Is there a way to collect and store external environment temperature, or even estimated ‘weather’ temperature data for correlation and analysis with other system installation data?
If not, then this would be a useful enhancement (adapter) for the Victron inverters.
I’m no MQTT or Node-Red expert.
Hoping there is a simpler plug and play solution, either physical temp. unit or an API based integration to pull in weather data.
Home Assistant can do that and a lot more.

i´d use VenusOSlarge fpr that - NodeRED
As you say you are not really familiar with it - chatgpt is really good in solving such things - it suggests complete flows
I use two Shelly H&T sensors that continuously log temperature and humidity and make the data available via the cloud. Here are my outdoor temperatures for today:
The data can also be exported for further use.
But perhaps a small Node-RED flow would be more helpful for you. With Node-RED, you can easily access the VRM API and query the yield forecasts that Victron calculates for your system based on weather forecasts and constantly updates. I use this data to set the GridSetPoint of my ESS accordingly.
Node-RED is included in the Venus OS large image. You need to install it, and then you’ll have a very powerful tool for configuring your PV system.
