low temperature cutoff

I have the MultiPlus 24/3000, and the Smart Solar MPPT 150/100, Cerbo GX, and the LynxShunt and Distributor. For the temperature sensor, I'm using the one that came with the LynxShunt, and connected it to the temperature port in the Lynx Shunt unit.

Recently I have been getting subzero temperatures the last week or so. The MPPT 150/100 has a low temperature cut off at Celsius 3 degrees. But it doesn't seem like the MPPT 150/100 is reading the temperature on the LynxShunt.

In the mornings, right when the sun comes up, the temperature is still hovering right around 0 degrees, and I noticed that the MPPT solar charger was starting to kick in.

So anyway my question is, can the Lynx Shunt share its temperature readings with the MPPT Solar Charger? I know that the Lynx Shunt doesn't have BlueTooth, and it doesn't seem to support the VE Smart Networking feature, which makes me wonder if its actually sharing its temperature measurements with the other devices or not?

Can someone shed some light on this?

I'm assuming the internal BMS on the battery will ultimately kick in and won't allow any charging during subzero temperatures. If the Low Temperature Cut off on the MPPT charger fails.

Sounds as if you're using Bluetooth for the MPPT and cables for the Cerbo. These networks aren't aren't compatible. Try using a VE Direct cable between the MPPT and the Cerbo.
