Daily power cycle an s9 or l3+ ?

[fyoung55]

Hey,
Would it be an issue if I turned my miners on at midnight and off again at 7am everyday?  I have substantially reduced electricity prices each night and want to take advantage of that, but not at the risk of damaging my miners.  What do you think?

if the room is really cold  the power on cycle would be harder then if the room was a warm room.

I can't say I've heard of any issues in particular with this. More than likely you may wear out your switch before anything else.

I would suggest doing a soft stop. Do this by stopping the mining first and bringing the machine to an idle then shut it down. The power draw wi be reduced which is easier on equipment.

Honestly though if it's still profitable during the day I would run 24/7.

How do I stop mining and bring machine to an idle?  My electric is such so that it is not profitable during the day, but would be at night.  I have a heavy duty timer that I can use. So no worries there.

I'd have to check my antminer gui but I think for those you could go in and delete the pool info then save and apply.

I think you could also kill the network connection, if you had to. I have really only done it with my avalons a handful of times when moving them

I don’t think removing pool info will do it for antminers but you could try. Mine will seem to continue to hash even if the pools are down or my internet connection is disconnected (but with pool info intact). However, one way to ‘soft stop’ that I can think of is to restart the miner. During the start up process, it will not hash right away so you could use that window to turn off the machine. However does doing a soft stop actually help with the electronics, I don’t think so.

deleting the pool information does not help, the miner then runs for bitmain.
Antminer have no idle mode. I start a miner every day 3 to 4 times with cable plug in and unplug.

so we think it's probably ok to power cycle?

Soft stop would be much more preferred and this is my first time on hearing out different electricity rate in the morning and evening?

the only soft way to power off is 2 separate psu's

one does the hashboards the other does the controller.

it is a bad method since the psu running the controller can fail the board will stay hot and the fans would be turned off.

some areas have cheaper night power.

at op just do it. hit a switch at 7am shut them off.  hit a switch at 12midnight turn them on.

I gather you will be 7 hours on 17 off.

so how cheap is that 7 hour on rate vs the 17 hour off rate.?

I've been doing this for the past 4 months with mine. No issues so far.

I have solar, so I start them before I go to work at 6am and turn them off once they are using more power than I'm producing at about 6pm.

I have other miners running in that room, so the room is never really cold.

A lot of Solar power guys do this. I find if you unplug the power cord from your internet router/modem first, the miners lose their internet connection and are disconnected from the pool. Wait a few minutes for the miner fans to cool them off, then switch off the miners and reconnect the modem/router power.

It's a bad idea to just switch them off while they have been mining and are heated up. Heat will kill your chips so let them disconnect from the router/modem and cool with the fans for a few minutes beforehand.

Id be interested to see how the miners go back to mining for bitmain if you delete all pool info All 3 and then save & apply. I agree it does mine to those addresses when you first turn them on until you update it with your information.

What, have I been lying to myself. When I've removed all pool information and save it I was certain I was killing the majority of the power by stopping hashing. (shows at poolside, and GUI is empty on miner status page but still accessible)

I know there is still controller power and there will be power at the boards but with minimal draw, my suggestions where just to reduce the load on the hashboards to a minimum and allow them to cool by the fan. I've also unplugged the network cable in the past if I was by the miner while setting up.

If I'm wrong I know have another issue with Bitmain gear lol. Just part of my other life seeping in, I like to unload before stopping equipment.
