openHAB 2.0 binding

[Cliff Karlsson]

after installing openhab2 this way how do I keep it updated?

[bpair]

This is probably a better question for the openHAB2 google group but is there anyway to persist the data without having to create a items.xml? Or another way to put it, is there any way to persist data for a sensor that is detected and added?

[gregl]

For those interested in OpenHAB - they have a new forum here:
http://community.openhab.org/

I think/hope it will be easier to use that the google groups.

@gregl the link doesn't work, here is the correct one:

(only that annoying little s after http i think ;) )

Firstly great work on the binding... it makes openhab2 a bit more attractive.

Not entirely sure how to debug this further as I'm very new to openhab but after setting all my sensors up (even via discovery which is cool) after I restart the openhab2 service the MYS things never get initialized and stay in the UNINITIALIZED state.

Running on RP2 and start_debug.sh I see the incoming MYS messages but OH2 is not updating the thing, for example

2015-08-15 04:04:57 [DEBUG] [b.m.p.ip.MySensorsIpConnection:68 ] - 4;0;1;0;0;29.0
2015-08-15 04:05:08 [DEBUG] [b.m.p.ip.MySensorsIpConnection:68 ] - 1;0;1;0;0;30.0

However if I go in to the thing via the paperui, edit/save it. The thing is then initialized and I can see in the console OH2 updating the thing when a message is received.

2015-08-15 04:08:53 [DEBUG] [b.m.p.ip.MySensorsIpConnection:68 ] - 1;0;1;0;0;30.0
2015-08-15 04:08:53 [INFO ] [runtime.busevents :27 ] - mysensors_temperature_08797005_Temperature_1_0_temp state updated to 30.0

I deleted the userdata directory before updating to the latest version 3 days ago.

No idea if this is a OH2 issue or a binding issue though.

@Qu3Uk: Thank you for the report. I am able to reproduce this. I suppose it is an error in my binding because some parts are started correctly. I will look into it.

[Qu3Uk]

@TimO Good to know its not just me, may still be O2 it is alpha after all.

Now to figure out these rules..

Hi @TimO, any chance you add support to MySensors MQTT to your great work in progress ?

[Cliff Karlsson]

How do I add this button from the paper UI ? I can´t understand what to enter in the child id, node id fields.

@Cliff-Karlsson : Start the discovery process in the paper ui and after that restart your sensor. The sensor will represent itself while starting up and should appear in the paper ui.

[TimO]

@fets: I'm not very familiar with MQTT but that should already work with the 1.X binding, or not?

[fets]

@TimO yes I think it works with manual bindins (several discussions mention it) but I meant using paper ui as you do here :)

[Cliff Karlsson]

Well if I add a door sensor and just enter some random node id/child Id it shows up as online. I never managed to add any sensor automatically even if I start the search process and resetting any sensors.

But the problem is that I can't get any reaction from the switch. I have tried connecting a button to pin 3 and also tried just connecting a cable from pin 3 to gnd. But no reaction whatever I do.

[TimO]

@Qu3Uk : Fixed the error. The sensors were initialized before the bridge was up.

@Cliff-Karlsson: The status of a thing in OH is not reliable and I'm yet not sure how to make it reliable because the connection between sensor and gateway is stateless, so a sensor maybe is online even if it only transmits one time per day.

In your case: what is the output of the "start_debug.sh"? Are there messages from the MySensors Gateway logged?

Nice work!

Did anyone try the binding with FakeMySensors?

[ZoTyA]

after OH2 restart I got "UNINITIALIZED - HANDLER_INITIALIZING_ERROR" for all already existing sensors. If I add a new sensors it works until OH2 restart

@ZoTyA said:

This should be fixed but I don't think @Tim0 has released the fix yet? Might be wrong.

[TimO]

I'm pretty sure this time it is a bug in OH2, because my code works sometimes. :-)
I've found a workaround and got 10/10 clean starts of OH2 and reinitializations of the configured things.

Please let me know, if the error occures again!

Thanks for testing!!

How do I keep openhab2 updated after installing?
