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 optimized 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 outdoor model and comes in an IP-67 rated enclosure. The Nebra Indoor HNT Hotspot Miner provides the same functionality in a more cost-effective enclosure.

Nebra Outdoor HNT Hotspot Miner (915MHz) Product Help and Resources

Core Skill: DIY

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.


Skill Level: Rookie - Basic hand tools are required and instructions will allow more freedom. You may need to make your own decisions on design. If sewing is required, it will be free-form.
See all skill levels

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

    No manual in box, no manual here, none on Nebra's website - except for a crowdsourced doc that doesn't cover the items shipped with the unit. Which antenna goes where? Why are there two, when all of the paperwork insists there's only one? Sparkfun is always so great with help. This unit is not working out like that. Any help would be appreciated.

      Yeah this was a pain! After opening the unit I confirmed that the top antenna is the longer (30cm) LoRa antenna, and the bottom one is the shorter WiFi antenna. It also needs to be powered from 48V PoE (I used a UniFi device). Finally the unit will appear to do absolutely nothing until you set up port forwarding for incoming TCP port 44158 to its local IP address. Leave it powered and mounted vertically and after a day you'll see some signs of life and mining will begin within 48 hours.

Easy to set up

Easy to set up and already making HNT

Batch 5 - received!

I haven't set this up yet, but I received mine today 9-22-2021 as a Batch 5 customer. Don't forget to order a separate power supply if you're not going to use PoE!

Unable to onboard

I'm unable to onboard and support has been abysmal. Initial response was quick but no response after I indicated that my issue wasn't resolved. It has been over a month since the last response.

Working great!

Took forever to come due to supply issues from Nebra and setup had some minor hiccups with the Bluetooth connection but overall it was easy to get going and worked without much trouble.

So far so good

Nearly three weeks in and it's been running using a POE connection just fine.
I ended up climbing back up and pulling the WiFi dongle and removing/capping (cap provided) the WiFi antenna since I'd never use it. Currently this results in an error on the diagnostics page but you can safely ignore.

Seems to be the 1-2 top miner in daily rewards in my small hilly city of 25 miners. Mechanically it seems pretty well built. We shall see what the longer term reliability will be. Thx

Already been claimed

Cannot add to wallet. When i try to add ot to nebra dashboard, it says , already claimed. Nebra does not respond

Worked for a while.

The delay was longer than expected (about 7 months of waiting) but does what it's supposed to. The miner wouldn't register for the first few days but that was probably a network issue. The miner looks rugged and well built. Antenna upgrade is almost mandatory because it's not worth running the miner without it now. I have an upgraded 8dbi antenna and I am making about 6 Hnt per month; about $114 at current price of $19. It's worth it because I don't plan on selling any Hnt tokens until about 4 or 5 years later. Many miners around me are making a ridiculously low reward of about 1 Hnt or less per month. I think this is because they are using the stock antenna.

Update: after running for about a month and a half, started having issues. I opened all the port forwarding that I was supposed to and restarted many times. However, the device is stuck on sync and shows offline on explorer. Not mining anything for over a week now.

Long wait, but worth it.

Took a long time to arrive, but it finally did, and is working great!

Making good money!

took awhile to get but seems like the wait was worth it easy set up and low running costs good buy! Fast shipping! (once in stock)

Some assembly issues. Easily resolved

Ordered 2 units.

First unit was fine, the second unit would not pair with bluetooth. I opened it and the Wi-Fi and BT dongles were in the wrong USB ports. Swapped them and all ended up okay.

Overall, great construction and all the parts needed to mount outside on a mast.
