I am playing with integrating HA with ClickPlus PLC via MQTT.
I have already established an MQTT connection. I can subscribe and publish to mosquito broker on NodeRED and PLC side
On the PLC side, I have logic for a simple light switch.
Now I want to create a switch in the HA dashboard, that when pressed, NodeRED will publish data to the broker to which PLC is subscribed and will change the output state based on received data.
I am quite a beginner with HA and have no idea how to approach the problem. Can’t find a way to create a custom entity.
Any help is much appreciated.
I’m not entirely sure what you’re trying to do but this might help point you in the right direction.
An entity node will let you create a switch in home assistant, you can use that to trigger your MQTT messages, it’s a switch so it’ll show as on or off in HA.
You could also create a “toggle helper” in HA and monitor that from Nodered for an on/off state, or create a “button helper” in HA for a momentary switch.
