One person builds Solmiro, and the same person answers your e-mail.

I started Solmiro because my own solar app showed me a number every day, but never whether it was a good one. Without knowing that day’s weather, 11 kWh can be an excellent day or a sign that part of the installation has stopped.

Solmiro answers that question every day: it works out what your roof should have produced in the weather over it, compares that with what it did produce, and stays silent unless the two drift apart.

Solmiro is a one-person company in the Netherlands, trading as UMeter.nl. When you write to support, you write to me.
