It would be really nice if the SmartShunt Tx port could be configured for alternate functions, similar to the MPPT solar chargers. On which you can set for example a voltage based load-disconnect or a streetlight function.
For the SmartShunt, it would seem obvious one would want a SOC based load disconnect, though honestly any of the already configurable alarm functions could be useful.
Personally, I would not even put a disconnect relay on it, just a piezo buzzer.
Hiu @cybermaus,
Sorry it's taken a while to respond to this, It sounds like a good idea to me.
I have forwarded on the feature request to R&D.
Great, thanks.
For a tiny camper like mine, such a simple, low current use (as compared to full Cerbo GX online monitoring) solution would be great, even if the signal is a simple alarm on/off signal.
Now, at the danger of over requesting: After I made above post I was thinking a bit about the practical use of such a buzzer, and it may be good if they made an option for an "intermitted pulse".
After all, when a battery is already at low SoC or low voltage, we want to reduce even the few mA of a buzzer, especially when continuous.
So something clever like: pulse 1x per second if there is battery energy draw. But do that only for 1 minute every 15 minutes if there is no energy draw (which is likely when camper is unattended)
But I am sure your engineers can think of even cleverer solutions.
