In exchange for the low price, you have to pay a monthly maintenance fee. We continue to develop and improve your power meter firmware and the app, so you can view the monthly fee like any other software license… or your Netflix subscription… or gym membership. Same thing.

We continue working for you and you pay a small amount for that as long as you think you are getting something valuable in return.

With this maintenance fee subscription, you don’t have to upload data  and you can still use and get updates for your power meter.
