Re: [PLUG] Does an Open Source Thermostat exist?

I just checked. My zero offset's run from -0.7 to +0.5 °C, based on an hour-long fully-settled ice-bath zero-point calibration, over a sample of about 20 sensors. On Fri, Jul 15, 2022 at 6:07 PM Russell Senior wrote: > > On Fri, Jul 15, 2022 at 5:17 PM Tomas Kuchta > wrote: > > > > On Fri, Jul

Re: [PLUG] Need help backing up my data

Even for a spinning disk that seems really slow, especially if it is rated for USB3.0. I haven’t played with spinning disks in years, but IIRC I was getting 30-40 MB/s writes. This drive sounds similar to yours and is advertised at a max of 220 MB/s. Even half that speed would be quite good.

Re: [PLUG] Does an Open Source Thermostat exist?

The things you listed sound a lot like a full home automation, even if it is just controlling the thermostat. All the sensors needed to detect presence, time, temperature, etc. can be done "simply" using something like Home Assistant (https://www.home-assistant.io/) and no cloud or even internet

Re: [PLUG] Need help backing up my data

I agree, that is VERY slow. Are you sure it is plugged into a USB3 port? Some HDDs are fast at first, but then slow down after their buffers get full (Shingled magnetic recording ), but even then I would expect 20 - 30 MB/s transfer

[PLUG] Need help backing up my data

I have an Ubuntu 18.04 system with two drives in an lvm with one logical root partition. I am trying to back up the contents of the drives (ie /) to an external usb drive using rsync. It is taking a really long time. After 26 hours of continuous operation I have only transferred 138 GB out of 2+

Re: [PLUG] Need help backing up my data

Indeed, that sounds really slow: ( 138GB * 1000MB/GB ) / (26hr * 60min/hr * 60s/min ) = 1.5 MB/s ~ 12 Mbps That's in the USB1.x range. If you use USB3.0 and can get 100MB/s write speed, you'd be done in about 6 hours. Have a look at hdparm to get some info on read/write performance of your
