Three tips to save batteries in your WiFi data loggers<\/strong><\/h3>\n\n\n\n

Tip 1.<\/strong> If your Saveris 2 or testo 160 logger<\/strong> is forced to search for WiFi networks that sometimes “don’t exist”, the batteries can run out unnecessarily fast. One solution to the problem of unreliable WiFi networks is to set the maximum interval (1 day) for transferring measurement data to the cloud service. <\/p>\n\n\n\n

If you have made the maximum setting above, but have no WiFi network at all, you can connect the WiFi logger using a so-called “Hotspot” or “Internet sharing” from a mobile phone. <\/p>\n\n\n\n

Instructions for transferring with Hotspot:<\/strong><\/p>\n\n\n\n

When it is time to read\/transfer the measurement data, the Hotspot is started on the phone. Then press the refresh button on the logger to transfer the measurement data to the user account in the cloud. This can be done at any time and the result of the transfer can be easily checked directly in the mobile phone by logging in to the cloud service. <\/p>\n\n\n\n

Tip 2.<\/strong> Choose the right number of channels<\/strong>. The more channels are activated, the more memory is used. Frequent measurement intervals fill the memory and shorten the available logging time. With many channels activated and frequent logging, you need to “refuel” the logger more often via WiFi or Hotspot. <\/p>\n\n\n\n

In the example in the screenshot below, ppm CO2<\/strong>, Temperature<\/strong> and Relative Humidity<\/strong> are enabled in a testo 160 IAQ. This is easily changed with the buttons on the right. Red button deactivates the channel and green button activates it. ATTENTION! This can only be done in the Advanced cloud account.<\/p>\n\n\n\n

Tip 3<\/strong>: Finally, you can use a power supply unit if there is a power outlet near the measurement site. With such a solution, it is ultimately the memory capacity of the data logger that determines how often it needs to be read out. <\/p>\n<\/div>\n\n\n\n
