Great app/device (Zappi 2 in my case) but UX is a disaster. Aesthetics: a combination of neon on black & brushed steel make for poor accessibility. Controls are awkward and laggy: text entry fields disappear off the side of the screen & activity is blocked on network traffic. But worse, modes of operation and their presentation. 'Boost' seems to replace 'charge' arbitrarily. Desc. for Eco and Eco+ are identical and opaque. Great hardware fights against frustrating software.

Good to view the information about .the power used, generated, and sent back to the grid. However, I find it not very responsive to use having to repeatedly select icons to get that function to work. Also, I find that the information appears not to reflect what is happening on the eddi diverted. It either lags or leads?

Dashboard is great, sadly controls are not so great and lacking. Needs overhauled such as having do not heat schedules and more heat slots instead of just 4 per tank. Also I'm not sure if its session management or establishing connection with actually eddi but I find there to be a bit of latency sometimes when setting values and I need to try two or three times. Having a seasonal profile would be nice to swap in and out schedules spring Vs summer Vs autumn etc. I have a ton of ideas....
