Same here...

I don't have any error message.
Evrything started when the Fan Out showed 0 RPM.

I even tried to trick the software...
I activated again the "Auto Stop Miner" and set the out speed to 0
Then i exported the Miner. json file and set there the value from 0 to -1
Did not help...

I also opend the miner and checked the boards and they are all fine.

One thing is strange.
Normally when you look from above on the boards you can see some leds blinking.
But now i only get 2 boards blinking, one board does not blink but the led is on and 1 board does not blink at all...so maybe dead?

Hello

I have the same problem now.
Fan out shows "0" and the miner does not mine.
But the fan is turning...

I have deactivated the "Auto Stop Miner" -> Still not mining
Made new firmware stick - > Still not mining

Someone has an idea?

Hey

I've tried different firmwares and the best i've found is version 20180930
Stable hashrate, no need to reset the miner and overclockings works also good.

Hey Daniel

I'm sorry to tell you that the advertised profit you saw is long gone...
If you wanna know why, you should start read from page 21.

The profit for this miner is gone and won't come back.

Maybe it's because we mine on diff. servers?
I live in europe so i mine on the EU server.

Strange...i'm on NiceHash and i only get 1-3% rejected shares.

Please check the "ASIC Status"

If you have to many chips on yellow or red, then you get a lot of rejectet shares.
If this is the case, go to the settings page and click on "Save and restart miner".
Wait 5 mins, then check again the "ASIC Status". Normally it gets better after a restart.

If not, "Save and restart miner" again or choose the "Save and restart machine".


And yes, profit is very low right now.

Hey

Go to page 21 and start reading from there...
Page 21: https://bitcointalk.org/index.php?topic=5038441.400

I use 20180930
I't's good for overclocking and it's also stable.

Access over ssh

user: root
pw: envision

You (your home network) are probably not in the same ip range as the miner.
The miner has by default a 192.168.1.xxx ip address.

If your home network is in the 10.x.x.x , 192.168.0.x or any other range, you won't be able to find the miner.

Version 20180930

Hey metnet

Look, i've never tried to access the file the way you do it. So i can't tell you why you don't see the "auto_frequent" option.
What i can tell you is, that "auto_frequent" is the first option you see when you open the miner.json file.

This is how the file looks like when you export it from the miner setting page (miner.json):

{"auto_frequent":"0","frequency":"900","check_nonce_submit":"1","auto_restart_miner":"1","restart_lower_limit_hashrate_5m":"4","restart_hw_count_30s":"74","auto_stop_miner":"1",
"stop_lower_fanspeed_in":"2000","stop_lower_fanspeed_out":"2000","stop_high_temperature":"70","temperature_unit":"c","refresh_time":"60","system_timezone":"Europe\/Zurich",
"system_hostname":"dayun","system_protocol":"static","system_ip":"192.168.1.222","system_netmask":"255.255.255.0","system_gateway":"192.168.1.1","system_dns_server":"192.168.1.1",
"pools":[{"id":130,"url":"stratum+tcp:\/\/lyra2rev2.eu.nicehash.com:3347","username":"xxxxxxxxxx","password":"x"},{"id":131,"url":"stratum+tcp:\/\/lyra2rev2.usa.nicehash.com:3347","username":"xxxxxxxxxx","password":"x"},
{"id":132,"url":"stratum+tcp:\/\/lyra2rev2.jp.nicehash.com:3347","username":"xxxxxxxxxx","password":"x"}],"user":{"id":15,"username":"xxxxx","password":"xxxxxxxxxx"}

Not much...it just dosen't work.
The miner accepts the new settings, like a higher frequency, it shows the higher frequency on the main page of the miner, but it still mines with the default frequency of 900 MHz.

You can export the config file (miner.json) from the settings page of your miner. In that file you can change the value of the frequency (MHz).
To edit the file, i use a tool called "Visual Studio Code" You don't need this tool cuz you can edit the file with the Windows Editor.
After you edited the file, you can upload it back to the miner over the Settings page -> miner reboots.

Change the value of auto_frequent from 0 to 1: "auto_frequent":"1"
Change the value of frequency from 900 to 950 or 1000: "frequency":"900" or "frequency":"1000"

Only do this changes after you upgraded your firmware to version 20180930 or higher.

About HDAC you guys are talking about...

They did a algo-swap from Lyra2Rev2 to Skunk
Source: https://hdactech.com/en/News/news.do?mode=view&articleNo=6951

Quote: The change will be applied from block number 151,880, and it will be applied on (GMT + 9) October 22, 2018.

All the guys mining there did just come "here" to us.
That's why the hashrate went up...

Just asking myself how this coin had this hashpower...anyway.
It is what it is....

I only know a device that cools the miner with oil...

You know what's funny about this?
The hashrate of Lyra2Rev2 went actually down on Nicehash.
Not by much but it did.

Theory 1:
Big order went out (Z1/Z1+) and the miners got online this night.

Theory 2:
Another manufacturer is testing a new miner.
