I am not familiar with this board. look good. But mine design have few leverages:
- You can stack another shield on top.
- Have hardware Watch Dog Timer in case of your R-PI freeze.
I send command from remote control arduino read this command (i can see this in serial monitor) but this commands are not sending to gateway, my radio is working the sensor connect to gateway and controller. I use example Sketch given up in this page without changing anything.
Any idea whats wrong in my setup?
I need arduino code to send RAW sensor value, when sensor change his value to send this value to controller. The type of signals have to be V_LEVEL. Normally i will use this with analog sensors.
If somebody have this kind of code please share with us.
Is exist some way to calibrate DHT sensors? today i make a experiment assemble 5 nodes with 5 DHT11 sensors put all nodes on one table and leave them for some hours, and the result is the every sensor give different values about temperature and humidity + - MAX 5 degree Celsius around the real temperature in the room. Hardware used Arduino Nano X 5pc., HDT11 X 5pc., the power supply is 12V 2,2A enough to power all of the arduinos.
I successful tested my gateway, the gateway receives commands from nodes, but something missing the OpenHAB not receive commands from the gateway i install mosquitto but missing a lot of information:
How to configure openhab to connect to the mosquitto ?
in openhab.cfg i put this
mqtt:mysensor.url=tcp://localhost:1883 mqtt:mysensor.clientId=MyMQTT and other option is commented
my binding is
What this "MyMQTT means is this related to some setting in mosquitto?
I try to make raspberry pi 3 to work like a mqtt gateway according to this tutorial, but something is wrong.
1.How to check condition on the gateway working,not working, what sending, what receiving?
2.how to st my openhab to work with this gateway, i type this before "sudo make install"
./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
and what port should set on my opehnab config?
