Some good tip that you guys have give me.
Most of them i already tried before. I have worked a lot with electronics so I know how to connect the parts i give them the correct power.
The sensors is working and i can see the transmissions from the nodes to the gateway thru serial monitor. The problem is that both Vera and Domotics are losing connection with gateway. Tried both Serial and Ethernet.
I read somewhere that Vera dosen´t work so well with serial gateway so they recommend Ethernet. The last hope is that the W5100 will solve my problem.

Thanks guys.

@Maurice-Krijtenberg
I'm using an existing board so everything is already connected. I have the sensor on pin 3. Sadly it was not that easy

Thanks for your reply.
I have tried with several hardware's.
The only thing i haven´t tried is W5100 because i only have some ENC28J60 modules.
The problem with API 2.0 is that not all of the projects that i have build are rebuild for 2.0. Example the Irrigation Controller that is found here in the forum from "hek".
I will give it a try as you describe and hope it will work.
PS. I have ordered a W5100 to try with but i will take some weeks before delivery.

Thanks again.

@pettib It´s working now.
I got wrong version of Mysensors API
Now i use 2.01
The time will tell if it get stable.

Hi
I also have problem to get the NRF24L01+ chip to work with the RPi3.

I find that the masterbranch don't recognize the board as RPi3 and sets SoC and Type as unknown.
But if i take development branch it´s detecting RPi3 and seems to work correct.

This is result from development Branch configure:
[SECTION] Detecting target machine.
[OK] machine detected: SoC=BCM2837, Type=rpi3, CPU=armv7l.
[SECTION] Detecting SPI driver.
[OK] SPI driver detected:BCM.
[SECTION] Detecting init system.
[OK] init system detected: systemd.
[SECTION] Saving configuration.
[SECTION] Cleaning previous builds.
[OK] Finished.

This is result from Master Branch configure:
[SECTION] Detecting target machine.
[OK] machine detected: SoC=unknown, Type=unknown, CPU=armv7l.
[SECTION] Checking GPIO Sysfs.
[OK] /sys/class/gpio/export found
[SECTION] Detecting SPI driver.
[OK] SPI driver detected:SPIDEV.
[SECTION] Detecting init system.
[OK] init system detected: systemd.
[SECTION] Saving configuration.

This is the result from cat /proc/cpuinfo:

@gohan exactly what I meant.

Do anyone has a working solution to connect this project to a main valve who has to open when running the zones ?

Hi everyone.
I´m trying to build a new homeController with the following parts / software.

Raspberry Pi 3
Home Assistant
MySensors
Tellstick
Mosquitto MQTT Broker

I got everything working beside the MySensors. I´m trying to connect the NRF 24L01+ chip directly to the RPI with help from https://www.mysensors.org/build/raspberry.

I want to use MQTT between MySensors and HomeAssistant
The MQTT broker is working when i´m testing it.
The Mosquitto is configurated with username and Password in the config of Mosquitto.

The config i´m using when Make Mysensors is the following:
./configure --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mygateway1 --my-transport=nrf24 --my-rf24-irq-pin=15

I also changed in the file /examples_linux/mysgw.cpp
#define MY_MQTT_USER "My User"
#define MY_MQTT_PASSWORD "My Password"

When i´m running the command: sudo systemctl status mysgw I got following result.

● mysgw.service - MySensors Gateway daemon

Please help figure this out.

@dbemowsk I run that way now. Same time for both with debug and without. It works well with debug activated but not with debug inactive. Same time on both.

@dbemowsk
@dbemowsk
The reason that I use different sleep time is that this is a battery powered unit, and when debug I don't want to whait for 15 minutes to see the readings. I don't understand why the long sleep will stop me from get the readings ? It's the sleep between readings I change with this function.

Hi again.

Now i made a sketch that almost work.
If i run it with debug enabled it works fine but when i run it with debug disabled it dosen´t work.
Please help me to find the problem.

@dbemowsk can you please share your sketch ?
And witch library for dht22 are you using ?
