This stuff has matured a lot – and uses technology from the old SUN Solaris days (ZFS) so I built some tests to learn how useful it would be for backup servers and maybe home NAS.

this example uses two pairs of mirrored SSDs – technically two Vdevs – joined in a Pool. Yes too many acronyms! A big file read test uncached is about 1.6 GB/s showing how fast this design is! One thing that’s nice about TrueNAS scale is you get the simple web setup but its just a debian server if you log into it. Whats is less fun is how complex the possible storage setup is. Next test is unplug one of these drives and see what the recovery process is..

After weeks of kitchen work – we needed a better wifi link so I went for a TP-Link RE-450 which is a small plug-in unit which I hooked up to the ethernet point and setup in minutes. Nice design!

I’ve been experimenting with homeassistant – to link up various IoT devices.. ikea, tp-link, philips, sonoff

I finally got around to adding a usb zigbee dongle (CC2531) with mqtt2zigbee and added a temp-hum sensor fairly easily. Next steps: moving hass to an ssd for safety and slowly removing philips and idea hubs!

Well my desktop finally sucumbed to the nvidia driver issue where the driver seems installed but not working. I turned to a couple of blogs people made and followed the driver unininstaller way with DDU, which deleted all traces of nvidia drivers, clicked on the fresh install from the nvidia installer and its back to normal at last!
