as I can understand you HC2 and node-red not in the local network.... ohhh

I have a separate VLAN for IoT devices. As you probably know these are the most vulnerable devices, even in a LAN network.

 

Because the communications you are using are unencrypted, password are easy to intercept. That's why I made a comment about the Global Variable writing, using a administrator account.

 

The only way to use encrypted communications available by the Fibaro HC2, is to use scenes. They have the capability to set up encrypted  communications.

 

Just my two cents, though....;D

PS: basic auth - hash and not provide login / password.

PS2: grab events on HC2 and pass to node-red it’s good idea... maybe... but I am think what initiator should be on node-red side plus node red must be as receiver.... and finally: Fibaro develop own API for end users that the end users afraid use it, isn’t it?! :)

@10der This looks like an amazing solution, but I'm new to Node-RED and mqtt and it would be great if someone could make a little guid. 

I already setup node-red and can controll my philips hue lights and installed mqtt mosquito and tested it with my pc, but somehow the connection to my hc2 does not work.

I get Error: getaddrinfo ENOTFOUND "username" "username":80

ok 10 sec is fine :) but it means that I need to push some events becouse scene would be to slow if i only get pooling every 10 sec. But first I will need to learn some node-red :)

yes, motion lights flow need 1sec poll circle... Just so long as FIBARO is not dead after DDOS pooling :)
