@mfalkvidd YES!!!! That was the problem!!!! Thank you so much!!!!

@mfalkvidd YEEEESSS definitely that was the problem!!!! Well .......... "Living and learning" I blew two Nrf24 antenas!!!

@mfalkvidd So I just got home and power another NRF24 with the 3.5 volt coming from the USB-STC-ISP and its working, I need to figure out how to power the Arduino with only 3.5v from a 6v power source (4 AA batteries). Can you guys help me with some ideas to do it?! I thought in doing it with 2 resistors but Im not sure, I dont want to burn another NRF24

@mfalkvidd YEEEESSS definitely that was the problem!!!! Well .......... "Living and learning" I blew two Nrf24 antenas!!!

@mfalkvidd Nope I powered the whole system, but I think that without any regulator yes, the NRF24 recived 5.5v, I think I blew it !!!

@gohan So I builded another Hum/Temp node, I did it on a protoboard and uploaded the sketch, It worked fine, then I took out the LED and the Regulator from the Promini and power it with 4AA batteries (5.5 V total) STOPED working again!!!! Could I have burn it with that Voltage!??? Or burn the NRF24?!?! This is getting really frustrating, maybe if I use a Nano instead of Promini.................

@gohan But if I use the 2.2 I have to update the other nodes and the gateway?? Im worried to mess the ones that are working.

@gohan Could that be the problem?!?! I will try it when I get home, but on my first sensor im pretty sure I used the IRQ. Thank you for your time and help.

Tks for your answer, I will double check the wiring (Again), on the POST that you sent me the IRQ on he NRF24 its not wired to anything. Mine its wired to Pin 2 on the Pro Mini.

Ok, so Im using Domoticz with an serial getway, Im using and Arduino Nano for the getway, I builded 1 Hum/Temp sensor with an arduino uno and a protoboard, and its working fine, the problem starts with another building of the same sensor but with a pro mini, I weld evreything and double check the connections order and also the transmition between the cables that I weld, evreything looks ok on the multimeter, but the node simply does not connect I keep getting " 0 MCO:BGN:INIT NODE,CP=RNNNA--,VER=2.1.1
3 TSM:INIT
4 TSF:WUR:MS=0
11 !TSM:INIT:TSP FAIL
12 TSM:FAIL:CNT=1
14 TSM:FAIL:PDT
10016 TSM:FAIL:RE-INIT
10018 TSM:INIT
10024 !TSM:INIT:TSP FAIL
10028 TSM:FAIL:CNT=2
10029 TSM:FAIL:PDT "

I was thinking that there was something wrong with the building but then I made one more of the same sensor but with a Arduino Mega and a protoboard, I keep getting the same message!!!!! And the first node still working so there is nothing wrong with the gateway I think!!!! What else could it be?!?! I also teseted the DHT sensor and works fine in both the Promini and the Mega, and I tested two different NEF24 antennas they didnt work.

Please help me out!!!!

@gohan Because I just cant find other sensors here in Mexico, I will buy some in Aliexpress, but for know I have to work with DHT sensors, I will get rid of the regulators on the Arduino and also the LED, do you think than a LiFePo4 has the juice to power the arduino, sensor and the NRF24 antenna?!? I will modify the code so it gets to sleep for almost all day, I will put to mesure only like 1 time each hour or something like that.......

Thank you for your help!!! Here in Mexico I just cant find those sensors, so I will order on Aliexpress, but for know I have to use DHT sensors, I will get rid of regulators and LEDs to save some power. Do you use PRO MINI on your nodes?! I have no idea where to weld the power input from the batteries to the pro mini, If I have like 4 AA Batteries in series can I put them directly to the Arduino board?!?! Sorry for all the questions but Im pretty new at this!!! I saw you 3D design, Its is for UNO?! Best regards.
