Accessing Relays via Cerbo-S GX

[don3128 (don rakers)]

Hi All, newby to the group and very excited to be on the learning journey of Victron products. I’ve just been scrolling through the web trying to find an option to access 4 relays on an antenna switch that i can access through VRM to a Cerbo-S GX. It looks like it can be done using a RasPI something i have never done before but would love to have a go. I have setup a remote HF radio station with a HF radio and remote control hardware unit that is connected to a 5G modem. It is all powered by 12 volt batteries that are solar charged through a Victron controller. I havent connected the Cerbo yet but am gathering info on how to use relays which will be simple on/off so any help in the right direction will be appreciated greatly. cheers, Don
