Riot device not working

I purchased the Riot device from Swift Electrical after they promised me that it would work perfectly with my system. Before buying, I made it clear that I have an old inverter that doesn’t support RJ45 or RJ12 ports, but they assured me it would still be compatible with the Hubble. However, nothing worked as promised. Their excuse was that they don’t typically sell these devices to others. There was no after-sales service or support whatsoever.
