## Description

The Wagner Meters Smart Logger is a Bluetooth Low Energy temperature and humidity data logger featuring the latest Bluetooth 4.0 technology. It can collect temperature and relative humidity readings from the surrounding environment and record it as historical data. The Smart Logger can store up to 12,000 temperature and relative humidity measurements over a period of up to 300 days. Any smartphone or smart device with Bluetooth 4.0 or above can download and install the accompanying app to monitor, record, and email the temperature and relative humidity of the environment as conditions change.

Review: Synopsis: Great user control of a temperature and humidity logging device with a quality Android app and the ability to export data to a PDF or CSV file. I have used a few different products that track humidity and temperature and that transmit through bluetooth to apps. They have all worked quite well, and some were less than $15. This unit was much more pricey, but with that you get a huge improvement in the options and level of control you have. With the cheaper units there was a polling rate of once per minute. That was it. You can set this unit to take a reading at any interval you choose. You can also set a high and low in temperature or humidity that will change that polling rate to a different setting of your choice. It will keep a log of all of those readings and a graph, and will allow you to export those readings to a PDF or CSV file format. If you have a need for that level of control and accurate polling of what is going on, this would be a good unit to have. You must be close enough to pull the information to your bluetooth enabled smart device, and need to download the information, as it isn't something that will give you a constant reading sent from a great distance. In other words, it's a logging unit and not an alarm of change in temperature or humidity. It does what it's meant to, and it does it well.
Review: Being able to track changes in temperature and relative humidity is very useful for a homeowner, a builder, the medical professions, archives and museums, a farmer, a gardener, or chef managing food storage, and anyone else who wants to monitor these critical values over time. Over how much time? Well, the CR2450 coin cell battery life for the sensor is rated at three years, and it can log 16,384 separate readings. Amazing! You can set the measurement intervals, from 1 second up to 136 years, according to the manual. No hints on how to manage the battery life over more than a century. The intervals are selected using the iPhone or Android app, connected to the logger via Bluetooth 5.0. Interval choices are seconds, minutes, hours, and days. But there is no problem entering values like 75 minutes, 36 hours, or thirty days. I'm not sure how many days are in 136 years, but I think I will want to check my data more often than that. Speaking of checking your data, the Smart Logger V2 will show your data graphically on your phone, and also prepare a PDF report with the data at the time intervals that you specify. You can use your phone to transfer this report to your computer. Suppose, for example, that you want your food storage facility to stay between 36˚ and 44˚. You might set your logger to record the data every hour. You would later be able to check whether the measured values were in this range each hour when you logged the data. But the logger has an additional important trick, for measuring in between your set intervals. You can set separate Alarm thresholds for high and low values of relative humidity and/or temperature. If the measured values exceed your thresholds at any time, the logger will record the time and data of that event. It can even send you a notification at that moment via email. If you wish, locations for each measurement can be recorded, mirroring your phone's location tracking, or set as a fixed address and location. The Smart Logger V2 can be password protected, or not. Another review here, from 2020, mentions having to enter the password every time the user wanted to check a reading. That may have been a feature of the V1 version, since this is not necessary on the V2 Logger that I have. The app tells me that I can monitor relative humidity from 0% to 100%, and temperature from -40˚F to 257˚F. Measurements can be set to Celsius, if you prefer. This is a five-star device held back by limited documentation and an app with some confusing features and modest user-friendliness. The User Manual is seven small-format pages, and I could find nothing more detailed on the website. The company has a few videos of roughly 2 minutes each, which provide little more information. On the plus side, they offer worldwide free phone support with fairly long hours. Two questions had me stumped, when I tried to start using the Smart Logger V2. I got the answers that I needed in a few minute phone call, from a friendly and knowledgeable support advisor. I hope that they improve their documentation soon, offering greater detail in print and in videos. After they do, I will raise my rating to five stars. It shouldn't be this hard to figure out how to use all the features that this logger offers. But once you figure it out, I suspect you will be very happy with the device.

I put this in a gun cabinet to monitor the temperature and humidity and track it over time. The graph shows how they change day by day to show treds. This lets me know when the Desiccant is losing effectiveness and when it will need to be recharged/dried out. No need to constantly monitor, it will alert me when the temperature or humidity gets out of the range I set. The app is very easy to use and the parameters are easy to set and change as needed. The temperature and humidity are accurate when I compare to some reference guages I know are accurate. This feel sliek a high quality commercial unit, not some cheap consumer grade items that will die in a year. The battery shoudl last 3 years. Probably less in a steel cabinet where the transmitter may have to work harder to get out. Time will tell. Even 1 year would be good. Wish someone would make one with an external antenna I could route outside the cabinet via wire.
