Hi Martin,

@martinhjelmare
I've been trying the last couple of days to get it working, but to no avail...

I stell get errors like

ValueError: need more than 1 value to unpack

The number can change though.
I've tried your suggestions, updated and rebooted the pi but still no luck.
Uninstalled and reinstalled home assistant but that also didn't help.

Any other things I could try?

I just received my order from Dirtypcbs. The protopack I ordered had 11 boards, so that's nice.
They took 10 days to arrive in Belgium.
From first glance, it looks like they's work, but I'll have to test it this weekend to be sure.
Here's a picture.

Great, thanks.

The sketch now works as it should.
Below is the finished sketch.
I also added a counter so that after 10 consecutive interrupts from the motion sensor, the temp and hum get read and transmited. (motion-on generates an interrupt and motion-off generates an interrupt, so it's actually 5 motion triggers)
Otherwise if there is a lot of movement during a certain timeframe (mornings), hum and temp won't be measured.

Later I will edit the sketch to have all transmits together to save more battery power.

Here's the sketch:

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

About D2: you mean I shouldn't solder the IRQ of the radio to the board?
I will try that next time.

I've been testing the PIR with a nano and the 3.3V it supplies and that works fine.
If I take VCC or ground (or both) from the board with booster, the PIR starts acting up.
I guess I'll have to try some more if I want to get to the bottom of things.

@sundberg84
Hey, I've been having a bit of trouble lately.
I've been trying to setup a node with your board which supports a PIR and a temp sensor (ds18b20).
Since there is a spot for a resistor on D3 on your board, I attached the temp sensor to that pin.
The PIR needs a pin that supports interrupts, so I connected that to D2.
Here is where the confusion starts.
If I read this page correctly, D2 is already in use for the radio.
I only checked it after I soldered everything together and found out my PIR doesn't work (it always sends a 1-signal).

Any thoughts on this?
Is D2 really free for use on the board?

Thanks!

@sundberg84 said:

If you use the FTDI connector, make sure its the 3.3v and connect it to Gnd/Pwr on the PCB and not Arduino FDTI connector.
You could just exclude those pins and connect a battery directly and use that as power and the FDTI as programmer/serial debug only

Bat or Reg is nessecary!
See this picture for battery use: https://www.openhardware.io/view/4/EasyNewbie-PCB-for-MySensors
https://www.openhardware.io/uploads/568ed84b60aa3f8965fbf095/image/3.jpg
All components in the image is needed (except battery measurment).
If you dont want to use booster you need to bypass that one with a wire/jumper (or set the jumper on REG instead of BAT but that kills the logic).

The battery doesnt "need" the 0,1uF but see here:https://www.mysensors.org/build/battery
"The tap point could be bypassed with a 0.1 uF capacitor to keep the noise level low, at this otherwise high impedance point. "

After reinstalling OpenHAB, the binding works fine, thank you!
Just a question, don't know if you can help.

I mapped my serial gateway to /dev/MSgw because ttyUSBx tends to change when unplugging / replugging multiple USB devices into the computer (raspberry pi in my case).
I've also got a 433MHz gateway attached and when debugging have to unplug it sometimes.
When trying to start OpenHAB with /dev/MSgw as gateway address I get this:

2016-02-14 10:58:33.418 [DEBUG] [.b.m.internal.MySensorsBinding] - activate
RXTX Warning:  Removing stale lock file. /var/lock/LCK..ttyUSB1
2016-02-14 10:58:34.048 [ERROR] [.o.b.m.internal.gateway.Serial] - Unable to find Serial port '/dev/MSgw'

Do you know how/if I can still you my own custom paths to the gateway?
Now I changed it to ttyUSB1, but that port might change after rebooting.

@bkl
Thanks for your response.
After adding the line of code to the logback, my debug output remains the same.
No message that new items have been added based on the configuration, nor parse-errors.

It's just the same as before: the messages are received, but not interpreted correctly, just the raw data like below:
2016-02-13 15:05:55.551 [INFO ] [.b.m.internal.MySensorsBinding] - Unknown: MySensors message: node-id=20, child-sensor-id=0, message-type=set, ack=false, sub-type=V_HUM, payload=48.0

I will start over again from scratch tomorrow, reinstall openhab and your binding to see if it helped.

BastienVH

Hi,

I've tried out you binding on OpenHAB 1.8.1.
It appears OpenHAB can connect to my serial gateway and receives the messages from my node, but doesn't know what to do with it.

This is en excerpt of my log:

All the sensors get declared and recognized as their type, but the messages are not being interpreted correctly.

This is my .items-file:

Number Humidity "Livingsensor [%s %%Rh]" <water> (GF_Living) {mysensors="20;0;V_HUM"}
Number Temperature "Livingsensor [%s °C]" <temperature> (GF_Living) {mysensors="20;1;V_TEMP"}
Switch Motion "Livingsensor [%s]" <motion> (GF_Living) {mysensors="20;2;V_TRIPPED"}

And the sitemap (which of course doesn't update anything yet):

sitemap default label="Main Menu"
{
	Frame label="Systeem"{
	Group item=System	label="Systeeminfo"	icon="computer" {
				Text	item=uptime	icon="computer"
				Text	item=Raspi_CPU	icon="computer"
				Switch	item=wakingup
	}
	}
	Frame label="MySensors" {
	Switch item=Motion
	Text item=Humidity
	Text item=Temperature
}
}

It's been a while since I used OpenHAB and went looking for something more lightweight that had better integration for MySensors, but with your binding, I could revert to include everything I've built for OpenHAB in the past.

Thanks for your initial work and I hope you can help me out.

@sundberg84
When I get the caps, I'll place them on the board.
I did notice alot of noise when I was reading battery state on a breadboard in an earlier build, so I will get that sorted.
Only problem is I can't find them locally, so have to get them from China.
Will take a while...

@BastienVH
Replying to myself to follow up on my assembly-issues.
I have been able to get the board to work.
I don't have my 0.1µF caps yet, so I just put a little blob of solder in the holes so the current could run through.
Now I've got myself 2 working board. I just have to find a good way to attach my PIR, dallas temp, ... to them.

Thanks for the work and help!

@mwild95
Could you share your sketch?
I'm planning to mysensor-ize my 433 wall plugs and it might be a good starting point
