Analog 0 - 30V Add-on (Shelly Pill)

Took me ten minutes to wire it up, and the 30V range reads spot-on against my multimeter. The compact pill form factor fits neatly in the enclosure without any crowding.

Finally got around to installing it and the 0-30V range is spot on, reads my bench supply within a tenth of a volt. Took maybe ten minutes to calibrate in the app and now I can monitor my solar battery without guessing.

I was a bit nervous about wiring it up, but the terminals are clearly labeled and it took me under ten minutes. Now I can monitor my battery bank's voltage right from the app, which is exactly what I needed.
