IT DOES REPORT LIVE AND CONSTANTLY, UPDATING IN MERE SECONDS VIA LIVE VIEW IN THE APP, it is constantly updating and providing a realtime temperature in the app however it only logs the temperature and stores it once every 15 minutes. if it could be changed to log temperature every minute as an option that would be useful. again just a suggestion. its not really that helpful for anything, i just like to see everything going on. 3. upon changing any settings on the temperature controller it automaticly assumes that it needs to start either A cooling or B heating if the temperature isnt exactly what the set temperature is at. also sort of a non issue since once it reaches the temperature it reverts to normal operation, meaning the temperature differential, or the setting that adjusts how far from the set temperature it can change before enabling or disabling the cooling or heating system, once temperature is reached after setting a setting in the app or on the controller, works perfectly fine. however if you just want to adjust it so it 1 degree higher in the cooling differential, if you adjust it so it has a 5 degree cooling deviation instead of four, if the temperature is, lets say 78 instead of 75, although its only a 3 degree difference, since you just set the setting it automatically assumes that the temperature needs to be adjusted until it is at the correct temperature before starting operation normally. (just being clear) this is a setting i would want to have an adjustment on. like "restart device upon changing settings? yes or no" then if no is selected, when temperatures are changed if its still within range itll turn off. an example of how this would be useful is if you wanted to adjust the cooling differential higher so the cooling switch turns off, it will ironically turn it on upon making the change, which will immediately have the opposite effect as intended, until it reaches the set temperature, then will use the input settings and resume normal operation. this is the only issue i could see potentially being problematic if you have this placed somewhere with frequent power fluctuations, because when the device restarts it also does just this. checks the temperature and then goes "is it the exact set temperature? no because its off by .1? turn on the heating or cooling." again, just a small pet peeve, not a major issue, but this could be problematic as a UPS battery backup would likely not be able to power any real kind of cooling device and a high power relay of some sort would have to be used to allow power for any high consumption devices to be drawn from elsewhere and the temperature controller to be the only thing drawing power from the ups. that way when the power returns on the temperature sensor never turned off and does not restart. overall i woudl give 4.5 stars if i could because realisticly this is the only product on the market with these features in general, the features being wifi connectivity and the ability to just plug whatever you want into the controller and control both heating and cooling from the same device, as to save power. just my two cents :) Review: Simple to use (program) and does the job - Works great, easy to setup and use. configurable for 'F or 'C. I like the separate AC outlets on a dongle, but I wonder about the maximum load current capacity of the wiring. I've got a couple 200 watt grow lights and a 600/1500 watt space heater I run to grow tomatoes indoors during the winter. These would overload. I had been using a combo timer/switch with temperature control but after a few months this heavy load killed it. That worked for a while and then it's dinky power switch (relay) quit. So I found this Inkbird and ordered one. I'm sure it would do the job -for a while. As soon as I got it I noticed its quality. So I opened it up. It was an easy do. These days you can tell quality simply by seeing electronic components that have their markings still on the chips. -china removes these markings, but Taiwan and others do not. The Inkbird had all its markings and actually uses a rather powerful microprocessor to facilitate the control process. It remembers its settings when power off and that is an important feature. Very well. Since the last gadget died because of its relay failure, I decided to amp this up a bit. [pun intended] When your crop is dependent on not freezing to death -I hate failures. so.. The Inkbird uses a pair of relays -one for cooling and one for heating. These are separate from each other and rated for 15 amp 120 volt loading. Again, for a while... relays suffer horribly short lives when loaded to the max and cycling on/off many times as a thermostat will do. Then my epiphany.. A trick I use, is to construct a plug-in service box wired with 20 amp 120V grounded sockets, and with a solid-state relay, capable of at least 20 amps AC at 120V. I also use a 16 gage [or more] 3 wire power cord into this box. For extra credit, I use an expensive 'zero-crossing' type solid state switch (SSR). These run a bit hot when powering a 15+ Amp load so I add a big heat sink to the 'SSR' to help extend its life. This type of SSR uses a DC control (one/off) voltage between 3 and 35Vdc, so I add a small 12VDC wall-wart to switch the SSR, and let the Inkbird only power the wall-wart which in turn operates the SSR, which is very low wattage and thus a very light load on the relays inside the Inkbird. Note that this SSR box will operate a window AC as well. Add one of those Kill-A-Watt monitors and you can track the voltage, power and expense of your rig. ## Features - 【Easy to use】 Supports °C/°F display. - 【Dual relay】able to power refrigeration and heating equipment as conditions change. - 【Dual Display Window】Displays measured temperature and set temperature at the same time. - 【Buzzer Alarm】High and low temperature alarms are available when the temperature is over or the sensor experiences a malfunction. - 【Safety】Maximum output load: 1100 W(110 V).

Mine failed and is off by 4-6 degrees on average but could be off by more than 10 deg. at times which has killed my fishes. I was advised to buy a "thermal well" to protect the metal probe from premature failures. The replacement probes are 30% the cost of the whole unit and be ready to replace it an average of 1 to 1.5 years but as early as 5 months. I have a total of 6 units different models but same probes and 3 failures so far. Hope that helps. **Q: Can I make my deep freeze into a fridge if I plug this into it?** A: I've been running my deep freeze as a Keezer for well over a year now, utilizing this method with zero issues. It worked so well that I use a second one on an old fridge to be able to do temperature controlled fermentation. The cooling of the fridge and a homemade low power space heater keeps my fermentation within +/- 1 degree. Perfect for quality brews. **Q: Can I plug another heat belt into the cold outlet? I have one setup right now, would rather not buy another temp controller** A: You can not plug another heat source in the cold socket. When the set temp for heat is reached (plus the degrees of override you set) the cold plug is activated. Until then the cold plug it is dead (Off). You can use a multi outlet splitter for the heat plug side making sure their power requirements do not overload the units 10 amp capacity. You will not have any control of a second volume being heated. The one probe will just turn the heat outlet on and off and everything plugged in to it. It is either or, not both, allowing ten amps to be plugged into each as they will never be on simultaneously. **Q: Have a glass door cooler want to keep temp at 55 willthe probe wire conform to the door?** A: Depending on how many bends & how small the gap is. Probe wire is about 1/8" and flexible, sharp corners not recommended. Does cooler have another way to insert probe inside? Probe is 3/16 in diameter. Flat door seal should work fine. ## Customer Reviews ### ⭐⭐⭐⭐⭐ great product, works well, could use a few features *by T***. on September 13, 2019* great product. it works just as advertised. a lot of adjustments can be made, and the smartphone app can make all of them remotely, its super convenient. only a few minor things that i believe could be made better. 1. while the device WILL connect to google home and register as a device, google home has litterally no control over it, or ability to tell what the temperature is. since you can just use the inkbird app (or tuya app) this is really a nonissue. just a suggestion really. 2. the increments of time are quite broad. its not possible to have it log the temperature every minute in history, i believe it only logs every 15 minutes.

Works perfectly *by J***Y on April 5, 2026* Using for Kegerator temperature regulation, as my Insignia would initially only get down to about 39 to 42F. First, I found a set screw on the thermostat in back. Removed plastic housing around thermostat. Turned screw counter clockwise multiple times. This made it too cold, and rather than being careful and doing it slowly, figured it's best to have an actual regulator! Now I have the keg plugged into the regulatory, plugged into the wall. Set at 37 degrees with the probe sitting in cup of water on top of keg. 37 because at the bottom of the kegerator will likely be about 32 then, so the temp difference won't lead to freezing hopefully. Works great and easy. ## Frequently Bought Together - Inkbird ITC-308 Digital Temperature Controller 2-Stage Outlet Thermostat Heating and Cooling Mode Carboy Homebrew Fermenter Greenhouse Terrarium 110V 10A - Inkbird Humidity Controller IHC200 Humidistat Mushroom Greenhouse Pre Wired Outlet Dual Stage Humidifier Dehumidifier. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nz/products/31224934-itc-308](https://www.desertcart.nz/products/31224934-itc-308) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-04-23*
