I highly recommend an Elitech RC-4HC if you want to start making use of the logger data. It costs about 25 USD and is well worth it.
I just upgraded to a couple of RCW-800WIFI loggers. No more manually pulling data - all cloud upload. Elitech mostly does commercial cold chain monitoring so their cloud product is actually a good buy. I paid around 22 USD to upgrade access to cloud based graphs (free CSV download without the graphs). Adding my second RCW-800WIFI cost NOTHING.
You can check Week5 of my current diary for a screenshot of the cloud platform. One thing to note is that I actually make my own graphs using google sheets since I now have custom graphs for the following: Optimal VPD, Temps, RH%, "lights off" times have been added to these graphs, and most recently I have been comparing my lung room logs, my tent logs, and imported weather temps as well. I have screenshots of the homemade graphs in Week10 of my current "Let's Do Some LST"diary.
@NegotiatedBubble, thanks so much for all the info! I'll definitely look into these loggers, not having to manually pull data would be nice lol. Eventually the plan is to build an Arduino based system that I can add and remove sensors to as I need, host all the data on my local network, and build out a simple desktop app for monitoring. That's pretty far off though, so these may be a good solution in the meantime, or at least a source of inspiration β¨
