Describe the bug

I have a mix of T8410 and T8410Cs, since the last update the camera enabled switch (switch.porch_camera_enabled) doesn't work on any of them anymore.

If I drill into the device the toggle is always disabled, despite the camera being on. When I switch it on, it stays on before for a few seconds flipping back to off. If I go to the dev tools and switch the state there, the GUI representation of the switch will show on and stay on, but switching it off again there or back in the device does nothing.

All other functions work; arming, PTZ, enabling stream - it's literally just the "enabled" control on all of them. I noticed my automations making announcements that they shouldn't have been for a few weeks now and didn't think anything of it until I decided to sit down and figure out what was going on when it happened again today.

T8410C firmware: 3.3.3.2
T8410 firmware: 2.3.1.6

No HomeBases, just straight wifi cameras.

I've tried refreshing my credentials (even switched them to the master account rather than a shared account) but have stopped short of deleting the integration and starting over.

I have attached debug log, hopefully it helps. I tried toggling the offending switches a few times, and hit some PTZ and changed controls on one of the cameras while I was logging.

This looks particularly interesting:

2026-01-09 09:19:27.282 DEBUG (MainThread) [custom_components.eufy_security.eufy_security_api] _on_message - {'type': 'event', 'event': {'source': 'device', 'event': 'command result', 'serialNumber': 'T8410########', 'command': 'set_property', 'returnCode': -103, 'returnCodeName': 'ERROR_INVALID_COMMAND', 'customData': {'property': {'name': 'enabled', 'value': True}}}}

To reproduce

1. Go to 'Settings/Devices/Services/Eufy Security'
2. Click on 'any T8410(C) camera, then toggle the switch "Camera Enabled" in controls (i.e. 'switch.garage_camera_enabled' entity')
3. Watch the switch toggle and toggle back without affecting the camera

I've confirmed release 1.9.9.resolves this issue. All of my switches are working again.

Thank you very much.
