Hi,
I am currently running Homegear on a Raspberry Pi (using a CUL stick) and several MAX components.
Now I plan to add a Keymatic door lock.
I read that keymatic only works with original HM components because it requires an AES handshake.
So my question is: Is it possible to simply replace my CUL stick by a HM-CFG-USB stick adding support for AES while still being able to use my MAX-components?
Thx,
chris
Hey chris,
no, you need two physical interfaces: One for MAX! and one for HomeMatic. Using the CUL for both at the same time is not possible.

Hi Sathya,
thx for the quick reply!
But at least I could use an additional HM-CFG-USB stick to get full access to the keymatic right?
Is it safe to do so? I read somewhere that the USB-stick has an issue with AES.
Is it safer to use a HM-CFG-LAN device instead?
Thx again.
chris
Hey chris,
Yes
Yes
We thought so, too, but it turns out, when you change the AES key, everything is alright.
Not safer. If it’s the better solution, I don’t know. I never extensively tested the HM-CFG-USB. On the Raspberry Pi the latency can in theory be quite high on hight CPU load, USB or network usage. But I don’t know, if that’s relevent in practice.

OK - thanks a lot for the enlightment !!
