My Project

@jesus-cataluña Hi great work! Any chance for your sketch? There isn't many working sketches (without many errors in log) for home assistant. Unfortunately I can't write code.

@mfalkvidd Thank you the components just delivered some parts are still on delivery but i wanna ask the gateway thing on the smart plug i wish you can help me find a link where i can access it

@flopp Found one mistake. I wrote some Serial.print to see where in the code my problem was and I wrote in a wrong place, so the code was looping on a wrong way. When that was corrected I found out that my relay needed to get 1 when it was off, so I just changed to below and now I don't get a green light as soon as I power on the arduino #define RELAY_ON 0 #define RELAY_OFF 1

@nagelc Just ordered one of those buck converters from Digikey. Thanks for the suggestion. That might fix my whole issue.

@nca78 If you're talking about the basic motion sketch - I've tried it and it doesn't work The node checks in when initially powered but i can't seem to trigger it...

MySensors supports Lora (RFM95), so you could have the devices talk to a controller at home. As a controller I recommend the Mozilla WebThings Gateway :-) Less manual tinkering with config files. And yes, communicating with each other without a parent gateway is also perfectly possible. How about using sensors that are more robust than ultrasonic? There are some sensors used non-contact detection of water/gas levels, for example. if you want some GSM code, give me a shout.

Hi there! I have been doing some electronics and here is my thoughts about how to connect things. Any help will be very welcomed. My idea is to create a PCB after testing everything on a breadboard. [image: 1564422473670-irrigationmys-resized.png] [image: 1564422345375-hbridge-resized.png]!

@dbemowsk Thank you!

@tbowmo Thank you for your effort! Now my turn... the whole schematics of the d-diot board is available for download here! :wink: Of course I have to learn more and do some testing before implementing in the d-diot board the constant current source circuit that you suggested, but this a great option to eliminate the MP1584 (that one day may become unavailable on the market) and to lowering the cost. For the same reasons my plan is to substitute the step up module MT3608 with a boost converter circuit, made from standard passive components (like this). In any case, if someone else needs to make an universal IR remote with a Raspberry Pi, the configuration of the GPIO pins of the Raspberry is here, while the steps necessary to configure LIRC and lirc_web are here. The final results is this: [image: 1559765591483-screen1-resized.png] [image: 1559765616342-screen2-resized.png] Here the guides to play with the IR gateway (add a remote, clone a remote, Home Assistant integration)

@homer Glad that it helped! But make sure that RFLink supports your Watts Clever smart plug. If you already have an Arduino Mega and an RXB6 receiver at home is quite easy and fast to verify that. Another interesting option is that you can couple the Arduino Mega with an ESP8266 and then expose the serial output over Wifi with ser2net (see here) in the ESPEasy firmware. This other project goes further and use an ESP8266 to write the serial output of the RFLink to an MQTT server. Both solutions add flexibility to the positioning of the RFLink module in your home.

@homer This is how I do it: First download the latest Mozilla WebThings Gateway image and burn that onto an SD card. Their guide will explain how to 'burn' it onto an SD card. Insert it into the pi and boot it up. After a while you will see a new WiFi network for the gateway. Connect to it and follow the steps. You can skip the step to make a subdomain at Mozilla. Once done, open gateway.local in a browser that's on the same wifi network. You should now see the Mozilla Gateway interface. Under settings -> development enable SSH. Open a terminal window and SSH into the device. Google how to do that. For linux/mac it's something like: ssh pi@gateway.local and then enter the default password raspberry. once logged in, you have to install PHP. sudo apt-get install php5-fpm php5 -y Next, copy the Candle Manager from Github onto the Pi. git clone https://github.com/createcandle/Candle-manager.git chmod +x ./Candle-manager/start.sh ./Candle-manager/start.sh Now you should be able to go to gateway.local:8023 to see the Candle Manager. By default it comes with only one demo sketch. In the future you will be able to install a lot more. Arduino Sketches have to be properly formatted and placed in the 'sources' folder to be automatically presented in the Candle Manager interface. Examples of such sketches can be found here. Basically, the variables that you want to be modifiable via the interface have to be placed in a special section. The description at the top of the sketch will also be shown in the interface. For example: /* * * Temperature and more sensor * * This device can measure: * - temperature * - humidity * - airpressure (barometer). * * * * SETTINGS */ // You can enable and disable the settings below by adding or removing double slashes ( // ) in front of a line. #define HAS_DISPLAY // Did you connect a display? //#define FAHRENHEIT // Do you want temperature measurements to be in Fahrenheit? //#define MY_SECURITY_SIMPLE_PASSWD "changeme" // Be aware, the length of the password has an effect on memory use. /* END OF SETTINGS * * * */ // The actual sketch and other variables are placed here.

How much power are you feeding the sensor? I've had issues when I've fed too little power and it's resolved once I use more power.

@peter-gonczy I'm only a noob, but is that the whole sketch? Doesn't it need to be setup so it talks to the gateway?

Thanks. Everything is ok. I now have a node with 3 push-buttons for 3 colors settings and vocals commands for lazy persons or Tony stark. It's for a Iron Man reactor with neopixels... I wanted to Say : "Jarvis.. Iron Man laser" to have flash effects with neopixels. For this i use mysensors + jeedom + Google Home mini + ifft. Need to had Wait(200) in my loop to be sure to receive message from gateway. Thanks again
