Concerning, very. Would this allow them control of device as well? 10min "downtime" to mine for themselves?

Until someone has one of these miners and goes through the code, unknown. That possible re-direction is what folks were worried about with the s7's.

Does no one have a problem with the miners phoning home?

GMO's btc miners are disappointing. The 1950w box barely has +20% efficiency to the S9, and this has even worse efficiency than the S9.
The fans must eat 200w, trying to cool 3400w in that box.

Overclocked b2 with higher CFM fans?

Quote from: GMO

Surveillance API
Operation Detection (Anti-theft Measures)

As was the case with Bitmain's s7 remote shutdown (Antbleed?) had it ever been activated it sounds like the miners report home either at boot or periodically when running. The anti-theft measures means GMO can brick the miners at will. Thing is, I'd assume the miners need to phone home and get a permission key before they will run.

I for one will never allow a miner or any other device to do that. Even Bitmain's s7 allowed phone-home (had it ever been activated) to be disabled.

Agreed, the efficiency is terrible. Also this would practically take up all of my 240/30A line with one miner. If arrived today is just $24 in profits at my power rate and 3k days to ROI at the price mfb would set. Not sure if this worth listing. If I was able to run this and one s9 I'd still be short at least $10/mo in profits compared to whats running.

I suppose the only silver lining is if this arrived just in time for a large bull swing Q4, where efficiencies are still a factor but less of an issue. Not sure if we'll list this one or not, we've been hoping for new tech to be more efficient than this.

PS. I really would be scared this would flame in my garage.
