This connects using the app. I COULD NOT CREATE AN Inkbird.com account.
Arrived quickly and in perfect working order.I won’t deduct stars for this as I was able to get the app to work.The directions say you need to sign into Inkbird.com or create an account. I went to their website and tried to create a new account as a new customer. There is a process you get a security code and you create a password. It would not accept the code and eventually have me a message: Sign in error with no code.I tried on Firefox, Opera, and Chrome all giving the same result. I mention this so Inkbird can fix this.The packaging is very nicely done.The device is very handsome looking.The sensor is permanently connected and the cabel feels very sturdy. The tip is stainless steel of good sturdy quality.The plug is 3 prong and also sturdy.The plugs have a small etched symbol for heat and cooling. These can be hard to see and tell what they are.Overall build quality is 5 stars.The directions that come with this do explain the button dial on the side a little. If you look under more product information you will find 2 PDF files one a manual and one for a more or less quick set up.The connection is easy overall.If you also can’t make a Inkbird.com account on site.Download the Inkbird app. Create the account. It might tell you it has been made and when you try to sign in it says email or password are incorrect. Just hit forgot password and reenter your password, you get a pass code for security and enter it last then hit enter. It should say you’re good.Now go back and enter the app. For some reasons this doesn’t as farcas I know transfer to the site.One in the app it has to take several minutes or so to load and find your device. THIS CONNECTS USING THE APP not your Bluetooth list on your phone.Once the app loads images of all sorts of devices as long as yours is plugged in it wil show up automatically or at least mine did in a field above the other products.Just follow the onscreen directions.You should be connecting very soon after.The code the device starts with only goes away after you set things up.At the last step it shows it connecting and presto you’re connected and the temperature ð¡ appears.The app is straightforward and does what you would expect. It’s a thermostat and settings app. Not a AAA game here.Personally I give the app 5 stars also.The temperature seems very accurate and should perform well for my needs.I will be plugging a battery warmer into the heat plug and laying over my large Bluetooth speaker to keep warm in my un-heated garage.I am not deducting stars for the app connecting to the device. Because once I realized that the connection was straightforward.

Just what I need and works great.
So as the title says, this product is just what I need for precise temperature control in my fermentation fridge. It may or may not be just what you need for your particular application, so I would encourage everyone to read the specs carefully and make sure they’re getting what they think they are before buying.Having said that, this controller works great for me. There are two modes for controlling temperature and I still haven’t decided which one I like better. One mode works just like the older ITC-308 series where you set a target temperature and differentials for heating and cooling. In the other mode, you set start and stop temperatures for heating and cooling separately. There are also day/night and timed modes which I imagine might be very appealing to some users, but I haven’t tried those because I don’t think I’ll ever need them.In any case, both temperature control modes can maintain my fermentation chamber within a very narrow range. At first I was rather conservative with it and set the heating and cooling three degrees fahrenheit apart, but eventually found that I can set them just one degree apart and it will maintain the temperature within a tenth of a degree above or below that range. Of course, I imagine that the specific heating and cooling units that you’re using, as well as probe placement, might have an impact on this as well.The app was easy to download and install, and worked well for me once I played around with it a little to get a feel for it. The bluetooth range is pretty good in my house, but again this is probably something that will vary for different users. To me, it hasn’t really mattered much because the controller keeps working even if it disconnects and stores temperature data that you can recover when you reconnect. Since I use my phone to run the app, it’s always going to disconnect when I leave home, but it always reconnects when I return.The only negative for me is that I do wish that the temperature probe wasn’t hard wired to the unit. Since I attach the probe to my fermenter inside the fridge, it would be nice to be able to disconnect the probe from the controller when I want to move things around instead of having to take it off the fermenter. But that’s a pretty minor complaint so I’m still giving it five stars.I may come back and post an update after I use it some more.

Good replacement for an old ITC-1000
I purchased this controller to replace an old ITC-1000 controller that I have been using for my keezer build.I was able to get the app installed on my Android phone, an account created, and the device added without any difficulties. Having the app made making setting changes a breeze. I no longer have to try to find the manual to figure out which of the 2 letter settings I should be changing. Being able to see the history in the App is nice to see how the keezer is keeping temps.I have so far been unable to connect the ITC-312 to my Home Assistant instance â there doesnât appear to be a pre-built configuration to talk to it via Bluetooth proxy.The appearance of the device is great â itâs nice an sleek, especially compared to the zip tied cluster of wires I had with the old setup.One thing I would have liked to see is a replaceable temperature probe. I did not have a hole cut for the sensor and had some wire abrasion, with this new setup I will need to cut a hole and install insert a grommet to protect the sensorâs wire.

Only good for1 aquarium using the USB
Never got a chance to see if this worked. I had three aquariums. 1 phone. So if I bought three of these exact same items, my phone would not recognize which one was which because they are exactly the same. This is as far as USB it’s concerned. I only bought these from the advice of a tropical fish store as I had to move my aquariums in my backyard from my new landlord. So I don’t even know if this works.I can’t give a review

Used to convert mini fridge
Bought this device to convert a mini fridge to a wine fridge. On its warmest setting the fridge was keeping my wine at 44° and by adding INKBIRD I now can keep fridge at a perfect 54°I would give it 5 stars if the temperature programming was a bit easier.
