FutureBit Apollo III - Next Gen Home Mining

[FP91G]

(Edit : added logs)

Hi

New Apollo III owner here from France  
My unit arrived two days ago and node is now fully synced and operationnal.
Unfortunately, the miner part is not working at all    When clicking the start button, it is spinning an spinning until it stops saying the miner is offline (see images below).
Besides, it is showing a "N/A" in the overview panel in hardware errors.

The fan has also a strange behavior as it launches for one second only every minute. Plus, I can regularly hear a "clicking" sound, as if the miner was trying to switch on but couldn't.
I've just flashed the sd card with the firmware and complete the setup process again. Didn't do anything.
Do you have any idea on how to solve that ?

Thank you

(please excuse my poor english)









Here are some logs if it helps :

I’ll quote the images.
There are few logs, and it’s hard to determine from them why the miner is stopping. It might be a software error, but if reflashing didn't help, is there a way to see why critical errors occur when starting the miner?
For this, you need the miner's logs, not the device logs.

Thank you

The miner gives me no logs at all. Here it is
"Unable to retrieve miner screen output: Command failed: sudo screen -ls | grep "miner"
. No miner screen sessions found."

I played a little with ChatGPT exploring the options, and it suspects a problem with the temperature sensor. Seems the miner couldn't reach the sensor, and stops immediately the apollo-miner.service.
So now, I have to understand if it is a firmware or hardware failure.

Without the miner's logs, one can only speculate about the nature of the malfunction. Based on this log, the error could be either software- or hardware-related, it is best to return the unit to the seller unless they can offer a remote solution.
I wouldn't bother testing the hardware of equipment that's under warranty, what does the warranty service say?

Sorry to hear your miner arrived DOA. You may need to send it back if it's faulty. But before you do that, you can try few things yourself, for curiosity:
ssh into it, let chatgpt tell you diagnostic commands to run and paste back. You may get closer to finding reason why its not mining.
Normally you log into it via

Code:

ssh 192.168.1.100 -l futurebit

replace IP with number assigned to the device by your router. Apollo miner is a systemd service there if I remember correctly, run via "screen", you can query it's status, or stop it (so it does not interfere), and run it by hand to obtain full logs, which you can then paste here or to chatgpt.
