Inkbird ITC-306A WiFi Temperature Controller, Wi-Fi Aquarium Thermostat Heater Controller 120V~1200W Temperature Control with Two Probes only for Heater Aquarium Breeding Reptiles Hatching.

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.

This heater controller is an excellent choice. I purchased it a few months ago to control my Eheim Thermocontrol e50, and I can confidently say that it has been trouble-free. Its WiFi connectivity has been a lifesaver when I’m not home but want to check on my tank’s temperature. I’ve also tested the alarms for too cold and too hot using ice and hot water, and both alarms are audible from the unit and my phone. They’re both very effective at grabbing your attention. Additionally, I’ve tested its durability, and it’s proven to be incredibly long-lasting. The value for money is also exceptional. It’s the perfect fit for my tank and has done an excellent job of keeping it between 80.9°F and 82.1°F.

Works perfectly. It takes several tries but it does connect to wifi. I keep a fan plugged in. Works great to cool my aquarium to the desired temperature. The led is easy to read. Fan turns off when it reaches the cool temp setting and turns on soon enough to keep the tank within 0.3 degrees of the high temperature. I am pleased with the purchase and would buy again.

Easy to use and is great

I have 5 of these total. The older, non wi-fi style I bought used about 2 years ago and it is still working great. The new units Do not work with 2.4G wifi, 5G was not available at the time of purchase. When they work they work well, after one tank crashed when teh house heat went out and my 50W heater couldn't keep up with the ambient air, I put 2 heaters in every tank, so this unit was great for that secure backup. However right about 1 year after purchase, 2 of the 4 new ones started malfunctioning, not controlling teh temp properly, alarming at all hours when there was no change in the tank, one of them fried BOTH heaters in my tank, but fortunately the temp probe still worked so I dropped in an new heater and am just using teh (expensive) digital temp probe right now. I'll keep the other units as long as they work, but will not buy any more of these.

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
