My Project

I couldn't just lay down in the sofa so I started to test and now I got a code that seems to work. I have tested it for a few days and it seems to count correct. I made some changes so it will send data every minute and it will send Watt-value even if it is the same value since last time. I am using VAR2 for second energy meter since I don't know how to config Incomingmessage and seperate VAR1 from different Child_IDs. I change corrupted interrupts from 10000L to 40000L otherwise it reported interrupts twice. /** * 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. * * Created by Henrik Ekblad <henrik.ekblad@mysensors.org> * Copyright (C) 2013-2015 Sensnology AB * Full contributor list: https://github.com/mysensors/Arduino/graphs/contributors * * Documentation: http://www.mysensors.org * Support Forum: http://forum.mysensors.org * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * version 2 as published by the Free Software Foundation. * ******************************* * * REVISION HISTORY * Version 1.0 - Henrik Ekblad * * DESCRIPTION * Use this sensor to measure kWh and Watt of your house meter * You need to set the correct pulsefactor of your meter (blinks per kWh). * The sensor starts by fetching current kWh value from gateway. * Reports both kWh and Watt back to gateway. * * Unfortunately millis() won't increment when the Arduino is in * sleepmode.

@checkup if you add this project to openhardware.io including sources, schematics (if applicable) and some description we can import it to the build pages.

@clippermiami can you hit it from your house with a garage door opener? I haven't integrated mine into a HA controller yet, but for now I just have an RPi driving a relay board that is soldered into the guts from a garage door opener. Bonus there are three buttons so I can run both garage doors and the front gate from a web interface. I'm sure you could do the same with an arduino in place of the RPi.

sorted works a treat now. My bad, used a sketch I had tinkered with in the past. sketches melded now. Finished sketch below for them that might need.

I implemented this with a schneider PM9C using modbus which works fine Zigbee is just transport, shouldnt be to hard to translate.. You need the manual to see what data it provides, which i couldnt find online. The model you specified has been of the market for some years.

@AWI I have access to the necessary most modules and electronic components in my city . so if you have idea for this told me and i am ready to test .

I have a 0.4mm nozzle. I can print with a 100 microns resolution with this one 😉

Hi, It's hard to say right now. It can be interesting to know how do you control the On/Off. Those Ceramic caps don't like to be used without any liquid and can be damaged very quickly if there are dry. But normally there is a build in switch off circuit if no liquid is detected. Can you tell me more how to you modify the electronic to control it with Mysensors ?

@Yveaux Thanks. I used alcohol to put the silicone back. I have add that information in the post

The library for SI7021 is missing. You'll find it here: https://github.com/mysensors/MySensorsArduinoExamples

@Eawo Domoticz groups sensors after the order you present them in, see: https://forum.mysensors.org/topic/5132/ds18b20-ans-sht31-d-show-up-as-combined-sensors-on-domoticz/15 I send every 5 minutes and check the value before so that I only send if the value has changed I have been running my sensor for nearly 2 months now and battery level has only decreased 1-2% Make sure you use 1 MHz bootloader

Thank you everyone for your input on this. Eventually i just used a piece of wire 82mm long and bent it over and stuck it out of one of the slots in the housing. Crude i know but the initial results are promising. The Gateway is in one corner of the house upstairs and i placed the sensor in the opposite diagonal corner downstairs in the house through a guess of 4 brick walls and the sensor is reporting an Rssi of -65db ti -70db. Shame Rssi can not be presented in Domoticz properly yet (Having to use a dummy sound sensor to visualise it) as mysensors has no way of handling it yet!. I will be conducting more range tests but the change from NRF24 was well worth it (No more deadspots in the house).

Hi all, Just bought a little CNC + Laser engraver machine that I'm going to use for PCB milling and have some questians for the experienced users. @Frank-Herrmann will your Chillipeppr code work on all arduino/gcode based CNC routers? Any other free software like BamCam for use will small projects? What cutting bits are you using for PCB milling?

@sundberg84 Will look into that, i have a UNO lying around aswell so prehaps ill experiment with the bootloader burning eventually.

@alexsh1 Indeed, there is a solderpad near to the D2 pin which needs to be closed (connected) to allow the IRQ signal to go to D2, so one can use the radio

@vlad1 welcome to the MySensors community! Who are you asking? About which project are you asking? Can you post a link to it? If you mean this project, the code is right there in the first post.
