Is it possible to program an analog input of the Venus GX to turn off any charging source in the Victron components connected to the Venus GX (eg. MPPT or inverter/charger) from an external 2 wire relay? Eg. external BMS/push button/rapid shutdown etc.
I can use the external 2 wire relay source to power a BatteryProtect or a relay to disconnect the battery output of a MPPT, or connect the 2 wire relay into the MultiPlus to stop charge but it would be more elegant to do it via software.
This is exactly what I am looking for as well. The Venus GX has the ability when connected to BMV 712 W/temp sensor to complete the task. I think all Victron Smart Chargers now have the ability to stop the charge process below a set temperature. I don't understand why it has not been done through Venus GX/Color Control yet?
Same Question but title should read
Venus GX to turn off charging source from digital input.
I have a Cerbo GX a MultiPlus and a MTTP. I have a custom Lithium Battery with allow to Charger and Allow to Discharge Dry contracts.
I can control the MultiPlus with the digital inputs, info here.

But if I have the MTTP connected to the GX device Via a VE.Direct cable I can not use the VE.Direct non-inverting remote on-off cable.
How can I stop the MTTP Changing by a relay and have the MPPT connected to a Cerbo GX ?
I wonder whether anyone can answer jon-lobank’s question? In my case, I would like to know whether a temperature alarm from a SmartShunt can trigger a Venus GX to stop an MPPT from charging.
I wish to swap to LiFePO4 batteries in a remote setting but have no way of blocking charging when the temperature nears freezing.
using a smart shunt together with a smart MPPT should give you the requested function as they communicate via the VE Smart Networking.
