Really nice, neat, little unit. A couple of things that would be useful would be: 1. An optional piece of curved plastic to fit over the top of the unit, to allow the cable to be hooked over it and stored when not in use. 2. Improve the app a little to include prices. The app seems to know my tariff, so could easily use costs as well as kW units. 3. Auto-email the energy use every day, to avoid the need to go and check in the app. 4. Include open charging sessions in the history. I know it's controversial, but when my car charge has finished but it's still plugged in, it's annoying it's not listed. Thanks!
