How It Works

Defective - another on the way.

Hasn’t connected yet, waiting on a replacement unit. Didn’t work out of the box.

J.D. (Oregon, United States)
Easy to use but not suitable for high RH environments

I set my Pulse One up and was very excited to see real-live stats from my phone. App is easy to use. Wrapping the cable cord around the case was a bit hard especially since it gets in the way of the lid when opening the device (to access the power/reset button), but it’s not too bad if you’re not doing this often. Unfortunately, the device is not meant for humidity > 80% and it tells you to remove it after it reaches 95% RH to avoid damage. I guess I won’t be able to use it for the tropical rainforest environment I’m setting up. Other than that limitation it worked great!

So much valuable data at my fingertips

The app is fantastic, I can log in anytime from anywhere and see exactly what's going on in my greenhouse. I get alerts straight to my phone when anything goes awry. I have learnt so much with these monitors with regards to temperature fluctuations and they've enabled me to really be able to give my vegetable seedlings the best start in life!!

Pulse sensors work great

I have three pulse sensors.
They are reliable and accurate and allow me to focus on other aspects of the grow.

It's key to be notified early that maybe light didn't turn on at the right time, or humidity sky rockets because there is a leak.
The app is excellent and now that I can view it on the desktop of my m1 mac as well it's even more useful for me.

Game Changer

Pulse One makes my days so much easier.
It gives me full control all the time.
I can’t grove with out it now.
