Splashtop Latency Demo

A user over at unRaid Forums asked me about latency when using SpalshTop Personal to access an OSX VM running on unRaid. I promised a quick video to show it in action. Sorry about the delay!

Enabling HEVC on Rx570 in MacOS VM

In following the MacOS Bare Metal thread on unRaid forums, it was bugging me that I wasn't getting full performance from my VM GPU. I have a Sapphire RX570 4GB passed through to a Mojave VM, and while it was showing Metal and H.264 encoding support, HVEC remained resolutely elusive.

It should be simple, enable Lilu and WhateverGreen kexts and go. It turned out to be anything but.

Solved - Av Access USB prevents system boot

In a previous post, I'd detailed my setup of using a  4KEX100-KVM  to extend an unRaid VM to a very remote screen over ethernet.

This has worked out great, with one exception. With the Av Access transmitter USB plugged in to my server, the system would not post. It was necessary for me to unplug the USB, wait for post and unRaid to start booting, then plug the USB back in.

This was a chore, especially as my server sits in my attic and can be a pain to access.

I was living with the issue as thankfully I don't need to reboot too often, but in researching something else recently, I came across a known issue with some older USB devices. It turns out that some USB devices feed +5V back to the host adapter. This can result in some motherboards failing to post - my symptoms exactly.

The extreme solution is to sever the +5V wire in the USB cable (!) but before going that far, I decided to try placing a USB hub inline between the USB host adapter and the transmitter unit. Hey Presto! I can now boot and reboot without issue.

All hail the interweb.

Video Surveillance on unRaid

Inspired by everyones favourite unRaid you tuber SpaceInvaderOne's then partially completed series on setting up CCTV in unRaid, I figured it was time to get started on a little bit of home security.

I'd previously worked on building an interface to my legacy Comfort alarm / home control system, and that's fine for basic alarm, but video was always the next step.

SpeaceInvaderOne conducted a basic analysis of cameras and software available, before publishing a walkthrough of how to set up his chosen Shinobi docker. This, along with some other research, started me on my journey. I went ahead and purchased two of the SV3C 1080p PoE cameras he mentioned. These would connected to the spare PoE ports on my Unifi Switch 8 (see my Unify blog post for more details).

I tried installing Shinobi, (before the walkthrough dropped), and failed miserably. In any case, I'd previously researched the area and at the time decided that Blue Iris looked like the best option for scalability and integration.

UNIFI: The start of something big....


'Dad, the internet's slow!'
'Dad, can you restart the Wifi?'
'Dad, will we ever have WiFi in the kitchen?'

It was getting tiresome. A few years ago, I'd augmented the ISP all-in-one modem/router/WiFi with an Archer wireless router and a couple of Huawei extenders. This was an improvement, but never a satisfactory, long-term solution.

I'd been reading a lot about the Unifi range from Ubiquity and this week bit the bullet and purchased;


The idea was to provide decent wifi throughout the house, with 2x access points connected to the Switch from which they would receive both data and power. As an added bonus, the fully managed switch also supports link aggregation, so I could leverage both ethernet ports on my recently reconstructed MediaServer8.

Despite copious amounts of reading & research, and pre-installing the Unifi Controller Docker on unRaid, setup was not as smooth as it might have been.

Total Harmony


It was getting quite ridiculous. This is the set of remotes I had built up to control my HT. From right to left; Receiver, NowTV box, PVR, FireTV, BluRay, Projector, Squeezebox, DAC.

It's little wonder no-one else in the family used the system!

In the past, I'd used various Logitech Harmony remotes but all had outlived their usefulness and have been retired. A few months ago, I'd picked up a Harmony Companion set on Amazon warehouse for a steal, but hadn't got around to configuring it all until now.
