Googlefu has failed me. Is there scheduled mining support? When Summer hits I'll have to deal with Smarthours, sometimes the kWh cost will hit 0.44/kWh and I'm often not at home to unplug the systems during these events. And I'm forgetful. I'm looking for some way to tell the S9s to stop mining and use just minimum power for about 5 hours a weekday. I usually have a day's warning on when high cost events will hit.

Good day,
I need my miner to run at 700 MHz during the night and 500 MHz dring the day.
Is it possible to make a time scedule like this?
If not, may be is a good idea to be implemented in the next version.
I have a cheap energy during the night I believe a lo of miners will use it in this way.

As I posted this earlier, crontab is your friend ...
Add 2 cgminer.conf with your desired configs
Example:
Code:
/root/cgminer.conf.500
/root/cgminer.conf.700
/root/cgminer.conf.700
Then edit crontab and set it to copy them before reload cgminer.
Code:
crontab -e
Code:
0 7 * * * cp /root/cgminer.conf.500 /etc/cgminer.conf && /etc/init.d/cgminer reload
0 23 * * * cp /root/cgminer.conf.700 /etc/cgminer.conf && /etc/init.d/cgminer reload
0 23 * * * cp /root/cgminer.conf.700 /etc/cgminer.conf && /etc/init.d/cgminer reload

u can do that with task schedule,
read couple of posts before im sure someone explained how u can do that

This piece of news from the Braiins OS Telegram group is of interest for all the water/liquid coolers out there:
So, no need to pwm emulate or use cheap fans without blades anymore
Quote from: Jan Čapek
- the new update allows running without fans completely
- but it will take us about a week to release

... The latest firmware is supposed to be able to control the fans, did you check they were set correctly? Also see if you have set chip voltage and frequency settings in that particular miner and try if letting it auto adjust works better.
The issue was indeed broken fan. I can confirm, that temperatures in latest BOS are reported correctly and miners are restarting once temp2 hits 95C. Thank you for your help with downgrade command, maybe someone else will find it useful.

Try download this package https://feeds.braiins-os.org/am1-s9/firmware_2018-11-27-0-c34516b0_arm_cortex-a9_neon.ipk and install it from the web ui or via ssh:

How do I downgrade to BOS 2018-11-27 from 2019-01-24 on S9? I found
but 2018-11-27 is no longer available on https://feeds.braiins-os.org/
With latest firmware one of my miners is restarting due to high temperature (was working correctly before update).
Code:
python3 bos2bos.py transitional-firmware-url your-miner-hostname-or-ip
but 2018-11-27 is no longer available on https://feeds.braiins-os.org/

On the other hand...
If you, like me, only have one or a few miners and can afford the electric bill without selling off your mined btc, you will have more btc to sell later when price goes up (if it ever goes up)...

This is a very well written analysis thanks.

Confusing as it may look, this probably just means a unit of measure. As in: number of Giga-hashes per second in 1 minute (the numbers inside the graph, at the left).
The real time measurement is in the small numbers at the table below: Real rate, Chip Rate.
Perhaps this is meant to indicate the refresh rate on the graphic, so it could be perhaps changed to 15m or 24h stats instead? (or planned to).

Awesome job with this release!!
A couple things on S9:
1) Miner Status just states:
"Miner Status: Gh/s 1m"
Is this supposed to have a realtime hashrate number displayed??
2) Will you please consider adding Best Share found? While useless, it's interesting and something I like to check periodically?
Thanks!

Is this a close group?
I cant join,
It says "There is no account with that username?

Does it have the SD slot? If not, you can't use it.
That error simply means 256M of ram is not supported, maybe it needs 512M?

Good news for ollehto, this was just written in the telegram group:
Quote from: Jan Čapek
So, the G29 boards for T1's do have only one DDR module = 256MB of RAM instead of 512MB as in case of G19. We have adjusted the SPL (first stage bootloader before u-boot) to work with G29. It shows a lot of manufacturer competence claiming the boards G29 are the same as G19... Anyways, TLDR -> next update will support G29 based dragon mint miners
So wait for the next version and your board might be supported!

2- AsicBosst column only shows a hyphen "-"
Tested on slushpool, antpool and btc.com, all shows just a hyphen.
Does this work for anyone else?

It's been reported on Telegram

this is only a display bug, AB is enabled. It will be fixed in the next update

I think there may be some improvements can be done in the next release.
1- All miners showing an upgrade icon after a day of running even though they are on latest.
Tried the web-ui upgrade button, it asks to install firmware then prints: "Package firmware (2019-01-24-0-d3cc7c87) installed in root is up to date."
Tried opkg update with same result
The upgrade button is always there.

3- Would be nice to have auto refresh toggle in miner status page too.

I fixed the duplicated MAC address, work great now. But I still wonder why bOS is spoofing the MAC address 
I clocked my S9i to 375Mhz / 8.1volts this give me 8TH at 750w with EVGA G2 1300W / 120Vac.
Best part is fan are running at 10%, quieter than an R4.
Fan control have improve a lot from previous version.
I switched from APW3++ P/S to EVGA because is quieter.
The APW3++ was making more noise than the S9
I didn't try to disable ASIC BOOST to verify from last version, next thing on my list when spare time is available.
Great software !

Updated table
Included HW Error Rates from antminer monitor
When I started testing I set some miners to 775 MHz with 8.7 V and got too many HW errors
So I excluded them from further tests and did not set any over 750 MHz, 8.7 V
But I see each miner shows different behaviors with different freq and volts, so everyone should use their own observations and dont rely on these values

Agree. My ampere meter broke the other day so I will run more tests based on efficiency as soon as I fix it or get a new one. have you checked the HW errors too? February 06, 2019, 04:02:38 AM
If you want to aim for efficiency, you might want to try 500 mhz 8.0~8.1volts. The goal for efficiency is achieving the highest hash rate a single watt can give, even if you end with miners doing 10TH/s but consuming 823watts. Philipma1957 managed to obtain impressive results, you might want to find out which setting is the most efficient, but as you said, each board behaves differently. S9s used to spend 100 watts per TH, but now with Braiins OS they can do 80. Under-clocking should not be underestimated... Agree.
