Minimum sketch requirement for OpenHAB discovery to work

[Pavel Hrudka]

Hi.
I upgraded my gateway to latest stable version. (great tutorial btw)

I had some really old nodes which I decommissioned and want to build new ones.

Since there were some major changes in mysensors since ver 1.4 upon which they were built,
I was thinking that I would like OpenHAB to autodetect new nodes and would like to know what is the minimum that has to be done in sketch to be autodetected by OpenHAB.

Right now Iam testing actuator sktech with staticaly set address.
here

When I delete this manually added node, I would like to be discovered by OpenHAB.
Or does it work only with new nodes (never registered to gateway?)

Or is there any other rule which I need to follow?

Thank you.
p.
p.s.:
Iam running on RPI2 wheezy latest apt-get update & upgrade,
GW is on RPI2 connected using SPI and built from latest stable git repo.
OpenHAB ver 2.4 from apt-get.
MySensors binding ver 2.4.0.
Communication is tested and I can see node on gateway (in debug logs)

You have to present a node and it will appear as a thing. The rest can be empty.

I'm talking about mysensors-binding over mqtt, which is what I'm using.

Thank you.
I did eprom reset and then uploaded another sketch from mysensors examples at arduino.

Where i start the node everything seems to be fine

But I still cant see it in OpenHab inbox or find it using autodiscovery.

When I add thing manually everything works as it should.

Are there some cashes which needs to be cleared?
Thank you.

try giving it a different node id

@pavel-hrudka I know this is quite an old post but I discovered tonight that when openHAB would not discover my node, I hit reset on the node and openHAB discovered the sensor when it restarted and contacted the GW. May help someone in the future!
