Mikrotik and Home Assistant

A friend of mine remembered me of the Mikrotik addons in HA.
I forgot all about this.

I’ve got two integrations running. (Installed via HACS)

Don´t forget to enable the API on your devices.

/ip services
set api disabled=no port=8728

The addons/integrations extract a lot of information from the MT devices.

This integration will also let you know that your MT Router can be updated.

This is part if the presence detector/Device locator.
My roaming wifi network will give false locations. My laptop never left the same spot!

I will add to this page, after testing for a while

Domoticz + NodeRed + HomeAssistant MQTT

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

RFXCOM 433 Mhz

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

Temperature Humidity Sensor

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

Home Assistant/NodeRed update

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

mqtt:
 broker: mqttbrokerserver <--- still errors on this part, 
 discovery: true   <--- but where to configure?
 light:                             <--- Moved this under mqtt
  - name: "KitchenOutside"          <--- added a dash
    payload_on: "99"
    payload_off: "0"
    unique_id: "KitchenOutside"
    brightness_scale: "99"
    brightness_state_topic: ha433/kitchenoutside/brightcontrol

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)
