Cerbo relay2 function

Cerbo relay2 with added like the genset control for diversion control and olther?

May be Victron if they listern that the second relay 2 in the Cerbo should have this added as function instead of only a simple temperture control?

As this function works very well in sites i have set up, but if was in the Cerbo it would much easy for the client to change than trying to add a assistant.

programmable relay (size:30)

*) Use primary programmable relay.

*) Set relay on

*) when SOCHigher than 99%.


programmable relay (size:30) 1

*) Use primary programmable relay.

*) Set relay off

*) when SOClower than 95%.

Note: Up date started to add extra code for the relay2 function called Diversion load for the raspi then for the Cerbo GX.

Hi @Rob Duthie,

If you are looking for multiple programmable relay functions on the Cerbo GX, you might be interested in the node-red functionality.

This is able to be used on relay 1 & 2 - and gives incredible flexibility for more complex and customised multi relay control systems applications.

Hi Guy

This needs to be added into the Cerbo, not node red as this is for clients to use as they are not programmers and are not interested in complex node red set ups.

It should be added in the cerbo to give it a more better use on this relay that seems a waste.

You as the installer can create a NodeRed dashboard which is accessible from VRM separately to the NodeRed programming side.

This will allow your clients to just see buttons for the options you have made for them.
We use this all the time.
