Car Temp Logger with HA / InfluxDB/Grafana

Hi all, not sure if this is the right forum to post this on but was looking for some help.

I’d like to be able to log the ambient temperature inside my car (not the engine, where the humans reside)

I can hook up a temp sensor to a nodeMCU and wire it up to the 12v battery fine but I’m trying to figure out how best to pull the data from it. I run HA on a Pi4 in my house that has InfluxDB and Grafana and my idea was that when I pull up outside my house, the nodeMCU would pick up my home Wifi and HA would pick up the nodeMCU and parse the data log into influx and be able to show it in Grafana.

Would anyone have any insight on where I can look at to archive this? My skills in InfluxDB are limited so I definitely need to learn more in this area - not sure if I’m even barking up the right tree here so I’m absolutely open to suggestions to achieve this another way!

Thanks in advance
Andy
