The Base unit is the hub of an IoTaWatt monitoring solution. This new version works the same as the V4 IoTaWatt, but also adds additional jacks to natively connect up to three AC Voltage Reference transformers to facilitate direct reference three-phase. Another significant improvement is the use of a new enclosure with integrated wall mount.

    Loved it so much I bought a second one. I have an electric heat in my house and live in the cold northeast so knowing when and how my power is being used is important.

    If you’re comparing Iotawatt to other units out there, please take into account the support on the forums, it is top notch. Cannot say enough good things about it and a special thanks to @overeasy!

    I just received my IoTaWatt yesterday and hooked it up last night. I recently moved from a townhouse to a much larger house and this device has helped me learn the usage patterns of my 2 AC units, well pump, pool pump, and other devices. It has only been a day, so I’m excited to see things over time!

    Thanks for building a product that works well, and allows us to tinker and adapt!

    My only problem is that I may need another one to monitor more connections. I guess that’s a good problem to have!
