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

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?

@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?

@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?

@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.

@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?

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

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] Trying to connect to /dev/ttyACM0

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:

mysensors:
  gateways:
    - device: '/dev/ttyACM0'
      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.
