Choosing Rolladenmotoren for Classic and IP Actors

Hi everyone! I’m currently renovating my apartment and we’re getting some new roller blinds installed. I’ve been using a CCU3 system for a while now and I’ve got some classic HomeMatic actors from a friend. They’re the ones linked here (https://de.elv.com/homematic-funk-rollladenaktor-1fach-unterputzmontage-hm-lc-bl1-fm-fuer-smart-home-hausautomation-076799?fs=3431210242). However, I don’t have enough of these classic actors, so I’ll need to get some HomeMatic IP actors as well (https://de.elv.com/homematic-ip-rollladenaktor-hmip-froll-unterputz-auch-fuer-markisenmotoren-geeignet-151347?fs=3635596933&c=742). I’m planning to use switches with these actors, specifically the Somfy Ilmo WT motors. I’ve come across some information in the ELV forum, but I’m still not entirely sure about a few things. Here are my questions:

  1. Can the classic actors be operated with the CCU3?
  2. Are there any differences in functionality or features between the classic and IP actors?
  3. What should I look for in a rolladenmotor to ensure it’s compatible with the actors I’m using?

I’d really appreciate any advice or insights you might have! Thanks in advance, and I look forward to hearing from you all.
