Brilliant Dimmer Mechs no longer flashing

Hi,

I have previously flashed 3x of the Brilliant Dimer Mechs without issue using Tuya-Convert on my Pi3.

I purchased three more of these mechs today, and they are not flashing when using the latest version of Tuya-convert

**Device Name:** Brilliant Dimmer Mech [link](https://www.brilliantsmart.com.au/smart-products/electrical/smart-mech/)
**Revision:** Item marked with "2020-23" printed on the side
**Tuya-Convert version:** 2.4.4
**Logs:** See attached

The item is put into flashing mode by pushing the mech 9 times in succession (mech led flashes quickly).

After the start_flash script is run, I join my mobile to the vtrush-flash SSID, and press enter.

At this point, the smart config pairing procedure starts, and it seems to register with the mech, as during the first run of "Resending SmartConfig packets" the light globe pulses momentarily.

But the resending attempts reach the 10x retry limit and end, without the device being flashed.

Logs are attached, thank you in advance.
