implementing multiple sensors
-
@waynehead99 you most likely need 1.4 Lib for the new sleep constructor. I have not used sleep on 1.3 so I do not remember what arguments you had available there.
I have also extended sleep with an additional constructor which @hek has pulled into the release branch of 1.4 that permits you to use two external interrupts with independent triggers for sleep in addition to a timeout. Great for nodes with multiple sensors that still run on battery. -
Im trying your code and its almost what im looking for.
I have two questions about it:
1 : Is it possible that the battery info has is own child id?
2 : Why dont you implement a light sensor like an LDR?I think that including LDR/light then you have the ideal multisensor ; light + temp/hum + motion + batt monitoring !
But for now im playing with your code and try to implement light. -
Here is a version I'm currently using that makes use of interrupts so might be more suitable for a battery driven DHT/Motion multi sensor. It also includes the battery monitoring. Any feedback or improvements would be appreciated.
#include <SPI.h> #include <MySensor.h> #include <DHT.h> #define CHILD_ID_HUM 0 #define CHILD_ID_TEMP 1 #define CHILD_ID_MOTION 2 // Id of the sensor child #define HUMIDITY_SENSOR_DIGITAL_PIN 4 #define DIGITAL_INPUT_SENSOR 3 // The digital input you attached your motion sensor.

The battery percentage is associated with the parent Arduino Node in the vera UI.
I have some LDRs ordered from Ebay so that is the next step. I had previously used the BH1750 I2C sensor in a multi sensor with the 1.3 lib but I want to debug on its own as it seemed to be giving unexpected readings.@codenea The instructions are pretty much from the main page although if I get a chance I try to draw it up and post some pics. My setup not very pretty yet with perf board and jumper wires. A dedicated PCB would be nice.

Hello,
Here is my combo to make a Home Monitoring solution:
https://github.com/empierre/arduino/blob/master/MQv01dgi_1_4.inoIt includes (currently on a Mega):
- Barometer : BMP085
- Temperature + Humidity DHT11
- Particle sensor
- Gas sensors MQ2 MQ6 MQ131 MQ135 TGS2600 2SH12
To be added when stabilized:
- Sound level in DB
Could be added:
- Light sensor
- Vibration sensor
- PIR

Hi guys,
this is a one node with publishing DS temperatures and listening for relay commands I finished and tested yesterday>
https://github.com/pgo-sk/mysensors/blob/master/arduino/DS_and_Relay.ino
feel free to comment/use/publish...I combined the Dalas and Relay examples together - you have to deactivate the sleep for the relays to listen 100% of time.
MQTT identification on openHAB:
MyMQTT/20/0/V_TEMP - DS sensor(s)
MyMQTT/20/1/V_LIGHT - relay 1
MyMQTT/20/2/V_LIGHT - relay 2If somebody is interested I can post the maps/items files for openHAB
Regards,
Pego
PS I am working on an home automation system with solar hot air panels control/solar hot water panels and all the common stuff like lights/temperatures/weather etc.. More here: https://github.com/pgo-sk/mysensors/wiki/Home-automation-using-mysensors-and-openHAB -
I'm also following along interested in the Temp, Humidity, and motion sensor.

@aquapro said:
I could not decide yet on a platform. OpenHAB should be my next test.
It runs quit stable on my old WinXP64Pro Quadcore w/many virtual machines on it.
Have still some problems with the syntax of the openHAB settings, but else nice controller ;) -
@Dany - yes. Checkout http://www.mysensors.org/build/dimmer
-
@blacey I tried this already. This is a simple dimmer node, not RGB. It's work fine.
But I would like to use a RGB colorpicker in openhab.@Dany said:
I would like to use with a RGB colorpicker in openhab.
I would do that soon too. Would you like to have a node only as rgbw dimmer or maybe with a lux sensor as I like to do to also adjust for constant light/lux in the room?
In my menu you can see the setpoint for lux under the light sensor.
