I don’t know that I really see the use case for home users outside of possibly in extremely dense urban areas. In order for the AP to make sense someone has to want to pay to stick an IoT device within range of it, which is probably not reflective of most homes. Also the ISP issue that knewman mentioned is a legit barrier to entry for board home adoption.
I do see some potential for this in certain industries, like manufacturing for example. Let’s say all of the computer users are in one small part of the building, but the rest of the building has IoT monitoring/HVAC/lighting equipment which needs wifi. In this case Helium could provide all the wifi they need while gradually chipping into its own cost via crypto mining. This probably only really works though if the client is going with one IoT vendor who themselves partners with Helium, otherwise why does the IoT vendor want to pay for internet that the client is already paying for?
It’s an interesting idea, and it may even prove viable in some industries, but I’d be surprised if it made a splash in the consumer/SMB space.
