Incorrect OTA image for Sonoff MINI-ZBRBS #1272
Description
Recently an OTA started to be available for Sonoff MINI-ZBRBS.
Original firmware version is 1.0.5 (20250711) while the offered one is 1.1.0
The offered one:
{
"installed_version": 4101,
"latest_release_notes": "- Added support for Imperial gallons.\n- Fixed several RTC and battery reporting issues.\n- Improved Bluetooth connection reliability by automatically disconnecting after prolonged inactivity.",
"latest_source": "https://raw.githubusercontent.com/Koenkk/zigbee-OTA/master/images/Sonoff/SN-TLSR8656-SWV1C-01-v1.1.0.ota",
"latest_version": 4352,
"state": "available"
}The file name and release notes look very weird, model in the filename does not seem to match MINI-ZBRBS and release notes do not make sense - e.g. bluetooth, gallons?
Anyway, I tried to update one device to verify but INVALID_IMAGE error is returned:
error: z2m: OTA update of '...' failed (OTA update of 0x... failed with reason: INVALID_IMAGE).

I can independently reproduce this with both device types in the same Zigbee2MQTT installation:
4101(1.0.5), offered version4352(1.1.0)4103(1.0.7), offered version4352(1.1.0)For both devices Zigbee2MQTT selects exactly the same image:
https://raw.githubusercontent.com/Koenkk/zigbee-OTA/master/images/Sonoff/SN-TLSR8656-SWV1C-01-v1.1.0.otaThe release notes about Imperial gallons, RTC/battery reporting and Bluetooth clearly belong to the water valve. I did not start the update on the shutter.
The corresponding index entry has
manufacturerCode: 4742andimageType: 8204, but nomodelIdrestriction. It therefore appears that the valve and the MINI-ZBRBS expose the same OTA manufacturer/image-type combination and the generic OTA matcher selects the valve image for both devices.A possible fix would be to restrict this OTA entry to the SWV-ZFE/SWV-ZFU model IDs (or otherwise add device-specific matching), so it is no longer offered to the MINI-ZBRBS.

Yeah, the filename of the image tells exactly it's SWV1C water valve. I have one test shutter device, so I gave this one a shot and yeah, INVALID_IMAGE says it all.
