pimatic-mysensors controller plugin

[BastienVH]

Hi,

After using OpenHAB for quite some time, I've made the transition to Pimatic.
I've got a pro mini 3V running on 2 AA batteries with a DS18B20-temp-sensor.
I would like to be able to display the battery level but am having some trouble.
I combined the temp and battery sensor into 1, but the battery status isn't being analyzed properly.
When I restart the node it transmits a value of 12 and shortly after that a value of 0.

Any ideas how to solve this?
Is this related to pimatic and the format in which it receives battery data or is it simply a fault in my code?

Thanks in advance!

This is my code:

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

@BastienVH . check few things first.

1. hardware wiring is correct and as per mysensor guide.
2. what debug value "sensorValue" you are seeing on serial console if you debug your sensor node.
3. check the debug log in pimatic

[BastienVH]

@Dheeraj
I feel so stupid now... I built this circuit on a breadboard and after fiddling around with it yesterday, I forgot to place the resistor for the battery in the right pin. It was now on a different row.
Saw it and fixed it. Now I get a battery percentage in Pimatic!

Thanks for your help!

@karl261 Do you have any news ?
Which raspberry pi are you using ? PI 2 ?

I experienced the same issue with domoticz on raspberry pi2 + serial gateway with RFM69 radio.
I really don't think that the issue is the controller. It seems that the radio is stuck cause when I debug my node after reset, all outgoing messages are marked with st=fail meaning that radios can't reach each other.
I don't know if it's my chinese arduino nano or raspberry pi 2 usb power or my radio module.
Investigation in progress. Something a reboot is not enough, I have to disconnect usb cable in order to make it work again.

[karl261]

@fets Yes, indeed, I made some progress during the last weeks. Today I finally found a way to display these debug messages. Took me months. See this thread: http://forum.mysensors.org/topic/2392/how-to-properly-debug-serial-gateway-nrf24l01
I think my serial gateway was somehow badly connected. During the past weeks I verified everything, re-soldered, tested various power supplies and radio modules, etc. Now it seems to work usually stable. But not always. Now I am playing around with increasing the sending power of the radio modules.

I am using a pi 2.

Interesting, your problem sounds very similar. Unfortunately I do not really have any advice. Maybe try to build a duplicate and see if this works better?

[fets]

@karl261 My issue seems solve using capacitors on my rfm69 radios.

Hi everyone,
I installed Pimatic and it looks work just fine.
In the Config menu I added the codes below.
Saved and restarted the Pimatic.
I see "Light Unknown%" on the frontpage.
How can I fix that? Thanks....

@fahrettine How does your sketch look? Does pimatic receive anything in de log?

[fahrettine]

Hi,
Thanks for the answer.
1-I installed Pimatic.
2-I installed Serial Gateway on the Arduino Nano.
3-I installed the Light sketch from MySensors on the Nano.

Pimatic logs look like below. It seems it doesnt receive any signal.
I think there is someting wrong with the USB port...
Are my USB port settings coreect?
You can see MySensors plugin settings above.

You may want to double check that config.
It should be more like:

 {
   "plugin": "mysensors",
   "driver": "serialport",
   "protocols": "1.5.1",
   "startingNodeId": 1,
   "driverOptions": {
     "serialDevice": "/dev/ttyUSB0",
     "baudrate": 115200
   }
 }

if, ttyUSB0 is your connected arduino nano.

[fahrettine]

I plugged the controller and light sensor on my pc.
The controller receives and the sensor transmits signals.
So, the hardware is OK.
I changed the USB setting as "serialDevice": "/dev/ttyUSB0"
But still no signal.
Because I am new on RPi I cant set the USB corectly.
My USB settings (lsusb -t) are like below:
What is my USB port? USB0 or USB1 or other else?

pi@raspberrypi:~ $ lsusb -t
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=dwc_otg/1p, 480M
|__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/5p, 480M
|__ Port 1: Dev 3, If 0, Class=Vendor Specific Class, Driver=smsc95xx, 480M

dmesg | grep tty

Will give you an output like:
ch341-uart converter now attached to ttyUSBXX

[fahrettine]

Oitzu thank you very much.
I solved the problem.
It was the nodeID. I set the nodeID to on the sketch to 15 and the problem solved.
Thanks for your help...

[fahrettine]

Hi everyone,
I installed Pimatic. It works fine...
I installed light sensor code from MySensor: http://www.mysensors.org/build/light
Light sensor works fine...
After that I intalled the Relay code: http://www.mysensors.org/build/relay
The relay doesnt work!!! Any idea for the problem???
When I turn the buton On/Off I can see the sending messages on debug.
Thanks!!!
Below are my Pimatic Config codes and debug messages:

{
  "id": "Switch",
  "name": "Switch",
  "class": "MySensorsSwitch",
  "nodeid": 10,
  "sensorid": 1
}

check whether you received any message ( serialport output ) on relay sensor node.

[rollercontainer]

I've seen the "protocol" line. Is it suitable for 2.0.0beta sketches ?

[Sweebee]

@rollercontainer the plug-in works fine with 2.0. You dont have to change the protocol value in the plug-in.

[Redferne]

Is there any development of this plugin?

[ricardot]

@Dheeraj,

Do you plan to continue to develop this plugin? I will very pleased to see a mysensors button. Thank you!

I second this. And also see if we can lose the dependency on serialport 2.0.6 so that we can use Node.js > 4.9.1
