Hi!
I am looking for a nice way to update the firmware of my sonoff devices (motion sensors + zbmini-l). How are you guys doing that?
I am using ZHA with a conbee stick so far, which doesnt support OTA updates for sonoff devices.
@davidaichi I use a Sonoff Zigbee Stick with Z2M and also I have paired my Sonoff devices (plugs and ZBMINIs) to the Sonoff Zigbee Bridge with the EweLink app and I can see no way to update the devices. @Koenkk has mentioned previously that Sonoff have not released any OTA links for Z2M

FYI, this is still the case, and what more, ITead has not yet released any Zigbee OTA firmware image updates for any Zigbee Router or Zigbee End-Device products/devices at all, not even through their own Sonoff ZBBridge Gateway. See related this somewhat discussion → https://github.com/Koenkk/zigbee2mqtt/issues/10282
FYI, ITead has released OTA firmware for Sonoff ZBMINI-L that is meant to address delay issues:
https://github.com/Koenkk/zigbee-OTA/tree/master/images/Sonoff
https://github.com/zigpy/zha-device-handlers/issues/1519
You can flash these with ZHA if enable OTA and then manually copy the OTA file(s) to correct directory:
https://www.home-assistant.io/integrations/zha#ota-firmware-updates
https://github.com/zigpy/zigpy/wiki/OTA-Device-Firmware-Updates
I’ve not read about any ZHA/zigpy developers working on adding OTA provider to zigpy for sonoff, see:
https://github.com/zigpy/zigpy/issues/987
https://github.com/zigpy/zigpy/issues/535
https://github.com/zigpy/zigpy/tree/dev/zigpy/ota
zigpy developers prefer manufacturers or independent developers to contribute PR with download code:
https://github.com/zigpy/zigpy#zigbee-device-ota-updates
If you are using Zigbee2MQTT then need to copy Zigee OTA image files manually as well as no OTA provider for ITead/Sonoff is yet in zigbee-herdsman-converters:
https://github.com/Koenkk/zigbee-herdsman-converters/tree/master/lib/ota
https://www.zigbee2mqtt.io/guide/usage/ota_updates.html
PS: Off-topic, FYI, recommendation is also to disable “permit join” in Zigbee2MQTT due to both security reason as well as a memory leak issue found in some Zigbee Router firmware for ITead Sonoff devices.

I see that the S40ZB Lite has a firmware as well in Koenkk’s repo.
It would be great if the original ZBMINI would receive some love as well, in a form of an updated firmware.
Note! There are also old hardware revisions/variants of Sonoff ZBMINI based on older CC2530 chip and newer hardware revisions/variants of Sonoff ZBMINI based on the newer CC2652 chips.
I don’t think the old or new hardware revisions/variants support Zigbee OTA in their original firmware(?).
FYI, PVTO has built unofficial (third-party) custom firmware for the newer revisions of ITead’s Sonoff ZBMINI (01MINIZB) and eWeLink Switch ZR-02 based on CC2652P (CC2652P1F) chip. The main disadvantage: you need the cJTAG-compatible flasher debugger probe adapter (XDS110 or J-Link V11) in order to flash as the original firmware does not have a serial bootloader. see → https://ptvo.info/custom-firmware-for-sonoff-zbmini-01minizb-and-ewelink-switch-zr-02-923/

I am not that desperate at the moment to rip it out from behind the wall switch. But I am sad to read that the functionality is missing.
Otherwise, I have no idea is it the older or newer revision. Probably the older, because I have it for a few years.
Then you are out of luck. Regardless, suggest send OTA feature request to Sonoff for future products.

FYI, victorigualada wrote a step-by-step guide in the Home Assistant community forum on all the elaborated steps currently needed for an end-user to manually apply a custom Zigbee OTA firmware image to a device in the ZHA integration if there is not an OTA provider in zigpy:
