Updates to announcing Reolink doorbells on Alexa

A while back, I wrote a post on how I build a Node-Red flow to allow me ask specific echo devices to announce visitors pressing my ReoLink doorbell. This worked great, but there were a couple of shortcomings; 

 

• The list of registered devices would last only as long as Node-Red was active. If I needed to restart the Node-Red docker for any reason, I would also need to re-register announcement devices. 
  
  
• The ONVIF node the flow relies on is a little flaky, and will occasionally just disappear from Node Red. 

I've added functionality to store the list of devices in a text file, so it persists between Node-Red restarts. I also added some notes on how to recover from the self-destructing ONVIF nodes, bring this all up to v1.1.1.

The device list saving is managed automatically as part of the voice registration process, but there's also a manual trigger that can be used in testing. If you use this, you might need to adjust the save and read file locations, particularly if you're not running Node-Red in a docker, like me.

The full flow is pasted below;

Migrating Deprecated Unifi Docker on unRaid

I've been using LinuxServer's Unifi-Controller docker for a long time to manage my unifi devices. However, this has been deprecated and to keep up with new releases, there is a requirement to install a Mongo database docker and a newer Unifi docker. This sounded like a bit of a faff but I thought I'd give it a try before succumbing to a physical controller device. The process did not go well, and I couldn't seem to get the systems to work together.

However, in searching around for solutions, I saw there was a new 'all in one' option, the Unifi-Controller-Reborn docker from PeteAsking. (find it in the Apps tab). I gave it a whirl and was able to get my old setup running in a shiny new Docker. Along the way were a few learnings that I thought I'd log here for posterity.

Announce ReoLink Doorbell on Echo Devices

I recently installed a Reolink POE Video Doorbell, and like it a lot. Its got great picture, doesn't require web connectivity, and integrates really well with my Unraid.html">Blue Iris set up

. The only issue I have is that notifications on my mobile are poor and often missed. The bundled chime works OK inside the house, but when I'm in my detached office, I can often miss visitors.

I thought it would be nice to have the doorbell ping my office Alexa when pressed. Of course, there's a skill for that, but as someone with a penchant for Node-Red automations and too much time on my hands, a project was born....

Alexa Music Playback through Marantz / Denon Heos

Arising from a query on reddit, I revisited something I'd set up quite some time ago and forgotten all about: using Alexa to play music on my HT system. It works;

As can be seen, the processor is on CD input to start. When I ask it to play music, it switches to the HEOS input and plays. If the processor had been in standby, it would have been woken and switched to the correct input.

Also, only the music content plays through the speakers,, the Alexa responses come from the echo device itself.

Set up Reolink Doorbell video with BlueIris

I recently purchased a Reolink Video Doorbell PoE on Amazon prime day to replace the Comfort intercom thats going on 20 years old. I selected this item over others as it supposedly integrates with BlueIris which I use for all my other surveillance cameras.

There's no distinct guide for setting this up that I could find, so here's what I did, for posterity.

Building an UnRaid Home Server for Media Storage and Automation

Are you looking to create a versatile and efficient home server that can handle your media storage needs while seamlessly integrating with your home automation system? If so, building an unRaid home server might be the solution you've been searching for. In this post, we'll explore the benefits of unRaid and provide practical advice on building your own home server for media storage and automation.

I've been using unRaid for home storage and automation for about 10 years now, and have been blogging about it here for almost as long. A lot of my posts are quite specific, so I thought I'd try a high level guide for those starting out. Let me know what you think, or if there are other specific topics you'd like to see covered.
