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;


Before downloading the flow, if you find this interesting or useful, please do consider buying me a coffee. Every little helps feed my often insatiable tech. appetite!
