Question Answer
Will my wired SmartQ sensors work with your new data loggers? Yes, the wired SmartQ sensors have been in production since January 2000 and will work with our current data loggers, which are the V-Hub and V-Log range of data loggers.
Can I make my current SmartQ sensors Bluetooth? Yes, if you purchase or have a V-Hub or V-Log data logger with Bluetooth, you can plug your wired SmartQ sensors into this to make them Bluetooth. Please note: The V-Hub data logger is USB and Bluetooth as standard. The V-Log data loggers have USB, but the Bluetooth is an optional extra.
I have an old Data Harvest data logger and it has stopped working. Can you fix it? If the data logger is older than 7 years, then it is beyond economical repair. However, you may be able to make it work by charging it for at least 1 hour, and/or performing a hard reset of the data logger; if this is available, it will tell you how to do this on the label on the base of the data logger.
What is the main difference between the V-Hub and V-Log data loggers? V-Hub data loggers
https://store.data-harvest.co.uk/v-hub-sensor-link The V-Hub range of data loggers must be connected to a device (PC, Phone, or tablet etc) to work; it is not a stand-alone data logger.

V-Log data loggers
https://store.data-harvest.co.uk/v-log The V-Log range of data loggers will work as stand-alone data loggers, and you can see the readings in a digital format, but to see them as a graph and analyse the readings you do need a device (PC, Phone, or tablet etc).

When the V-Hub or V-Log range of data loggers are attached to a device, they work identically.
Question Answer
Is my Vu data logger Bluetooth? No, only the Vu+ data logger is Bluetooth.
Will the Vu and Vu+ data loggers work with the EasySense2 app? Yes, they will, but they may need a firmware update which can be found on the product pages on our website - www.data-harvest.co.uk.
