Thanks, at least one of the nodes started working!

Will try to update another one today.

Hi!

I just migrated my Home Assistant from RPi to VMware vsphere virtual appliance. I didn't get the current Arduino Uno serial gateway to work via passing through the device in VMware (Zigbee stick works great this way).

So I did a ESP8266 gateway since I had a board available. I got it flashed and I think the ESP talks with radio and HA talks with the gateway but my nodes won't work. I tried to remove the .json file, no help (just removed the entities from HA).

All I get in serial monitor of the gateway is this (over and over):
gwt:rfc:c=0,msg=0;255;3;0;2;

What should I try next? All my nodes have statically assigned node ID's. I'm not 100% sure what the version of mysensors they have but I think it is 2.2.something

How should I handle in code the issue that my relay is active when pulled to the ground (logical 0) and in Home Assistant it is the opposite.

Hi!

Going through examples and forum topics I've noticed that I'm using the wrong S-type and V-type.

I'm writing a new version of the code with S_LIGHT and V_LIGHT so there is now dimmer functionality (which I don't need).

Let's see if this helps.

Finally! Thanks @Boots33 !
I think mysensors is a great platform but simple tutorials are needed.

Hi!

I'm building my first mysensors node and have one problem before I can move it to production. The node is referred here: https://forum.mysensors.org/topic/9863/my-very-first-mysensors-node/3

It works perfectly reading temperature, humidity and the door status.

But with the light switch if HA goes to a state where light status is "on" but brightness is "0" it doesn't respond until I manually set the brightness to "100". I tried this with mysensors library version 2.3.1 and 2.2.0 but the behaviour is the same. My gateway version is 2.1.0

Here is the code for the node. There is nothing special on HA end. I'm running hass.io latest version 0.84.6 and lovelace GUI. Sorry for the comments in the code, they are part english and part finnish :)

Just this issue to solve and one package from China and I'll get the power supplys and nodes ready. Then pretty soon I'll have 10 mysensors nodes running! I already started with some Sonoff's in the middle froor, four now installed and one waiting for a suitable application.

Yes I know its possible with ESP8266 but I want to do it with a mysensors node. Any ideas on how to execute it?

Misna

Hi!

I'm starting my home automation journey and the architecture will be autonomous mysensors-nodes also controlled by Home Assistant.
Maybe some sonoff's for some special needs.

My house has 3 floors and the middle floor is 100% renovated 5 years ago so there I have to make compromises but the other two floors we are renovating and also recabling all the electrics so it's easy to get all cables routed to a central place for automation control.

I already have Home Assistant running a few months and its collecting sensor data from my geothermal heat pump, UPS device and some software running on my home server.

This first node is a kind on POC and wife approval node. It goes to a hallway in my basement which we are renovating at the moment.
The node has:

5V power from the AIO (maybe I'll need a fuse? or this https://www.openhardware.io/view/504/HLK-PM01-breakout-board)
Arduino Pro Mini 5V for the brains
NRF24 radio
DHT22 for temperature and humidity
A relay to control lights
Standard Finnish light switch (existing one)
Hall sensor for laundry room door

The idea is to make the system fault tolerant and not dependant of Home Assistant which I have to update from time to time and which runs on RPi3 which can fail.

Other nodes I'm planning:

Water pump monitoring and control
Electricity monitor
Freezer monitoring
Laundry room machines monitoring
Lights inside and outside of the house
Temperature sensors to all rooms
Control of under-floor heating valves (21 at the moment)

Hi!

I would very much like to use addressable RGB LED strips with fastled-library like Ben is using here with ESP8266 https://www.youtube.com/watch?v=9KI36GTgwuQ

I really have no idea on where to start. I guess its easy to switch on/off the strip but how am I able to change to different fastled-modes?

Misna

@gohan ok but at the moment the gateway runs on Arduino Uno. So I have to switch to RasPi?
Or can I buy another Uno and use RFM69 with it? But does Home Assistant support multiple MySensors gateways?

Misna

@skywatch So I would have 2 gateways? One for indoor sensors and one for outdoor sensors?

Would it be possible to have NRF24 and RFM69 chips on the same gateway?
So I could use the RFM69 with nodes that are farther away?

Misna

@skywatch There is maybe 30m between the buildings and the gateway is on the other side of my house so 10m of indoor space and lots of walls...

Yes the gateway has the PA LNA version. I guess it's ok to mix these?

I'm taking 5V from the UNO to RF module via this adapter: https://www.aliexpress.com/item/New-Socket-Adapter-plate-Board-for-8Pin-NRF24L01-Wireless-Transceive-module-51/32655936568.html?spm=a2g0s.9042311.0.0.IAzDGk

I'm planning to maybe place a couple of nodes to the outside wall of my house so maybe using these as repeaters might solve the problem..

At the moment I only have one PA LNA version but I'm about to place an order this weekend.

Misna

@martinhjelmare ok, I'll get a proper power supply. I have a capasitor welded to the radio module. The gateway has the model with the stick antenna.

I have tried how far the demo sensor node works (it has the std module with the antenna on the PCB) and it works anywhere in my 3 story house.
But when I moved it to a building next to my house it didn't work. The distance was maybe 40m.

Should I experiment with the setting #define MY_RF24_PA_LEVEL ?
What does this require from the HW?

Misna

@martinhjelmare The gateway (Uno) is powered from the USB port of the RPi3 which runs Home Assistant. Should I use a external power supply?

Misna

Hi!

I managed to get the node to work by rebooting everything. Maybe the controller and gateway must be alive before the sensor send its presentation?

But thanks for the help anyway!

I'm exited to start building my homeautomation now that I have all the connection working from end to end.

The first task is to replace my room thermostats with intelligent ones but I think I'll continue it in a different topic.

Hi all!

I'm just about to get my first sensor readout to Home Assistant but something is wrong and I need your help.

I now have Home Assistant running on Raspberry Pi 3 and an Arduino Uno acting as a serial gateway flashed with the example gateway sketch. And one sensor node on Pro Mini with DHT22 attached and flashed with the example DHT sketch.

From examining the logs I can see that Home Assistant is able to connect to the gateway:

2017-11-14 22:35:03 INFO (Thread-13) [mysensors.gateway_serial] Connected to /dev/ttyACM0

And I can see that the gateway is talking to Home Assistant

Here is my HA configuration:

      baud_rate: 115200
      persistence_file: '/home/homeassistant/.homeassistant/mysensors2.json'
  optimistic: false
  persistence: true
  version: 2.0
  
logger:
  default: info
  logs:
    homeassistant.components.mysensors: debug
    mysensors: debug

And the contents of the "mysensors2.json" persistence file

{"0": {"sketch_name": null, "children": {}, "sensor_id": 0, "battery_level": 0, "sketch_version": null, "type": 18, "protocol_version": "2.1.0"}}

So what should I investigate next? Is there perhaps something missing from the example from https://www.mysensors.org/build/humidity ?

In the example there is defined only child ID's not the node ID's. Shouldn't these come from the controller (HA) ?

Thanks for your help, I hope you my explanations make sense.

Hi!

This project has been on hold since I burned my FTDI adapter. Back to you in a few weeks when a new one arrives from China :)

Misna

Yes I have. When I upload the sample scetch from HA site I get this from serial monitor:

Now I have no idea where to start debugging this. In the scetch there is some lines that should print status messages to serial line but I can't see any of those.

What should I check next? I don't know if the node even has radio access to the gateway.

Misna

Hi!

Thanks to great help from the community I've managed to set up an ethernet gateway using Arduino UNO and a W5100 ethernet shield.

Now I'm building my first sensor node based on Arduino Pro Mini but I have no idea on how to proceed. I'm using Home Assistant as my controller.

I've made a sample sensor assembled with dupont cables to test different sensors before building real nodes. I am able to program it with the FTDI adapter but have no idea on how to present it to Home Assistant or even know if its communicating with the gateway.

I couldn't find a tutorial online on how to integrate MySensors and Home Assistant, please help.

Here's a picture of my POC sensor node (a cap to the radio module will be soldered today after I visit the local electronics store to resupply my stock).
