Bobcat Diagnoser

Bobcat Diagnoser User Guide

Updated: 2 days ago

Many of you had been asking for a diagnostic tool that did not require bluetooth pairing and now here it is – The Bobcat Diagnoser allows you to get detailed information of your hotspot by simply entering the miner’s IP address in your web browser.

While a key feature of this diagnoser is that it does not require bluetooth, it is a local diagnoser, meaning that you be on the same LAN as the hotspot to access the web interface. The hotspot must be online to access the diagnoser, as the page will not load if your hotspot is offline. Lastly, while the diagnoser can be viewed using any browser, we recommend you use either Firefox or Chrome as they make JSON files very easy to read.

What Exactly Does this Diagnoser Do?

Along with simplifying the process for checking Bobcat’s firmware delivery, this diagnoser will consolidate valuable insights and key data related to your miner without requiring you to input a single query or having extensive coding knowledge. In accessing this diagnostic tool you will be able to:

  1. Prevent Hotspot Overheating w/ Alert Features
  2. Check Real Time Miner Syncing Information
  3. View Your Hotspot’s Current Helium and Bobcat Firmwares
  4. Identify Miner Issues (e.g. Miner Not Starting)

Understanding the Diagnoser Menu


  1. There are 2 temperature points on the CPU
  2. If the temperature is above 65°C , the diagnoser will show an ‘alert’ by changing the color of the temperature menu in the label.
  • Red = Above 70°C | Yellow = Between 65°C and 70°C | White = Below 65°C)

Sync Status (new feature added on 9/2/2021)

  1. Green = Synced. Gap is smaller than 10 blocks
  2. Yellow = Syncing. Gap is between 10 – 10,000 blocks
  3. Red = Syncing. More than 10,000 blocks behind
  4. This reflects the miner’s real-time syncing status and will therefore not always match what you see on the helium app, as the latter is often delayed.
  5. Selecting this menu item allows you to see the miner’s height and blockchain height. A fully synced miner will have a miner height that is larger than the blockchain height.

Miner (5s, Miner Slow Down)

This section takes around 5 seconds to load. Do not keep clicking if it’s loading, or the page will not load; Do not check this repeatedly, as it will slow down your miner

Most important info in this section:

  • “miner_alert”: – shows the miner (aka the docker process) has started; if instead, you see ‘red alert’ as below, it means the docker process has not started for some reason.
  • “ota_version”: “” – Shows the Bobcat Firmware Version; Check here to check against the latest firmware updates.
  • Image”: “…2021.08.2.0_GA” – shows the Helium Firmware Version
  • “height”: [ “24246 947944”,] – The first number is the election epoch and the second number is the block height of your miner. You just need to pay attention to the second number. You will be able to tell the true syncing status of your miner by checking this number against the block height number
  • nat_type – If this shows anything other than ‘none’, your hotspot may be relayed. Check here to see how you can remove the relay status.

Explorer, Onboarding, and Helium API

These are shortcut links to the Helium explorer page, the dewi onboarding API information, and the Helium API page for your hotspot.

Blockchain Height

Provides the true helium blockchain Height number.

Net Speed (30s, miner slow down)

You can test your network speed by selecting this menu item. The test takes about 30 seconds to complete and you should not test it repeatedly. Doing so will slow down your internet speed, which in turn will slow down your miner.

Reboot (new feature added on 8/28/2021)

  1. This feature power cycles the miner without physically having to unplug and plug the miner back to power.
  2. The hotspot LED will turn red once it starts rebooting.
  3. Using this feature will require that you input the username (bobcat) and password (miner).

Resync Miner (new feature added on 8/28/2021)

  1. This feature deletes all blockchain data and lets the hotspot resync to the blockchain from 0.
  2. The hotspot LED will turn yellow once the resync starts.
  3. The blockchain and docker data will be deleted and rebuilt from 0.
  4. It takes 5 minutes for the snapshot to be saved locally. Once completed, a progress page will appear (see below).
  5. Using this feature will require that you input the username (bobcat) and password (miner).

Bobcat OTA Update

1. When will the Diagnoser be launched?

The feature will become available once the upcoming OTA is complete, currently scheduled to push at 7.30 pm PDT 8/3. Please stay tuned for the OTA announcement.

2. How do I access the Diagnoser?

  • Connect the miner to the internet
  • Run Diagnostics using the Helium App or the Helium Utility App to get the miner IP address
  • Enter the IP address in your browser

3. How to get my diagnoser IP from the Helium App?

Follow the screenshots below to access your IP address using the Helium app. If you are the hotspot host and do not have access to the owner’s Helium App, you can also run diagnostics using the Helium Utility App to get the miner IP address.

4. I have located the miner IP from the helium/utility app, but why I can’t access the diagnoser when I enter the IP address on my tablet/PC?

You can only access the diagnoser locally. If your miner is away in a different location (ie. not on the same LAN), you cannot access the diagnoser. Additionally you will not be able to access the diagnoser if you are not using the same internet as your hotspot OR you are on your phone’s data plan while the miner is using wifi/ethernet.

5. I am on the same LAN as the hotspot, but I still can’t access the diagnoser

The miner’s IP address may have changed. Run diagnostics report again to get the latest hotspot IP and use it to access the diagnoser. Any newly added devices into your network may result in a change of device IPs, including that of your hotspot. It is best to fix the hotspot’s IP address first, (especially if you want to remove its relay status, as port forwarding requires your miner to have a static IP address), so the URL for the diagnoser will not change in the future.

6. The diagnoser is showing large fluctuations in my miner’s temperature. Is this normal?

The diagnoser shows the temperture inside CPU. Activities such as the sudden increase of witnesses, beacons or pairing with other hotspots to send blocks out can cause a sudden increase in temperature. There is no reason to be alarmed. This is totally normal.

7. My Bobcat is already installed and it’s hard for me to pair bluetooth to find out the device’s IP address. Is there another way for me to find my miner’s IP address?

Yes. In your router settings, find the device named ‘bobcatminer’. You’ll find it’s IP address listed there.
