Swedish customers receiving our shipments via Postnord are mislead to think they have to pay customs fee and VAT....
We currently ship minimum once per week.
Non-Norwegian customers are invited to order from our store on Lectronz.com, a third party sales platform that handles national VAT to EU countries, using the EU IOSS system (for order values up to 150 EUR ex VAT).

Can Pow-U and Pow-K show energy produced from solar panels or wind turbines?
Yes, of course!
A Smart Energy Meter measures and counts separately:
- "Import" energy and power: When your installation consumes more power than it produces (net import from the grid).
- "Export" energy and power: When your installation produces more power than it consumes (net export to the grid).
To get the exported power displayed on the main page, go to Configuration/Meter and set the production capacity [kWp] of your installation. This figure is used to scale the power gauge:
When this setting is done, there will be two power gauges on the main page. One of them will always be zero, depending on whether the installation is currently importing or exporting energy.
The small number displayed is the total energy import/export since your installation was new.
Export power and energy is part of the MQTT payloads. Please consult https://github.com/gskjold/AmsToMqttBridge/wiki/Message-formats
