Hi all.
I'm testing MySensors but don't use any Controller then I wrote my self easy utility for better understand Serial communication ..

program you can download from here : MySensor.zip

it's easy version serial terminal for MySensor .. not support Inclusion button .. etc ..

regards..

Hi. just for inspiration ..

my serial gateway :
USB is used PL2303SA
nRF24L01+ with PA

I mkae mistake .. must invert led .. and all will work.. for 100% ..

regards.

Hi.
One idea .. FIFO buffer for outgoing message..
low power relay node .. if use bi stable relay then is possible to power only from battery .. but radio must go to sleep.. then wake up every 5 or 10 second .. and ask gateway for new command ..
node just if wake up then waiting for example 0,5 sec for incoming message .. if not received then go sleep ..
gateway wait for node .. and if got command in FIFO for this node then send message ..
just idea..

Hi all.

I make my first project (thanks to all for help) Switch , with battery and temperature monitoring..

here is my node PCB :

and here is schematic :

and project :
BinSwitchBatSleep_ACK.zip

This project use two button INT0 and INT1 . if change state then send packet with ACK request .
if no ACK received then generate sound .. from piezoelectric generator .
Battery is in volate *10 - if received value is for example 28 it s 2.8V .

now working good .. power consumption is 7uA .

PS> I need help with pin change interupt .. I now use two button only .. but want support 4x button.. then need litle help how to use it ..

regards..

Hi all.
I make small project to controll 32 relay by I2C expander PCF8574 .
In my project are V_LIGHT for relay control and V_TEMP to define if want save relay state to eeprom memory or not .
if S_TEMP is 0 then after reset, all relay are close and clear eeprom memory for relay state , if S_TEMP is 1 then relay state are read from memory .. and save state to memory if change state of relay .

V_LIGHT not define if relay is open or close .. only change state from 1 to 0 , and 0 to 1 .
It's to control light in my house ..

PS: tested in Arduino Nano (china clone CH340 with micro USB ) , nrf24L01+ (PCB antenna) with 1x PFC8574
PPS: Node ID is manualy set to 58 if need change to AUTO
