How to use both cerbo gx relays and a relay in the multiplus 3000

Q&A and troubleshooting

i have a multiplus 300012v and cerbo gx along with a bunch of victron solar chargers, lynx products etc.

i currently use both relays on the cerbo gx (one for autogen start and the other to trigger a victron 104 digital relay to control 12v lights) i want to use another victron 104 relay to control a whisper fan to cool an rv compartment. the multiplus has a relay output on it. i cannot see where to control that relay when i already use the 2 on the cerbo gx. i want to have the fan relay triggered with a temp sensor. how would i control the relay on the multiplus.

thanks

The relays of the MultiPlus can only be configured with VE.config.

i will try that tomorrow. can you see them or control them once configured via vrm?

thanks

No you can’t see them in the vrm.

The other way is to control other loads is to use smart switches and node red.

Or with something like a shelley to also combine a physical switch and smart switching.

Or you could wait for the new digital switching unit from energy solutions, not sure of the release date or exact specs. The next firmware release for the Cerbo, V3.60 will have newer switch functionality in Node-RED.
