@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.

Hello, so Im planning to build an small Hum/Temp sensor, but it cant be powerd by usb it has to be done with Batteries, I will use an small Arduino Pro Mini with a NrF24 and a DHT11 Sensor, my question is do I need to modify the "My sensors" code for the Batteries to last some time?! I will be using a 3 AA batteries........... Thank you so much!!!

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

Hello Im kind of new at Arduino, sorry if someone has ask this befor but I keep getting the Msg

C:\Users\RV\Documents\Arduino\Temperature.Humidty\Temperature.Humidty.ino: In function 'void loop()':

Im using the code from my sensors page.

And the Libraries too.

Tks.

Can you use the RP as gateway and also as controller?

Ok, yes its a DHT11 so maybe thats why. And the environment its a closed its my Babys room so maybe that why.

Tks.

Its normal to have like 5 hours without any changes in the reading of my temp and humidity sensors?!

YES!!!!! That was the problem!!! Thanks already working I already added some sensors and its working Beautiful!!!!! Hope you keep developing and keep the good work!!!!

Best regards

Thank you for your info.

But Im still getting that cannot connect to the server.

My IP its 192.168.6.220:8443 when I tried it seems not to exist.

I didn't change anything on the configuration file, so maybe thats something that Im doing wrong.

Sorry for the inconvenience but Im new, but want to learn!!

Best regards

Hello, sorry for the trouble but I´m new with Linux and Raspberry Pi, I have an Raspberry Pi 2 and when I try to star the server I get

/usr/bin/java
java version :1.8.0
Start issued for Mycontroller

Is this because of the oracle java?!?

Thank you.
