Review: Simple with many options - Very easy setup either ethernet or wi-fi. Current readings and voltages match closely with my Fluke DMM. I am still experimenting with all the available features. The desktop and Android apps have both worked well. If you are interested in power consumption with the ability to control the load I would consider this item.
Review: Marine BEP Panel monitor - works great - Worked perfectly for monitoring a 50a 120/240V panel in a marine application
