The Pulse is an awesome tool

The Pulse products are worth every penny. It really helps for seeing problems that can be course-corrected before it's too late. It makes managing enclosed environments easy. I've been a firm believer that you can't manage what you don't/can't measure. This thing measures constantly, every three minutes. It is an invaluable tool.

I don't know

10 minute inputs make a really dirty sine wave

Absolutely the best grow room monitor.

After using two competing products, I tried the Pulse. The app works well and the alerts push through almost immediately. I will definitely be getting one for every room I operate.

Replacement Unit

Had a problem with the light sensor with my previous unit. These guys went out of their way to get me my unit and my system back up and running.

Unfortunately ups was hitting me with a large shipment fee for a unit that was a warranty replacement. I did enquire about any fees that would be incurred and was told it would be handled. Ups order was declined by me when fees were requested and now I am on the hook for the fee anyways. Pulse did go out of their way to send another unit through usps.

Anyways, the unit works well, it does a great job of notifying me on issues, and the environment where the pulse is monitoring is the healthiest and happiest in my grow.

Unfortunately ups and over the boarder shopping large fees by ups would prevent me from getting another or upgrading to the pro version directly from the company.
