I like this device. I started getting email alerts asap about major changes to the environment. Compared to Ac Infinity's newest controllers its much better by default, it connects consistently too. For c02 data it was reading the same as my Inkbird.
The light meter is a mixed bag, if you can place it stationary vs holding it,but watch Jeremy from build-a-soil's comparison review to get an idea if you really want to use an app or just read a meter like the Bugbee unit, cause this is much more work than a quick lux meter reading but you will get that spectrum data and some other numbers you wouldn't from the lux.
I would love to use these commercially if my license goes through, really nice product for sure.
