openHAB 2.0 binding

TimO

@gonzalonal : I found a solution for V_STOP! It will be available soon.

But more important: @andreacioni is doing some great work improving the stability and performance of the binding!!

I just wanted to let you know, that the binding is currently under heavy development. :+1:

@TimO
Great news TimO. Really nice to hear that.
Regarding STOP functionality for the binding, I have read somewhere that the supported commands by OpenHAB, for RollerShutter items, are Up, Down and StopMove. Have yoy tried something like this?

Regards
Gonzalo.

Yeah, my problem till yesterday was, that I was not able to cast the given state to StopMoveType in case of Stop, while casting the state to UpDownType for Up and Down was no problem. :-)

I changed the way how the binding handles this type of message and it works now.

Can we clone the latest source code from this binding? I think that your github repository is outdated and I want to work this weekend with it, 'cause I would like to integrate the mysensors 2.0-beta "smartSleep" feature with your binding in my home sensors setup (ESP8266 Ethernet GW).

Also, if there are any ISSUE y your TODO list in which I can help you, please tell me.

Hi Sebastián, what repository have you checked? Currently the development is not on the old https://github.com/wishmoooop/openhab2/tree/master/addons/binding/org.openhab.binding.mysensors but was moved here: https://github.com/tobof/openhab2-addons/tree/MySensors/addons/binding/org.openhab.binding.mysensors

Hope this help :)

Thanks @andreacioni
I was working on the old repo! :)

I've updated the first posting in this thread. You'll find the current repo there (also). ;-)

I've added a Wiki to the repo and made a brief description of the installation and configuration process.

https://github.com/tobof/openhab2-addons/wiki

The current binding (jar) is also in the repo now. You'll find the link in the wiki under "Installation".

Modifications in the current version:

RollerShutter now supports STOP
Performance of the binding improved. Big thanks to @andreacioni !!
Stability improved. Also big thanks to @andreacioni
Error handling on connection loss improved
The baud rate of the serial gateway is now adjustable. (@andreacioni again!)
some code cleanup: removed not needed debug output etc.

Please let me know if you found the time to test the binding and what the results are. :-)

Thank you @TimO !
This weekend I started migrating from my OH1.8 + mqtt GW setup to OH 2 beta + your binding. At the moment all is working fine, I spent some time learning about OH2 / Eclipse smartHome and watching your code, because I want to implement the smartSleep feature (https://github.com/mysensors/Arduino/pull/271) in the mysensors binding.

My idea is: when the handler don't receive an ACK from a message, it store the message for a while, waiting a heartbeat from a node, and, if the binding has some message stored for this node, then send it again. I don't know if this is correct, or if you thinks there is a better solution.

That sounds like a good plan. The binding already uses a queue where messages that should be send are buffered and you are able to specify how long a message is hold in the queue (when it is time to send again).

I've already implemented a mechanism to request for an ACK message. This mechanism sends a message to the node, but holds this message in the queue and increments the number of retries (currently 4 retries, with different/longer delays). If the node responds with an ACK or the number of retries exceeds 4 the message is removed from queue. So you could indicate, with a configuration setting, that the node is an smartSleep node and thus only send the message once and if no ACK is received store the message for 10 minutes (for example) in the queue.

Here is the implementation: https://github.com/tobof/openhab2-addons/blob/MySensors/addons/binding/org.openhab.binding.mysensors/src/main/java/org/openhab/binding/mysensors/protocol/MySensorsWriter.java

BUT: The reader and the writer are working in different threads (asynchronus), so we have to sync the threads (the queue), if we receive an ACK and remove a message from the queue. I'm still struggling with that and that is the reason why the request for ACK should not be used at the moment and this will be a problem for smartSleep too.

According to the ACK feature: if the binding don't receive an ACK after 4 timeouts it will revert the status of the thing to the last value. So if you for example try to switch on your light and the message is not acknowledged, the binding will revert the switch state to off. I've removed the code for this, because of the issue above, but will add it again in the future.

Hello everyone

I'm testing MySensor Ethernet gateway with a relay code on it. My understanding that Gateway stores the current state of the relay (or GPIO port) in it's EPROM. Can the binding periodically check the state of the port or should I rely on OH persistence functionality? Please advise what is the right way to keep the states synced between the Gateway and OH.

Thanks
Andrew

Hi Andrew!

Good question. Polling is currently not supported by the binding itself, but what you could do is: send a message from the node to the gateway, when the node restarts (the moment after you read the EEPROM and set the output of the pin).

Greetings

@TimO , thanks for the idea.
So I can probably take some code used for reporting button presses in the examples and use it in the 'message'.

Thanks again
Andrew

Hi Tim0.

I have read all your instructions in the GitHub Repo.
Is there any special reason why you suggest to add things in manual, text way, rather than with the PaperUI?

I have done it with the PaperUI and manually restarting my nodes and everything works just fine.

Let me know what you think.
Regards

I wondered that but I'm quite new to OpenHab so did some looking in to how various things work..

PaperUi uses something called MapDB which is basically a non-human readable configuration file. If you add "things" via PaperUi as far as I can tell you've still got to link the thing to an item for OpenHab to work with as far as I can tell..

I opted to do everything manually like in the wiki, seems much simpler

I get the impression PaperUi is still very new and not for production yet... its not compatible with sitemaps as they are waiting to implement a version of sitemaps in PaperUI or something.. I think it all boils down to the fact they want to keep V2 100% compatible with V1 configs and bindings etc so all the new stuff in V2 isn't quite ready yet...

Anyway might have totally got the wrong impression but that's what I see as a new OpenHab user going straight to v2.

On another note the work your doing TimO is awesome!

TimO

@gonzalonal

I totally agree with @Qu3Uk ! :-)
Both ways work and currently I like the configuration with the .items file more.

In an early version of the PaperUI it was possible to change the status of items (switch lights on and off). Maybe something like this will return or habmin2 will fill the gap.

I need support for HVAC device, how much work is there to be done to get that included.

I have made a thermostat controller for my Wirsbo floor project can be found under myprojects wirsbo uponor thermostat replacement

TimO

@Denke What is it exactly what you need? Which types?
How is the setpoint set (request/send)?

Greetings
Tim

@TimO
Hi Tim
I use gw.present(0, S_HVAC); to present the sensor to the controller

I use the following messages to send information
MyMessage msgTemp(0,V_TEMP); //temperature of thermostat
MyMessage msgFlowState(0,V_HVAC_FLOW_STATE); //tells if the thermostat is active HeatOn or off
MyMessage msgSetpointHeat(0,V_HVAC_SETPOINT_HEAT); //used for setting wanted temperature
MyMessage msgKnobTemp(0,V_VAR1); //gives the wanted manual temperature set on the thermostat knob (used for fallback when home automation dont work
MyMessage msgRunningMode(0,V_VAR2); //running mode internal or external internal = knob value used, external set by home automation
MyMessage msgHystLow(0,V_VAR3); //used if hysteresis needs to be changed (low value)
MyMessage msgHystHigh(0,V_VAR4); //used if hysteresis needs to be changed (high value)
MyMessage msgUpdateTime(0,V_VAR5); //used to set system sampling/update time

All of the above values are sent out from the thermostat at update sampling time interval.

V_HVAC_SETPOINT_HEAT(msgSetpointHeat), V_VAR3(msgHystLow), V_VAR4(msgHystHigh), V_VAR5(msgUpdateTime) can be set from the controller to update the thermostat parameters

Hi TimO.

I am trying to do a gw.request from one of my nodes that requires the value of a numeric item from OpenHAB.

Have you tested this? I am unable to make it work.

I have created a rule:

rule "Heart Rate request"
when
	Item Heart_Rate received command
then
if (receivedCommand == "REQUEST")
{
	logInfo( "Heart Rate", "Heart rate request")
	sendCommand(Heart_Rate, Heart_Rate.state);
}
end

Please, let me know if I am doing it the wrong way.
Regards.

I seem to be having some issues with the dimmer function and I'm not entirely sure if its OpenHab, the binding or MySensors... but I seem to be able to crash the gateway once OpenHab boots up... The node is basically running DimmerLED stretch

I notice the ItemState is null and that sort of makes sense why if OpenHab has been restarted but surely if it is null it shouldn't cause the gateway to go offline? Also it doesn't reconnect which is probably more of an issue.
