3 months ago I used this converter, just changed the name, I'm not 100% it's ok but it works https://github.com/pvvx/ZigbeeTLc/blob/master/z2m/lywsd03mmc-z.js

I just got my MHO-301 and flashed it to v0120 firmware. I'm using it with the Z2M add on in HA and it is reporting temperature and humidity.
However the Z2M GUI (in which is shows up as a MHO-C401N-z) is reporting it as an unsupported device. Is that to be expected or should I be using an external converter?
Thanks
