I'm going crazy, any help appreciated.

My setup.
Pi 3 controller on ethernet.
HASSOS recently installed.
MQTT.
NodeMCU 09 wifi gateway.
My sensors switch / lamp.

Nodes and gateway talking fine. Controller and gateway register with MQTT server on HA (mosquitto).

Nodes are registering with gateway but not getting 'initial value' back from HA and repeats request.

This happened after I updated HA. Any help appreciated.

my problem is that the temp shows ok, the switch sends commands when tripped but is not on the Home Assistant UI or in entities. I need this switch to show up to set triggers.

Any help appreciated

This is the mqtt log for one on / off cycle.

Here is the most basic sketch I could find and tweaked the code to run as a toggle on a domestic light switch.

#define MY_RADIO_NRF24
#include <MySensors.h>
#include <SPI.h>
#define MY_NODE_ID 25
#define OPEN 1
#define CLOSE 0
#define switchpin 3
int oldvalue = OPEN;
MyMessage msg(MY_NODE_ID, V_TRIPPED);
uint8_t value = OPEN;

void setup()
{
  pinMode (switchpin, INPUT_PULLUP);
}

void presentation()
{
  sendSketchInfo("TESTER", "");
  present(MY_NODE_ID, S_DOOR);
}

void loop()
{
  if (digitalRead(switchpin) == !oldvalue)
  {
    value = value == OPEN ? CLOSE : OPEN;
    send(msg.set(value));
    oldvalue = value;
  }
}

With this code alone,no yaml entry, the node is found by HA and shows accordingly as triggered if the switch is flicked. mqtt all good, gateway happy.

How the fook do I attach switch result to the intended node?
Do I need a yaml entry for the physical switch? I tried but failed.
Do I then need to set up a trigger?

switch:
  - platform: mqtt
    name: "TESTER"
    command_topic: "mygateway1-in/2/2/1/0/2"
    payload_on: "1"
    payload_off: "0"
    optimistic: false
    qos: 0
    retain: true

This just gives me a new (software) switch in my dash and controls the light but physical switch (node 2 child 2) doesn't work.

Hello mate and thanks for chirping in. I realised a while ago that this project was well above my current knowledge base but thats like a red rag to bull, stubborn old git that I am.

After I got my HA, mqtt, MySensors and the gateway talking, my first few nodes found and set themselves up pretty much. I didn't have to jump into message construction, pub/sub, complex yaml code and that's the bit I'm stuck on. Once I get it, I'm away, the penny just hasn't dropped yet.

I think I need a night in, just me and mqtt, a nice meal, a bottle of soco, a few cuddles and really get to know each other. I guess thats true cyber sex, i do have a wife and kids.... honest.

Any reccommended sites, tutorials will be appreciated.

Cheers

This is the yaml entry for mqtt switch from HA website

switch:
  - platform: mqtt
    name: "Bedroom Switch"
    state_topic: "home/bedroom/switch1"
    command_topic: "home/bedroom/switch1/set"
    payload_on: "ON"
    payload_off: "OFF"
    optimistic: false
    qos: 0
    retain: true

There is no similar refence for mysensors switch section.

It's hard to ask when your not sure what your asking for.

I did have a look at that I assume I would need to insert a trigger also. It all seemed a bit over the top for the simplest of operation. All I want is if pin 3 goes high, publish light on.

The bit I can't get my head around is that there is no details of topics etc to establish what goes where. Because I don't know, it is all a bit 'magic' how the communications work.

Once again I must be missing something. Nowhere can I find and example of a simple domestic 240v light switch and light fitting.

I have lights on my HA, can control them with PC, phone, ALEXA, no problem, but I want manual switches (wifi) on the walls also.

I use the relay sketch for the light fitting side, all working fine.

Can I find anything relating to the switch side..... naffink.

I have built the hardware, arduino nano,NRF2401+ all sat on the back of a single UK light switch. Thats all good and tested also. It's the code I dont have or guidance to set it up.

Lights, temp, alexa were all basically plug and play with minor tweaks, this, a most simple use, baffled again.

Please help.

Well, the sun shines on a dogs arse some days.

We've only gone and done it, HA dash with relay sw. can controll led from dash. I honestly have sticky stuff running down my leg. You have no idea how happy I am.

For future reference.
I was flicking the power to reset pi in between config changes. My mosquitto was not starting from boot, so nothing to connect to, hence the errors when the code was right.
Also reset your nodes after a change.

This my yaml for the following setup

nodes are arduino nanos with nrf2401+ radio. (mysensors 2.0)

gateway is esp8266 NodeMCU 1.09. Wifi with NRF2401+

Pi 3 hosts Home Assistant and Mosquitto broker. Installed with All in one image.

mysensors:
  gateways:
    - device: mqtt
      persistence_file: '/home/homeassistant/mysensors4.json'
      topic_in_prefix: 'mygateway1-out'
      topic_out_prefix: 'mygateway1-in'
  debug: true
  optimistic: false
  persistence: true
  retain: true
  version: 2.0

mqtt:
  broker: localhost
  port: 1883
  client_id: home-assistant-1
  keepalive: 60

Righty. I'm off to play. Be back very soon when i get stuck.

Cheers for now fella, thank you for all your help.

OK. we are in, no errors in HA but have this in HA log.

Same same, no different i'm affraid. It's pissing me off now, more because I don't understand enough to do more for myself. I think this is going to be shelved for a while.
I am talking about the wifi gateway,

I am gonna stick with HA and mysensors but rehash my hardware. I have PI's , Nano's, Yun, Mini's and ESP8266's. What combination / configuration would you recommend for ease of setup.

Gonna try running mosquiito on a seperate Pi to HA first off.

Should my gate gateway sketch have presentation details in it, coz it doesn't. I removed comments to reduce size.

Invalid config
The following components and platforms could not be set up:

    mysensors
    mqtt

Please check your config 

To clarify in my head, everything that is connected to HA needs a block in config with minimum set of data but can be finely tuned with further commands if need be.
If this is the case, how is the gateway identified in the first block of code.

To make sure I am not mis-reading debug, this is my arduino nano node

Good morning from blighty. I retained your format and indentations, I think. Sorry for typo's, it was 1am and a few southern comforts. The hidden .homeassistant folder, was part of install and is where my config file lives, is that not good.

You are exposing my dumb ass here lol, i thought we just configured the '-device :mqtt'.
This is from HA website for mysensors but all I can see to configure is the boker IP. I tried it along with the previous code.... same error.

Where I come from, it's rude not to accept a drink between men and I don't mean a virtual drink. Your service and assistance is invaluable to me and the least I could do is slide you a bottle of Southern Comfort. So stop being humble, stop being rude and email me an paypal addy.

looked for a path to certificate...... no idea there. Tried leaving in and without

my mosquitto mqtt has no username or pw at the moment. Tried leaving in and without.

Once again I am at your mercy lol
