I just bought two SensorPush humidity sensors, and they work great. I have one in my favorite guitar case; it not only shows current level of humidity, but notes trends in moisture and temperature. The other is in my house.. My guitar means a lot to me, and even though this is expensive, it does just what I need. I don't live in a particularly dry climate, so I have no need to add moisture to the inside of my case. If it trends towards being dry, I crack open the case. There is a sea breeze here every night, so I'm blessed to be living in West LA. This sensor works off Bluetooth, so it only has about 75 feet of range. I think there is a wireless gateway available for monitoring from a distance .. and update! . They agree with each other and certainly are suiting my purpose! Read more
After loosing two freezers full of food, I decided I needed a sensor that would work in a freezer in the bay of my motor home. After having two different ones that worked on a freezer and refrigerator, different brands, and not working underneath in a compartment, I decided to try the Sensor Push. Amazing! I am not a technocrat, and having read some of the review about lack of documentation, I went for it. Received in one day, opened the box, unpacked it, looked at the documentation ... yep, 4 pictures. Picture 1 Smart phone with ICON for play store and ICON for app store. Simple. Opened Samsung Galaxy S10 and downloaded and installed the app for Sensor Plus. Picture didn't say Sensor Plus, but after experience with 300 plus other apps, it is normal to push the mic button and say the name of what you have in your hand. Sensor Plus! Nice. Downloaded and installed in seconds, which looked like the second picture. 3 picture looked easy enough ... answer yes to allow location and turn on bluetooth. Picture 4 ... this is the hard part, a picture of the sensor appeared on-screen and said to place the sensor over the picture. Just like that we are hooked up and connected to blue tooth. From there, no more pictures in the booklet. But, looking at the phone the screen showed the name of the sensor (I changed it to represent the location it would be used), next temperature with a little line with MIN and MAX, with an option for an alert. I want to know when the freezer changes from it's normal 0 degrees to 15 degrees, which allows me time to pull off the road and open the compartment and take investigate why the freezer has changed, before things start thawing above 32 degrees. Same option for humidity, which I skipped quickly by, and then options to calibrate temperature and humidity. They were already at room temp, so until I found an oven or other thermometer to use to calibrate, I left factory temps alone. Hit the done sign, and placed the sensor in the freezer. Waited and watch the temperature of the sensor start to drop. Closed freezer tightly, closed the compartment, and took a seat outside with no metal around about 20 feet away. Neat, Hit the name of the sensor and two graphs ... one for temperature and one for humidity. Both falling as the sensor started getting cold. Watching over time, I can see where the temperature starts to rise, and then the compressor kicks back in and the temperature starts to drop one again. Would I buy one again! Of course, now the wife wants one inside the refrigerator as well. Since we normally have wifi when traveling, I ordered one more sensor for the refrigerator and the gateway sensor, so when we stop and leave the coach unattended, we will know if any issues develop. Great product and I expect the second sensor and the gateway to be of the same high quality standard. Will update if any issues. Batteries ... should last 1 - 2 years under normal warm conditions, so since the sensors will be refrigerated and frozen, I ordered a 5 pack of CR2477s for insurance. Amazon will ship anywhere we go, but until we find out exactly how long the last under extreme conditions, I'll carry enough to get me to the next required battery change and order more. UPDATE: Bought second sensor and G1 Gateway. This was too easy to hook up. 11 days and no more lost food. All components work well together and with the Gateway, food temps can be monitored while away. So far battery in sensor has dropped to 2.7v in 11 days, this is definitely in extremely cold freezer. Gateway is 20 feet away and monitoring two sensors without issue. Will buy another set for the house. These work well in a motor home surrounded by metal and all kinds of electronic components.

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. Read more
Rugged (used them outdoors, although shield from rain). Seem accurate (when eyeballed with liquid thermometer) Battery lasts at least a year. Wish the range was longer, expecially when I try to use them to monitor the interior temperature of a refrigerator -- being in a metal box like that means it needs to be pretty close to the gateway to work.
