Earn HNT cryptocurrency by mining and building coverage for The People’s Network using Nebra HNT Hotspot Miner. Anyone can join The People's Network and provide hundreds of square miles of wireless network coverage, while mining HNT on the Helium Blockchain just as Helium Hotspots do.

The People's Network runs on Helium LongFi™, a technology architecture that combines a leading wireless technology, LoRaWAN, and the Helium Blockchain. LongFi™ is optimised for miles of range, and long battery life for IoT devices.

The Nebra HNT Indoor Hotspot Miner earns the cryptocurrency HNT when devices connect., and for validating wireless coverage delivered by peers. Using a system called Proof-of-Coverage, Hotspot Miners earn more HNT when they're in range of other miners, but need to be at least 300 metres apart.

The Hotspot Miner sets up in minutes and has a smartphone app interface. This variation is the indoor model. The Nebra Outdoor HNT Hotspot Miner provides the same functionality in a rugged outdoor ready enclosure.

  • I’m wondering when they put the ordered in before April? Because If it was we should be getting this soon

  • Hope these get filled in due time. I saw the other day they had 168 incoming.

  • From Nebra web site: Batch 2 and 3 indoor pcb's are being assembled now. Batch 1 & 2 outdoor are finishing certification (FCC etc.) and expected to start shipping end of June. From #Nebra on Helium Discord, it sounds like all of batch 1 has been sent from the manufacturer to Nebra but not clear what they have received or sent along to their shipping company (other than the first 1000 units which went out a while ago).

  • So I ordered 15 of the pre ordered units. Was told that mine are in batch 2 according to the numbers from nebra. Some of you may be in batch 2 or all of you may be. I legit believe ordering from these guys when I did resulted me getting batch 2 units vs 4 or 5

  • So my order was put in on March 16th. How much longer til the ones before the 30th go out?

  • An email from them telling us where are they now in the production so to keep us updated will be helpful. Just like the rak hotspot. Also, wondering what is our place in the overall Nebra order??? In calchip(rak V2) website I can tell the production is still at 16118 (Panda) and I am at 20000+ so I'm still too far. But if we can also have a list of our order based on number here then that would be great.

    • I just hope they can fulfill these. Like you said, an update would be nice on their end. It may be that no one honestly knows, not even Nebra at this point, unfortunately.

  • Well yesterday it said it had 61 incoming but now it, 58?

Easy to set up

Interesting little box to get started on the Helium network. Easy to set up, though the included ethernet cable is a little short if you want to get best placement. That's easily replaced. It took a looong time for my hotspot to sync up and if you have a basic cable connection you'll probably be a relay (unless you can get a static IP addr and open firewall ports on your end). You will still get Helium coins, just not as many.

Only knock so far seems to be the antenna connector to the base. It's a little loose and wiggly, so the antenna can "flop" over if not positioned correctly. Doesn't affect the operation, but I've heard others point out the same.

Not working at 100%

Unit never completely powered up. I am working thru the issue with the customer support team. Eventually I will be operating at 100%


I received my miner and set it up as instructed, a piece of cake; however, BE SURE to follow the instruction not to damage your miner. Since this was my first miner, I was getting concerned when the first couple of days, all I saw was syncing. Then BAMM off to the races; my first token was mined 6/21, and as of noon 7/01, I have 94.55 rewards worth $1,173.35. My average day ranges from 0.80 - 2.65 rewards; however, on my first week anniversary, I harvested 80.17 in ONE 24HR PERIOD!

Wifi constantly disconnects

The wifi constantly disconnects, and it won't' stay online. Additionally, the unit shipped with the LongFi antenna module completely disconnected from the board, and rattling around the inside by the cable.

Wasn't even completely assembled

When I got my devices (I ordered 2) I found that the chipset had not been seated . The chipset was rattling around and I had to open the device to seat it. Simple enough but should not have been rattling around with the possibility of being damaged. It would have been impossible for it to become disconnected during shipping if properly seated, and both devices were like this. What is more, the antenna wire was not connected. This took a little more detective work as the connection point was not readily obvious. Again, both devices like this.

Getting them up and running was another chore. The app kept giving me bogus info and the devices would not connect wirelessly. I first had to use ethernet. I never was able to get my second miner set up at a second location I wanted and finally gave up. After back and forth with support I finally got both up and running but then outages caused me to lose the witnesses, etc. that had been established. More grief, and I had to keep giving support the same info. At one point they closed the ticket saying they considered the issue(s) resolved when they clearly were not.

We will see what all this gets me over time.
