Works great in my humidor. A lot more accurate than the cheap hygrometers Read more

Works well and the Bluetooth feature is a big plus. I have purchased many products from AC Infinity and will continue to. Great products, great customer service. Read more

Can be mounted on the wall with an included screw and drywall anchor, or stuck on something with its built-in magnet, or stood upright on its built-in kickstand. Talks to its app over Bluetooth. Tracks temperature and humidity and allows you to see trends easily. Can set low and high temperature alarms. Took it out of the box, inserted the included batteries, and was up and running. Checked it against an old school analog thermometer and hygrometer, and this device seems very accurate. Great in general, let alone for the price! Read more

I was hoping this would be able to be used as a trigger for the controller 69 but while it uses the same app to view the temp/ humidity it doesn't let you set triggers for other controllers. My set up has two tents using a single controller 69 to handle the exhaust fans and was hoping to be able to use this as a second temp prob to further customize programing of how the controller 69 ran my fans. I couldn't find any information on of this device would work the way I wanted so I decided to try it out. It is nice to get extra data from my second tent and the price isn't completely unreasonable so even though it's not what I was hoping for I am keeping it. Seems like they have a better model available that's only $5 more that has an external prove so you can track temps in two places on once device. For some reason it is impossible to find and not even listed on Amazon. This isn't my man issue but more of an annoyance as it's only slightly more for a much better product. This sensor itself seems like the temp/ humidity is slightly off (had this issue with other ac infinity sensors) the app let's you set an adjustment offset so it's minor but if you don't have something else to check it against do keep in mind it may be not accurate. It was simple to connect with the app and shows a helpful chart of data. Overall it does it's job but the superior model that's retail is only $5 more should be the model widely available as it's basically the same thing with an extra probe so you can see temperature inside and outside a grow tent. If you were hoping to somehow use this to trigger an action on the controller 69 it is not able to. Not sure if it's a technology limitation or if it's something that can change in the future Read more

Used it with the ac infinity dome kit, great for monitoring your plant, a set of batteries should last you at least 1 grow session. Works perfect for me. Read more

This device is great. It has a magnetic back so you could stick it anywhere or you can use the built-in stand or just place it anywhere you would like. There’s a Bluetooth app that lets you engage enhance functionality like alerts. The size of the device is great for smaller areas or grow houses. At under $20 this thing is great. Read more

When the product is working, it's great. I've had it for 5 days, and it took maybe an hour to settle in to the conditions, between humidity & temp both. I bought this to be able to export the data it's capturing so I can track it in line with my grow. However, it's had 5 large gaps in coverage. These gaps are anywhere from 15 mins to 14 hours. The longest it's worked in one go is 13 hours. It has only worked that long in one go once. More often than not (3x) it's only worked consistently for 6 hour stretches. These are 4 column CSV's that are exporting off this thing. This is not a large amount of data being captured. As a hobbyist, this is insufficient. I expect 100% uptime. I expect the app to tell me when the on-device storage is full, so I can export and clear it out. But instead I'm getting huge gaps in capture. Read more
