Low temperature cut off with Venus temperature sensor

Dear all,

I have a LiFePo Battery which is connected to a MPPT 150/35.
The MPPT is connected to a Venus GX via VE.Direct.
The Venus GX has a temperature sensor connected.

I need to disable the charge of the battery below 5°C.

My first idea was to setup a VE.Smart Network with a Smart Battery Sense, but in the FAQs there is information not to use this if a Venus GX is connected.

The next idea was to use the Venus temperature sensor with the "Shared Temperature"-Feature, but I found out, that this was planned for Venus OS v2.20, but then not released.

I have read that "Shared Temperature" is only available in connection with a BMV-702.

So the only solution is to use a BMV-702 with a temperature sensor and the "Shared Temperature"-Feature enabled in the Venus GX or is there any plan to include the Venus Temperature Sensor in the near future?


What is the best solution for a temperature cut-off in combination with a Venus GX?


Thank you

Martin

Hi @MartinK, most likely that is to wait for Venus OS v2.40; due for release any day now.

I’m 99% sure that it will be able to do what you’re looking for, but now have no time to go through my notes; sorry.

I found this thread and would like to confirm how to set this up... I too have a temperature sensor connected to Venus GX, but I can't find it in the the DVCC.

How to make the GX-connected sensor appear on the DVCC list of temperature sensors?

Ok, my bad. I found out the issue!

One must select the right type on the Sensor setup page:
