GOQOTOMO Smart Temperature Controller Thermostat Heating and Cooling Mode for Homebrew Fermenter Greenhouse Terrarium 100-240VAC NTC Sensor Improved Version

Worked great for regulating my Anti Ice roof heat cable running thru my gutters last winter..on a covered porch outlet.

I use this to maintain my lithium batteries at a certain temperature in a heated environment. It controls a small heater that turns off and on at a preset temperature. It gives me sense of security protecting them

Today is day 45 since I received it and put it to use the warranty ran out 15 days ago.I use it to control a water heater set at 99°. Approximately a week ago it started randomly overheating keeping the heater turned on after it had passed the Off set point. Today I determined that it doesn't turn off the power supply even though the switch is off. (It continued to heat the water to 117°) Could cause a very dangerous overheat situation!

Nice product and well built. The sensor is removable making it easy transport your items if the sensor is taped down or attached.The display is sharp, easy to read and looks nice.

I bought this to control the pump on my DIY fermenter cooling system. I have a pan of RV antifreeze in the freezer part of the mini fridge with a 660gph pump in it. I drilled a 1 1/4" hole in the back of the fridge for the power cord and hoses. The antifreeze runs through 3/8" hose to the Temp Twister cooling coil in the fermenter and back through another 3/8" hose into the pan. After I got everything up and running and checked for leaks, I installed foam insulation around the hoses from the fermenter to the back of the fridge. I have less than $100 in this system including the controller.I have an Inkbird controlling my fermenting chamber (mini fridge). Actually, this temp controller is BETTER than the Inkbird! It has a self explanatory menu system, an easy setup or "PRO" setup option, unlike the Inkbird that uses a 2 letter system (which isn't hard to understand either). I have been running it for almost 3 days and it is working great! About the only thing I don't like is the temp probe coming out of the side of the main unit - it makes it less streamlined, but still doesn't get in the way. For half the price of a basic Inkbird controller, I would definitely buy another one of these!I will update on the controller after it proves itself for a while (or craps out on me, LOL).

I'm running 2 8" attic ventilation fans with this controller. So far, so good.Easy setup and operation. As advertised.

This device works ok but has no hysteresis or dead band. It can toggle rapidly between off and on which is not good for the temperature controller relays or my heating device. It does have a compressor delay function but it only applies to cooling mode.The menus are a bit hard to navigate and the controller doesn't work while in the menu.It's a shame because these would be simple things to fix in software. The device otherwise has a nice display and seems well made.

The temperature guage was way off! Could not get it to regulate at 200° which is well within the advertised range. Unfortunately I didn't get around to using it until after the return period had ended otherwise I'd have returned it. Buyer beware!
