InkbirdWireless Thermometer Humidity and Temperature Monitor, IBS-TH2 Freezer Thermometer Bluetooth Temperature Sensor Smart, with APP for Android and iOS (Temperature and Humidity Sensor)

It only took a few minutes to set up the app and configure it to work with home assistant. It's placed on the bottom of the freezer and is working great.

If you're looking for a temperature/humidity sensor for long term usage then guess what? This isn't it!! I've had this device for approximately a year and purchased it here on Amazon with the IBS-M1 wifi gateway so I could have connectivity to the device when away.There's no real way to determine if the device isn't functioning other than connectivity, no light etc. This isn't a terribly expensive device, but I had expectations it would last longer than a year or two.The mobile app developer also put out a new app and eliminated the old one. The new app doesn't have half of the functionality that the old app had in place, and this device doesn't even show up in the new app. What's worse is the app won't respect regional settings such as imperial measurements and there's no way to change it. Sorry (not sorry) I grew up and live in the United States, if you're going to force me to use metric you just as well make the entire app in a foreign language, since it can't be changed it's useless. If you like having historical data from the app, that's also gone!

I really like the accuracy as well as the speed of the updates from these devices. The downside to these as they go through batteries a LOT. I usually get about 2.5 to 3 weeks out of a set of batteries. I bought some amazon basics rechargeables and that's made me a lot happier with these as I just change the batteries out with the rechargeables so its not as expensive as they were when I first started using them. I have 3 of these devices, one outside and 2 in my freezers. I don't use their app at all, I have these devices added into my Home Assistant instance via some Shelly and ESPHome Bluetooth proxy's. In this setup I am happy with these devices and am very happy with having regular monitoring of my freezers.

Thought it died after about a year but after changing the batteries and waiting several minutes for the app, it finally connected.

This is a great product for dialing in the temperature and humidity of a particular area or room. We really think this is the way to go for expanding the level of data we can pull from our garden, using these gauges to extract meaningful details.This gauge took a bit to get running only because the instructions do not explicitly say that WiFi is required to pair the device. The instructions provided elude that only with Bluetooth enabled the device will pair with your phone using the Engbird app. This will fail to pair until your phone has connection to a wife source. At this point, it should connect no problem.Another user interface note to mention is that the initial setup of the device makes it seem as though your options are very limited concerning how you can have the gauge monitor certain humidity and temperature ranges. There are 6-7 profiles to choose from but they might not capture the range you are looking for. This is okay, just select one profile that is close to the range you are looking for and once selected a new window will pop up allowing to dial in the ranges to your desire.

I purchased the inkbird Bluetooth thermometer and humidity indicator as a new and unused product, and when my order got here the box it shipped in was perfectly fine and undamaged.The inkbird box inside, however, was a little different. Both tamper evident seals had been sliced and already had some coco coir on it along with some dirty fingerprints, and when I opened the box the manual and the thermometer itself also showed signs of being handled before by unwashed hands. This included fingerprints.From an integrity point of view, advertising an item as new and sending a customer a used and dirty product is a pretty foul way of doing business imo and from one business owner/gardener to another you get what you give and reap what you sow so, good luck to you on that. I understand it’s intended to get a little banged up and dirty, but if I wanted it to be like that when I got it I would have purchased a used one. This part of my review is about the principle behind these sorts of ethics and how something like that can have a direct impact on your business.As far as the product itself, once I put the batteries in it took a while to connect to my phone’s Bluetooth. I sat there for a good half hour with my phone right next to it, on top of it, beneath it, tilted towards it at a slight angle, at a -slightly- more slight angle, upside down, facing each other, facing away, you name it.Couldn’t get it to connect. Bluetooth was fully functioning and enabled, etc.I felt like Hansel in Zoolander when they can’t find the files “in the computer”. Like, WHY is this so difficult?? It shouldn’t be this difficult. Is it me? Is it the app? Is this a broken device? Did I get scammed?? Am I going to have to return this?? I just want a little thermometer to tell me how my greenhouse is doing!Ugh.I gave up and took a breath, came back to it one last time and laughingly said “watch it just mysteriously connect this last time” and somehow it did. Didn’t do anything different, it just decided to connect. So whatever, at least I have it connected now, and I got a bit of a laugh out of it, yeah?Well now onto the functionality itself. The readings it gives me are, for the most part, accurate enough. I don’t need it to have marksman precision, I just want to be able to check on my garden temperatures without having to drop what I’m doing and go find out, and I just need it reliable and close enough to see and know that my plants aren’t freezing or burning. The humidity indicator is a bit skewed though. But at least I know this and I can keep this in mind when I get the readings.All this to say, I would feel it would be more worth the money if I felt I was receiving the brand new product I initially paid for. I prefer buying secondhand/used and I don’t like buying brand new things if I can avoid it, but with devices like this I do buy new.I’m likely a one-off scenario, and I don’t usually go out of my way to write reviews like this, but I was really disappointed in the condition of the product I got. It was a little gift for myself and it was already tampered with? But hey, it does work.

I have some other units from INKBIRD that I’ve had some minor problems with and not been able to get Tech Support on. I have one of these in my refrigerator and one in my freezer in my travel trailer. I’m not here as often as I would like so I wanted these to tell me if I was having a problem with keeping things cold.These units go through batteries and 7 to 14 days. I’ve tried to get Tech Support, but they don’t seem to understand my question. The company appears to be based in China so maybe that’s the problem. As of today I do not recommend because I’m going through batteries every 7 to 14 days.
