This is brilliant!

So many posts are about my XYZ is broken, please fix it ASAP (including some/many of mine).

But this one is just a big thank-you.

The combination of Node-Red (to connect Shellys to Alexa), and then the Shelly Indigo Plugin means I can control devices either through Indigo or through Alexa, and status is properly reflected in Indigo. The whole process, including installing Node-Red and learning how to use it, configuring the Shelly Indigo Plugin and joining everything together took 90 minutes all in.

Amazing!
