question

There is no input for a temperature sensor.
I'm not sure if you will see a battery temperature if you connect a sensor to a SmartShunt.

Hi - The new Beta version of the Globalink 520 software supports Ruuvi sensors, so you can use this: https://community.victronenergy.com/questions/138150/globallink-field-test-firmware-v206-beta-122.html

I noticed there is an "Internal Temperature" for the Globallink, but it seems like its not sampled on each report? You can get it on Custom Widget and as an Alarm reference.

I watched this video about the Ruuvi / GlobalLink integration, did it with my GlobalLink and it works great. https://youtu.be/393Pb_iRJOo

I have two Ruuvis on my globalLink that works great. I also have two smartshunts with thermomether connected via cable. The temperature readings only works sporadically in the graphs in custom widgets. They are selectable, but only gets a few samples per day (at best, some days are entirely without samples). The Battery Summaries under advanced however shows sensible values all the time, but i suspect they are just based of the last sample on the graphs. So money wasted on those sensors for me.
