Short answer: Yes. HashWatcher is a free app for iPhone, Android and Mac that monitors the hardware in a home or solo mining setup. It shows live hashrate, chip temperatures, shares and best difficulty, and sends alerts when a miner runs hot or goes offline. It is not a pool and not a miner. Which pool you point at, solo or shared, is a separate choice.
If you are running a Bitaxe, an Avalon Nano, or a few home ASICs pointed at a solo pool, this page covers what a monitoring app does for you and what it does not.
What a solo mining app actually does
Solo mining means your miner works on its own block template through a solo pool or your own node, rather than splitting rewards with a large pool. The odds of finding a block with home hardware are small, and nothing about an app changes that. What an app can change is how well you know your hardware is doing its job.
HashWatcher sits on your phone or desktop and reads each miner on your network. For every device you get:
- Live hashrate with a short trend line, so a drop stands out
- Chip temperature and, where reported, VR temperature
- Power draw, efficiency and fan speed
- Pool URL and connection status
- Shares and best difficulty where the firmware reports them
- Uptime
For solo miners, best difficulty is the number people check most. HashWatcher shows it per miner and can notify you when a device sets a new best. If a miner ever reports a block found, you get that alert too.
How it works, part 1: local-first monitoring
HashWatcher talks to your miners directly over your home network. Tap Scan Network and it finds supported devices, or add them by IP. Your miner stats come from the devices themselves, not from a third-party cloud dashboard.
Supported hardware includes:
- Bitaxe and other AxeOS boards, including NerdQ-class devices on the same open API
- Braiins OS miners
- Canaan Avalon and Avalon Nano
- LuxOS and VNish firmware
Mixed fleets live in one list with totals at the top. Your Bitaxe on the desk and your Avalon in the closet show up side by side.
How it works, part 2: alerts and controls
You are not going to watch a dashboard all day, so alerts do most of the work.
Alerts
- Temperature, per miner. Set the chip temp you care about for each device.
- Offline or pool lost. Know when a miner stops hashing or drops its pool connection. For solo miners pointed at a single endpoint, this one matters.
- New best difficulty and block found. The moments solo miners care about.
Controls where firmware allows
Depending on the device, you can change fan speed or work modes, apply and test overclock tunes on AxeOS boards, and update pool settings from the app. That is handy if you want to move a miner between a solo pool and a shared pool without opening each miner's web page. The pool decision is still yours. HashWatcher just makes the change easier where the firmware supports it.
How it works, part 3: checking in away from home
On your Wi-Fi, HashWatcher works out of the box. Away from home, your phone cannot reach local miner IPs on its own. You have three options that skip port forwarding:
- HashWatcher Hub ($60). A small plug-in gateway for your home network. Setup in the app takes about a minute.
- Desktop Gateway (free). Use a Mac or Windows computer you already leave on 24/7.
- Braiins Deck. A desk display with the HashWatcher widget and remote access through Tailscale.
The remote monitoring page has the details.
Pool dashboard vs hardware monitor
Most solo pools have a web dashboard. It is worth keeping open. It just answers a different question.
| Pool web dashboard | HashWatcher | |
|---|---|---|
| What it sees | What reaches the pool: submitted shares, pool-side hashrate, best share | What happens on your hardware: temps, fans, power, local hashrate |
| Hot or failing miner | Shows up later as a hashrate dip, if at all | Temperature and offline alerts per device |
| Multiple pools | One dashboard per pool | One list, whatever each miner points at |
| Controls | None on your hardware | Fan, work mode, tunes and pool changes where supported |
| Where data comes from | The pool's servers | Your miners on your network |
The two work well together. The pool tells you what it is receiving. HashWatcher tells you why the number might have changed, whether that is a hot chip, a fan problem or a miner that dropped off Wi-Fi.
Frequently asked questions
Is HashWatcher a solo mining pool?
No. HashWatcher is a monitoring and control app. It does not mine, and it does not run a pool. You point your miners at whatever pool you choose, solo or shared, and HashWatcher watches the hardware.
Will a solo mining app help me find a block?
No app can raise your odds of finding a block. Odds come from your hashrate compared with the whole network. What HashWatcher does is help keep your miners online and healthy, so the hashrate you have is actually working.
Which miners does it work with?
Bitaxe and other AxeOS boards, including NerdQ-class devices, plus Braiins OS, Canaan Avalon and Nano, LuxOS and VNish. Most home solo setups fit in that list.
Can I check my solo miners when I am not home?
Yes, with HashWatcher Hub ($60), the free Desktop Gateway on an always-on computer, or Braiins Deck. None need port forwarding.
Is it free?
HashWatcher is free to download on iPhone, Android and Mac. Premium is optional at $2.99 a month, $19.99 a year, or $39.99 lifetime. The app is rated 4.9 stars, with more than 1,200 ratings across the App Store and Google Play.
