Home Assistant - How to recognize MySensors nodes

martinhjelmare

Hi!

I also want to try the MQTT gateway together with HA. MQTT support is well supported in HA, and looking at the MQTT protocol in mysensors dev branch it looks promising. I have just got some ethernet modules and more nanos, so as soon as I find some time, I'll get started. We can post our progress somewhere here whoever gets it going first.

Sounds like an interesting idea to me. I have never used a MQTT gateway before, so i'm going in a little blind. I think I have the server so far (mosquitto) running on the same RPI as my HA install; so now looking into the next step.

One thing though, would this replace my current serial gateway, or be an addition to it?

I've been trying to get MQTT working using the Dev branch here (http://forum.mysensors.org/topic/2352/guide-setting-up-and-testing-mqtt-client-gateway/) and have my configuration.yaml file looking like this for my W5100MQTT broker:

#MySensors MQTT Test
mqtt 1:
  broker: 192.168.86.198
  port: 1883
#  client_id: home-assistant-1
  keepalive: 60
#  username: USERNAME
#  password: PASSWORD

The Serial output from Arduino shows that I connected successfully

0;0;3;0;9;Starting gateway (RNNGA-, 1.6.0-beta)
0;0;3;0;9;Radio init successful.
IP: 192.168.86.112
0;0;3;0;9;Attempting MQTT connection...
0;0;3;0;9;MQTT connected
0;0;3;0;9;Init complete, id=0, parent=0, distance=0

But, Home-Assistant isn't registering the broker, and I have this error in the Dev section:

15-12-15 15:32:17 homeassistant.components.mqtt: Missing required configuration items in mqtt: broker
15-12-15 15:32:17 homeassistant.bootstrap: component mqtt failed to initialize

Does anyone have any ideas? @humblehacker @martinhjelmare @hek ?

Sorry, havent tried HomeAssistant myself.

drock1985

Thanks @hek , had to ask :)

Would it be possible to get a Home-Assistant dedicated sub-forum please?

martinhjelmare

@drock1985

What do you set MY_IP_GATEWAY_ADDRESS to on the arduino side?

You got it.

Thanks @hek very appreciated.

EDIT: Sort of ran into an issue with the Dev MQTTW5100Gateway sketch.... Thought the output I was getting above was good, but in reality the Arduino IDE wasn't giving an error. I decided to run the gateway in my RPI and view the data through SSH via screen. It initializes and shows the same data as the Arduino IDE, but then seconds later it dies and gives an error about screen terminating. Happens every time.

Going to try the ESP8266MQTTGateway: I'm got a hunch.

Does the IP address you defined in the config.yaml point to your Mosquitto Broker or the Arduino-Ethernet Shield? If it points to the Arduino afaik the point of the MQTTCLIENT Gateway is that it can be run as a client if you've already got a Mosquitto broker. Otherwise you would either need to remove mosquitto or forward it to a different port than the default 1883. If this was the case then HASS would be looking for a broker where none exists which is why it is missing configuration items...

For the time being, I'm thinking of taking a different approach with my toggle switch... I'm thinking of simply defining the button output as a binary sensor which can then toggle between two predefined scenes. At least in my case, input only needs to go in one direction so there's no need to receive any data from the controller....

@humblehacker

FYI, my fifo_queue pull request has been merged with dev branch at pymysensors, so I'm hoping to be able to implement switch support for the mysensors component in homeassistant very soon.

Thats great news! That should be a huge help with my plans for building an RGB Lighting controller based on the rotary_led_dimmer sketch! If I can ever figure out how to implement a simple toggle switch first...

@humblehacker

The configuration.yaml file I have pointed back to the local IP address, since Mosquitto and Home-Assistant are running on the same Pi.

So, you are saying that it should really be pointed back to the MQTT Gateway then? Still confusing to me.

humblehacker

Never mind then... As long as your using Mosquitto as your broker and the MQTT CLIENT Gateway (from the development branch) rather than the default MQTT Gateway sketch from- http://www.mysensors.org/build/mqtt_gateway then none of my earlier comments should apply... Basically I was saying that the default MYSensors MQTT Gateway is set up to function as a broker and would therefore conflict with any Mosquitto server running on the same port. The MQTT CLIENT Gateway (emphasis on CLIENT) from the development branch isnt set up as a broker so it shouldnt conflict with a Mosquitto installation.

martinhjelmare

It's still important to be wary about which ip address you assign where, so I think it was a good point.

drock1985

Well, I have Mosquitto and the Dev ClientMQTTESP gateway working, and is communicating fine. Now just trying to figure out the proper entry to add an item as.

drock1985

Ok, just got it all setup and working great now. Time to see how relays will work......

drock1985

Hey @martinhjelmare , I see HA was updated today; did your commits get added?

@drock1985

Hi!

No, I've submitted a pull request, but I need to fix some things, and maybe change some of it. But hopefully it wont take too long.

I have been trying to set up a switch in home assistant but I have had no luck in getting it to show up in the dashboard. I am using @martinhjelmare mysensors-component-switch branch of home assistant and the following sketch. Does anyone have any idea why this is happening? ```

/**
