Guys you are right is too early to quit , i have to try the RFM69 433Mhz as well before quitting , i was planning to wire my house with a 5v power supply to power all the sensors but i guess using a lower freq can help me to avoid that , will give it a try , lest just hope the rfm69 arrive, cuz i always have problems with evay ,
thanks guys you open mi mind one more time
well this is my project , right now im using 2 arduino nano with ethernet shield to read 3 lines Voltage on a delta instalation , 3 current sensors of 300amps for a motor , and 1 water pressure ,
all conected to a raspberry pi with domoticz
but yesterday i decide to change all , instead of 2 uno i will use a pro mini with a nrf24
so i desing two pcb

havent tested with sensors yet
but looks good so far
Sorry to replying in this old thread
Domoticz work pretty well on c.h.i.p. but not out the box we need to install a few stuff like java 8 git etc but I'm so happy is working just order two more c.h.i.p.'s as this small device is amazing and cheaper
well today finally i decide to change to c.h.i.p. as a controller with domoticz an amazing device but too bad for the product that got really bad customer support, ( if you planning to buy a c.h.i.p. read the forum first to get all the problems)
this is my controller using a chip, arduino nano
planing to chage the nano to a nodemcu
almost a year ago i was browsing on kickstarter when i saw the new micro pc C.H.I.P. from Next Thing Co. (www.getchip.com) , i order one just for fun 9usd + 6usd shipping , this machine took too long to arrive almost a year ,
but when arrive i get amazed of all the fetures that this $9 machine can do
1GHz Allwinner R8 processor
512MB of RAM
8GBytes of flash
Wifi
Bluetooth 4.0
video output (composite video)
linux debian distribution
CHIP is powered at 5V and draws about 500mA during boot,On the header terminals, we find a variety of power sources include 5V, 3.3V and 1.8V. The maximum current draws on these are 2A, 700mA and 50mA respectively
already included with a connector for a battery ( 1s) with " sudo battery.sh "we can have battery stats
BAT_STATUS=0
CHARG_IND=1
BAT_EXIST=1
CHARGE_CTL=0xc9
CHARGE_CTL2=0x45
Battery voltage = 3951.2mV
Battery discharge current = 0mA
Battery charge current = 510.0mA
Internal temperature = 56.8c
so i decide to make a controller for my sensors as i dont had a pi (to expensive for me :( )
so i decide to install mycontroller (mycontroller.org) it works pretty well but i decide to use Domoticz the installation for domoticz is pretty simple
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential nano cmake git libboost-dev libboost-thread-dev libboost-system-dev libsqlite3-dev curl libcurl4-openssl-dev libssl-dev libusb-dev zlib1g-dev python3-dev
mkdir ~/domoticz
cd ~/domoticz
wget https://releases.domoticz.com/releases/release/domoticz_linux_armv7l.tgz
tar xvfz domoticz_linux_armv7l.tgz
rm domoticz_linux_armv7l.tgz
./domoticz
and thats it
http://chip-ip:8080
domoticz is really nice controller i gonna test it for a couple of months.
also we can install node-red and johnny-five gpio for chip
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential
sudo apt-get install python
cd /tmp
mkdir node
cd node
wget https://nodejs.org/dist/v4.4.7/node-v4.4.7-linux-armv7l.tar.xz
tar -xvf node*
cd node*
sudo cp -R * /usr/local
cd /usr/local/bin
cd ~
mkdir node-red
cd node-red
npm install node-red
cd node_modules
cd node-red
npm install node-red-contrib-gpio johnny-five chip-io
node red.js
Go to http://chip-ip:1880 and play
i test node-red and works great
if you know how to use a pi you will know how to use chip
on the chip forum danjperron manage to add a nrf24l01 to the chip se meaby we can use a controller and gateway in the same device or make wifi sensors
https://bbs.nextthing.co/t/success-nrf24l01-on-spi-works/7919
@jkandasa so far so good need to buy extra sensors to see if this device can hold , but I'm pretty sure it will just like raspberry pi 1
And a few days later my pcb's arrived
Now to test the next version
@vikasjee glady but I follow some one else steps lol
https://bbs.nextthing.co/t/domoticz-small-how-to/2585
But instead of
wget http://domoticz.sourceforge.net/beta/domoticz_linux_armv7l.tgz
Just use
Wget https://releases.domoticz.com/releases/beta/domoticz_linux_armv7l.tgz
@mfalkvidd thanks mate that's exactly what I need
thanks guys , the solution for me was to add
ln -s /dev/ttyMySensorsGateway /dev/ttyUSB020
to rc.local
but i will try your idea @mfalkvidd thanks for the help
