Battery temperature not reporting

I just installed my victron setup not to long ago and I noticed that I am not getting any information about the battery temp. My setup consists of a multiplus 2x120, lynx BMS/distributer, and two smart 160 batteries in parallel.

The issue I am having is I am not seeing the battery temps being reported in VRM. it was my assumption that the smart batteries would be able to report their own temp. I can see the temp in Victron connect when I connect directly to them but that info is not getting pulled in for some reason.

I have turned on MQTT and am looking at the raw outputs which also don't seem to be pulling temp from anywhere.

Is there something in the config that I need to turn on to get Lynx to pull the temp from the battery? I am concerned that from what I can tell, the system doesn't know the battery temp and if so doesn't have the proper information to change things based on battery temp

Hi @Matthew Shea,

the SmartLithiums report their temperature only via Bluetooth (VictronConnect). There is no other way to see them.

is there a plan to change that in a future release? seems that it wouldn't take much for the BMS to pull that info and report it up to a GX device. seems odd to have to run a temp sensor to the battery compartment when the batteries have their own temp monitors built in.

Sorry, I have no idea if this is going to happen. The communication between the batteries is entirely via BMS cable while the temperature of the batteries are only communicated by bluetooth.
