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

@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

Smartclock based on timer based mysensors node, which fetches time in unix second from pimatic controller.

Smartclock made from following components.

1. 4 cascade matrix led 8x8.
2. DHT11 for temperature
3. Li polymer 4000 mh battery.
4. PIR sensor for motion detection.
5. Shuttle box..
6. misc..

SmartDisplay shows following info based on controller 's rules.

1. Time to office using bing map api.
2. Outside home temp, hum etc.
3. Online weather forecast information.
4. Any online information can be displayed like stock tick etc.

Smartclock clock has temperature sensor DHT11 and a motion PIR sensor to detect movement.

@karl261 using ButtonsDevice as mentioned by Oitzu, you can achieve the point no. 1 . non off/on switch..

{
      "id": "mode",
      "name": "TV Mode",
      "class": "ButtonsDevice",
      "buttons": [
        {
          "id": "PVR",
         "text": "PVR"
        },
        {
          "id": "HTPC",
          "text": "HTPC"
        },
        {
          "id": "Chromecast",
          "text": "Chromecast"
        },
        {
          "id": "testing",
          "text": "RainBowCycle"
        },
      ]
    },

for point no. 2 you can use pimatic IFTTT rules to control (*hidden * relay switch button) moreover you can switch off optocoupler after 50 ms using rules.

1. if you have some special requirement you are welcome to contribute..

@Oitzu sure will do it need some time..

New version of plugin available. 0.8.21.

and a video to showcase its capability..

found this library for scrolling effect https://code.google.com/p/arudino-maxmatrix-library/.

@GertSanders purchased it from ebay, yes inside it is mini pro and nrf radio module ..

My compact serialGateway with nrf201 long range , power indicator LED and USB cable connected to Pi.

@epierre .. nothing much .. used relay to control 2 devices and tried to calculate the power consumed ( in watts ) assume the input voltage is ~220v.

@hek and team. congratulation on new milestone.

using IR transmitter

I have gone through this link, and tried it recommendation of increasing the RAWBUF size and also used sample sketch which was not working for me , may be i was doing something wrong. Also, It uses raw IR signal and handling raw signal is not simple compare to IR hex code which are at max 32 bits. I wish IRlib, IRemote etc support handling of long IR signals. Any library which support it?

@Moshe-Livne the IR library i used is some how fails to decode and dump the AC IR signal received even after increasing the buffer size RAWBUF, not sure how broadlinks rm2 is working.. basically i used mini pro node as IR receiver/emitter .. the received IR hex codes ( bit, type NEC, etc ) are send to controller ( pimatic ) . Using pimatic Rules controlling electronic devices which sends IR hex code to node if rule is triggered.

Any one tried using IR transmitter to send IR signal to AC with mini pro ( 328p ) as mysensor node. I know mini pro have limited ram / rom support.

Note: AC remote send long IR signals which may not be completely captured by IR receivers connected to mini pro. may be one try on rasp pi but that's a last resort.

@Mad-Moo latest code 0.8.17 is pushed to github. now everything is sync.

newer version (0.8.15 ) of plugin release . support Acronym for devices . improves user experience.

think one of the nicest things about pimatic is the graphing functionality. I want to log and and check how the heating is distributed throughout my house and at which consumption depending on heatpump / woodstove set

since i don't have home laptop with me. otherwise , i could have shared the custom sketch with you. but what i remember is that it sends V_WATT message with wattage usage and calculate KW and KWh ( still broken ) at controller end ( pimatic ).

meanwhile, i'm fixing the pulsemeter code which will be compatible with actual sketch, wait for 1 or 2 days. Also, we will be able to see battery status (optional) with sensor devices.

one thing you missed here is that pimatic is browser based also have the "automation by rules" functionality which is awesome. also you can try various plugins available with pimatic. http://www.pimatic.org/pages/plugins/

@Fredrik-Carlsson

frankly, i couldn't check pulsecount using actual power meter. although i can simulate it . It's custom made according to my need. I can modify it as per http://www.mysensors.org/build/pulse_power build easily.

currently it only supports "V_WATT" message.

@Sebastien-Vayrette-Gavard said:

kindly change the "class" name as "MySensorsLight" . please note it has a 's' in between.

@HarryDutch

thanks Harry, definitely will try your suggestion of I/O pins as power supply.

@HarryDutch said:

f you really want to remove the regulator there are several ways to do this. Best way (at least for me) is first cutting the legs of the regulator with a very sharp scalpel. Be careful to cut only the legs and not the board beneath it. Then try to lift it from the board by using a needle nose pliers. Use minimal force! If you have to use too much force then try to cut the legs a little further.

So there you have it. First try to prove to yourself that it's possible to get current consumption for an Arduino Pro Mini down to a few microamps and only then continue your adventures in MySensors land! Hope this helps.

really nice explanation of using battery with the sensor node. actually, i'm using 9v battery with mini pro using regulator for measuring DHT22 data and ambient light. It's working from last month and results show may work 2 month more. the reason of using 9v battery is that i have handful of them.

Now, my question is that why initially the sleeping current is ~900 uA and then it boils down to ~120 uA after few day. why is that? . your expert answer will be appreciated.

@funky81

@funky81 said:i

nning below code : 3,86mA

i have a setup with temp/humidity/light with mini pro 8mhz 3.3 v and take around 120 uA in sleep mode

@Heinz

where are you storing the sensor data for presentation , stream. let me know which database you are using here? you can have another flows for sending the the request to sensor node via serial port. I tried it same some time back . may be i can share it here.

@jurasek connecting NRF24L01 to RPi directly is possible you will find good amount of references if you search this form.

@Vladut-Grecu said:

if state is true then _state = 1 else

check the pimatic-daemon.log file and what kind of error exception your are getting . not sure if you have enable the "logLevel": "debug", in config.json for pimatic.

Also, you need to add entry in device-config-schema.coffee schema file.
if nothing works share the log file with me..

I'm also new to coffee or nodejs and struggled a lot understanding the coffee script , basically, still in learning phase..

@Totche said:

0;0;3;0;9

these are log message from gateway .. may be your gateway is not able to send the response to sensor node..

@Ralf-H sure will add support for light sensor

@Kurtsejr try http://forum.mysensors.org/topic/797/mysensors-controller-plugin-for-pimatic/2

@ricardot added support for battery level stats 0.8.9

@ricardot

battery sensor visualization is WIP..

@gogomartin

Currently mysensors plugin only support static node id. Try configuring static node id in sensor code. Hint.. Gw. Begin (null, node id)

Let me know if it's works

Congratulation to the winners. good to see more and more people are getting interested in mysensors project ..

@tekka
Is OTA or MYS bootloader end to end working for you. if yes, let me know the steps that needs to be followed. i'm getting error in gateway where I_FIND_PARENT request(from sensor) response is failing and not reaching to sensor node. however, it works after fresh make load command issue..

@Damme Is OTA working for you..I am also getting the same message from Gw.

@hek said:

ok thanks.

@tekka need your help here...

not sure i'm missing something. getting following error while compiling MYSBootloader. OTABootloader working fine for me..

Any idea what is the difference between two bootloaders.

@ricardot

I have fixed the issues, plugin published to public npm registry . now i think it should work perfectly

@ricardot said:

atic] Cannot find module 'bluebird'

Later I added two devices, a PIR and a relay-switch, and I'm receiving this message:

13:46:49.305 [pimatic] no plugin found for device "PIR" of

give me sometime will fix this issue.

Since i haven't register mysensors with npm. that's the reason it is giving you the error. As a work around try download & manually installing pimatic-MySensors in node_module in pimatic-app folder.. Here other plugins are also installed like Pimatic-mobile-fontend etc.. Pimatic should be able to pick it up..
I will try to fix this issue meanwhile.

Let me know if it's works.

@axillent said:

re quite sufficient in packing all things together

thanks

here's the finished product

@doblanch i'm in process of completing the sketch and will share it with you once finished.

@EasyIoT .. good to hear you were able to run NRF24Lo1 with pi. it will good if you could share your setup. In my case was getting st=fail ack message many a times..

attempt over last week , circuit board with 2x relay actuator and hall current sensor ( acs712 ) and step down transformer. The most challenging part is how to pack your creation in a nice box.

agree with @hek. better go with serial gateway.. I had tried running NRF24 with pi. its works sometime and ack fails many a times. kind of one way communication from sensor to gateway.
Also, make sure you don't overclock your pi, if you want to give it a try.

Yet another serial gateway working without wires clutter.

@hek @bjornhallberg
added support for relay-actuator module

Module supported..
Temperature and Humidity ( http://mysensors.org/build/humidity)
motion ( http://mysensors.org/build/motion )
Relay-Actuator ( http://www.mysensors.org/build/relay )

Really nice... Gr8 work

@Fredrik-Carlsson Very nice . node-red give a non-programmer the flexibility to write the controller logic without going into the complexity of programming.

Created controller plugin for pimatic https://github.com/DheerajKhajuria/pimatic-MySensors

pimatic is a home automation framework that runs on node.js. It provides a common extensible platform for home control and automation tasks.

Uniform interface

It defines several schemata for different home devices and sensors, so that all devices can be controlled uniform and are presented in a common interface.

Automation by rules

Automation tasks can be defined by rules in the form of "if this then that", where the "this" and the "that" part can be fully custemized by plugins. See the rule page for more details.

Web-based interface

The mobile frontend plugin provides a nice web frontend with a sensor overview, device control and rule definition. The web interface is build using express and jQuery Mobile.

Extensible

pimatic is extensible by various plugins adding features and integrating existing hardware and software.

Steps to install pimatic

Now I would say let's begin with setting up Pimatic from scratch :

You can either check the instructions on the Pimatic website http://www.pimatic.org/guide/getting-started/ or follow these steps.

If you are using a Raspberry Pi, get the latest Wheezy Image or what ever you like from here : http://downloads.raspberrypi.org

Then write this image with this tool Win32DiskImager to your SD-Card.

Now set up your Pi with sudo raspi-config and do the usual updates with

sudo apt-get update
sudo apt-get upgrade
sudo rpi-update

You're ready to install Pimatic Go ahead with the following 19 steps :

1.) wget http://nodejs.org/dist/v0.10.24/node-v0.10.24-linux-arm-pi.tar.gz -P /tmp
2.) cd /usr/local
3.) sudo tar xzvf /tmp/node-v0.10.24-linux-arm-pi.tar.gz --strip=1
4.) sudo apt-get install build-essential
5.) mkdir /home/pi/pimatic-app
6.) cd /home/pi/
7.) npm install pimatic --prefix pimatic-app --production
8.) cd pimatic-app
9.) cp node_modules/pimatic/config_default.json config.json
10.) sudo nano /home/pi/pimatic-app/config.json (very important :insert admin password!!! otherwise pimatic won't start and comes up with an error message)

11.) sudo chmod 777 /home/pi/pimatic-app/
12.) sudo reboot
13.) cd ./pimatic-app/node_modules/pimatic
14.) sudo npm link
15.) wget https://raw.github.com/pimatic/pimatic/master/install/pimatic-init-d
16.) sudo cp pimatic-init-d /etc/init.d/pimatic
17.) sudo chmod +x /etc/init.d/pimatic
18.) sudo chown root:root /etc/init.d/pimatic
19.) sudo update-rc.d pimatic defaults

Now you are ready to start pimatic for the first time!
There are three ways to start pimatic generally.

Automatically at system start (since we daemonized Pimatic with the entries in init-d)
With the command sudo service pimatic start (will run Pimatic as daemon / service in the background)
With the command sudo pimatic.js (can be executed everywhere, since we globalized it)
For the first start i recommend to use option 3 since Pimatic will do some compiling and setting up things. this may take a while, so you are able to watch the debug outputs on the console screen and see what Pimatic is doing actually.
If you run sudo "service pimatic start" you won't get any debug messages since Pimatic will run in the background.

When Pimatic is through with all the setup stuff, you will see a message like that :

Now you can access the Pimatic gui via browser by entering the IP of your pi and go ahead with the further setup = > Step 2 - GUI overview

Any idea or try on integrating Node-red running on raspberry pi as controller with MySensors network. http://nodered.org/

thanks for replying and providing the guideline for newcomer.

Arduino IDE : 1.0.6 ( ubuntu 64 bit)
Controller Software : Nodejscontroller.js using nodejs & mongo db on raspberry pi.
Gateway : running piGatewaySerial code and connecting it to NRF24L01+ transceiver using SPI.
Arduino and Raspberry pi gateway code debug on..

I have two sensors in my network ( temp , Hum etc ) and motion detection. both working in auto mode and request node id from controller ( raspberry pi ) node via gateway . but unfortunately, response code of both nodes get same node id 1.

may be bug in sendNextAvailableSensorId() function response.
any idea?

Note: I know static node id will work. but Auto mode should also be working.
