If you use Set to send your temp/hum you can define how many decimals you want:

MyMessage& set(float value, uint8_t decimals);

For example:

gw.send(msgTemp.set(temperature, 1));

will send you the value with 1 decimal.

@marceloaqno

I have it working only need to play with the debounce value

@ahmedadelhosni that really sucks

mfalkvidd means:

gw.wait(dht.getMinimumSamplingPeriod());

In the first sketch change

gw.begin (msg, NODE_ID) ;

to

gw.begin (NULL, NODE_ID) ;

Another way is to track the amount of people that enters the room. This can be done with a double IR beam horizontally placed next to each-other (IR-A and IR-B). Now when a person walks into the room, you know that IR-A triggers before IR-B, and you increment the room-occupants-counter with 1. If the person leaves the room, IR-B will trigger before IR-A and you decrease the counter.

The IR barrier can be installed inside the door casing.

Using this technique you don't need a PIR sensor, unless the room has a window and you want to detect movement without someone passed the IR beams (a burglar maybe?)

Combine the IR beams with a lightsensor and you can also define that the light should go on only below a certain light level.

My 2 cents...

Maybe this will help: http://jmsarduino.blogspot.be/2009/10/4-way-button-click-double-click-hold.html

Is your controller setup to hand out ID's to the sensor nodes?
What if you set a fixed ID?

I'm developing a controller and I reset my sensor nodes all the time and the ethernet gateway keeps working as expected.
My advice: do not power your nRF from the arduino 3.3V pin, instead, take power from the 5V pin and step that down to 3.3V using a voltage regulator. (like LM1777 including caps)

Just took the time to shoot a pic of my Step-Up consumption, including a Voltage regulator MCP1702-3.3

As you can see, it's consuming 54uA with nothing connected.

Step-Up module: link

The capacitors are really important, one on the input of the step-up module, the other on the output of the MCP1702-3.3, both are 22uF. Without them, consumption is 2.20mA

please indent your code with 4 spaces to keep it readable.
And in the arduino gui press CTRL-T to tabify your code correctly

The high-performance Atmel ATmega328PB is an 8-bit AVR RISC-based microcontroller (MCU) with picoPower technology. It combines 32kB ISP Flash memory with read-while-write capabilities, 1kB EEPROM, 2kB SRAM, 27 general purpose I/O lines, 32 general purpose working registers, five flexible timer/counters with compare modes, internal and external interrupts, two USARTs with wake-up on start of transmission, two byte-oriented 2-wire serial interfaces, two SPI serial ports, 8-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator, a unique serial number and six software selectable power saving modes. The device operates between 1.8-5.5 volts.

The ATmega328PB is the first 8-bit AVR MCU to feature the QTouch Peripheral Touch Controller (PTC), which acquires signals in order to detect touch on capacitive sensors, and supports both self- and mutual-capacitance sensors. The PTC is supported by the QTouch Composer development tool (QTouch Library project builder and QTouch Analyzer). It provides a faster and less complex capacitive touch implementation in any application.

The ATmega328PB supports 24 buttons in self-capacitance mode, or up to 144 buttons in mutual-capacitance mode. Mixing and matching mutual-and self-capacitance sensors is possible, and only one pin is required per electrode – no external components are required, delivering savings on the BOM cost compared to competing solutions.
By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.

Nice feature for MySensors is that it has 2 SPI interfaces, so nice for the ethernet gateway and also has a Unique ID

There are only 2 interrupts available, thats why you are not seeing the pulses from the 3th
