The release adds SmartThings Now to the Home tab, introduces a more prominent local-control path, improves offline diagnostics and adds support for Matter 1.6 device categories. Samsung says local control can keep supported devices responsive during external internet disruptions and can reduce response times by about 30% in controlled tests.\n\n ![A smart-home hub, router and lit lamp in a home interior during an internet outage](https://publicasta.com/storage/projects/14/pages/784/2026/10/50293a00-253a-47b4-b542-b8a9e2a19a02.webp)\n\n That is useful, but it is not the same as saying that a SmartThings home is now local-first. A hub, a device, an automation and the phone interface can have different dependencies. A light may still respond through the hub while a cloud service, camera history, notification, voice command or remote control session fails. A routine can also look simple in the app while quietly including one cloud-only device or service that forces the whole rule into the cloud.\n\n The practical question after this update is therefore not “Does SmartThings work offline?” It is “Which actions in my home still work when the internet is unavailable, and how do I know before I need them?”\n\n ## What Samsung changed on October 6\n\n The update has three parts that matter to ordinary households. SmartThings Now places context-sensitive cards at the top of the Home tab. These may suggest controls, surface information or propose a routine based on recent activity and location. Samsung says the feature can suggest actions such as turning on lights or an air purifier when a user approaches home, and can offer routine-management information based on the previous week’s activity.\n\n The second part is the more consequential one: expanded local control. Samsung says that when a mobile device and a compatible SmartThings Hub are connected to the same Wi-Fi network, the phone can communicate directly with the hub instead of routing the control through the cloud. The company lists SmartThings Station, V2, V3 and V4 Hubs, along with hub-enabled Samsung Smart TVs and Family Hub devices, as supported hardware for local control. Availability can still depend on region, software version, device type and the integration used by each product.\n\n The third part is diagnostic and compatibility work. Samsung says the updated Offline Device Diagnostics page can apply new network information across registered devices at once. The release also adds Matter 1.6 support and four device categories: energy meters, closures for specialised doors and gates, irrigation devices and soil sensors. These additions are more relevant to new purchases and future automations than to an immediate outage recovery, but they show where SmartThings is trying to extend local and standards-based control.\n\n Samsung’s announcement is the primary source for the feature list and the supported hub families. It also makes an important qualification: the claimed 30% response-time improvement comes from Samsung’s controlled testing, so it should not be treated as a guarantee for a congested Wi-Fi network, a distant hub or a device with weak radio coverage. [Samsung’s release describes SmartThings Now, local control, supported hubs and Matter 1.6 support](https://news.samsung.com/global/samsung-introduces-smartthings-now-in-new-platform-update-that-brings-more-intuitive-user-experiences).\n\n ## Local control is a chain, not a switch\n\n A smart-home action normally crosses several layers:\n\n - the physical device, such as a bulb, switch, contact sensor, lock or thermostat;\n- the radio or network path, such as Zigbee, Z-Wave, Thread, Wi-Fi or Ethernet;\n- the SmartThings Hub or another controller;\n- the device integration or Edge Driver;\n- the automation logic;\n- the user interface, notification service or voice assistant.\n\n For an action to remain available during an internet outage, every necessary part of that action must have an offline-capable path. If a motion sensor and a Zigbee light are connected to a compatible hub, a basic “motion turns on light” rule may be able to run locally. If the same rule sends a push notification through an online service, asks a cloud weather service for a condition, or controls a cloud-only appliance, it may no longer be fully local.\n\n SmartThings’ developer documentation states the rule clearly: automations run locally on a hub only when all device features and services involved support local execution. If any required feature or service does not support local execution, the rule runs in the SmartThings Cloud. [SmartThings’ rules documentation explains the all-components requirement for local execution](https://developer.smartthings.com/docs/automations/rules).\n\n That distinction is easy to miss because the app presents local and cloud-backed devices in a single interface. A device being visible in the SmartThings app does not prove that its command is local. Nor does the Matter logo prove that every feature, scene or automation using the device will remain available without the internet. Matter provides a local device protocol, but the controller, phone, routine and extra services still determine how the finished experience behaves.\n\n ## Which devices have the best chance of working offline?\n\n The strongest candidates are devices that connect directly to a compatible hub over Zigbee, Z-Wave or Matter, and that are represented by an integration capable of local execution. Basic switches, bulbs, plugs, contact sensors and motion sensors are usually easier to operate locally than products built around a manufacturer’s cloud account. That is a general design pattern, not a guarantee for a particular model. The actual result depends on the driver and capabilities exposed to SmartThings.\n\n SmartThings says its hub-connected Matter, Zigbee and Z-Wave devices use Edge Drivers and run locally on the hub. The developer documentation describes this as a benefit of hub-connected devices, including better reliability and responsiveness. [SmartThings’ hub-connected device documentation explains the role of Edge Drivers and local execution](https://developer.smartthings.com/devices/hub-connected).\n\n There are several reasons not to turn that statement into a blanket promise:\n\n - A device may be connected through a cloud integration rather than a local driver.\n- A single product may expose basic on/off control locally but keep advanced features in the cloud.\n- A routine can include a cloud-only service even when its main devices are local.\n- A hub can remain powered while losing the radio, Wi-Fi or network path required by a particular device.\n- A local command from a phone may require the phone and hub to be on the same local network.\n- Remote access from outside the home still depends on an internet path unless another remote-access system is available.\n\n The most reliable offline functions are therefore usually narrow and predictable: a wall switch controlling a light, a contact sensor triggering a local light, or a temperature threshold adjusting a compatible thermostat through a local rule. The least reliable candidates are functions that need a vendor account, remote video, external speech recognition, online presence data, cloud AI, third-party notifications or a manufacturer’s remote service.\n\n ## Cameras, appliances and locks need separate treatment\n\n The word “device” hides very different failure modes. A light can fail inconveniently; a lock, smoke alarm, appliance shutoff or water valve can fail in a safety-relevant way. Offline testing should reflect that difference.\n\n Cameras are a clear example. A camera may keep recording to local storage while its live view, remote playback, object recognition or push alerts depend on the vendor’s servers. SmartThings’ new Matter 1.6 support does not automatically convert an existing cloud camera into a local camera. The Connectivity Standards Alliance describes Matter as a protocol that can use Wi-Fi, Thread and Ethernet, but the actual device certification and platform implementation still determine which features are available.\n\n Locks require a different caution. A local SmartThings routine that unlocks a door based on presence is not equivalent to a physical key or an independent keypad code. If the hub is unavailable, the phone is dead, the network is segmented or the lock has lost power, the fallback must be clear. Keep the manufacturer’s supported manual method available, and do not make an essential entry route depend on a single automation. Do not disable security protections or attempt unsafe modifications to a lock, alarm or electrical device to force local operation.\n\n Appliances are similarly uneven. A smart washer may expose cycle status through the cloud but offer no useful local control. An air conditioner may support local commands through an infrared bridge while scheduling and remote notifications remain online. A refrigerator or oven can appear in SmartThings because it is a Samsung appliance, yet a particular feature may still rely on Samsung’s account and backend services. Treat local control as a feature to verify for the exact action you care about, not as a property inherited by every function in the product.\n\n For fire, gas, water and electrical safety, connected automation should be supplementary. A smart shutoff or alert can add useful information, but it should not replace a compliant smoke alarm, carbon-monoxide alarm, required protective device, professional installation or a safe manual procedure. Never open mains-powered equipment or alter fixed wiring to make an automation local unless you are qualified to do that work and local rules allow it.\n\n ## A practical offline audit for an existing SmartThings home\n\n You do not need to unplug the whole house at once. Start with a short inventory of the actions that matter during a network interruption. Write down the action in plain language rather than the device brand. “Hall motion turns on hall light” is more useful than “Aeotec sensor routine.”\n\n ### 1. Separate essential actions from conveniences\n\n Create three groups:\n\n - essential: entry, lighting on stairs, leak response, temperature protection and critical alerts;\n- useful: bedtime scenes, occupancy lighting, fan control and energy tracking;\n- optional: media, recommendations, AI summaries, remote camera playback and seasonal suggestions.\n\n This prevents a failed cloud feature from being confused with a failed safety plan. It also makes the test manageable. Test the essential group first and keep a manual fallback for each item.\n\n ### 2. Record the hardware path\n\n For each device, note its protocol, hub, integration and the action used. A Matter-over-Wi-Fi device, a Matter-over-Thread device and a cloud-linked Wi-Fi device may all look similar in the app while depending on different paths. Identify whether the command is expected to reach a hub directly, a local network endpoint or a vendor cloud.\n\n If a product has a bridge, include the bridge in the inventory. A Zigbee bulb connected to a local bridge may be reliable, while a cloud-connected bridge integration may behave differently. The bridge is part of the automation’s dependency chain.\n\n ### 3. Inspect routines for hidden cloud dependencies\n\n Open your most important routines and look for more than the trigger and the final action. Check presence, weather, time-zone or sunrise services, voice assistants, notifications, energy tariffs, camera detections and third-party integrations. Each one can affect whether the rule stays local.\n\n A routine that says “if the door opens after sunset, turn on the porch light and send a notification” may split into a local light action and a cloud notification. If the routine requires the notification service before it completes, the behaviour may differ from what you expect. Build a second, simpler local routine for the physical response when that is appropriate.\n\n ### 4. Test the internet path, not the household power\n\n The safest first test is a controlled internet interruption that leaves the hub and local Wi-Fi powered. Use the router’s supported internet-pause function if it has one, or coordinate with the person responsible for the network. Do not pull plugs from a running appliance, disable a security system without a plan or interrupt power to medical equipment.\n\n Before the test, confirm that you can restore the connection and that another person knows what is happening. Test one action at a time:\n\n - press a local switch and observe the light;\n- trigger a contact or motion sensor;\n- run the relevant routine;\n- check whether the hub reports the event;\n- verify what the phone shows while connected to the home Wi-Fi;\n- separately test what happens from a mobile connection outside the home.\n\n Do not treat a cached screen as proof that a command succeeded. Confirm the physical result. If a lock, valve, heater or other consequential device is involved, use a non-destructive test state and follow the manufacturer’s instructions.\n\n ### 5. Test recovery as well as failure\n\n An automation that works offline but duplicates actions when the cloud returns is not fully reliable. After reconnecting the internet, check for repeated notifications, stale sensor states, delayed scenes and routines that ran twice. Verify that devices reappear with correct state rather than assuming the dashboard is accurate.\n\n Samsung says its updated Offline Device Diagnostics can help apply new network information across registered devices. That can reduce recovery work after a router replacement or network change, but it does not remove the need to check device-specific pairing, Thread credentials, IP reservations or cloud reauthentication.\n\n ## What Matter 1.6 changes for buyers\n\n Samsung’s announcement says the update adds Matter 1.6 and support for energy meters, closures, irrigation devices and soil sensors. Those categories are practical because they connect the smart home to energy, water and physical property rather than only to lights and entertainment.\n\n An energy meter could make household consumption visible to a wider set of platforms. A closure device could describe a gate, garage door or other specialised opening more precisely. Irrigation and soil-sensor support could make watering rules more portable between ecosystems. In each case, the useful question is whether a platform supports the specific device type and the specific automation you want, not merely whether the product carries a Matter badge.\n\n The broader Matter direction is real, but it is still layered. The Connectivity Standards Alliance says Matter does not replace a smart-home platform. It also notes that Matter can bridge devices using other technologies, including Zigbee and Z-Wave, into a Matter ecosystem. Matter-certified devices may therefore improve interoperability without eliminating the need for a hub, bridge or platform-specific features. [The CSA’s Matter FAQ explains transports, bridges, multi-admin setup and the limits of the standard](https://csa-iot.org/all-solutions/matter/matter-faq/).\n\n The CSA’s Matter 1.5 announcement offers useful context for the pace of change. It added cameras, closures, soil sensors and expanded energy-management capabilities, including tariff and energy data. That context matters because a new Matter version can expand what manufacturers are able to certify, while platform support and device firmware still arrive on their own schedules. [The Connectivity Standards Alliance describes the device categories and energy features added in Matter 1.5](https://csa-iot.org/newsroom/matter-1-5-introduces-cameras-closures-and-enhanced-energy-management-capabilities/).\n\n For a purchase today, buy for a verified path rather than a version number. Check the exact model, transport, required hub, supported Matter device type, local features, firmware policy and what remains available in the manufacturer’s app. If you need local operation, look for explicit local or hub-connected documentation and plan to test it after installation.\n\n ## What SmartThings Now does not solve\n\n The update does not make every SmartThings routine local. SmartThings’ own documentation says that one unsupported feature or service can move a rule to the cloud. It does not make remote control from another city local. It does not guarantee that cloud-based voice assistants, cameras, notifications or AI features work during an outage. It does not turn every Wi-Fi product into a hub-connected product.\n\n It also does not resolve the difference between local control and local privacy. A command can travel directly from a phone to a hub while account data, diagnostics, firmware distribution, usage history or other services still involve the cloud. If privacy is part of your buying decision, read the manufacturer’s data and account documentation separately from its offline-control claims.\n\n SmartThings Now may also increase the number of suggestions and contextual cards presented to a household. That can be useful, but suggestions are not the same as a stable automation. Review proposed routines before enabling them, especially if they use location, care information, occupancy signals or appliance activity. Remove routines that duplicate older rules. Samsung says Routine Insight can show recent routine activity and help users review or delete routines, which is a good reason to inspect the list after the update rather than accepting every recommendation.\n\n ## The sensible response to the update\n\n If you already use SmartThings, install the update when it reaches your devices, then audit the actions you would miss during an outage. Start with a light, switch or sensor routine, not with a lock, heater or appliance shutoff. Confirm the hub model, update firmware, inspect the routine’s dependencies and test while local Wi-Fi remains available.\n\n If a critical action is cloud-only, decide whether the right answer is a local-capable device, a different integration, a bridge, a simpler routine or a manual fallback. Replacing everything is rarely necessary. In many homes, the practical improvement comes from moving a few high-value actions onto a local path and leaving optional cloud features where they are useful.\n\n For a new purchase, treat “works with SmartThings,” “Matter,” “local control” and “works without internet” as four different claims. Verify each one for the model and the action. A device can satisfy the first two and fail the last two.\n\n SmartThings Now is a meaningful reliability update because it makes local control more visible and adds diagnostic help at the moment users are likely to need it. Its real value will be measured by the boring actions: whether a switch responds, whether a sensor still triggers a light, whether a routine avoids duplicate actions after recovery and whether the household knows what to do when the app cannot reach the cloud. That is the test worth running this week.","available_translations":[{"language":"ar","title":"يضيف SmartThings الآن تحكماً محلياً: ما الذي يستمر عند انقطاع
