I’m also dispatched to the ‘garage’ for my single plant grow…I try to monitor as best I can. The mason monitor just arrived and i decided to check it against the tent monitor…
I’m not trusting the china stuff…
I found this humidifier works very well for our small tent…
Im new to the ac infinity data should my tent’s data look like a sine graph? Im not sure how work the app to achieve a graph like yours.
AC-Infinity data dependent upon physical parameters being measured.
My de-humidifier, cycles hourly into a done mode and RH shoots up.
Then back down. Welcome.
Take it from me Growmie…you’ll drive yourself crazy chasing VPD numbers. In a controlled and stable environment it’s easier, I try and keep my environmental conditions in range with temps varying from 68-82 and RH of 45-75% through the 3 growth stages 
Seedlings: temps at 76-82 RH of 65-75%
Veg: temps the same and I drop the RH to 60%
Flower: temps 68-78, RH of 45-50%.
