Problems with adding new Homematic IP actors

Hey Guys,

I'm using a Raspi 4B with pivccu3 and HM-MOD-RPI-PCB. Installation seems to work fine. I get following output:

pi@raspberrypi:~ $ sudo pivccu-info piVCCU version: 3.57.5-57 Kernel modules: Available Raw UART dev: Available Rasp.Pi UART: Assigned to GPIO pins HMRF Hardware: HM-MOD-RPI-PCB Connected via: GPIO (/dev/raw-uart) Board serial: OEQ0310424 Radio MAC: 0x584B55 HMIP Hardware: HM-MOD-RPI-PCB SGTIN: 3014F711A061A7D7098E2498 Radio MAC: 0xB03ACB State: RUNNING PID: 945 IP: 192.168.178.25 CPU use: 15.06 seconds BlkIO use: 62.37 MiB Link: vethpivccu TX bytes: 17.61 KiB RX bytes: 35.16 KiB Total bytes: 52.77 KiB

But I can't add Homematic actors. The actors and HM-MOD-RPI-PCB was already working with Raspi 3B. The actors was many times resetet. What could be the problem?

Thanks a lot!

The Raspi 4B produces a lot of interference at 868MHz, which affects especially HmIP with its Listen-Before-Talk.
You need at least 50cm distance between the HM-MOD-RPI-PCB and the Raspi.

I‘m understandig. But how could I resolve it?

As said, you need at least 50cm distance between the HM-MOD-RPI-PCB and the Raspi, e.g. using GPIO ribbon cable or using a HB-RF-USB-2 pcb.
