I have a problem:
When i use fade up or fade down , openhab don't receive a value. But i use the fade up and fade down from openhab to AC module , the light dimmer okie.
How can i fix it ?
Thanks

Can i use Arduino Uno to make scene controller? If okie, please teach me to do it? thanks

Just for completeness, my PCBs came in and I've had a chance to solder them up. The PCBs are really nice. iTead have done a great job. @Zeph, turns out that I didn't need to cut my PCBs because the friendly folk at iTead cut them for me.

Here's a photo of a few things soldered on:

Underneath the APM I have a 1M and 470K resistors for the battery voltage check. There's also a 4.7K resistor for the Dallas DS18B20 temp sensor. Finally there's a 4.7K resistor for the LDR divider circuit.

You can also see the 4x2 header for the radio, the LDR itself, and the 3.3v step-up converter.

Here's the (almost) finished package:

You can see all the exposed solder pads for my various sensor configurations (motion, humidity, baro pressure, door reed switch, distance and soil moisture).

The range on the nRF24 is fine. I put my gateway at one end of the apartment and it easily picked up my sensor at the other end of the apartment (about 10m away through two thick internal walls). So I'm not worried about the nRF24 being parallel to the GND plane.

I actually took off the 4.7uF cap. It's probably my PCB (don't think the auto-route did a great job of it) but it made the radio flaky. Works just fine without it.

Now to find a box to put it in...

Can you share your board to me,pls? Im newbie. Pls email to me quocanhcgd@gmail.com Thanks

I activated this line but no result. may be openhab work wrong? What the controller you use?
@jeylites said:

@quocanhcgd

You will need to activate this line pinMode(Relays[i].relayPin, OUTPUT);

It should work right after.

Thanks for sharing.
I have a problem with this scripts. My relay auto start then off every gateway check node. How can i fix it?
Thanks

My house have 4 floor, i have plan build one gateway for each floor. Each floor has 4-5 sensors (temp, hum, relay, light, door, RF light). Each sensors use NRF24 to connect with gateway. Gateway connect to RAS by ethernet.
My question:

Can i build 2 gateway mqtt connect to openhab?
if not, what my solution to solve ?
Thanks
