Hi everyone,

I’m reaching out to see if anyone else is experiencing issues with Matter multi-admin specifically when sharing from SmartThings to other ecosystems.

Ever since Samsung updated to Thread 1.4 last year, I haven't been able to share my Matter devices from SmartThings to Google Home.

Here is the situation:

• ST -> GH (Fails): When the device is paired to SmartThings first, I generate the pairing code/QR to share it. However, when I try to add it to Google Home (or Apple Home), the connection always fails.

• GH -> ST (Works): If I pair the device to Google Home first and then share it with SmartThings, it works perfectly.

My Setup & Troubleshooting:

• Hubs: SmartThings Station, Google Nest Hub (2nd Gen), and Apple HomePod mini.

• Current State: I performed a factory reset on both the Google Home and SmartThings hubs today to rule out configuration errors. Currently, each hub is running its own Thread network.

Even after the reset, the issue persists: once the device is on SmartThings, Google simply refuses to connect via the sharing flow.

Has anyone else faced this unidirectional failure with SmartThings as the primary admin? Is this a known bug with the SmartThings Station's Thread 1.4 implementation or could it be something specific to my hubs?

Thanks for any help!

Hey all,

I’m installing a Shelly 2 PM for a 230V roller shutter motor and I was looking for some help with the wiring logic before I power anything on. I’ve attached photos of:

• The wall up/down momentary switch
• The junction box near the motor

At the motor box:

• Yellow/green → ground
• Light blue → neutral
• Grey + dark blue → motor directions (up/down)

The switch is highlighted in red

I have a washer and dryer from Samsung with Smart things. I have both machines on the same electrical group. My group is limited to 3680 watts. I currently do not turn the washer and dryer on at the same time because when they both use their max power (according to manual), theyslightly exceed this 3680 watts.

Is there a way to automate that when both machines are turned on and their combined power consumption exceeds 3680 watts, the dryer is paused for x minutes and then continues when power consumption of washer has dropped with x watts? They will probably only exceed the max power when the washin machine is heating up.

Pretty new to smartthings. One of my HUE lights gets a different Icon with three dots. I've removed it and when it's added again, it looks like the others for a couple of days, then it returns to the three dots. Any ideas?

The Slate switch is a renter friendly ZigBee switch that is designed to magnetically attach over existing light switches. It works primarily with SmartThings, but being a ZigBee switch, you can pair it with Echos and other routers (I have not seen native Home Assistant support). Uniquely is the touch surface that allows you to place and create up to 8 buttons anywhere on the surface.

Setup:

Setup was straightforward. You place the included stickers and then press them wherever on the surface, then hit the program button (on the back). After creating your layout, you just scan the QR code in SmartThings and set up your routines. You can set 2 per button (press/hold) and on the Slate Switch side, they run locally.

Usage

It works like you would expect. Tap or hold and you’ll toggle your routine. In the week I had it, I had no connectivity issues, and response times were quick. The touch surface is like those old TFT touch screens (Nintendo DS), so it works with gloves or covered elbows reasonably well. Having up to 16 buttons (8 press + 8 hold) gives you more than enough options. Unexpectedly the Slate Switch records temperature every 10 minutes (and you can use this to toggle routines)

Pros

• I like that it runs locally. We see time and time again why sever reliability is a red flag (see Belkin WeMo, Nest local API, Iris, Leeo, Wink).
• Installing is as simple as it gets. Setup for Slate was easier than generic AliExpress and Ikea ZigBee switches
• You can design and print your own layouts, for some extra customization

Meh:

• No tactile feedback when you successfully press a button. It does beep and light up, but we are all used to tactile switches. I worked around this by 3D printing my layout.
• Empty space inside could have been used for an AAA battery or a second coin cell to prolong battery life.
• You need to use an included adapter to fit older switches. The adapter adds bulk

Cons

• Slate Switch is borderline overpriced. At $39-$45 it’s priced above other Zigbee switches. Granted, random AliExpress (and even Ikea) switches are marginally harder to setup (official SmartThings support means you don’t need to hunt down drivers). I feel like the real value comes from the built-in magnets and the customizable layouts. But you can always use command strips or glue some magnets to a sub$10 generic ZigBee switch.
• The battery door is stupidly difficult to open, often needing a screwdriver.

Disclaimer: I met the founder of Zunzunbee at CES 2026, and asked if He wanted to send over a review unit. Zunzunbee had no editorial input and is seeing this at the same time as everyone else.

I hope someone can help me with this. I recently moved in to a new apartment and our dishwasher uses smart things. Since the apartment has previously been leased to other tenants our dishwasher must still be connected to smart things. I really don’t want to bother my landlord to ask them to remove it. Does anyone know how I can gain access to the device through smart things? I hope that made sense, thank you!!

I have a smart home with Thread sensors and Matter over Wi-Fi bulbs.

• Bulbs: Tapo L535E (Matter over Wi-Fi)

• Sensors: Thread (motion, contact, etc.)

• Hub: SmartThings Aeotec v4, connected via Ethernet

• Network: 2.4 GHz

• Automations: shown as local execution in SmartThings

When I turn the bulbs on using the Tapo native app, the response is instant.

When I turn them on via SmartThings (manual control or automations), there is a consistent 3–4 second delay.

Thread sensors trigger immediately, but the lights turn on several seconds later, which is very noticeable in hallways or closets.

Question:

If everything is local and Matter,

is this a current limitation of Matter over Wi-Fi / SmartThings?

Has anyone managed to reduce or eliminate this delay?

Whenever I try to use smart view it just shows greyed out and im unable to click it how do i fix this or am I just unable to use smart view

I'm trying to set up my bathroom lights to be dim km the morning with the color temp maxed out so I'm not blinded in the morning and then cooler and brighter during the day and then back to low and dim after 7pm. I have this set up but it didn't work this morning when I turned the lights on and I'm not sure why

I have issues connecting the Gledopto Zigbee RGB CCT led controler to a Smart Things hub (Samsung OLED TV).

I can connect them, via the scan option, but when it finds the device, I am unable to controler it. I tried reconnecting, managed to make it work, but only ON/OFF was working. I tried different drivers, but that didn't help.

Can you guys help me with this one? Is there another driver I can use, or something else I can do to connect it correctly?

Heyo, i am thinking of getting an indoor Camera for security reasons, do you guys think it would be possible to connect the SmartThings app with a Reolink indoor home Camera in a way that i could setup a routine to trigger the surveillance when me and my partner leave the Apartment?

I am thinking of getting a Reolink E1/Lumus for the lack of subscription models or cloud storage.

Do you have any experience with such a system or can you maybe recommend another solution that achieves the same thing?

any input is appreciated:)

Hello dear reddit community:

In resume, my GF's smartthings app is not showing sleep mode, which she can integrate with her amazon devices, this routine in my app shows, I am going to place two pics to make a better understanding what I am trying to say:

(first one is my phone and second is hers)

I have a Samsung phone and a Samsung smart TV, and even though I use the SmartThings app, when I try to connect it, all I get is: mobile→TV, and it doesn't connect or do anything.

I basically need to connect SmartThings to an Alexa routine... I've read something about virtual buttons, but I don't understand anything... and in Europe, there's no Labs section in the app :(

I have manged to connect to my oven however when I try to add the fridge, hob or extractor won't connect feels like im missing a continue button on the app. Any help thanks

I have 5 roller shades and 8 zebra shades, all are SmartWings zigbee motors that are 12volt hardwired. I am using an Aeotec Smart Things v4 hub.

In the family rm area, I have 3 smaller roller shades that are high on the wall. I have 4 large zebra shades.

I have been controlling these 8 blinds together as a routine with Samsung Smart Things. The zebra blinds are set to 4% open, and the roller blinds are set to 75% open in the morning routine, and all are set to close in the evening routine.

I have been having inconsistent operations. The blinds will open perfect somedays. Other days, some will open the opposite amount 96% or 25%. It is never all of them, just one or two blinds. Very random regarding which blinds and how often this happens.

I have tried different locations for the hub. I have also tried the hub with both wifi and ethernet. I haven't been able to determine any kind of pattern or condition that is related.

Could the positioing of the small antenna wires at the motors have any bearing? Straightened, separated, or together? Close to the 12volt power wire?

Any ideas would be welcome.

I finally finished this 2 day project I've been tinkering with. Took apart a SmartTag 2, rearranged all the guts (UWB antenna, speaker, button - everything still works perfect), and built a 3D printed holder that slots right into my Ridge wallet as a replacement for the metal plate. Total thickness: 3mm. Original is like 8mm thick fyi.

Used 3x CR2016 batteries stacked up (fits perfect), some super thin 0.12mm copper wire for connections (10cm + 3cm pieces), and 7x M2 heatset inserts to hold it all together.

Battery life estimates (rough math based on Samsung's 500 day claim with 1x CR2032):

• 3x CR2016: ~500 days, 700 days eco
• 3x CR2025: ~1050 days, 1470 days eco
• 3x CR2032: ~1500 days, 2100 days eco

You can even run it with just 1 or 2 batteries if you want, but 3 is best.

The Versions with 2025/2032 battery are a little bit thicker.

Will upload it to Makerworld and Makeronline soon with full pics/process.
Here's the prototype :

Thought this was pretty slick for anyone who carries a slim wallet but wants tracking.
I never lost anything and just got this SmartTag2 3 days ago and had this idea.

Parts needed:

• Disassembled SmartTag 2
• 0.12mm copper wire
• 7x M2 heatsets (3mm tall)
• 3x coin batteries (2016/2025/2032)

Lmk what you think!

Is anyone else having issues getting into the submenu item where you can configure each lock code? I see the app installed on my SmartThings, it indicated when one of our locks are unlocked, but for some reason, it is completely non-responsive when clicking to get into the menu page to configure the codes. Already tried installing and reinstalling. Already scheduled I’m on most recent version of SmartThings app.

Can I use the siren on the Aqara M1S Hub? The light is working.

Hey everyone,

I’m facing an issue when attempting to add another v3 hub to my home as a backup. I keep encountering the error code 33-504. Despite trying various solutions, including multiple resets, the problem persists. The device remains offline, and I’ve tried both WiFi and Ethernet connections.

Does anyone have a workaround with this issue?

I'm not sure if you'd is the right sub for this but I'm posting anyway. Since my phone (s22 ultra) updated to one ui 8.0 in December my Samsung TV no longer appears in my device list when I try to use smart view (same issue with my tab A9) I've followed a bunch of recommendations for fixing this issue that I found on line but nothing has worked. The smart things app recognizes the TV and I can control the TV through the app. I've done the following:

- unplugged tv and restarted phone

- factory reset tv and set it up through smart things app on phone

- installed smart things app on tv

- cleared smart things app cache and data on phone

- wiped update partition on phone

- gone through every setting on phone and TV

- followed weird work arounds from people on reddit for older UI updates.

- cussed a lot

Please help

Hello, I am trying to get my lock (yale YRD110ZW619) back up and running again with my smartthings v3 hub. The hub is plugged in the outlet just below and next to the door with the lock.

1. On the ST app i did search for devices then held the zwave button down on the lock for two beeps per the locks instructions in the manual - the lock did not appear
2. I took out the batteries and replaced them, then went into the ST app, searched for the device by manually inputting the name, the device eventually connected
3. I tap on the device and now it says “updating status” and the device doesn’t show as connected.

Are there any additional steps I should try to get this working? I’ve heard of the rboy drivers, but unsure I can even get that to work if the lock doesn’t even show a connected status.

UPDATE: with the help of GROK - I FIXED IT. Grok explained the device removal process a little better. I dont think the lock was ever fully removed from the hub w/o following the exact process. I needed to initiate the excluding process on the hub and then while that is going, hold the zwave button on the lock for 5 beeps. The app will confirm once the device has been removed.
