Keeping Smart Lights Always Powered (Aqara Decoupled Mode Solution)

[US-EddieDaYankee]

I wanted to share a smart home win that took way longer than it should have—but ended up being incredibly satisfying.

A couple of years ago, I installed a pair of Juno Speaker Lights on my patio. They’re awesome—color-changing lights with built-in Bluetooth speakers. I was excited to bring them into my smart home setup, but I quickly ran into two major issues.

First, the manufacturer told me the only supported smart home ecosystem was SmartThings. That was limiting, but I made it work. The bigger problem was power. These lights need constant power, but they were wired to a standard wall switch. Every time someone flipped the switch, the lights lost power, went offline, and if left off too long, became unresponsive—forcing me to re-add them from scratch. Not exactly “smart.”

I dealt with that setup for nearly two years. I looked into switch covers, smart buttons—nothing felt clean or practical for a shared household.

Then things started to click.

I discovered I could bring the speaker lights into Home Assistant using Zigbee2MQTT and a Zigbee coordinator. That alone was a huge step forward. I grouped the lights and exposed them to HomeKit, finally making them part of my broader ecosystem.

But the wall switch problem still remained.

That’s when I realized what I actually needed: a wall switch that acts like a smart button—something that doesn’t cut power, but still lets anyone walk up and control the lights.

Enter Aqara.

The Aqara Smart Wall Switch (no neutral, single rocker) turned out to be exactly what I needed. Three key things made it the perfect solution:

1. Zigbee compatibility – I added it to Home Assistant via Zigbee2MQTT and exposed it to HomeKit alongside my lights.

2. Decoupled Mode – This disables the relay, so the switch no longer cuts power. My speaker lights stay powered 24/7.

3. Button event support – The switch press is exposed as an event, which I used to trigger an automation to toggle the lights.

Now everything works exactly how it should.

I can control the lights remotely through Home Assistant or HomeKit, and anyone in the house can still use the wall switch like normal—without breaking anything.

It took persistence (and a lot of trial and error), but this ended up being one of the most satisfying smart home fixes I’ve done.

Hopefully this helps someone else trying to solve the “smart device + dumb switch” problem.

Very helpful sharing! I’ve run into a similar issue before… Every time I turned off the switch, the smart device would lose connection. Then I started using an Aqara Mini Switch, which lets me control the switch while keeping the device connected!

This has been such a headache for me! You really saved the day.

Hello, I will write my setup to solve this problem in a separate topic later.

[DEChrisE]

Thanks for the great description of your problem - smart lights and smart switches / dumb switches is always a struggle

[denis.w]

Thank you for sharing your workaround! I think a lot of people will experience something like this. At least I did in the past and the decoupled mode is a huge plus to sort that out and power the lamps 24/7

Nice write up, should be mentioned that decoupled mode requires neutral wiring. I’ve got a guide in the works for achieving similar results with no-neutral wiring often found in older houses.

Thanks for reminding me. I made an edit to my post.

My first experience with “decoupled mode” actually came from inovelli smart switches that I bought a few years ago for this exact scenario. I’ve only bought 3 (very expensive) and like them but don’t love them.

Since I’ve recently gotten deep into the Aqara ecosystem I’ve been replacing switches with the VERY versatile switches that aqara offers!!

My coolest trick is that I put an H2 Dimmer switch in a room to control a Smart Pendant Light from Govee. Now what’s cool about this switch is that ALL THREE BUTTONS can be decoupled!! So, in Home Assistant, I have toggle automations that make one control the Pendant, one control my daughter’s play room lights and one to control the kitchen light!!! So I just made one switch control THREE different rooms!!

Yeah, Aqara has definitely won my home!!

Thanks for the detailed description of your automation.

This is my lighting solution with a smart switch + smart lamp. Setting up the H2 smart switch paired with a smart lamp. One of the connection options

Decoupled mode is a “power” feature for sure. Great way to level up a smart home.

Thanks for sharing. No more tapes over the switches. [quote=“US-EddieDaYankee, post:1, topic:287726, full:true”]

Great write up, it’s such a clean way to achieve a happy smart home for all!

[US-EddieDaYankee]

Thanks. I can’t believe it took me so long to get to this solution. The speaker lights were the main obstacle, but they are so worth it.

I probably should just post this for everybody but I was wondering when it comes to additional features like a double click, perhaps that
a. goes through different shades of white that are predetermined…
Or
b. maybe switch between circadian lighting and your favorite white temp.
c. Maybe one is the toggle through predetermined colors and the other one predetermined whites

I guess my question is, can you triple click? This could get carried away obviously but is that an option?

I’m guessing that holding it down is an option,

I suppose my question is, is there a limit with various clicks when it comes to maybe activating particular colors or scenes?
Single click, double click, triple click (moving towards ridiculous), and hold down for perhaps 2 to 3 seconds or indefinitely until it reaches full brightness or as dim as it goes.

And to bring this to a completely obnoxious question, what about allowing so if you press the two dimmer buttons on the three button switch at the same time. Could that perhaps do something drastic such as a reset or maybe that would trigger an entire scene

Just curious what the couple capabilities can be!!

Thanks!!!

Another way of doing it would have been to make the lights available over Matter, using HA. Then you could have added the lights to Apple Home and Aqara controller, such as the M3, and then you could have set up inside the Aqara app.

This is how I’ve done it with an Aqara switch and a Nanoleaf bulb.

Woo hoo! Good work.

The pressure was on to get the painters tape off our switches here. The UK wiring standards have “switched live” behind our wall switches - no neutral.

I got the same result as you by taking out the switch and using a Wago connector to effectively make the circuit permanently on. I then mounted a H2 Wireless Switch in place of the switch - the holes line up with the UK back box threads.

A little bit of automation shenanigans on the M3 and it works beautifully.

Hello, @_Mevi.
For those who have only a phase wire in the box.
If the switch on the wall controls two lamps in one fixture, you can redo the power circuit and feed the neutral wire into the box with the switch.
Existing power circuit

Circuit after change.
Fig. 2

I used this principle for all lamps that were controlled by a double switch. Now the smart switch H2 has zero and phase and is connected to the smart lamp T2M Aqara.

@gafich10

It could work in the hallway. Probably safer if it wasn’t me doing the electrical work.
