I’ve just got one of these and installed it on my bathroom lights. I only use the attached switch to turn it on/off (no automations sets up etc.) but twice now I’ve had the lights randomly turn themselves off after I’ve turned them on ( between 2-15mins after they’ve been switched on)
Has anyone else experienced this?
I’m also experiencing this problem. You refer to /core and to report it there. I assume someone already created an issue for it that we can use but i cannot seem to find it. I’ll be happy to create it if it doesn’t exist but don’t want to create duplicates.
Anyways, besides the delay problem, after a certain amount of time (couple of weeks) the switch becomes unresponsive. Even when operating it manually. After unplugging the lightbulb and plugging it back in, the switch comes back to life. Is there anyone else with similar experiences?
Also, my SNZB becomes unavailable since a couple of days after a month of working without any isues. Taking out the battery and putting it back in solves it for a couple of hours, then becomes unavailable again.
I have several other Zigbee devices which work flawless and i therefore assume my Zigbee network is fine.
ZBMINI-L @230V / SNZB (03) / ZHA / SONOFF ZigBee 3.0 USB Dongle Plus (Z-Stack 3.30+ (build 20211217))
Be sure to also submit tickets to ITead/Sonoff as the manufacturer as well so they can keep statistics:
https://itead.freshdesk.com/support/home
Based on history they had a tendency to not react to reports of clear firmware bugs until enough people have reported the same problem, even if some in community show how to replicate issue to prove fault.
Again for reference also see Zigbe2MQTT → https://github.com/Koenkk/zigbee2mqtt/issues/11676
Did anyone managed to add a ZBMINI-L to Deconz? I ordered two ZBMINI-L’s but I’m not able to add them in Deconz…
I installed one for my living room lights - I’m experiencing the lights sometimes turning on and off a load of times… no automations in place yet (confirmed via logbooks as well etc).
I might return and go for the ZBMINI now that I’ve figured out how to grab a neutral at the fielding rose (and also discovered ikeas amazing huge light fittings!!)
FYI, zigbee-herdsman developer Koenkk has implemented a Zigbee converter workaround for sonoff devices (like ITead’s Zigbee End-Device such as Sonoff ZBMINI-L) in zigbee-herdsman-converters that should at least solve the slow polling issue which causes delay issues in Zigbee2MQTT (and IoBroker).
Looks like workaround chosen now is to unbind genPollCtrl to prevent the device from sending checkin message which causes Sonoff Zigbee End-Devices poll slower about 1-hour after powering the device.
The fix is available in the very latest dev branch of Zigbee2MQTT and does require you to repair the Sonoff ZBMINI-L device (after updating to latest Zigbee2MQTT dev, a.k.a. Zigbee “edge” version).
https://github.com/Koenkk/zigbee-herdsman-converters/commit/ac7a095463c8b4dec3d6a6b34eb1e221a0f37d90
If can work around this slow delay problem in a Zigbee converter for zigbee-herdsman-converters then maybe it is also possible to do the same in a “quirk” for ZHA Device Handler for the ZHA integration?
See ZHA docs https://www.home-assistant.io/integrations/zha#zha-exception-and-deviation-handling
Anyway, users of the ZHA integration in Home Assistant that have similar delay problems with ZBMINI-L probably want to report this to zha-quirks → https://github.com/zigpy/zha-device-handlers/issues
“New issue” → “Device support request” → Provide Zigbee Device Signature + problem description.
I can confirm that with ZHA the delays are present to. I reported it:
FYI, ITead have just release a new firmware for Sonoff ZBMINI-L that is meant to address delay issues:

We have raised the pull request for the OTA update image on github Pull requests · Koenkk/zigbee-OTA · GitHub.
Once it is approved, you can download the image and update the ZBMINI-L devices.

Feature: Added Poll Control Cluster private attribute 0xFF00 (enable/disable configuration), the default Poll Control Cluster initial configuration is disabled
Bugfix: Random shutdown issue
Looks like ZHA devs are working on making this firmware flash-able OTA.
What about zigbee2mqtt? Does the users in z2m need to do something extra to bring the firmware to the switch, or maybe the regular OTA update feature in z2m covers that already?
You can already flash this with ZHA if enable OTA and then manually copy the OTA file(s) to directory:
https://www.home-assistant.io/integrations/zha#ota-firmware-updates
https://github.com/zigpy/zigpy/wiki/OTA-Device-Firmware-Updates
However I have not yet read about any developers working on adding OTA provider to zigpy for it, see:
https://github.com/zigpy/zigpy/issues/535
https://github.com/zigpy/zigpy/tree/dev/zigpy/ota
It is currently manual for Zigbee2MQTT as well as no OTA provider yet in zigbee-herdsman-converters:
https://github.com/Koenkk/zigbee-herdsman-converters/tree/master/lib/ota
I should have known that anything Sonoff and Zigbee would be complete rubbish! Just like their motion and door sensors.
My fault for believing YouTube HAHA
Is there any updates on this for ZHA?
Thanks 
Looks like with zigbee2mqtt the firmware OTA is supported, at least per the release note of 1.25.2
Anyone know if this has a “smart bulb” mode where the relay doesn’t actually change the power state of the bulb?
Do you mean “detached mode” (where toggling the switch is separated from toggling the relay)?
Yes! I think that is it… a quick google seems to say the zbmini-l is not capable of this. To bad…
I have installed my replacment device 3 days ago, (original device was doa). I needed to modify hole in my wall and go deeper inside of wall to put this device in, and i needed to cut 2 corners on housing so that now pcb stick outside but i have just enough space to jam this into wall. So this device its no so MINI. But other then that device work just fine inside HA using sonoff integration and sonoff zbbridge.
What load do you put on it? I found my led lights are still on (flickering) when the switch is turned off. Anyone else know how to solve this?
I have 5 9w led bulbs with samsung chip, something like this:
https://www.v-tac.eu/products-view/house-garden/led-bulb-samsung-chip-9w-e27-a58-plastic-6400k-detail.html
I did not see problems using this device
Ok, so 45 watt, that is significantly more than my 8 watt - anyone try a bypass on this switch?
