The wifi dongle ability has been in a few releases now... unless theyve broadened compatibility or something that is...

2.6.12 doesnt add anything to the scheduler, it seems to add only the ability to use a wifi dongle

my above posts about custom crontab are not part of the newest FW, and should work just fine in 2.6.1 and possibly much earlier firmwares

   he sold me one for 409 usd shipped it out to me fast  it was  the older sp20 not the sp20e.  works fine.  684 watts at the wall 1215 gh

 0.563 watts per gh.  he also sold me at least 2 maybe 3  s-3+'s    last year all good gear.

with only a single row of racks/shelfs it would make no sense to change the layout...

a bit confusing...
is that custom day/night your mod or did it come with V2.6.12?

thanks for the spec PDF. I was misleaded by the safety current which is 2.12A+/-10% and printed on the label of the fan.

damn who is this guy lol

looks like 60 or so units of SP20 and they look well used.  I assume he bough them at the much higier $600- $800 rate.

His layout is terrible as well I don't understand why he did not go with a hot/cold aisle layout  :  the Sp20 is well suited to that type of layout

due to the vented front and enclosed case. 

 I would hate to see his power bill

i also think than one of sidechains creators is Satoshi

finally i think i understood something in sidechains

not sure you need to back anything up. my process:
1) ssh in with root/root
2) "vi /etc/mg_custom_mode_day"
3) copy the above settings, then in the ssh vi editer press "i" (enters the insert mode) then right click (this is how to paste in ssh), then adjust as required.
4) press 'esc' (leave edit mode), type ":wq" (saves and quits)
5) repeat steps 2-4 but with "vi /etc/mg_custom_mode_night" and your nighttime settings
6) "crontab -e" (enters cron file)
7) below the pre-configured jobs, and above the "## voltage start" line (thats where the webUI scheduler puts its jobs), press enter to create a new line
copy the cron lines above, press "i" for insert mode, and paste with right-click. adjust as required (remember its UTC, and look up how to set cron times if you need help)
9) press esc to stop the insert mode, then type ":wq" to save and exit. the cronjobs will now be set, close the SSH

note: if you mess up inserting text, use ":q!" to quit without saving. re-open the file and try again.

what i need now is an easy way to copy these settings to multiple machines on the same network, and I am not 100% sure if the cronjobs will persist after a firmware update

this is neat , I need to modify my sp20s to use these settings , I dont have anything backed up though

my new suggestion for crontab control that implements a daytime mode from 7am-6pm on workdays to coincide with the local electricity rates:

00 07 * * 1-5 cp -rf /etc/mg_custom_mode_day /etc/mg_custom_mode && logger "daymode" && /usr/local/bin/spond-manager restart
00 18 * * 1-5 cp -rf /etc/mg_custom_mode_night /etc/mg_custom_mode && logger "nightmode" && /usr/local/bin/spond-manager restart

mg_custom_mode_day:    FAN:4 VS0:630 VS1:630 VS2:630 VS3:630 VMAX:660 AC0:165 AC1:165 AC2:165 AC3:160 DC_AMP:170
mg_custom_mode_night:  FAN:50 VS0:680 VS1:680 VS2:680 VS3:670 VMAX:710 AC0:230 AC1:230 AC2:230 AC3:220 DC_AMP:170


EDIT: tried it out, and realised that even though the miner is in EST, the crontab is based on UTC. I had to bump both times forward 5hrs (ie 12 and 23) to trigger at the correct times. System spun up the fans for a few seconds to implement the changes, then continued to mine with the new fan/voltage/wattage settings in place (no reboot required)

IMO this might be more useful for anyone who wants more complex scheduling.

update: changed 'echo' to 'logger' presumably this will properly write "daymode"/"nightmode" to the log files when the change occurs. SP-T support clarified a reboot isnt required, so the above commands should work fine. (it was suggested that changing ACx isnt necessary though, i guess because ideally it will be set to whatever the PSU limitations are, rather than desired power draw at each mode)

i changed the system time to local time though. I set another adjustment to occur during the night and it seems like that one happened correctly as expected, but unfortunately i wasnt awake to hear if the system changed its fan speeds drastically in the adjustment.

I see 2.6.12 is now available so am downloading it to see whats new. hopefully some further abilities are added to scheduling
EDIT: 2.6.12 is crap - voltage settings are all lost and cant be configured, so all loops are Off/null/disabled. I cant seem to input any settings to make it start mining. The fan keeps revving from 0-20 every 3-4 seconds.
EDIT 2: went to change back firmware, clicked manula selection, my only options are 1.5.8 and 1.5.10. The Sp20 now seems to think its an SP10 - what do i do?
EDIT 3: used SSH, typed "echo SP2x > /model_id; echo SP20 > /model_name;"  and was able to get the device to download the 2.6.12 again, this time operational

2.6.12: seems like theres a wifi function (requires dongle, presumably in the system's USB port). no visible changes or improvements to scheduling though. For that reason im curious to know how changes to the /etc/mg_custom/mode are implemented. Is a reboot required, or just restarting the minergate process?

seems like it could be easy to create a cron task that simply copies different mg_custom_mode(day) and mg_custom_mode(night) files to the actual mg_custom_mode and then re-initiates the miner. It would allow better fan control and precision tuning the voltages and wattage limits for each schedule, rather than just the max voltages

If it's working OK - I'd leave it 

seems to be missing.  so should I roll my 2.6.9 back to 2.6.7

Just thought I'd drop by to congratulate Spondoolies-Tech on their superb customer support & efficient RMA process - truly excellent!

I lost a loop on one of my SP20E's, & after SPTech logged in remotely they quickly decided to RMA it after confirming the fault. I was sent details & info for shipping the unit back & as soon as I had sent them the tracking number they dispatched a replacement which I received yesterday (after a long & still ongoing argument with DHL - see below). Customer service like this is hard to find in the Bitcoin world & is the reason I will be using SPTech for my future mining hardware needs. Again, a big thank you to all SPTech staff - massive kudos  

DHL - different story  

They're still trying to charge me tax & import duty on the replacement unit, despite me sending them all the required documentation to prove that this was a replacement unit, the entire email conversation with SPTech & after SPTech kindly wrote to them to confirm what I had already explained to them on multiple occasions via email & phone conversations. Good luck with that DHL  

Peace  

Edit: I don't see the 2.6.9 or 2.6.10 firmware mentioned above on the manual upgrade button - has it been removed?

Yeah im holding out for a drop before I buy anything

If you buy the nano farm (http://www.spondoolies-tech.com/products/sp20-nano-farm-batch-1), the shipping is free.
For one SP20 shipping to Slovakia, do a dummy purchase to let the shipping calculator give you the total.

how much cost shipping one SP20 Jackson  to Slovakia ?

My recollection is that with the setting of timed "actions", the time specified must be in UTC. Of course if you live in Greenwich England, this won't matter. This is kinda a surprise, but not so much when consider that Linux is inside there.
