Russound CAV6.6 / CAA66

I’d like to be able to control either a Russound CAA66 or CAV6.6 without keypads (via app). Can I use any Serial RS232 to Ethernet device in adapter with OpenRemote or do I need specific brand RS232 to Ethernet device? If anyone is using one of these Russound’s with OpenRemote, could you please let me know what model adapter you are using?

I use a serial connection, a USB to serial adapter actually. In this way you just configure the serial device in Openremote. I can not tell you about Ethernet serial adapters.
