I know Phill loves mining, so why not do the opposite of that? bring in more gear, and make it worth it to hire someone to do the periodical check-ups, it doesn't have to be a salary, it could be paid per visit, or a percentage of income, I don't think it's impossible to find someone who is young, willing to learn a thing or two about maintaining a mining farm, lives nearby, and can be trusted.

It takes on average no more than half an hour a day, I'd say 3 hours a week is the average, a farm with 5ph makes roughly $350 a day, so even if that person asked for 100$/hr, it's just a matter of 3 something days worth of mining, I don't know about wages in the state where Phil's farm is located, but I highly doubt 100$, it will be on average 1 drive per week, any time of the day, 3 hours, reboot a device or two, change 2 fans, dust off a PSU and go home.

Ya, the same guy needs to ship a miner to another state for warranty repair and call the electric guy to come to fix something. Still, the work they will do doesn't require any special skills, so if I had to look for a guy like that,  trust and desire for work would be the only things I would look for.

It's hard to tell how someone got confused, but sure that mindrust isn't the average "post anything" kind of member, so I am sure something confused him along the way, I believe it's the fact that miners do indeed need DC, so to someone who doesn't understand much about the subject, they would not think that DC devices need AC power input, the logic behind it is not easy to understad.


Hard to tell how does he operates, his battery has the capctity of 28,800Kwh, so nearly 3 hours for the set up assuming 100% DoD, but if I had to guess, he is probably not running them at stock settings, S9s can run on Low-Power-Mode doing 750w range, L3s 600w range, and S19 1800w range. so we are talking 30-40% less power consumption for the whole set up, but let's hear from him.

You have got them mixed up, solar panels generate low voltage DC, asicminers just like most other electronics require AC at the PSU input, the PSU of course will have to convert that AC to DC to run the miner's chips, but you can't just feed the miner with DC and expect it to work, it won't for so many reasons that are not best fit in this topic.

Another pro tip, just mouse hover on the error when viewing the Whatsminer tools and it will tell you what the error means without having to fo to the miner webpage, also, double click on the miner's row takes you to the webpage of the miner.

I would like to thank you for both using my services as well as making the review, I would have loved to see you run both gears at the same place so we can compare temps, fans and power, doing so when each model runs in a different place with different voltage and cooling will not be fair.

230v is great, those m50 gears must be running without much effort, anything between 220v and 240v is good, higher is better for PSU, cables and everything else that carries power to the miner, slightly below 220v i would not bother, temprary below 210v is ok, but running steady for long period of time at 203v is something i won't reccomend, so ya sure thing call the electric guy, it is thier JOB to give you proper voltage input since you are paying for it.

@Sledge0001, I have bought and sold hunderds of the m30s, +, ++, various m50 models were sold to my clients, none of them hashed at specs, all run higher which is great and people loved it except for one client who was mad at me because i sold him some 100th m30++ which did 106th and he said his pdu was near full and could not handle the extra 200w per miner lol, luckly he was able to use powerlimit and did not insist on returning , I now have to make everyone aware that I won't be responsible for gears that do slightly higher hashrate than what is on the label.

Those can be somehow inaccurate since temps inside the farm will differ by a considerable margin depending on the airflow, turbulence, not enough exhaust causing heat to re-enter the miner, not enough intake space and etc.

As you can see the miners are reporting 25-26c while your sensor is reporting 18.4, that's off by nearly 7 degrees, it's always best to check the miner's temp sensor rather than external sensors.

But anyway, temps are still good, and don't worry much about them even if the room heats up, the miner will tune lower and will go into protection mode both on PSU and hashboard levels if temps can't be kept low enough.


That is pretty low, in my previous post I meant to say below 220v, which is the minimum stated by the manufacturer, but I have tested some M30s all the way down to 205v and they ran just fine, even those that threw a voltage error did not seem to bother and just kept going.

I am pretty interested in hearing the compassion part between the M30 and the M50 especially that now the price difference between the two is just about 2$ per th.

A pro tip, going to the Whatsminer Tool and going to display settings, you will find a lot of fun stuff to show like the daily power consumption, also you could exclude a lot of the not-so-important info like the power supply version and all that things that you won't need for daily monitoring, just to keep 4-6 columns that you actually use.

Let us check your voltage at the PSU meter, go to whatsminer tool and follow this.

 Settings > display mode > custom > add PowervIn

This will display the voltage at the PSU, yours seems to be below 200v which is why you get that error.

Also, you can add EnvTemp which is vrery useful too.

I still doubt it's something easy to do, given that some multi-billion dollar companies like Hikvision with 12B in revenue last year alone still don't use their own mail server for all types of alerts coming from all the different DVRs, NVRs, and Cameras they sell, you still need to set up your own mail server to get notifications.


Lol, that's what my wife calls them whenever I check and she sees me busy looking at my phone/laptop.

You can let them use their own mail servers, anyone with a Gmail account can get mail server info, this is how some software work.

However, almost all pools i used still send out notfications via emai from their own mail server, not sure how they avoid getting flagged, I assume they use a dozen different mail servers.

I sure bet Kano isn't the nicest guy you would meet on the internet, and I disagree with him on a lot of subjects, but in this case, I think you are overreacting and you are in the wrong -- not him, maybe he could have replied you in a nicer way, but ya, this is the internet and you are going to need to grow a thick skin to survive.

The instructions are clear, just because you use some weird OS, it doesn't mean anyone related to the software/hardware you use needs to give you any kind of support, especially not when it's free, I was trying some mining proxy the other day, and I had only a Windows machine nearby, that proxy runs on Linux ONLY, imagine me going to the thread and asking (my windows cmd isn't responding to the apt commands, what should I do?).

I had to figure out my own shit, and when I did, it became just a matter of following the simple steps, mind you, I don't have half the experience you claim to have with computers.

Anyway, if you still need help, start your own thread in the software section, explain in detail the errors you are getting, the exact distribution you use, and I will be more than willing to help, and I am some others would as well.

I learned it the hard way to be honest, sometimes regardless of how you oversize your cables and tighten them, one or some of them might start to become a bit loose and leads to overheating and eventually even fire, so checking that nothing is warmer than usual gives me a truckload of piece of mind.



Ya, I would imagine something like that should cost a lot regardless of which country that setup might be.



I use AwesomeMiner, it's owned by a fellow bitcointalk member.

Ya having access to a PC that runs on the same LAN where miners are located is a must (unless you have your gears at a hosting company where they don't give you that access).


Pretty much depends on what type of miner you use, with Whatsminer it's pretty rare to have permanent hashboard damage for new gears, the software isn't perfect in the tuning aspect tho, so it could tune with low hashrate and thus needs a reboot to fix it, so using a local-management software, in that case, is usually a must, with Antminer it's a bit different, it's common for a hashboard to lose hashrate and requires reboots, but it tunes a lot faster and gets to full speed in no time compared to Whatsminers.

By the way, since you already have a script in place, is it also available for your pool users or just a personal thing? I think getting email notifications for lower than average hashrate for all pool users (if they want to set up) would be a good addition to any mining pool.

Most do, but I don't think it's a great idea to count on them 100%, better have other measures that go along side the pool notification.


Indeed, in fact, most pools only have 10 mins hashrate report and above, the ones that report "current" hashrate are just way in accurate and will give you many false positives.


Seems we are talking about two different things here, you are talking about home mining where you have a few rigs in the garage vs a mining farm which in 99.9% of the cases won't be anywhere near your garage, I have yet to see any mining farm or a datacenter /host that are not equipped with CCTVs, even the cheapest mining contains that ship from China come with CCTVs by default, it's not even an adds-on or anything like that, it comes with the walls, I am willing to as far as betting that at least 95% of mining farms have CCTVs because 95% of the mining farms are located in places where the people who own them don't sleep next door to them.


Again confirms why we aren't talking about the same thing, but I agree if the setup is in your home and you are not following the code, it is probably very risky to leave your gears unwatched, in fact, it's risky to run them in the first place, but still, there is a huge difference between running a few gears at home vs a large farm in another city/country.

Sometimes I think I check my gears and hashrate way too often, I think I log in to the farm PC at least once or twice a day, but I look at the pool status no less than 10 times a day to make sure everything is working fine despite having notifications all over the place, I can't help but look to make sure everything is working fine.

How often do you check on those boys? what do you think is normal and at what stage would you recommend someone to go see a therapist?

Also what measures do you take to reduce the need for you to visit your pool app or webpage?

Things that I do (which obviously aren't helping pretty much with the constant paranoia)

1- a local monitoring software that monitors hashrate and temp with Email notification to an email that's open on my mobile phone, I get emails for over-temp, gear off-line, and lower-than-expected hashrate.

2- a temperature and humidity sensor with an app notification for temp/humidity.

3- phase monitoring relay which shuts down the whole farm when there is under/over voltage or phase failure.

4- Motion detection on the CCTVs to spot any intrusion.

5- Some Fireball fire extinguishers placed at the farm (want to get more of them soon since summer is approaching).

6- Oversized all the wirings and electricity infrastructure and not going above 80% of anything.

7- A heat gun to monitor all wires, sockets, MCBs, Busbars, etc when I go to the farm, just to make sure nothing is getting hot.

8- weekly check-ups on the transformer gauges to make sure the oil level is in place.

9-I shut down everything during rainy storms and abnormal heat waves.

10- periodical dusting and cleaning (depends on the weather).

These are pretty much all the things I do to have some peace of mind and to ensure that everything runs smoothly for as good as possible, looking forward to hearing yours.

While mining with any kind of hashrate gives you a chance to solve a block, doing so with anything but ASIC (USB sticks and higher) is just a terrible way of doing thins, for one, the power consumption on something like a GPU is going to be higher by a few orders of magnitudes when comparing wat per hash, the second reason would be not knowing if your miner is actually working.

When solo mining to a pool there will be a minimum difficulty target at which you need to submit shares at to get pool status so you know your miner is up and running without any issues (viewing that locally alone could be misleading), mining with something like 11kH/s means you won't even know if your gear is online, it will take you a while just to get a share above pool difficulty so let alone network difficulty.

I am not against doing that for the sole purpose of learning, but treating it as a lottery ticket will require an ASIC of some kind, and to those who think well, mining with a 1TB USB stick still has almost no chance, ya that's true, but mining with a CPU or a GPU is worse by A LOT, with the 1TB it's like hunting a rabbit at 12AM in the middle of the woods, with a GPU/CPU it becomes like trying to get a headshot on a mosquito that lives in the next country.

Merit earning is like Bitcoin mining, it's a combination of randomness and hard work, you could be trying to solve a block for a year, and then on the first day of the next year, you solve 2 blocks in a row.

I don't follow my earned merit closely but I am sure even after gaining my first 1000 merit, in some weeks/months I had little to no merit, in some other weeks I could have gotten 300 merit, then 40, then maybe nothing for a while, it's pretty normal, you will need to measure the number of merit against the number of posts on a very large timeframe, perfectly would be against infinity, a few months is the minimum IMO.

I still get merited for posts I forgot I ever wrote, had I waited for merit to come to those posts when I posted them I would have been very disappointed, and I am sure this applies to everyone else, you need to stay patient and consistent, eventually on some period of times you will get more merit than you ever thought possible, the pace at which you earn your merit is usually going to be like a staircase, flat for a while followed by a steep slope, so just hang in there and stay consistent with the quality of your posts, merit will come your way.

It won't, it will only give you more acceptable shares, a bit less hashrate report fluctuation on the small time scales, it will also result in more pool traffic, but will not change your chances of hitting blocks,  500k diff shares won't solve a block, the share that solves a block will be by default way above 1m anyway.

It's easy to blame Bitcoin price for such failure but that's far from the truth, TSMC and Samsung still make a dozen chips for their mining gears manufacturers, and Bitmain and Whatsminer made trucks full of money in recent years despite the drop in BTC price, they both still sell their ASIC miners at prices way above cost price.

Intel walked into the room with their big boy pants showing off some crazy efficient numbers, they made everyone thinks that they will dominate the field, but they failed massively to their rivals who have a lot more experience in designing ASIC chips which so happen to be very different from the GPU chips.

I am not happy to read the news tho, I want nothing but more competition in the mining sector, but things happen.
