UPDATE 20240122 : below

I’ve got my RFXCOM connected to my Domoticz, and not connected to my HA.

To have the changes of my IOT devices being known to HomeAssistant I wanted to use mqtt.

Domoticz writes the mqtt topic (payload) like this
(topic: domoticz/out)

{
	"Battery" : 100,
	"LastUpdate" : "2022-11-17 18:21:59",
	"RSSI" : 6,
	"description" : "",
	"dtype" : "Temp + Humidity",
	"hwid" : "4",
	"id" : "230E",
	"idx" : 8461,
	"name" : "Living Temp/Hum",
	"nvalue" : 0,
	"stype" : "Cresta, TFA TS34C",
	"svalue1" : "20.0",
	"svalue2" : "60",
	"svalue3" : "1",
	"unit" : 1
}

So you can’t see which device it is by the topic name, the idx is in the json (8461)

To get this device ( a temperature sensor) into HA using mqtt i rewrote the mqtt topic using NodeRed

NodeRed flow

        "willTopic": "",
        "willQos": "0",
        "willPayload": ""
    }
]

The function node code ( rewrites the mqtt topic)

var varidx = msg.payload.idx;
msg.topic = "home/"+varidx+"/payload";
return msg;

Now we have a idx separated payload “home/IDX/payload”
(The other entries svalue/nvalue are from testing.

Adding the MQTT entries to HomeAssistant configuration.conf

mqtt:
 sensor:
  - name: "LivingTemperature"
    state_topic: "home/8461/payload"
    unit_of_measurement: "°C"
    value_template: "{{ value_json.svalue1 }}"
  - name: "LivingHumidity"
    state_topic: "home/8461/payload"
    unit_of_measurement: "%"
    value_template: "{{ value_json.svalue2 }}"

Now i can add the card to the dashboard.

This should now be a generic mqtt translator

A quick update:

Adding a motion sensor:

Home Assistant
  - name: "LivingMotion"
    state_topic: "home/45/payload"
    value_template: "{{ value_json.nvalue }}"

Add sensors to be reset to the switch node

UPDATE 20240122

I’m using domoticz as a 433->mqtt bridge, and some virtual devices i can toggle with curl (bash scripts)

I needed to make a custom 433 door sensor in Home Assistant with toggles to OFF after a few seconds. (There is NO off signal in this cheap sensor i’m using)

I’m changing the payload complete, to have a payload which matches the device class for door: (state with on/off)
It was nvalue = 0/1

(Whenever the IDX changes, I only have to update this Nodered part)
HA won’t notice the change.

var nvalue = msg.payload.nvalue;
msg.payload = {};
if(nvalue == 1)
{
msg.payload.state = "ON";
return msg;
} 

AND after 5 seconds

msg.payload = {};
msg.payload.state = "OFF";
return msg;

HA Part : Instead of the generic setup above (Old post part)

mqtt:
 binary_sensor:
  - name: "FrontDoor"
    state_topic: "home/frontdoor/payload"
    value_template: "{{ value_json.state }}"
    device_class: door

Upgraded the 2nd (Main) nodered machine to 3.0
Now the node-red-contrib-home-assistant-websocket nodes work again.

Also updated HA, and added some iframes using below.
The HA update broke my mqtt lighting due to changes in the code.

Below also in the example some iframe entries.
( When adding grafana, you need to change grafana.ini

allow_embedding = true

HomeAssistant add long-lived access token:

Click you profile icon bottom right
Scroll all the way down and press create token

Node-red

Add a HA node to a flow, double click and add a server with the little pencil

Base URL is important, you can’t just add http://internalip:port
Use a the URL configured in HA (config/network)
