Yes—this can happen because the Lockin Smart App and Matter are separate control paths. On the Lockin Veno Solar Palm, the app’s remote controls use the lock’s native Wi‑Fi connection, while Matter over Thread reaches the lock through a compatible Matter controller and Thread border router. A router replacement can leave those paths in different states.
If Matter still locks and unlocks the door, preserve that working pairing. First reconnect the lock to the new 2.4 GHz Wi‑Fi network in the Lockin Smart App instead of deleting the Matter accessory or factory-resetting the lock.
The short diagnosis
| What still works | What it usually tells you | First action |
|---|---|---|
| Palm, PIN, or key entry works; Matter works; the Lockin app does not | The lock is operating, but its native Wi‑Fi path may still contain the old router details | Switch the lock to the new Wi‑Fi network in the app |
| Palm, PIN, or key entry works; the app works; Matter does not | The native Wi‑Fi path is available, but the Matter controller, Thread border router, or local network path needs attention | Check the controller’s network and Matter status |
| Local entry works; both app and Matter fail | The lock may be fine while the new router, controller, or credentials are not | Restore network paths one at a time; do not reset first |
| Local entry also fails | This is not only a router-path problem | Check power, the door, and a backup entry method before network changes |
Matter working does not prove that the old Wi‑Fi settings are still correct. It only shows that the Matter route is currently reachable enough for the supported command you tested.
Why the two paths can disagree
The Veno Solar Palm has built-in Wi‑Fi for app management and Matter over Thread for smart-home integration. Lockin describes the app as the full setup, settings, and management surface. Its documentation also separates Matter’s cross-platform controls from app functions such as temporary codes, access logs, firmware updates, battery settings, and biometric management.
Thread is a low-power mesh network. A Thread border router connects that mesh to the household local network used by the Matter controller. The router you replaced may have been the Wi‑Fi or Ethernet connection for that border router, but that does not automatically mean the lock’s Thread credentials or Matter fabric were erased. Conversely, it is unsafe to assume that Thread stayed unchanged: a controller may be offline, on a different LAN, or unable to pass the local discovery traffic Matter needs.
The useful distinction is therefore:
- Native Wi‑Fi path: Lockin Smart App to the lock’s configured 2.4 GHz Wi‑Fi connection and Lockin services.
- Matter path: Matter controller to a Thread border router and the commissioned Matter/Thread network.
- Local entry path: palm-vein recognition, PIN, or mechanical key at the door.
These paths can fail independently after a router change.
Reconnect the Veno Solar Palm to the new Wi‑Fi
Do this while you still have a working local entry method and, if possible, a working Matter control path.
- Put the new router’s 2.4 GHz network within reliable range of the lock. The current Veno Solar Palm FAQ says the lock connects to 2.4 GHz Wi‑Fi, not 5 GHz. Keep the SSID visible and use the documented WPA or WPA2 security options while troubleshooting.
- Connect your phone to that 2.4 GHz network and open the Lockin Smart App.
- Open Devices, select the Veno Solar Palm, then open Settings → Device Information → WiFi.
- Check the current Wi‑Fi status and use the option to switch networks.
- Enter the new network details and wait for the app to report the connection.
- Test native app locking, unlocking, and one non-destructive status view. Then test the Matter controller separately.
The exact menu is important. A router replacement does not require you to remove a functioning Matter accessory just to change the lock’s native Wi‑Fi details.
If the new router combines bands under one network name, temporarily use a clearly available 2.4 GHz SSID while diagnosing. Do not treat a successful phone connection on 5 GHz as proof that the lock can use that band—the Veno Solar Palm FAQ says it cannot.
Keep the working Matter pairing intact
If Matter still responds, do not unpair, delete, or recommission the lock as a first step. Record which Matter app and controller worked, and whether you tested both lock and unlock. Then check the infrastructure around it:
- Confirm the Matter controller or Thread border router is powered on and connected to the new router.
- Confirm it is on the household LAN you intend to use, not an isolated guest network.
- If the router created new VLANs or enabled client isolation, check whether local IPv6, mDNS, and multicast traffic can pass between the controller and the rest of the Matter network. Matter troubleshooting guidance commonly identifies those local discovery paths as dependencies.
- Open the Matter app and refresh the accessory state. Test a lock command, then verify the physical deadbolt state at the door.
- If the controller reports the accessory as unavailable, restore the controller’s network connection before touching the lock’s pairing.
Do not weaken the entire home network as a shortcut. Use the router and controller documentation to make only the narrowly required local-network change, then retest.
What Matter will not replace in the Lockin app
Matter can keep basic cross-platform lock control available, but it is not a copy of the Lockin Smart App. Depending on the ecosystem and model support, Matter may expose lock controls, voice control, sharing, or automations. The Lockin documentation reserves deeper device management for the app.
| Need | Use the path that documents it |
|---|---|
| Lock or unlock from a supported smart-home app | Matter controller, if the accessory is reachable |
| Change the lock’s native Wi‑Fi network | Lockin Smart App → Device Information → WiFi |
| Manage palm-vein profiles or other device settings | Lockin Smart App |
| Create temporary or recurring access codes | Lockin Smart App |
| Review Lockin access events or manage firmware | Lockin Smart App |
| Enter at the door during a network problem | Palm vein, PIN, or mechanical key, subject to the lock’s state and your setup |
That is why “Matter still works” and “the app cannot connect” can both be true without either app having changed the other path.
When to investigate the router more deeply
Use the symptom pattern rather than changing several settings at once.
If switching the lock to the new 2.4 GHz network restores the Lockin app but Matter stops responding, inspect the Matter controller and Thread border router connection to the new LAN. The lock’s native Wi‑Fi repair did not necessarily repair the controller’s local route.
If the app works but Matter does not, inspect local IPv6 and discovery conditions, controller status, Thread-network credentials, and VLAN or guest-network isolation. Matter’s local path is not the same as a cloud app login.
If neither remote path works but palm or PIN entry works, keep the door usable and continue with network diagnosis. If local entry does not work, stop remote experimentation and use the physical key or the manufacturer’s support route as appropriate.
Avoid a premature factory reset
A factory reset is not the normal first response to a changed router. The current Lockin FAQ warns that resetting erases data, and its Wi‑Fi troubleshooting sequence places reset after checking the 2.4 GHz network, charging, a temporary hotspot test, and hardware connections.
Before considering a reset:
- Keep the mechanical key accessible.
- Confirm that the lock has adequate power.
- Write down the current Matter controller, home, and accessory names.
- Make sure you can recreate authorized access after a reset.
- Check the current model manual and Lockin support instructions for the reset sequence.
Reset only when the model-specific support procedure calls for it and you are prepared to rebuild the affected access paths. Do not assume a reset will preserve the Matter pairing.
Final test after the router change
Run this small test and record the result for each path:
- Unlock locally with palm vein or PIN.
- Lock locally and confirm the deadbolt physically moved.
- Lock and unlock from the Lockin Smart App after switching its Wi‑Fi network.
- Lock and unlock from the Matter controller.
- Check one app-only function, such as the Wi‑Fi status or a settings page.
- Keep the mechanical key available until all required paths pass.
For the Lockin Veno Solar Palm, the safest interpretation is not “the new router left Matter untouched.” It is: the native Wi‑Fi path and the Matter-over-Thread path must be tested and repaired independently. Reconnect the app’s Wi‑Fi path through Device Information, preserve any functioning Matter pairing, and only escalate to controller or factory-reset work when the symptom pattern identifies that layer.
For model details, see the Veno Solar Palm product page, Lockin FAQ, and Lockin user manual library. If the Matter accessory is paired but unreachable after the network checks, continue with Matter smart lock paired but not responding: check local IPv6 support.
