Works well, though the hardcoded app and software options are quite limited, leaving one with weird tradeoffs. An interface with more control functionality would be better. But then again, for the price, this product has very good value.

Very simple to setup and use. For the price I can now see my tank temperature and trending wherever I am. I have recently had heater issues and this will now alert me if I have problems.Like I stated, simple setup, I highly recommend downloading and connecting the application - then setting it up through the app. Very easy.It has been running for about a week now, if I have any issues I will update my review, but so far I highly recommend this model.

This is really an awesome product. The trick is understanding it. The manual is actually horrible, to be expected. But once you work through the details, you will absolutely love what this thing can do for your aquarium. I finally found a video on youtube, "benafricancichlids" That fully explained the functions and the different features. Don't bother with any of the other videos. Most of them have something wrong one way or another. Now that I have mine set up properly I absolutely love it. I have been watching it all day long. Step by step seeing how it moves through its functions and it is flawless. I've seen some reviews regarding the app, unfortunately, some of them are negative, but my experience with the app has been absolutely perfect. I hope you don't think that I work for this company because I don't. The neatest thing about this is that the aspect of controlling the temperature of my aquarium has always been a hit or miss, an unknowing, and a feeling of uncertainty. Now I feel like I have some understanding and control which is really a great thing to have when you're worried about your little fishy friends. I unfortunately lost a very, very valuable fish to myself due to my ignorance with temperature. And this is after thirty years of being in the fish world. Now I have this comfortable level of confidence. Get it.Update : what was I thinking? Where was I when temp controllers came out. I like to believe am up to date on most of my hobbies but this one slipped by. Let me tell you what I think about my Inkbird ITC 306A. I LOVE IT!!

Tiene problemas con sus sensores al variar las temperaturas marca un error no te marca la de temperaturas individuales de los sensores al cual deja de funcionar Por lo regular me marcaba siempre un error en cinco o cinco ahí

I’ve had issues with fish tank heaters failing - or worse - getting stuck on. Like many others, this has almost resulted in fish death. Luckily, I’ve caught it the few times it’s happened to me before fish were lost.After the last time this happened a few months ago, I decided to add an upstream heater control, and found this one quickly as it had fantastic reviews.I like the redundant heat probes with failsafe operation, the 0.1° incremental control, and the Wi-Fi control is really what sold me. It includes a detailed history log so you can go back and see what’s going on with your fish tank over days and weeks.The temperature logging seemed like a neat feature, however, it was really a big hit with me once I got it. It immediately proved its value. I recently installed a new air conditioner in my room, which has allowed me to keep the room at a constant cooler temperature year-round. Previously, I had issues with ick, which I traced back to wildly fluctuating FishTank temperatures due to wild fluctuations in room temperature. So I would keep the fish tank around 80° so it would maintain that temperature when my room would get hotter on hot days. Now, my room stays closer to 74° year round. I was able to balance this new comfortable room temperature with a very comfortable Fishtank temperature, with minimal use of the heaters. I was able to set the unit’s high and low triggerpoints very precisely using the log to avoid inefficient heater use. I settled on 74.5 on the low end and 75.0 on the high-end. The heaters only crank on if I decide to make my room really cold for a while. I know I could never get this type of precision with the old style heater control, and having the temperature log charts is what allowed it to be so easy. So, the Fish are happy, and I’m obviously using less power needlessly driving the heaters.I read a few reviews where people were trying to use this unit strictly as a failsafe for a runaway temperature condition (having the heater itself control the temperature, and hoping this unit would simply turn it off in a runaway condition). This unit and its parameters and alarms are not designed for that. I use it by cranking my heaters up to around 80° - a temperature my tank should never see. Then I let this temperature controller handle it at a more reasonable temperature of 74 to 75°. So even if this unit was to fail “on” somehow (basically impossible), the upstream heaters would still only have a potential to heat up the tank to 80° until their own thermostats would trip off. So it’s basically a triple failsafe at that point.I’m using this with the jinvoo smart app. I think there are a few other apps it will work with. But it paired up right away, and I have many other Jinvoo smart devices, including some of my Fishtank lights, on the same app (on a separate vlan of course!).Last point others have also hit on, make sure the two temperature probes are located close to each other. The point of them is to be redundant at the same point of reference. So if you spread them apart and have two different temperature readings it will assume a problem and halt operation.This little guy is pretty cool, and one of the most practical smart devices in my setup.

I purchased this about a month ago and wanted to wait a bit before writing a review to get familiarized with this temperature controller.I purchased this temperature controller along with 2 x 300 watt Eheim heaters to moderate the temperature of my pond during the winter months. Set up was easy. I took the contents out of the box, plugged in the controller and went through the process to get the controller registered with the Inkbird app on our WiFi. After getting that set up, I installed the controller unit beside my pond. And connected the heaters to the controller.This controller has 2 probes, however the controller averages the temperatures of both probes. If there’s a fault with any of the probes, the controller is supposed to alert of a malfunction. Fortunately, I haven’t encountered this (yet).I have my pond set between 60 (T1) and 70 (T2) in the app and the controller and heaters do a good job at maintaining the temperature and keeping it within this range.UPDATE: Almost two years outside on my patio and still going strong! The front of the unit is a bit yellow/brown from sun exposure, but it's still doing its thing! In addition to a testament to its longevity, I discovered another cool thing, this Inkbird controller is compatible with the Smart Life or Tuya app which works with TONS of smart devices including smart plugs, and other smart devices. I have several outdoor smart plugs on the Smart Life platform that control various components in my pond including pumps and lights. I've already tested this out in the app, but through Smart Life, I can have this Inkbird controller turn my pond pumps on and off based on the pond temperature even though they're plugged into a separate device. When the water temperature gets too cold, keeping the pumps on to help circulate the warm water near the heaters that are plugged into the Inkbird helps distribute the heat. Now this can be done automatically! The Inkbird can almost literally tell the pumps to turn on via Smart Life.
