MySensor on Hass.io - can't get it work

@maty said in MySensor on Hass.io - can't get it work:

e code isn't mine (made by my friend), I've been using it with Domoticz for almost a year, and it worked perfectly. But recently i decided to give a try to Hass.io, and I really like it. But I still have a problem with lights connected via MySensors (Arduino Mega conected to Rpi via USB), can't get it work with Hass.io. Config part in configuration.yaml look

Hi @MaTy
I have no experience with hass.io, but some comments arise.

Your configuration.yaml file path seems to be incorrect. You have to edit this to real path, something like "/user/.homeassistant/mysensors.json" or whatever. The path should exist, file there will be created if it is correct and writeable.
You should check if your USB port is really /dev/ttyUSB0 usually command "lsusb" is used, but I'm not sure how to do this in hass.io
Also, check if USB port speed is the same as in mysensors gateway and your configuration. 38400 seems different than the standard what usually is 115200 if I'm not mistaken.
EDIT: Ok, baud seems to match, so that should not be an issue.

Ad.1. I tried different path too (default one '/config/mysensors.json') - still wrong. I'm not sure how these .json files works, so maybe I'm still makeing sthg wrong. (Maybe someone can share me a link with an explanation or write a few words about it?)
Ad.2. USB is correct I checked (besides i have RFLink on the ttyUSB1 and it works great).
Ad.3. As You said at the end ... baud should be OK.

/config/mysensor

Default path seems to be generic and not really useful, at the beginning I had problems with understanding this as well. Take a look at the full location where your home assistant configuration files are located, this could be a good location. and add "mysensors.json" at the end (this file will be created and you can name it anything.yson).
like mine is "/root/.homeassistant/mysensors.json"

Wait, do I need to install an addon from reposytory, to make it work? Isn't it included in Hass.io? I cant see any repo :/

MaTy

I think i found the answer ... https://forum.mysensors.org/topic/7360/hass-io-and-ethernet-gateway-on-pi

It looks like I need docker add-on to run MySensors gateway on Hass.io, and it doesn't exist so far, what a shame :(

Tom Carpenter

I don't have a light switch on my sensors but I do have a couple of temp sensors running on my hassio installation with no problem.

MaTy

@tom-carpenter
How did You make it? Is it via serial gateway?

@maty

That thread is about attaching the radio directly to the RPi GPIO in combination with Hass.io. You're using an arduino as gateway that has the radio if I understand correctly. So you shouldn't need an addon for your case.

I suggest looking at the Z-wave documentation for Hass.io where they also connect a USB device. It's the same principle as the mysensors serial gateway when you use an arduino as gateway.

@martinhjelmare

Oh, sorry, im so confused after I moved from domoticz to Hass.io. But I don't need Z-wave. What I have is serial gateway based on arduino mega 2560, with a sketch (example) https://hastebin.com/cinokiraka.cpp which controles all lights in my house. The arduino mega is connected to my RPI3 (with Hass.io) via usb (ttyUSB0). It worked perfectly on Domoticz, all lights was discovered automatically. I've checked the documentation of MySensors implementation on Hass.io web site, and read plenty of forums and still nothing :/
I'm still getting errors. https://pastebin.com/VDaVRKkV

Are you sure that's the right device? It's /dev/ttyUSB0 that is the source of the error in your output. Maybe the device is something like /dev/ttyAMA0 or /dev/ttyACM0?

MaTy

@nelsonov
when i use "hassio homeassistant hardware" command it displays only ttyUSB0 and ttyUSB1. I have RFLink connected to USB1 and it works great, so MySensors gateway must be the ttyUSB0.
https://pastebin.com/wTn72d1D Am I right?

nelsonov

What do you get from ls -l /dev/tty*?

After I disconnected gateway and connected it again, I checked command "dmesg | grep usb" and this showed up
https://hastebin.com/leqocowaco.vbs before there was nothing after command. Command ls -l /dev/tty* still the same.

nelsonov

You might need to take this to the [Home Assistant Forum]
(https://community.home-assistant.io). Something strange is going on at the OS level. Your kernel is recognizing the USB device, but the OS isn't creating the tty. You can try lsusb just to see if it's still there, but beyond that I'm out of advice. The error you are getting from Home Assistant has awkward wording, but it means that it can't find the serial device.

@maty
If you read the Z-wave documentation I linked to you will get instructions how to add a specific USB device to Hass.io docker. My guess is this could solve your problem.

For some devices the /dev/ttyAMA0 device is not detected by udev and is therefore not mapped by Docker. To explicitly set this device for mapping to Home-Assistant, execute the following command using the ssh add-on:

$ curl -d '{"devices": ["ttyAMA0"]}' http://hassio/homeassistant/options

Replace ttyAMA0 above with the correct device in your case.

@martinhjelmare
I did It. resault But I'm still getting errors :/

I guess I'm hopeless. It's probably sthg silly as always.

update:
after trying different solutions i typed hardware check command and new serial appeared 'AMA0' but I did nothing physically with RPi (din't attach any devices). I tried to check mysensors config with ttyAMA0 instead of USB0, but I still got the same resault.
ps. of course when I was trying your command ($ curl -d '{"devices": ["ttyAMA0"]}' http://hassio/homeassistant/options), I did it with USB0 parameter, not AMA0.

Yesterday I accidentally restarted Hass.io with all that errors in config. I was afraid that it'll crush after restart but it actually worked. After restart I turned on switch on the wall, and Switch (light relay) appeared on Hass.io home screen.

There are still the same errors in config, and I have some issues with those light switches. Most annoying issue is that Hass.io doesn't update switch state after change via gui. Switch state changes in Hass.io when i use manual switch on the wall but when I use gui it doesn't

@maty

You should send feedback of state changes to home assistant from your device. This is done from the receive function. The switch in home assistant will switch as soon as the feedback comes in.

Also set optimistic to false in your mysensors config section.

MaTy

@martinhjelmare
You mean in my sketch, something like this?

void receive(const MyMessage &message) {
  // We only expect one type of message from controller. But we better check anyway.
  if (message.type==V_LIGHT) {
     // Change relay state
     digitalWrite(message.sensor-1+RELAY_1, message.getBool()?RELAY_ON:RELAY_OFF);
     // Store state in eeprom
     saveState(message.sensor, message.getBool());
     // Write some debug info
     Serial.print("Incoming change for sensor:");
     Serial.print(message.sensor);
     Serial.print(", New status: ");
     Serial.println(message.getBool());

I had optimistic set false.

BTW: Strange thing, baud rate in my sketch is 38400, but when I set it up in Hass.io, lights won't work, when I changed to 115200 in .yaml (in sketch is still 38400), all works fine, except the states update.
