implementing multiple sensors

[integlikewhoa]

I'm also following along interested in the Temp, Humidity, and motion sensor.

@integlikewhoa check this :

[pgo]

https://github.com/pgo-sk/mysensors/blob/master/arduino/DS_Light_Relay

• DS18B20 (up to 16 like in original temp sketch)
• TEMT6000 reporting LUX light values
• 2x Relays
  running and tested
  Sensor <-> MQTT gateway <-> openHAB/PC

When interested can post the openHAB items/sitemap(s) settings

Screenshots - over teamviewer, sorry for the quality.

Here the TEMT6000 output - in a quite dark room and changing weather today>

Here the temperature and relays:

Has anyone made ​​RGB LED strip node? I am looking for a working example program ...

[blacey]

@Dany - yes. Checkout http://www.mysensors.org/build/dimmer

[korttoma]

Or here is an example I'm using:

Hi, I'm interested. :-)
Or is this the latest version ?

Yes :), for the sketches mentioned earlier.
<Comment to myself: Have to switch to some versioning as now I am already deeper in the project including cameras, weather forcasts etc.>

I could not decide yet on a platform. OpenHAB should be my next test.

My Current openHAB items/sitemap. 1 multisensor with Temp/Lux/Humidity sensor, 1 ethernet/MQTT gateway.

Also weather forcast from yr.no and Samsung TV remote controls (Mute working, rest not so much)

• openHAB v 1.5.1
• Addons :

HABmin conf with graphs:
charts.xml -put in openhab/etc/habmin

In habmin.cfg specify the IP of your MQTT arduino and port>

mqtt:mysensor.async=true

Here some screenshots:





These (Direct channel/Channel/Volume) does not work yet... Mute is OK and Volume displays only the current TV volume.

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]

@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.

[pgo]

@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.

[Dany]

@pgo The RGB Colorpicker works already in openhab.
I have some problem in arduino side...i tried update the sample DimmerActuator code, but didn't work. I tried korttoma's code, but it didn't works for me, too.

(e.g. message.header.childId -didn't work)

Can you post the HW connections you use on arduino and the items/sitemap of the dimmer in openHAB? I can then check on my install.

I combined Humidity and Lux code. Serial monitor works ok (see below) but for some reason when I try to add node to Vera I get only node, temp and lux (no humidity). I guess something is wrong in combined sketch?

@niccodemi Check:

gw.send(msgHum.set(humidity, 1));
gw.send(msg.set(lux)); I miss here ",1"

[niccodemi]

@pgo thanks, all sensors show up now.

[niccodemi]

One more combined sketch - UV / Light Lux. Everything seems to work ok except only 2 items show up in vera: node and lux sensor. UV sensor is missing.

There is a perfectly good explanation why UV sensor isn't showing up. MySensors does not distribute any device files for it. It might work with the rfx-plugin-device:
