I have a serial gateway. I've talked about wi-fi only for comparaison, but... It seem that it's not really comparable.
Thanks for your answers anyway !
Hi @n3ro.
You have written the correct command. You dont need the incomingMessage if the sensor doesnt expect that.
Yes, atleast the nodes in strategic locations. I have some node in the outskirt of my network which is USB powered and not a repeater... no point how i see it.
Dont use delay() or block code in any other way if you are using it as a repeater.
Hi @Rolo6442u - welcome!
st=fail means the radiotraffic between the node and gateway fails in some way.
Sometimes it can reach the gw, but some more skilled in the code need to present you with the details.
If you use a nrf radio and you dont use a 4.7uF cap on VCC-GND thats a good advice.
Hi!
You should try to make a node with the TCRT5000 IR Barrier Line Track sensor
It emits an infrared light and detects the reflection.
Its used in the water meter: http://www.mysensors.org/build/pulse_water

Looks good..
I found some code here for it:
http://forum.arduino.cc/index.php?topic=212749.15
I've not looked any further as to what people may have done with respect to counting people etc..but im sure there is some out there!
Not too cheap though.. $80AUD here!
Thanks 4 all the input!
I thought about measuring only, but powering the node is a possibility i nearly ignores. Stupid me ☺
This intercom has a regulated 18v DC power source. So i should be fine.
I don't think Arduino has a standard sleep function. Which function do you mean?
The MySensors sleep function does several things, including powering down the radio (if a radion is used). It is quite power efficient.
