Gree Lomo eco - status works but no control

[cytrus77]

Hi,
I'm using Gree Lomo eco air conditioner.
I'm getting in log:

I'm getting: "bc":"000000000000000000000000000000"
is this can be a problem for binding to control AC ?

[pbogut]

Module is not working with newer OpenHAB version. Main issue is thing/thing-types.xml, I managed to get it work by adding proper thing type definition. Someone did pull request with that 2 years ago, so I think this project is dead. What version of the Openhab you have? If you not fancy compiling yourself I think I can send you working jar file.

[cytrus77]

I'm not familiar with this binding compilation, so if You can generate new jar for me I will really appreciate.
Do You now where to find some guidline how to compile binding ? maybe I will also try it on my own.

[pbogut]

Some instruction is here: https://www.openhab.org/docs/developer/bindings/ but it took me a while to figure it out.

This one should work: http://storage.pbogut.me/org.openhab.binding.greeair-2.5.2-SNAPSHOT.jar it should go to something like /usr/share/openhab2/addons.

[cytrus77]

@pbogut thanks for that, but no progress.
It looks like bindings gives zero reaction for item change.

Looks like AC was bound as expected but when I change any settings from item list there is no action triggered. No single log about any request from user.

I'm using items list and sitemap from README example.

My openhab version: openHAB 2.5.5 Release Build

Any idea what else I can try ?
Really appreciate Your help. Thanks

[pbogut]

I would have to install 2.5.5 and check, now I don't have open hab but I'm 99% sure that jar worked (could be different one though, can't check now). I've did a fresh compile, and then did git pull on openhab-addons and compiled once again. It produce two different files, you can try:
http://storage.pbogut.me/1/org.openhab.binding.greeair-2.5.2-SNAPSHOT.jar
http://storage.pbogut.me/2/org.openhab.binding.greeair-2.5.2-SNAPSHOT.jar

If still doesn't work I may test myself during weekend. Have no open hab now as my RPI sdcard died.

[pbogut]

@cytrus77 I was checking it some time ago and it was not working at all anymore (I'm sure it used to though...). I decided to rewrite it (as I had some issues with it even when it worked, and this repo seams to be dead). If you still interested here it is https://github.com/pbogut/openhab-ewpesmart-binding/releases/tag/v0.0.1

@pbogut Hi Pawel, thank you for your great efforts, i just saw your comment. There is another fork of the greeair binding, now called gree binding. It is available with OH 2.5.7 from official repo also, @markus7017 made it working again with OH 2.5+. You may want to sync with him, to avoid double work. As far as i see, the only real difference is that your binding can read the built-in sensor of the aircon unit. Does this function work, did you test it?

OpenHAB 2 Gree Binding

[markus7017]

Guys, there is a completely refactored binding: GREE
This is part of OH 2.5.7
