The error code you would be looking for is on the miner stats page, in the bottom right corner under the heading PG is where you find the code I think, it will give you a number code. Here is a link to what the codes mean

Just go to the error code heading.
Hope this helps

Edit: fixing up an old post. You find the code under ECHU in the api log

I'm just wondering have you contacted anyone at Canaan? I'm not sure what you mean by asking them 2 times, how was this done? The process for defective units is pretty straightforward and can take a few days to hear back, but you have to at least open a ticket; was this done? Also a while back one of their representatives Steven had been talking with the group and provided us with his email. You probably dealt with him when you bought your 100 unit order, he tends to have something to do with larger orders. His email is Steve@canaan.io .

So far from what I can tell is anyone who has had issues with defective equipment, has had their issues resolved, if they take the proper steps. Good luck.

I have not done this before but your question got me wondering so I did a google search and came up with this setup review which seems to cover it. I would still try and run a dedicated Ethernet if you can. I ran 50 feet just to be able to run these in my garage during the summer. Also as you already have a controller and I didn't look to see when this was written, ignore things about the firmware, just focus on the Wifi stuff. Let me know if it works as that could open up a few opportunities around my house later on during winter. Good luck

If you changed it to DCHP look check your router to see what IP it was assigned, you will need to use the new IP address to access the controller. You can find your routers IP address on the router usually, log into that and it will give you a list of everything on that network, you should be able to find your Rasp PI controller there.

Just realized this is running between 2 threads. try to limit your posting to 1 thread.

So just to be sure you know have the Rasp Pi connected to your home network via an ethernet connection?

You logged into the controller once.
You changed it to DCHP, on the controller.
Now you can't log into the controller. Actually you can't even access the controller IP address.

I'm not great at networking but as long as the controller is set to DCHP, and you have an ethernet connection from the router to the controller; and are using a computer or laptop on the same network. All you should have to do is open the router and find the device with it's new IP address. Is your controller still powered on?

Did you have to change your comoputer/ laptop network settings and change the IP address when you initially logged into the controller? If you did you will need to change those settings back. Have you tried to access the Controller from a different computer/ laptop on the home network?

Other than that I'm out of ideas, sorry

Yeah I could see that, I always try to get a deal anytime I'm buying something, and it does suck when you can't find any wiggle room. I looked at the used units, and didn't like the no warranty, all sales final bit, then I thought about it; and figured that's the same deal I would get on any used equipment. They probably got to the point where they are still making money on them and are looking to unload the equipment; but aren't worried if they do or not.

I only tried to deal with Bitmain a little, and they weren't really helpful, so I opted out of buying through them. For me the reliability was the biggest concern for my equipment so I just gathered the info form the forum and went with Canaan.

I've been pleased other than the inititial F**k around in September where they could have been much more transparent. Since then they've responded well and handled any issues I've had within a respectable amount of time. So I'm glad I went that route.

Once you changed to DCHP, your router will have assigned it a new address, you will need to look into what address it has been assigned and use that to connect from now on.

I would double check that IP address , as it looks like that is the first device to be assigned one from your router.

When you say you reset the controller, did you maybe return everything to default, you might need to go through all the steps again to log in, the same way you did the first time, with the controllers default address.

Unfortunately I'm no expert when it comes to networking; but my fix for getting my Controller changed to DCHP when it first arrived was using a spare dlink router with the address 192.168.0.xxx, so i used that to connect my laptop and controller for my first log in. Once I changed it to DCHP I set the controller up on my home network with no further issues.

Is there a chance that you switched it to DCHP and are still trying to use the old IP address to connect to the controller? Look it up on your router and see what IP address it has been assigned.

If you are connecting to the controller and just cant log in, did you change the password or delete the default password?

I am confused as your name and signature suggest you have a background in cloud mining?

If you want to mine bitcoin then you need an Asic machine.

If you are going to mine with GPU you would be looking into some Alt-coins. They may be able to help you with the profitability in the alt coin forum.

Other than that you would need to compare profitability by using different calculators

You can in a way.

I don't know all the ways to make this work, but you will need a 30 amp breaker on the circuit you plan to use, unless you have 2 controllers 1 for each Avalon and plan to set them up on different circuits.

This 30 amp line can then be run to a single 30 amp receptacle. here's the type of receptacle

https://www.homedepot.com/p/Leviton-30-Amp-125-Volt-3-Wire-Locking-Single-Outlet-Black-R50-02610-0CS/300861633

Then you would get a PDU like this one

http://www.ebay.ca/itm/Compaq-24-Amp-Power-Distribution-Unit-PDU-Low-Voltage-PDUC30a-295364-001/263255393782?hash=item3d4b3e85f6:g:jLMAAOSwFYxZ2~Xp

So it goes 30 amp breaker- I think 12 gauge wire 12/2 should suffice (again not an electrician), 30 amp receptacle, PDU. Then you can plug your Power supply units into the PDU and run them in the same location.

Odds are you do not have a single pole 30 amp breaker in your panel, so you probably need an electrician to wire this in for you.


If you can not make the above happen, then you would need two outlets that are on a different circuit. ( this means a different electrical line coming out of your home panel). If you have the panel space, you can run 2 15 amp circuits out of your panel to your mining location and put 1 receptacle on each circuit, this would allow you to run with what you have on hand.

What are your options where you plan to set up your miners as far as different locations with different electrical circuits??

Hope this helps

Hi there, you are going to want to move this to the altcoins thread. This is for Bitcoin related hardware questions. Someone there should be able to guide you

Yes you can,

But... you most definitely should not, it will not yield anything worthwhile and you will ruin your laptop, so in all honestly if you hate your laptop enough to try this, you might as well throw it off the roof and run it over with a lawnmower. At least you will have fun destroying it.

Or you can use it to host your wallet or something productive like that.

Listen to HaggssFIN in regards to the hardware selections.

This thread is funny to see as my first interaction with bitcoin was to order some pot over the internet and have it delivered to my door. Long story short a service I had been using at the time stopped taking EMT but had this new bitcoin option, not knowing what it was I had bought .34 BTC in about an hour and made my purchase, 2014 or 2015, not sure. Lucky it was a company I had dealt with before as I could have easily lost out because I didn't do the right amount of research that's for sure.

I have made 3 orders through them and there has been no problem. The nice thing is you can use CC for payment as well if you don't currently have any BTC on hand. All my miners have worked fine and were shipped out on time. The only issue I ran into was a supply issue and nothing to do with them, some of the hardware they received was packaged for domestic China sales, so it wasn't sealed, and had small amounts of dirt on the fans. That being said the units ran fine.

There is a thread specifically for them as a distributor here:
https://bitcointalk.org/index.php?topic=2277516.0

I can't speak for the industrial level, although most crown corporations don't care what you are doing with the electricity as long as you pay for it. Larger installs I have seen pay for all their own hardware off the main grid and get a reduced rate.

For home Miners they don't care, you just pay for your usage. If your bill spikes they may come and check your house out for a grow op, but that will probably stop next year.

Hi there not 100% sure of what you need to know. Do you already have the PSU's have you considered buying 1 PSU to power each Avalon, or like i did a large enough PSU on 220v to power 2 Avalon 741's.

If you have and are set on using 2 PSU's per miner, you just have to make sure your circuit is sized appropriately. the Avalons take 1150W so at 110 Volt you need approximately 10.45 amps per miner.

So you would need 2 15 amp 110V circuits to run your 2 Avalons, as you currently have planned.

If you run off a 220V circuit you can run 1 circuit I would say a 30 amp circuit with a 30 amp receptacle; in case you double your miner load in the near future. Pick up a PSU to power both Miners; I use Amitylabs from Ebay, but there are quite a few Miner specific Power Supply providers mentioned in the threads. This way if you upgrade in the future you can buy a PDU and pick up another PSU, without any additional wiring.

For electrical calculations W=V * A, or ask an electrician friend lol, they are good to have.

The specs on their website say yes. Do you already have that PSU in hand? You will need to order a proper cable to run from the PSU to the outlet. Are you planning on taking your dryer out of service for mining lol. If not you can wire up your own circuit and outlet(s) for this project.

I will try and help with the best of my knowledge I'm sure other more experienced miners will show up with their opinions.

1st) I think instead of using the term Node you are referencing Miners. Especially when you get to talking about your Hashrate.  I think the Nodes have more to do with computers running the Bitcoin code (and all the stuff well above my head), or bitcoin core wallets. These make up the network and ensure whatever protocols are supposed to be in place are being followed. The Node stuff I'm not to certain on so I will end that part here and leave it for someone else to explain.

2) I think you have already overshot your budget, The s9's you are talking about I think are currently around 1350 USD or more, not sure I don't run them. So the miners alone for 8 put you over 10K, without factoring shipping, PSU's or taxes and import charges. Maybe scale back to 5 or 6 units. Also make sure you can handle failure rates on equipment, and see how long before you could get units delivered. Have you considered Avalon 741's? They are less efficient and with your higher electrical costs you will want to make sure you can turn a profit.

3) Look into getting Mining specific Power Supply units as these are built for longevity to handle running 24/7

4) Do not solo mine even if you get yourself up to the 8-10 units you will still be a drop of water in an Olympic sized swimming pool, okay maybe 3 or 4 pools. This is especially true if you are trying to show an ROI to attract more investors.

5) I can't help with the remote monitoring of machines as my networking skills are shite, and I haven't needed it yet so I haven't put in the research, but from what I have glanced at it isn't that crazy hard to have set up for you. My pool that I use does actually monitor all connected miners for me which is nice, if 1 goes down it will send me an email alert. Also if you are on the same network as your Miners, which I assume as you said they are in the basement, whe you log into each ones individual IP address you will be able to see how they are performing, I'm sure there is software to monitor all of them at once but I haven't needed it. If you post in the software thread I'm sure someone can help you with that.

6) Where are you located, as you will need to make sure that you are exhausting heat, or using it if it's a cold climate. Not sure that your fan will be able to handle the amounts of heat these miners will be putting out. There are various designs discussed in the threads to help with that.

Good luck

Looks good, I would try and make a separation on the patio between the exhaust and intake fans, maybe even duct the intake fans out and have them make a 90 away from the exhaust fans. Anything to prevent the chance that your exhaust feeds into the intake fan, seeing as they are positioned rather close.

And I'm sure your already planning this but clean up the walls and floor, make sure you have no loose debris or paint that could flake off of the walls, as with those airflows it wouldn't be hard for something to get picked up and run through your nice new miners. Good luck looking forward to the finished product.

EDIT: sorry I just saw the second hand drawing, what is the PTAC room that you are using for intake?
