OTA for Ledvance using zigbee2mqtt

I’m trying to update a Ledvance outdoor plug (SMART+ Compact Outdoor Plug EU), but gets an error when I search for updates. I think I have found a new firmware but can’t update. Is it possible to “manually” upload a firmware via z2m to a device?



Firmware for Ledvance:

Thanks in advance

Same problem with every single Ledvance bulb I purchased. Firmware Update shows in Zigbee2MQTT as well in Home Assistant. Can’t update regardless which option I try.

There is another topic here about someone with the same issue. Also bulbs like me, probably even the same model, but since your post here about a power plug but the same company, I can only assume the difficulty exists with every Ledvance Zigbee device they sell.

I have searched for a year now. I asked multiple people. Nobody knows how to update the firmwares on any Ledvance Zigbee products.

I will avoid buying any product from this brand in the future because everywhere I searched and asked, nobody knows how to do it. I even disabled the update checking in Zigbee2MQTT, but the devices still keep showing an update is available without letting me update anything.
