Just an unsolicited comment. Purchased the IoT Profiler which has provided valuable insight into our product development and firmware tweaks. But what is even more impressive and of great value has been the customer service. Had a hiccup with the first piece of hardware delivered (perhaps damaged in shipping), and without hesitation or shipping cost the device was replaced. Questions posed via email are answered within minutes 24x7. So, from a developer and manufacturer's perspective, can't ask for more. Thank you team. JS

Our first GUI release of the new year 2020. Ver 2.3.4 is now available for download. It has one minor bug fix for the battery model addition and reduced calibration time.

For some applications where the target device is connected to the main earth (ground), the non isolation of the power profiler may be a problem. It could pick-up noise and can cause small offsets in measurement. In order to solve this ground loop, we recommend to use a high speed USB isolator which runs at 480Mbps. We have tested a product named Hifime High-Speed USB Isolator and found to be working fine with the IOT Power Profiler. It provides isolated USB port which can be used with grounded loads with greater accuracy. https://hifimediy.com/high-speed-usb-isolator-480Mbps Note that any USB isolator would not work. It has to work at 480Mbps and should be able to provide at least 200mA to the power profiler. Most USB isolators out in the market work only at 12Mbps and not at the high speed.
