I know this isn't THE solution but I think moving the donation pool as the second to the last pool could do the trick. So if this really weird behaviour happens it selects a pool of yours instead the donation one.
This can help while I'm finding the real solution.
Moving donation pool to second to the last does not really help here. It still wil uncontrollably miner on that pool if you don't check your miners all the time..
Suggestion: how about adding donation pool in a way that can be removed? This will still leave an option to donate for everyone and to remove it for those with multiple Blades, since all of them most likely removed it manually. Just until you find a better solution..
mmm and what do you think about adding an option to automatically switch to the main pool every X minutes? I mean, Minera could check every X minutes if it's hashing on the main pool and if doesn't it tries to switch to it.
EDIT: BTW I think the problem is related to Nicehash pool only, I'm almost convinced of this. I know it's not a good workaround but if you with this kind of problem could try to remove the Nicehash pool completely (no main no failover) that could be a nice try.
I am afraid that is not such a good idea. For example I have 6 pools listed and when i see a better profitability on pool3 I switch all RPis to it. If those pools will automatically switch back to pool0 that is not ok.
I also think that having Nicehash in pool list is not the reason why these changes happen.
I still think that donaton pool, that can be removed by those, who have problems with it, is the best fast solution.
I Agree Ajeto.
We all know that your Minera software right now, stands above everyone else, but because of this your are forcing a donation pool on a lot of people and if it continues, you will lose the support of those people that ARE donating to you cause they are getting pissed off about this. ( just look at Ginero who is now only known as a scammer and a douchebag ) but LSB and RRTFON are known as gods.
just put a check box of on or off for the donation pool, this way people who want to donate will and those who don't will still praise your Frontend and keep spreading the good word to other miners and i'm shure you will come on top this way, like many others i donated at the beginning to you and sandors and right now i'm not interered in donating more at the moment, but with this donation pool "problem" i'm very close to pluggin that cable to my windows PC.
just my to cents worth but i think a lot of people are thinking the same thing.
Minera Rocks BTW THAT there is no denying it
