Sure. My Smarthome journey started with some 433 MHz plugs and RPI Control software (rather unknown one) years ago. Followed by fhem + deconz and now HA. I moved my ZigBee setup to Z2M + sonoff dongle-p.
The reasons (please any of the devs, don’t get it wrong). That are really my personal reasons and I don’t want to blame anybody or anything:
GUI (deconz is not as easy to work from an tablet/Smartphone with VNC). Also with phoscon, you cannot configure or even see any device on the network)
OTAs (they mostly just work on Z2M)
Integration in HA
Just play with something new
As said above, just my personal thoughts.
I made that decision to have a better admin experience. Sadly, we all have real life besides our hobby
@Mimiix i hope you stay civil and respectful! As I am.
