Does the Wyze Cam v3 work without internet?
Not out of the box. The Wyze Cam v3 phones home to Wyze as sold. Flash it with Thingino or custom and it stops, for good.
Verdict · as sold
Local after flashingPhones home as sold. New firmware stops that, warranty not included.
Flashable. Put Thingino or custom on it and it becomes fully local. Details below.

Seven questions, as sold.
6 of 7 checked. Every yes or no links to its source and the date it was checked. Nothing here assumes a flash: that’s the next section.
- Works with the internet cut 01 · No
Does the main function survive with the WAN cable pulled?
Wyze states that offline the camera "can only record to a microSD card"; live view, motion and sound detection, notifications and settings all require the connection, and the app cannot reach the camera on the LAN.
- No vendor account needed 02 · No
Can it be set up without creating an account with the manufacturer?
Setup is done in the Wyze app after "Create a Wyze account, and/or sign in".
- Documented local API 03 · No
Is there a publicly documented local protocol: HTTP, MQTT, ONVIF, RTSP, Zigbee, Z-Wave, Matter, Modbus?
Stock firmware has no RTSP; it required a separate beta firmware flashed from microSD, and Wyze says it has "removed the firmware files for these versions for now".
- Can be firewalled off for good 04 · No
Can it be cut off from the internet permanently without anything breaking?
Blocked from Wyze's servers the camera only writes to its microSD card; it cannot be viewed or configured until it reconnects.
- Firmware updates without the cloud 05 · Yes
Can it be updated by hand, with no forced auto-update?
Wyze documents manual flashing of the v3 from a microSD card, and Automatic Update can be toggled off in the app (support.wyze.com).
- Runs alternative firmware 06 · Yes
Can it run ESPHome, Tasmota, OpenBeken, Valetudo or OpenIPC?
Listed as "Wyze Cam v3" on the Thingino supported hardware list (T31X SoC).
- Home Assistant talks to it locally 07 · Not checked
Is the Home Assistant integration local_push or local_polling?
Already own one? Into Home Assistant, then.
A different question from the verdict. Home Assistant can talk to a device locally and still need Wyze’s servers to get started, or for good. This is what the integration itself needs.
Not as sold. Put Thingino or custom on the Wyze Cam v3 and Home Assistant talks to it directly, with Wyze out of the loop.

No core integration and no local protocol on stock firmware. After flashing Thingino the camera speaks ONVIF/RTSP and the core ONVIF integration (Local Push) needs no vendor at all. Without flashing, the docker-wyze-bridge Home Assistant add-on (github.com) turns the cameras into local RTSP/WebRTC streams but needs a Wyze login plus an API key, and its README warns streams will probably stop after some time without the cloud.
The way out: new firmware.

The Thingino installer is written to a microSD card, backs up the stock firmware (combined_backup.bin) on first boot and documents how to restore it. The other route is wz_mini_hacks (github.com), which stays on stock firmware and adds RTSP via go2rtc from the card, but its RTSP only works on firmware up to 4.36.9.139 (github.com).
Flashing voids the warranty and can brick the device. Read the whole guide before starting.
Question 08 · the company
Wyze’s track record.
This company has taken local control away from devices people already owned. Each incident below links to its source.
- Wyze pulled the RTSP firmware downloads for Wyze Cam v2, v3 and Pan, the only local-stream option for those cameras, saying RTSP "was considered a beta feature" and that the files were removed while it assessed the path forward. Cameras already flashed kept running the old build, but owners had no supported way to get or keep local streaming. Source
Editor’s note
In plain words.
As sold, the Cam v3 is blind without Wyze: it keeps writing to its microSD card, but you cannot watch it, get alerts or change a setting until it talks to Wyze's servers again, and the official RTSP firmware has been pulled. The way out is real and cheap: a microSD card with Thingino turns it into a plain ONVIF/RTSP camera with no account, and the installer keeps a backup so you can go back. Turn off Automatic Update first if you plan to use wz_mini_hacks, which needs older firmware.
Wrong? Probably somewhere.
Say where. A link and a sentence is enough. Every claim above carries its source so it can be checked.
