SNZB-02D doing OTA checks every 5mins

MFornander commented 1 week ago

What happened?

Looking at the logs I see that the otherwise awesome SONOFF SNZB-02D T&H w/ display, does an OTA check (genOta commandQueryNextImageRequest) every 5mins which will really drain the battery since the other updates are set to very infrequent.

Now I realize that this is probably not zigbee2mqtt's fault since it responds with a "NO_IMAGE_AVAILABLE" (genOta queryNextImageResponse) but I'm wondering if the reply payload doesn't satisfy the SNZB-02D so it keeps trying.

Is anyone else seeing this and/or working on a solution? I'm about to order a SONOFF Zigbee Bridge Pro Hub and boot up my Zigbee sniffer to figure this out. I'm wondering if there is a response or arcane set of commands that quiet the chatter if paired with a standard SONOFF controller.

Any ideas or workarounds? Is everyone else's SNZB-02D reporting softwareBuildID: 1.0.9 and maybe I have an old firmware?

SNZB-02D device state below:

{
    "battery": 100,
    "humidity": 54.4,
    "last_seen": "2024-06-25T04:47:56.030Z",

        "type": "EndDevice",
        "zclVersion": 8
    }
}

What did you expect to happen?

I expected that OTA checks would be at most every day.

How to reproduce it (minimal and precise)

Install zigbee2mqtt
add SNZB-02D
Enable z2m debug log
See "z2m: Device 'SNZB-02D' requested OTA" every 5mins

I'm seeing the same on my SONOFF SNZB-02D also on firmware 1.0.9. I hadn't noticed but your issue made me check my logs. Edit: no adverse effects on battery level here, still 100% after approx. 6 months.

Hijacking my own issue to let people know I'm working on a more complete z2m driver for SNZB-02D.

After some zniffing between it and a ZBBridge using eWeLink, I'm seeing attribute conversations that allows you to set high/low temp, high/low humidity, and temperature unit (using ZB not double click). It also looks like the button in the back sends an on/off event which could be exposed, and I'm seeing a sun icon when it's bright so maybe it even has a light sensor with events. Nice little $12 device if so!

I reached out to SONOFF support about the OTA issue and actually got an initial reply asking for more details. It looks like the 1.0.9 version is the latest according to eWeLink so no firmware patch for it yet.

@MFornander Great find! Let me know if you need any help with a modernExtend converter. 😊
