Trying to add a Homematic IP radiator valve (Evo) to my home assistant installed on a RP3. Please help me understand a few things

Third party integrations

Hi, Here is my setup. I have tried to read up on this but a few things are still not quite clear.

  • I have the latest Home Assistant OS installed on a Raspberry Pi 3
  • I have a Homematic Evo radiator valve thermostat ready to be installed which either requires an Access Point, or a CCU according to Homematic.
  • I have installed the Home Assistant addon Raspberrymatic (Installation HomeAssistant · jens-maus/RaspberryMatic Wiki · GitHub)
  • I do not own the Homematic Access Point or a CCU hardware
  • The only two hardware involved here are the radiator valve itself, and the raspberry pi on which my Home Assistant is installed (and this home assistant runs the raspberrymatic addon which apparently serves as a virtual CCU)

Here’s my questions:

a. Do I need an additional hardware for the CCU or an Access Point with current setup? If yes, what should I be looking for?

b. If not, how can I add the new radiator valve thermostat to the raspberrymatic devices as a new device?

Any help is appreciated.

Thanks!

You need a CCU and I think the raspberrymatic is actually emulating this, but then you also need a RF-module, since the Homematic IP system is not using WIFI.

I use Debmatic, where they have a list of modules.
I think they all work on RaspberryMatic too.
I personally went with the HmIP-RFUSB.

Here is the list:

  • HM-MOD-RPI-PCB (HmRF + HmIP Funk)
  • RPI-RF-MOD (HmRF, HmIP Funk + HmIP Wired)
  • HmIP-RFUSB (HmRF, HmIP Funk + HmIP Wired)
  • HmIP-RFUSB-TK (Telekom Version, nur HmIP Funk, Firmware Updates nicht möglich, Funktionalität nicht dauerhaft sichergestellt)
  • HM-CFG-USB-2 (nur HmRF, nicht bei ARM64)
  • HM-LGW-O-TW-W-EU (nur HmRF)
  • HB-RF-USB (abhängig von Funkmodul)
  • HB-RF-USB-2 (abhängig von Funkmodul)
  • HB-RF-ETH (abhängig von Funkmodul)

Thanks a lot. I wasn’t clear on the RF module. I went ahead and ordered the RPI-RF-MOD
