I can control my Multiplus through the VRM and a GX LTE whilst away from my boat which is great, but i would also like to control other loads that are fed through a battery protect.
Is there a way to do this?

Remotely switch Battery Protect on and off through VRM
Assuming that is the discharge enable pin, why not?
Run the yellow wire through the COM and NO relay contacts.
Those devices are connected to the GX. There is no way to connect the BP to the GX via VE.Direct or other communications method.
There is a remote switch:
It would be cumbersome and very manual, but if you had a BMV-7XX with a relay, you could open and close that relay with VictronConnect accessed through VRM, but you would have to play with the settings each time, i.e., it's normally closed, but you'd open it when SoC drops below X. You would have to change X to be above the current SoC to make it work.
I suspect that you could also program Relay 2 on a Cerbo GX by spoofing the temperature to get it to turn on and off by changing the temperature above or below actual.
Neither solution is remotely elegant. There may also be wifi based relays that could open close via a phone app completely outside the Victron ecosystem.
Hopefully, someone knowledgeable will come along with a better solution.
Thanks.
It seems a real pity to not have this as an obvious requirement.
I can turn it on and off through Victron Connect if I am within Bluetooth range, so why not through VRM?
I want to be able to turn on various things like the fridge or heater a few hours before I go to the boat but don’t want to leave the 12V system live all the time.
i read you can now
