.
Do you think aqara devices may work on 220v 60hz grid?
It’s rated for 100-250v, but only at 50hz, so I’m not sure you would be able to use it.
The information above state that is 100-250 50hz not 60hz
My bad, I meant to type 50, not 60. Have corrected it.
I’ve looked into the issue of 50hz vs. 60hz a bit more and it seems you may be ok to use it. Here is an article referring to the issue;
Thank you for taking the time to search this.
You blog made me use RSS again, this time very restrictive to good content like yours
Hello Simon, I found this article saying that the Relay is compatible with 60hz
Is this article a official information?
Do you have any news about the Relay?
Where is the best to get a compile info about Aqara stuff, I just visited their website and there’s absence of product.
Hey, Does it give you options to select icos in Apple Home App? Or it is simple Light icon only?
From what I know, it is exposed as a switch, but there are options to change that. It does depend on how the manufacturer has set it up though, as the iDevices ‘switch’ is actually a smart plug, and that has the ability to show up as a Switch, Fan or light.

What is the reason for this strange three”inputs” ?
L + IN + IN ? I don’t see what this could be good for, as the wiring diagram implicates that no separate circuits can be used for the two switches.
I’m not really 100% sure about this device, but I know some people that are already using it. It’s a double relay switch so it can control the power to two devices.
Do you guys think this device would appear in the Apple Home app? or it will only be manageable in the Mi Home? I’m thinking to something like that to add “vocal” control to my Garage/gate doors, adding it to their control units (since I lack physical buttons).
According to someone who is already using one to control the pump for his pool (lucky him…), it gets exposed to HomeKit as standard as long as it’s going through the Aqara Hub.
Thanks a lot Simon! I will probably look for one and (once received in a few weeks), will write here my feedback. I hope I can configure, same as possible with the aqara switches, an automatism with on/off functionality (since I need the only a “pulse” signal, for the garage door)
It shouldn’t be an issue. The device works across the volt spectrum (100-240v) so it should be fine.
Can this be used to control a shutter/blind motor? (this means that when you action one relay, the other must stop so the motor do not get damaged). Thanks for the info
Anyone? Any answer? Thanks!
this device is a simple switch effectively (on/off), so in theory, as long as you can control the shutters/blinds (I’m assuming you mean outer shutters, right?), then this should work fine for turning the motor on or off. the only issue is making sure they stop automatically, so as not to damage the shutters, but that is a separate question that is down to the individual brand of shutter/blind.
I can not find this device in my Mi Home (for Android).
Are you sure, that this device for Mi Home (Mijia Gateway, not Aqara Gateway)?
Does have anybody information, can I add this device in domoticz? Thanks in advance!
You will find it in the Household Security section.
Can you use this device as a Blind / Shutter Up/Down relay?
Possibly, although usually devices like those require some kind of function to let them stop at a certain point when they reach the end, so probably not suitable.
Hi! Do you know if this is compatible with Apple HomeKit?
Yes it does work with HomeKit, as long as it is connected to the Aqara Hub.
Can this LLKZMK11LM relay be used as a “dry contact” device? Can it just connect two wires like a mechanical button does, independent of the voltage on the wires? For example, I have a low voltage, battery operated (e.g. 12V) device with a push button; can I use this relay and connect it to the push button to control it from the Aqara hub?
Yes, it does support dry contact. I am using it for that purpose.
Thank you Alexey, this opens my Xiaomi Zigbee system to the outside world.
To wire it properly, I assume that the red wire (on the pictures) between L and IN should be removed?
There are two contacts labeled IN. Does the left one correspond with L1 and the right with L2? The switches of the relay are between IN (left) and L1, IN(right) and L2, aren’t they? Then N and L will take the 220V supply presumably? S1 / S2 would be connected to L (240V) through a manual button, right? Is all this correct or am I messing up?
Correct, except that the two IN terminals on the relay are joined together in what’s known as the common on a relay. Based on the schematic, you can determine that there are two SPST (Single Pole Single Throw) relays inside. Here’s how it works.
