VIVOSUN Digital Hygrometer Thermometer, Humidity Meter with Probe, App

I got this for my dry room and I love it. I’ve shopped Vivosun for years now and they have come so far with all the new stuff. They are starting to get pricey like everything else but I've always try to let people know this is the best equipment for the price and encourage people who wanna grow to use Vivosun

So I bought this little unit to monitor the VPD in my grow tent and trust me it works as advertised. Now the details: I have attempted to 2 other grows in the past but never had the results I wanted. So, this time i decided to see if AI could help. And it has bigtime, but through my reading I kept seeing the three letters VPD. So, what is it? It stands for Vapor Pressure deficit. It refers to the amount of water in the form of vapor in the air and is displayed as kPa. The ideal VPD changes as your plants mature. Whereas a seedling requires a VPD of 0.6 kPa and an adult ideal VPD is about 1.5 kPa. Bottom line. A few minutes after I had this set up, I found I was too low for the growth stage of my plants. And now (a few hours later) after a couple tweaks of my humidifier and my exhaust I am right at 0.8 kPa which is exactly where I need to be. Oh, and by the way there is an app so I can see this info on my phone. It is however only Bluetooth but does track all the details of the grow. Is it perfect? Well, no, what app is? But it is very useful and connects with other Vivosun Smart Grow System products. So much so that I may just shift from my current product line. And to get it for less than $20 Game Changer!

I was skeptical of Vivosun anything because everything I tried in the past was less than average quality and stick with AC Infinity but couldn't find a reliable temperature and humidity sensor that also comes with a probe that also reads temp and humidity. Unfortunately, most devices with a probe their probe only reads temperature, not humidity even though the unit itself reads both but not the probe. Thankfully, this Vivosun AeroLab TH1S is accurate right out of the box in both temperature and humidity (compared with 10+ thermometer/hydrometers in grow room & curing bags) but in case you need to calibrate it, you can certainly do that through the app which has a ton of other great features including Bluetooth connection and optional Wi-Fi connection via a small USB stick (cheaper option) or a controller 🎮 to monitor with other Vivosun products. ⚠️ NOTE ⚠️ The temperature and humidity stabilizes a bit slower than I'd like but faster than others. It's not terribly long because it gives a very close reading and then over the next 10-15 minutes it stabilizes and the readings change a couple degrees and a few RH percent

Easy to setup and accurate device, I had some issues with updating/refreshing my phone with updated data.. but could be user error or bad device connection.

Absolutely love this product and anything from this seller ty

Review is for the AeroLab THB1S Bluetooth Hygrometer Thermometer with the External Sensor Probe Included. The remote probe started failing almost out of the box. It started with intermittent readings, then complete garbage and the stopped all together. Prove less less than a week. At one point is showed a temp change from 92 F to -10.7 F in about two minutes. Tried the Vivosun tech support. They were still closed almost 25 minutes after supposedly being open. The phone message says there is a tech support chat, but there is NOT. Waited on hold for a few minutes and asked for a call back. Crickets since. I thought I would try and get the issue resolved, but its just easier for me to return it and get a new one. Thanks Vivosun for not only making a broken product but then doubling down by making it EXTREMELY difficult to get any type of support. On a side note, the main unit seems to work flawlessly so far and the BT range is impressive.

The app will not load historical data to current time. It’s always at least a day behind. For a while I t was not updating at all, giving the same historical data for 3 weeks Tried emailing customer service. They tell me I’m supposed to be less than 30m away. I’m upstairs directly above the thermometer. Even if I were to go side-by-side, it still won’t load correctly. They want me to take a video of it. How? My phone that has the app has the camera. Accuracy is questionable: I compared readings with 3 digital thermometers and it’s close with temp, within 5%RH. The probe is less accurate. I have the probe in an enclosure that reads COOLER than the ambient temp getting AC. How? I have also tried calibrating with other thermometers. Support has been lukewarm at best, half of the responses were ads to more products

Working great just wish lettering for the ranges were a little heavier or darker font

Edito reseñas q era buena ,pero se me averió uno la sonda ,de los 2 termómetros q tengo con sonda externa ,y al ponerme en contacto con vivosun ni una pega ,me envían uno nuevo sin problema alguno ,gran empresa y gran servicio de 10

Works perfect I love it. This company makes fantastic products.

I like this thing. I've got it hanging right in the middle of my grow tent and I can easily read the display from the tent flap. It integrates with my Vivosun app and augments my Vivosun E42A+ Controller(s).

Excelente
