I think helium hotspots should be compatible with gotenna Mesh devices.
Both networks would benefit from this. The Gotenna Mesh network would benefit by gaining a bridge to the internet and more relay nodes. And the helium network could benefit if Gotenna Mesh relays were able to help pass traffic between helium hotspots that are not in range of each other.
This would be very useful for emergency communications.
Both devices operate on 900mhz and at very slow baud rates. Compatibility might be possible if both companies worked together to update their firmware & software to be compatible.
If you compare the helium network map to the Gotenna Mesh map it’s obvious how they could really help fill in the coverage map: https://imeshyou.gotennamesh.com/
