EL-WiFi Data Loggers

What is the difference between the sample rate and the transmission rate?

The sample rate sets how often the WiFi device records a reading. The transmission rate sets how often the WiFi device transmits this information to the EasyLog Cloud. Choosing the right sample and transmission rate for your specific needs is vital to ensure that you maximise battery life. Every application is different so we have made the system as flexible as possible.

Settings will not save. What can I do?

View page 8 of Help Guide 3: Network requirements and settings document for more information.

How can I reset my sensor?

The device can be reset by holding the button for 10 seconds. Release the button when RST appears on screen. The device will retain all settings but will lose any data that had not been transferred to the EasyLog Cloud. It will continue to be connected to the account it was set-up with and will simply start a new recording session.

If necessary, a full factory reset can also be performed by holding the button for 20 seconds until FArS appears on screen. Doing this will return the device to the factory state, deleting all settings and clearing any remaining data. The device will no longer be connected to any network or EasyLog Cloud account.

IT IS RECOMMENDED THAT YOU ARCHIVE THE DEVICE ON YOUR EASYLOG CLOUD DEVICES PAGE BEFORE UNDERTAKING A FACTORY RESET.

What does it mean when the MAX, MIN and battery symbol are all displayed on the LCD at the same time?

This is displayed if the device is charging, and the temperature of the battery is above 40°C.  For safety, the device will stop charging until the temperature has returned to a safe level.

How do I turn the sensor off?

The sensor cannot physically be switched off; it will remain on permanently until the battery runs out.

How do I know if my router is 802.11b compatible?

All WiFi AP/Routers are 802.11 compatible and there are currently five standards in general use; a, b, g, n and ac. To find out what type of router you have, you may need to refer to your AP/Router user manual or contact your Internet Service Provider or IT Department.

The sensor will not connect to the PC via USB. What shall I do?

  1. Unplug the USB cable and reconnect
  2. Sometimes USB cables can fail if possible try another USB cable
  3. There may be a difference between the USB ports on your PC, try another USB port
  4. Restart the PC and reopen the WiFi Sensor Software. 

If the above does not resolve the problem please try the steps below:

  1. Do a soft reset of the sensor by holding the button for 10 seconds (Unit flashes 'LOW' battery symbol or shows 'rSt')
  2. Factory reset the sensor by holding the button in for 20 seconds (Unit shows FArS)
  3. Unplug any unnecessary USB devices

If the above does not resolve the problem please try these next steps:

  1. Check device appears in Device Manager You should see a COM Port labelled STMicroelectronics. Check that it is not disabled and showing as working normally.
  2. If the device is listed but not working please reinstall the software.
  3. Change the COM port number. To change the COM port go to Control Panel, Hardware and Sound, Device Manager, Ports, STMicroelectronics Virtual COM port, Port Settings, Advanced and then select a COM port from the drop-down menu that is not in use. Windows Vista and XP may differ.

If you have tried all of the above but the sensor is still not recognised by your PC please contact us on 01425 651111 or email at support@filesthrutheair.com

Will the device work with a VPN (Virtual Private Network)?

This is technically possible, provided that the VPN can allow the device internet access via TCP port 14354.

What affects the battery life of my EL-WiFi sensor?

1) Transmission period
2) WiFi encryption method
3) WiFi encryption key rotation frequency (determined by the router)
4) Signal strength between router and WiFi device
5) Presence, volume and type of WiFi traffic from other devices
6) Sample rate
7) Operating temperature

The WiFi icon on my sensor is flashing, what does this mean?

This means that the sensor is not connected to the EasyLog Cloud. Check your network connections first and then make sure that the sensor is within range of the access point or WiFi router. To save battery power, the sensor may be in sleep mode for up to 30 minutes and will then look for a connection again. No data is lost while the sensor is temporarily not connected. Once connection is resumed all data will be synchronised with the EasyLog Cloud.

How do I force a transmission from my EL-WiFi device?

When the sensor is displaying the main reading screen on the LCD, press the button on the front four times. The MAX, MIN and Signal Strength screens will be quickly displayed. The device will try to transmit its latest data immediately, regardless of the transmission rate setting.

I have connected the device to my PC using the USB cable, but the software does not see it. What should I do?

You can try any or all of these steps to help with this problem:

1) Remove the USB cable and re-insert.
2) Restart the software.
3) Missing Drivers. If this is the case please reinstall the software.
4) Factory reset the device by depressing the front button for approximately 20 secs until the LCD display reads 'FA5r', then release the button, it will then be fully factory reset. Do not be tempted to release when it gets to approximately 10 secs when the display will change to read 'r5t', make sure you keep the button fully depressed. We do get a lot of customers who release too early and only reset the device!

Why will my device not connect to the wireless network?

You can try any or all of these steps to help with this problem:

  1. Check that the password being entered is correct.
  2. Check that 802.11b is enabled on the access point or router.
  3. Ensure MAC filtering is not switched on in the access point or router. If it is switched on, only known devices will be able to connect to your router.
  4. Check that your network has an internet connection.
  5. Check that the sensor is in range of the router.
  6. Check to see if the router has the latest firmware.
  7. If the access point or router has WEP Encryption ensure that the HEX key is being entered rather than the password. You can find the HEX key in the internal settings of your access point or router. Alternatively, search the web for resources to help convert your password to a HEX key.
  8. Check that DHCP service is running. This allows the sensor device to be allocated an IP Address. Normally, the DHCP service runs on either your router or on a network server. Make sure that the configured DHCP IP address range allows the addition of new devices if not, then extend the range.
  9. If your wireless network uses WPA Enterprise, make sure that the correct authentication type is selected from the drop-down box. Only the types listed are supported.
  10. If your access point or router has a wireless mode setting, this must be set to ‘Mixed’, not ‘Greenfield’.
  11. Make sure that the SSID name does not contain spaces.

If the device battery runs out, will I lose all of my data?

The device will not take readings when there is no power but all readings it has taken prior to the loss of power will be synchronised.  Once recharged, the device will reconnect to the EasyLog Cloud, start a new recording session, and continue recording.

If using battery power you must set suitable sample and transmission rates as these will affect your battery life.  You can power the device from mains using a suitable USB power supply if fast transmission rates or long-term, uninterrupted logging is needed.

If there is a power outage, will I lose all my data?

As the device is battery powered, it will always continue recording at the sample rate you have set.  If a power outage occurs, the device will continue to attempt to connect to your network until power returns and the access point or router becomes available again. The device then synchronises all remaining data with the EasyLog Cloud. No data is lost.

What battery life can I expect from my EL-WiFi device?

There are a number of factors which can significantly affect the battery life of the sensor including; transmission period, WiFi encryption method, WiFi encryption key rotation frequency (determined by the Access Point or router), signal strength between access point or router and sensor device, presence volume and type of WiFi traffic from other devices, sample rate, and operating temperature. In our tests, we regularly achieve battery life in excess of six months with a transmission rate of one hour or more.

Below is a brief matrix of estimated battery life for a number of WiFi transmission period scenarios:

 Transmission Period  Typical Battery Life
 1 Minute  1 Month
 15 Minutes  3 Months
 1 Hour+  6 Months+

How do I charge the battery in my EL-WiFi device?

The sensor will arrive partly charged but ideally, you should charge it for 24 hours before use for optimum performance. The battery can be recharged via a PC, a USB +5V wall adapter, or a portable USB battery pack using the USB lead provided.

* Please note that due to the heat generated whilst charging, WiFi devices with an internal temperature sensor will indicate a temperature a few degrees above the ambient temperature. Once fully charged, this heat generation ceases and the sensor will eventually indicate the correct temperature.  This anomaly does not apply to data loggers with external temperature probes.

How long will it take to fully recharge my EL-WiFi device?

From a very low battery state, it can take up to eight hours to fully charge your sensor.  The battery status can be seen from the Devices page on the EasyLog Cloud.  The battery can be recharged via a PC, a USB +5V wall adapter, or a portable USB battery pack using the USB lead provided.

Can I permanently power my EL-WiFi device?

Yes, you can permanently power the sensor using a USB wall adapter or external battery pack (both available separately)

Please note that due to the heat generated whilst charging, WiFi devices with an internal temperature sensor will indicate a temperature a few degrees above the ambient temperature. Once fully charged, this heat generation ceases and the sensor will eventually indicate the correct temperature. This anomaly does not apply to data loggers with external temperature probes.

How do I update my EL-WiFi device?

The WiFi devices contain program code that runs internally, often referred to as firmware. You can update the firmware via the WiFi Sensor Software (v1.40.03 onwards) by clicking on the green ‘Advanced Tools' icon and then clicking on the green 'Firmware Updater' icon. You’ll need to connect the device to the PC using the USB cable provided then follow the on-screen instructions to download and update the latest firmware versions.

To benefit from the latest improvements we recommend using the latest firmware releases for your devices. Depending on the previous firmware version, your device may be in a factory-reset condition following a firmware update, and will need to be connected to the Cloud. Any existing data for this device on the EasyLog Cloud will be archived for safekeeping.

EasyLog Cloud

Where can I find full FAQs for EasyLog Cloud?

I've forgotten my EasyLog Cloud password. How can I reset?

If you forget your password, please use the 'Forgotten Password' link on the 'Sign In' screen, or click here. This will ask for your email address and will send you a link to reset your password.

Is there a way to reduce the number of email alerts I receive?

You can tailor the emails you receive in a few ways:

1)  When setting up email alerts in the Change Device Settings page, you can freely select which events cause emails to be sent. Perhaps you are only interested in the measured alarm levels and can un-tick some other options you don’t need.

2)  When you set-up an alarm level, you can delay the onset of the alarm by a selectable period of time. For example, when monitoring the temperature of a chiller, you might not need to know if the temperature exceeds the alarm level briefly (when someone opens and closes the door, for instance), but you do need to know if someone leaves the door open. When using dual channel sensor devices, alarm delay is independently settable for each channel.

3)  Have you set an alarm level that is too low or high? Every time a device goes into or out of alarm, an email is sent. If your device is constantly “chattering” around the alarm level, you will receive more emails.

4)  To reduce email traffic further, you can choose to reduce the number of alerts, by periodically summarising them into a single email. You can enable this option, and specify how often the summary emails are sent, in My Settings.

Is there a limit to the maximum size of a session?

Sessions have been limited to a maximum of 300,000 readings to avoid problems associated with graphing very large data sets. This limit is equivalent to just over 1 month at the fastest sample rate (10 seconds). One year of logging can be achieved with sample rates of 2 minutes and above.

EL-USB Data Loggers

Where can I find the EL-USB data logger software?

The software for EL-USB data loggers is free of charge and can be downloaded via the 'Support' page, or by clicking here.

Do you issue software updates?

We aim to keep up-to-date with the latest Windows variants. New versions are also released when new features are added to the software. Check our 'Support' page for latest versions.

What do I need to set up an EL-USB data logger?

EL-USB data loggers can be set up using a PC, laptop or an EL-DATAPAD. The EL-DATAPAD* is a handheld device which allows the configuration and download of EL-USB temperature and temperature & humidity data loggers on-the-spot rather than removing the logger from the environment being measured and taking it to a PC.

* The EL-DATAPAD is sold separately.

Is the EasyLog software compatible with Mac, Linux or Unix?

Unfortunately, we do not offer an EasyLog software which is compatible with Mac, Linux or Unix at this time. 

If you do not have access to a Windows PC or laptop, temperature and temperature & humidity EL-USB data loggers can be set up and managed using the EL-DATAPAD, eliminating the need to use a computer (for these logger types only).

Do I need to reset the data logger after each time I download the data to PC?

The data logger will need to be reset after downloading data from the data logger. Once data has been downloaded, click the "Set up and start USB data logger" button, which will take you through the setup process again. The software would have remembered your previous settings, allowing for quick setup, or you can alter the settings for a new data logging session.

How many data loggers can be set up on PC?

You can set up as many EL-USB data loggers as you like on a PC, but you can only connect one data logger at one time via USB port. 

What does '---' mean on the LCD screen of my EL-USB LCD data logger?

'---' on the LCD display of your data logger indicates that the data logger is not logging.

What does 'PS' mean on the LCD screen of my EL-USB LCD data logger?

'PS' indicates that the data logger is in 'Push-to-Start' mode. Pressing the button will start the data logging session. 

What does 'dS' mean on the LCD screen of my EL-USB LCD data logger?

'dS' indicates that the data logger is in 'Delayed Start' mode. The data logger will start logging at the time specified when the data logger was set up. 

Can I set up an EL-USB data logger to start logging at a date/time in the future?

At the end of the setup wizard, you can choose a start time and date from the drop-down calendar, and the data logger can be left to start logging at the specified time. 

How do I stop the data logger from logging and turn off the data logger? 

All EL-USB data loggers require connecting to a PC to stop logging. Removing the battery will also stop the data logger from logging, and any data on the logger will be stored on the device until it is downloaded to PC. There is no 'Power Off' button. 

Can I export the data to Excel? 

Within the graphing section of the software, there is an Excel button. Click this to transfer the data from the software to Excel. An Excel graph will be generated and the raw data will be copied into a second tab in Excel. 

Will my EL-USB data logger work outside? 

Most EL-USB data loggers have an IP rating that is suitable for outdoor use. Check the appropriate model's datasheet for this information. 

What do the flashing LEDs mean when I connect my EL-USB data logger to a PC?

If the LEDs flash sequentially it may indicate that there is a problem with the battery. This could either be a flat battery, which should be replaced, or a battery where a passivation layer has formed. Leaving the data logger connected to a PC for about 30 seconds will remove this layer. After this, remove and reinstall the batteries to reset the data logger. 

If the LEDs are sequentially flashing after disconnecting the data logger from the PC, the logging session won't start as there is still an issue with the battery. Check the battery condition and repeat the setup procedure. 

What is a battery passivation layer?

If left unused for extended periods of time lithium metal batteries, including those used in the EasyLog range of data loggers, naturally form a non-conductive internal layer - a passivation layer - preventing them from self-discharge and effectively increasing their shelf life. When first installed in the data logger, this may cause a momentary drop in the battery voltage (the Transient Minimum Voltage) as the internal layer is broken down, resulting in the data logger resetting. Inserting the batteries in the data logger and leaving it connected to a PC for about 30 seconds will remove this layer. After this, remove and re-install the batteries to reset the data logger. Overall battery life will not be affected.

Which type of battery should I use in my EL-USB data logger?

For most USB loggers you need 1 x BAT 3V6 1/2AA. 

The loggers that need a different battery are listed below:

  • EL-USB-LITE

You will need 1 x CR1620 lithium coin cell. 

  • EL-USB-1-PRO

You will need 1 x BAT 3V6 2/3AA.

  • EL-USB-1-RCG

The EL-USB-1-RCG features a non-replaceable, rechargeable battery. If you think the battery has gone flat, connect the logger to a PC for up to five hours.

  • EL-USB-ACT

This product uses 2 x standard AA batteries.

How long will the battery last in my EL-USB data logger?

The battery life will depend on the model type and the logging settings that you selected during set-up. Full battery and other specifications can be found on the relevant model's datasheet. 

How do I replace the battery in my EL-USB data logger?
