I have a SLZB-06 which has been flashed to do Zigbee+Bluetooth. My current firmware is Firmware: 1.51 (ESPHome 2024.9.2).
Is there a way to update to the latest firmware? I looked but could not fine any information on how to update (after the initial flashing via USB).

Normally you could do it through the devices web interface. But, by adding bluetooth to the device, you lose that.
I believe the only update path is flashing via USB again.
Yes. No web interface.
There must be some other way to do an update.
I’ll keep searching.

I just told you the way.
The company is quick to reply. Contact them to get the same response.
No point in contacting them if the response will be the same as yours. Sorry, I mis-understood your original comment. When you said “I believe the only update path is flashing via USB again”, I didn’t realize that you meant flashing was definitely the only way to update.
I’ll re-flash.
Thanks for the help.
