HT1 Smart Temperature Sensor and Humidity Sensor - Bluetooth Thermometer and Hygrometer with App Monitoring - Indoor/Outdoor Temperature and Humidity Monitor for RV, Humidor, Fridge & More (1 Pack)

As a guitarist with over 30 years of experience, I’ve tried countless hygrometers to protect my instruments, but none compare to the SensorPush HT1. This device is a game-changer with its unparalleled precision and accuracy. It gives me complete confidence that my guitars are stored in optimal conditions, preserving their tone and longevity. I was so impressed that I purchased one for each of my guitars, and they’ve all performed flawlessly.The SensorPush HT1 is user-friendly, reliable, and delivers real-time data with remarkable consistency. Its compact design fits perfectly in guitar cases, and the app is intuitive, making it easy to monitor humidity levels on the go. For anyone debating whether to buy this hygrometer, let me save you the trouble—stop searching and get one. It’s simply the best on the market.I also want to give a heartfelt shoutout to Jonathan Cousins, the owner, who went above and beyond to assist me. His professionalism, kindness, and expertise helped me choose the perfect hygrometer for my needs. It’s rare to encounter such exceptional customer service, and it made my experience even more satisfying.If you care about your instruments as much as I do, the SensorPush HT1 is an absolute must-have. Highly recommended!

I have bought 30 of these over the past 6 years. Only 1 failed after several years. I have tried others that are cheaper but I keep coming back do to the reliability, battery life and auto updating. Cheaper units require a manual update which I commonly forgot, so I loose weeks of temperature history these sensors will auto update if I walk into Bluetooth range. They are great for monitoring freezers after power failures to warn if high temperatures. I used to ensure good temperatures in 7 freezers in recent tornado power failures. Battery changes are simple with plenty of warning time. Can archive history for years of comparisons for record cold or hot days.

This sensor was very easy to set up, except for setting the proper Android permissions for the app. That is not SensorPush's fault, it is Google's fault for allowing different Android phones to have wildly different Settings UIs and for letting them change all the time. The SensorPush part of the setup was super easy.To test one sensor, I put it in the small grow tent where I am growing lithops, directly alongside a Thermoworks Signals probe I use for monitoring temperature and the exhaust fan's temperature sensor. I had assumed the SensorPush sensor would be problematic because everyone says it is so sensitive to direct sunlight, so I figured it would be at least a little sensitive to a powerful grow light. But it performs almost exactly as advertised, only +/-1.4F different from the Signals readings. It does read both higher and lower than the Signals device, so I can't use the SensorPush calibration setting to adjust it (as I could if it were, say, consistently reading too high), but I don't care because it is performing to specs and good enough for my simple needs.I put a second sensor in a fridge that I have in our garage. I didn't bother to compare this one to a known-good device like the Thermoworks; my goal for this test was to see if I could get readings from the sensor when it was inside the fridge out in the garage. It turns out that as long as my phone is not at the far end of the house, it can get readings from the sensor. Since I am buying the SensorPush wifi gateway and the gateway will live close to the garage, I'm all set. The sensor did alert me when the temp in the fridge got too cold, so that is working as well.I will be putting 2 more sensors outside in 2 cold frames that I have ordered for my succulents so I can monitor them. My big concern with the cold frames is that they will get too hot before the auto-opening vents kick in. The SensorPush sensors should be able to alert me if that happens.And let me thank SensorPush for something else: intelligent UX. If I set my Thermoworks Signals device up with high and low temperature thresholds prior to placing its probe, and the probe senses the temp is outside that range, it IMMEDIATELY starts screaming at me and continues screaming at me until I can shut off the temperature alarm and place the probe e.g. in a roast I'm going to cook.When I set the high and low temps for a SensorPush probe, on the other hand, it was smart enough to say, "OK, the temp is outside the allowed range, but he just set the allowed range, so I'll wait until the temp goes into the allowed range and THEN start monitoring for it to go out of range again." This makes so much more sense. Here's how it worked with the sensor I put in the fridge:I set the low temp to 33F and the high temp to 40F. The sensor was in a 70F room. The Thermoworks would've been screaming at me already. But the SensorPush waited until I put the sensor inside the fridge and the temp registered between 33F and 40F to "arm" its alerts, so to speak. After a while it alerted me that the temp had gone below 33F. Perfect.I am happy with these sensors. If I had known there were higher-end models that were slightly more accurate, I probably would've sprung for those, but honestly the low-end model is good enough for my needs. Now I can retire the Signals device I've been using to monitor the grow tent and go back to using the Signals for cooking, and I'll have all of my temperature sensor readings and alerts in the single SensorPush app.

being in the beer business, probing walk-in cooler, and keeping temperature consistent is part of keeping a profitable pour. This probe allows us to run a week log to find hindering temperatures while a business is running. Employees leaving cooler doors open, wrongly timed defrosters, and so on. This probe has worked efficiently, we just hope we dont drop it in water/liquid since it is NOT water proof.

Easy setup, app works well, Bluetooth only is ok but better with the gateway.
