MySensors, Not sure the plugin is correct / device not working?

---

Hi, I built my first mysensors device… Go me!

The only thing is, I can’t get it to work in pimatic. I am sure the device is working. The setup…

• Device built, Arduino mini and example sketch (https://www.mysensors.org/build/humidity) - humidity sensor (pin 3 - sketch changed to reflect this after conflict with radio) and radio (pin 2) https://www.mysensors.org/build/connect_radio

• The device debug shows its working fine…

• The Pi is configured using this https://www.mysensors.org/build/raspberry
  Note: sudo cat /dev/ttyMySensorsGateway shows output…

  2;255;3;0;6;0

  2;0;1;0;1;36.0

I do not know what to do next. I do not know what device / node ID to configure in Pimatic and the auto discover does not pickup my device. Question is: Are my results above expected?

I suspect I have configured the plugin wrong somehow… Config is below…
{
“debug”: true,
“driverOptions”: {
“serialDevice”: “/dev/ttyMySensorsGateway”,
“baudrate”: 115200
},
“startingNodeId”: 3,
“plugin”: “mysensors”,
“active”: true,
“driver”: “serialport”,
“protocols”: “1.4.1”
}

Could someone suggest how I trace the problem better? Should I be seeing debug messages in Pimatic?

@gally789
I don’t know if there is any difference when connecting the Nrf-Radio directly to the Pi, most users I saw here use an Arduino as Serial-Gateway via USB connection. Ofcourse it’s smarter with direct Pi connection, but maybe have more side effects with CPU Power and other things. Either I don’t know if the protocol is really 1:1 and usable with PI + pimtaic in combi.

My Config (with Arduino on USB>PI and nrf24l01+ Radio) looks like this:
(you could already change protocol to 2.0.0 as you intend to only use MySensors 2.0 devices)

{
  "plugin": "mysensors",
  "driver": "serialport",
  "protocols": "2.0.0",
  "startingNodeId": 34,
  "driverOptions": {
    "serialDevice": "/dev/ttyUSB0",
    "baudrate": 115200
  },
  "debug": true,
  "metric": "M",
  "active": true
}, 

Your device looks great, the Node ID is = 2 , sensors 0 and 1 give already signals to the gateway 22.0°C and 36.0% Rh

Next step is to see if the debug output (look in my config) gives the same inside pimatic messages.
Go to “messages/Nachrichten”, activate debug messages and filter to pimatic-mysensors.
There should be an output already. Maybe restart the Pi before looking this, sometimes after testing other things there maybe no connection from pimatic to the gateway (service on pi).

@DDNRN Thanks for the message, I suspected the device was OK. In the debug I get only one message…

info [pimatic-mysensors]: Connected to MySensors Gateway.

Its like the plugin is not listening on the device at all.

@gally789
mhhh.
Any chance to check it with an arduino as gateway, whats like standard for now?

Did you activate debug messages in config as i pointed and did a restart?

@DDNRN I got an old nano out the cupboard just now, set it up with the gateway (ttyUSB1 as I already have an RF gateway).

I copied your config… changing the serialdevice for sure…

{
“plugin”: “mysensors”,
“driver”: “serialport”,
“protocols”: “2.0.0”,
“startingNodeId”: 34,
“driverOptions”: {
“serialDevice”: “/dev/ttyUSB1”,
“baudrate”: 115200
},
“debug”: true,
“metric”: “M”,
“active”: true
},

Now I get output from the new device from command line, but still nothing from debug…

Sure its a problem with my plugin somehow

your gateway is working fine. I think it is not auto discovered because your startingNodeIdis 34 and your node id is 2.
You could create a sensor in the GUI. So add a device, Mysensors Multi for example. Be sure to change the nodeid to 2 compared to the example below. And check the sensorid’s (to the child id’s)

This is how the config looks like

and humidity

@rikki78 Thanks, now I converted it to the USB gateway and reinstalled the mysensors gateway to reflect this it comes up in the debug log. I also set the startingnodeid to 1 but it still does not autodiscover??

I added the device manually (had changed to id 3 in last debug messages) and it works OK now with your instructions - Thank you!!!

The display is not as pretty as the RF temperature sensors (no mini graph) but it works as expected now otherwise… just need to work out why auto discover does not work.

@DDNRN @rikki78 Thank you both for your input, been a great help.

you’re welcome!
To enable the minigraph add the xAttributeOptions and tick ‘sparkline’

@gally789

… just need to work out why auto discover does not work.

Sometimes very curious, for me it only worked if I used a standard Sensortype with a new! NodeID higher than actually configured StartingNodeID-value in config and need to power on the device for the first time in the same moment when pimatic is already searching for it.
Looks like discovery is only working for the moment if the node is asking for registration from the gateway/pimatic-mysensor.
StartingNodeID-value is increased every time after new node is detected.

@gally789
Now, with working config, could you check if your first gateway (with direct radio connection to the Pi) will also work?
Would be intresting to have another option without separate arduino and see if there are other problems with this.

@DDNRN yep will take a look when I get some time. The Christmas holidays are over for me

@DDNRN

I had some time today to setup this on the RPi instead of an arduino nano gateway. I didn’t do anything special so the exact failure mode last time was beyond me - maybe it was just approaching it again with a fresh head!! Anyway, here are the steps in case anyone is insterested…

First I removed the serial nano gateway from the PI and uninstalled existing mysensors gateway info from the mysensors folder on my PI
sudo make uninstall

Then I configured as follows from the mysensors directory (standard mysensors config…)
sudo ./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway

I built it…
sudo make

Then I tested it. This showed the output from one of my custom sensors… (restarted sensor to ensure it would register)
sudo ./bin/mysgw -d

I then ran pimatic at this point, configured the plugin as follows…

{
  "plugin": "mysensors",
  "protocols": "2.0.0",
  "debug": true,
  "startingNodeId": 1,
  "driverOptions": {
    "serialDevice": "/dev/ttyMySensorsGateway",
    "baudrate": "115200"
  },
  "metric": "M",
  "active": true,
  "driver": "serialport"
}

I verified I could see the mysensors information in the messages screen with debug enabled.

From here I was happy it was working OK so I took the steps to install perminently…
sudo make install
sudo systemctl enable mysgw.service
sudo systemctl start mysgw.service

Restarted pimatic again…
Then checked the messages screen with debug enabled.

Now my setup is working 100% and I can have my spare arduino nano back

@gally789
Very interesting and congrats’ for the success. Maybe I will also switch over to this option later, don’t like all the different arduinos, one for each protocol is a bit too much in my eyes.
Maybe you can drop some more info later, after a couple of weeks collecting some issues or pro/cons for this solution.
Actually my system with nano is very stable, but only if I don’t use to much traffic.
