i’m new in the world of smart home.
i ordered a rasparry pi 3 and installed openhab2 successfully on it
now i would like furhter. i realized that i need some stuff from z-wave and some stuff from homematic(ip).
is it possible to run on the same rasperry pi both modules in parallel one on the serial on with the pins and the other via USB?
or do i need a second rasperry pi to split it. one with zwave the other with homematic.
i am also new with OH ( raspb 3 + openhabian )
but i use a 434 MHz Modul via USB (Arduino Nano) and think adding another USB Stick (zWave) shouldnt be a problem, also i am setting up homegear in the near future ( for homematic ) with 868 MHz Modul
In case of RaspberryMatic to support Homematic IP I would use a separate Pi for it since RaspberryMatic is a very limited Linux and most of the Unix infrastructure for running other services is missing in this distribution.
When it comes to HmIP there are also other options available besides a dedicated device (CCU2 or RaspberryMatic). Take a look at piVCCU or YAHM as well. Both provide a means of running the CCU2 firmware in an lxc container on a host (e.g. raspi or even a tinkerboard)
Well, I only know very little about differences between HmIP vs. HmRF. May be the only thing is that HmRF series seems to be dying and HmIP is the safest bet for the future.
In my opinion, the HmIP line ist targeted to the enduser, is polished and a closed system.
While the Hm series targets the technically advanced user and is an open system.
