Thanks for sharing this flow! In my idea I want to illuminate a living room bulb according to the signal color.
I imported your nodes and stripped away the dashboard nodes. I riddled now for hours but I can't figure out why I'm getting only

"RequestError: connect EHOSTUNREACH 192.107.235.120:443"

errors from the request. I had my network config in mind but is OK, API request via browser works also fine.

My small question torwards you is: do encounter any difficulties acessing the API via node red nowadays?

Thank you!

Sorry I had no errors so far. Maybe you have config a too high request rate? Or do you have a firewall..?
Good luck.

Thank you for the reply - it narrows the possibilities for error.
Also my next guess is network traffic blocking inside my network. I'll check (again).

Hi, I like your input very much. Interesting Information.
I did some exercise with https://energy-chsrts.info.
Now it is up to dashboard specialists to make good looking graphics.

I import your flow and had a complete timeout, if I deploy...!!!

Hi WP-Rue,

load these nodes into a fresh, empty flow. Then check your dashboard. There have to be a chart and a button.
This should look like this.

Hi, I just found that I have a link node (http-request-in 1) in my flow wich you should replace with an http request node in order to get the right data.
