Description
The OM-EL-WIFI-TH wireless temperature/humidity data logger measures the temperature and humidity of the environment in which it is situated via internal sensors. The OM-EL-WIFI-TP (single channel) and OM-EL-WIFI-DTP-PLUS (dual channel) wireless temperature data loggers measures temperature via the included removable thermistor temperature probes. The OM-EL-WIFI-T wireless temperature data logger measures temperature via an internal sensor. The OM-EL-WIFI-TC (single channel) and OM-EL-WIFI-DTC (dual channel) wireless thermocouple input temperature data loggers accept a type J, K, T or N thermocouples. Data is transmitted wirelessly via a WiFi network to a PC and viewed using a free software package.During configuration the data logger will search for an existing wireless network while physically connected to the PC. It can then be placed anywhere within range of the network. If the data logger temporarily loses connectivity with the network, it will log readings until it is able to communicate again with the PC application (max 60 days at 10 second sample interval for OM-EL-WIFI-TH) (max 120 days at 10 second simple interval OM-EL-WIFI-TP, OM-EL-WIFI-T and OM-EL-WIFI-TC (max 30 days at 10 second sample interval for OM-EL-WIFI-DTC and OM-EL-WIFI-DTP-PLUS). The range of the data logger can be increased by using WiFi extenders. The probe on the OM-EL-WIFI-TP and OM-EL-WIFI-DTP-PLUS can be used in a wide range of temperature situations e.g. manufacturing processes, cold storage and hot storage.
The OM-EL-WIFI Series are low powered battery devices. When configured using typical sampling periods (e.g. once every 60 seconds) the data logger will operate for over one year. The battery can then be recharged via a PC or USB 5V wall adaptor using the USB lead provided. The battery is safely charged when the unit is operating between 0 to 40°C (32 to 104°F). It is protected against charging outside this temperature range. Data logger readings may be inaccurate during battery charging.
With the OM-EL-WIFI Series the software installed on the PC will allow set-up, data logging and data review. Set-up features will include data logger name, °C/°F, sample rate, and high/low alarms. Once configured, historic data can be viewed via the graphing tool or exported into Excel. This software is available for free from OMEGA. The OM-EL-WIFI-TP (single channel) and OM-EL-WIFI-DTP-PLUS (dual channel) wireless temperature data loggers are supplied with removable thermistor temperature probes. The probe can be attached to a wall or other flat surface using the included mounting bracket (probe clips into the bracket).

Does the job
Bought this to remotely monitor temperature in a residence. Does essentially what I need it to. Would really like to see an API so I can integrate it into my network more fully. Don't really like to have this information in the cloud.

Troublesome but Great
We had to purchase a new, used computer as our existing ones operated on windows 10, and this product is only compatible with windows 7. This caused quite a bit of frustration, but after spending more money on a computer we did get your monitor working and it is doing the job we wanted it to do.
So, having said all that, please let us know when you have a windows 10 version of the product,
Thanks,
Steven Baker

Wi-Fi Functionality misleading
This unit is supposedly designed for use on a Wi-Fi network, but it doesn't work with the most up to date WiFi encryption (WPA2). Omega happily handled the return, but this is obviously a significant design limitation of this device that should be stated upfront.

Troublesome, Not Trustworthy, Fails Calibration
I've had two of these units, the OM-EL-WIFI-TH and the TH+. They're easy to use and have a nice display. You have to pay $8/mo to monitor them, but the software is nice and has great features.
However, if you need a unit that's calibrated this isn't for you. Initial calibration was great. Year 2: failed calibration until they charged it all the way and then it passed. Year 3: failed calibration regardless if it was fully charged or not.
Don't buy this if calibration accuracy is important to you.

Excellent Device for Loggin Data, bad connection
I bought this data logger to record the temperatures of the freezer and refrigerator at my company. The set up is easy and the logger pages are great but the device does not stay synced with the PC and would never set up on the cloud. The customer support was great, which attempted to assist me with the issues through a couple of weeks of trouble shooting. Unfortunately I could not resolve these issues. The set up on the PC go through the setup great and the device connects to the network as well as sets up the computer but after a few data downloads by the device it looses connection and cannot reestablish the connection to the network. I get the blinking antenna of death. As for the cloud, I do get through the connection to the Newark but the device continues to fail in the final setup so I never did get the device linked to the cloud.
Bottom line, the logging portion of the device is great but the connection side needs work. I will set my calendar reminder to download the data by way of USB every month to retain for records. So do not purchase this device if you would like a wireless data logger because it flat out does not operate properly, which I'm sure there are cheaper data loggers out there that just record with no WiFi or just network wired connection.

Poor Very Inaccurate RH% in Controlled Enviorment
Have used these for 8 years. Some from a few years back are starting to loose the ability to connect to WIFI. Ordered replacement. The new item arrived defective reading +5% lower than actual RH%. Returned product for warranty. After 1 1/2 months product was "verified" out of spec and a replacement was issued. Opened up the replacement......replacement was also out of spec. Customer service unable to provide timely help. Received a bill for the warranty shipping today as well.

Disappointing.
I purchased this temperature logger to replace an old paper chart recorder when I became head of our quality control department. I chose Omega (this unit is rebranded and offered by several companies) because I've used and trusted their products for many years. I've either been fortunate up until now, or Omega has significantly lowered their standards because this is absolute trash. Very tedious to set up on Wi-Fi, and if your company has any security protocols (which, I would imagine most corporations do) forget about setting it up on any kind of network. So, I decided to suck it up and just connect through USB. Now it is having issues simply installing on the PC. I updated the software AND firmware (which is not surprisingly through a third party) and still no luck. Basically I have a $300 digital thermometer.

Nice device
The temperature and humidity device is a nice device and quality product

My WiFi network has many VLANs w/ different subnet. Devices are randomly placed in VLAN pools. Do the devices it have to all be on the same VLAN/Subnet in order to function?
Hello
The devices do need to be on the same VLAN/Subnet with the computer you want to communicate with in order to function.

A previous question asked about the amount of time needed to acclimate or get to full accuracy. After these sensors have "acclimated", will they be sensitive enough to monitor small changes(0-2%) over a period of seconds/minutes?
Hello Zach
The unit runs via a WiFi connection, it is limited to the speed of the network. Reading intervals are as fast as one every ten minutes, as slow as one every ten hours, the resolution for humidity is 1% and for temperature is 0.1

Which thermometer would respond more quickly, the OM-EL-WiFi-TP or the OM-EL-WiFi-TC, and how long would it take to get a stable reading?
Hello Allan, response time is at least 60 minutes before your readings are at full accuracy.

Does this require a constant wifi connection? Or can it store measurements internally for them to be uploaded later, once a wifi or bluetooth connection is re-established? Planning to use somewhere that may not have wifi available.
Thank you for your question. It does not need constant WIFI connection. If you close the software the unit will go into sleep mode but continue to log data.

Do the units make noise? Is there an audible alarm?
Thank you for your question. The unit alone only has visual alarm indication. If you require audible than you need to purchase OM-EL-WIFI-ALERT. https://www.omega.com/en-us/data-acquisition/data-loggers/ethernet-and-wireless-data-logging/om-el-wifi-alert-alarm/p/OM-EL-WIFI-ALERT
