For the past few years, I’ve been building a hydroponics controller DIY style and on the cheap. Long story short, it’s not as cheap as one could hope, but the closer I get to my goal of full automation, the more the expense is justified. That said, I offer that just knowing room air stats is not enough without also having the ability to do something with the information. I like the the OPs find, especially for the price, as I know technology can add up quick, and to have so much included in a single unit is a great value, though it would likely be wise to mount the device in a well vented area to dissipate heat. I actually might discontinue using my current temp/RH sensors and go this route, but only if I can intercept some of the data feed. Gotta do more research I guess. I’m glad I found this thread and am so glad this site has been resurrected!
