- guappa 1y agoThe lifetime subscription :)
- codedokode 1y agoIt doesn't need to be lifetime, only as long as devices are supported. Also, electricity meters makers somehow solved this problem. I am sure a subscription won't be expensive if the device doesn't use too much data. Also the device maker can pay with collected data or advertisement.
