It is possible, but this kind of functionality is not available “out of the box” yet.

It is being actively developed by enthusiasts.

You can search the discussion of independent work on VENUS (the operating system of the Venus-devices) here:

https://groups.google.com/forum/?nomobile=true#!forum/victron-dev-venus

A sample discussion for example is here:

Work from this group has been rolled into the mainstream Venus releases in the past, if it proves to be useful and once it is tested and stable.

Bump. With the new smart shunt's loss of the built in relay, a few of us with third party battery management systems use that relay to disconnect charge sources when temps approach freezing. It would be nice to have a few more options with the relays with data already being sent to the GX.

The tank functionality already exists (in v2.60-4 at least). In Relay select Tank pump as the function and in Tank Pump, select the tank sensor you want and fiddle with the start and stop percentages until you get the relay behaviour you want. I haven’t tested it myself (waiting on a way to calibrate my non-standard tank senders to get sensible readings) but it looks like it should work.

I haven’t seen any way to achieve a similar thing with temps.
