Problems with Pentair binding

Add-ons Bindings
#1

Looking for some ideas on how to get this working. I have a USB to RS485 adapter plugged into my Raspberry Pi, running the latest version of Openhab2. It is working fine - I can run

od -x < /dev/ttyUSB1

and i see the correct binary output flowing from the device. I have added the Pentair binding and I see a Serial Bridge thing, which I have configured to use /dev/ttyUSB1. It remains in UNINITIALIZED status. I have tried to remove it so that I can add it again, and the remove just hangs. I have Force Removed it and re-added the Serial Bridge thing, but it still sits in UNINITIALIZED status.

Looking at the log after I add the Thing I see:

==> /var/log/openhab2/openhab.log <==
2018-12-30 11:48:21.470 [WARN ] [ore.thing.internal.ThingRegistryImpl] - Cannot create thing. No binding found that supports creating a thing of type ā€˜pentair:pentair_serial_bridgeā€™.

How do I fix this?

Did you add your openHAB user to the tty group

#3

No, however the openhab2 install seems to do this anyway, my zwave connectivity on /dev/ttyUSB0 works fine and the output of groups openhab shows membership of tty.

thanks

#4 
EXTRA_JAVA_OPTS

set correctly?

#5

I donā€™t know what to set it at. I have tried -Dgnu.io.rxtx.SerialPorts=/dev/ttyUSB1 and -Dgnu.io.rxtx.SerialPorts=/dev/ttyUSB0:/dev/ttyUSB1

Restarted openhab after both changes and and my zwave gets screwed up - that shows up as uninitialized too.

#6

Sorry, no idea then.

#7

thanks. I managed to get -Dgnu.io.rxtx.SerialPorts=/dev/ttyUSB0:/dev/ttyUSB1 working. zwave showed up, but the pentair binding is still uninitialized, whatever that means. And I still get this error in the log

2018-12-30 13:50:00.015 [WARN ] [ore.thing.internal.ThingRegistryImpl] - Cannot create thing. No binding found that supports creating a thing of type ā€˜pentair:pentair_serial_bridgeā€™.

Using Windows, but I have roughly the same issue with the pentair binding. I can run the node.js pool-controller binding against this exact setup, and I get all of the info, can control lights, pump, etc. I am running 2.4.0 version of OpenHAB. Is anyone successfully using this binding? I have tried configuring through paper as well as via manual things configuration.

#9

I have a Pi that is running the node.js code and it works fine. I just wanted to put everything under the openhab umbrella. However, not only does this binding not work, if you read the notes carefully it seems to be readonly, so itā€™s pretty useless even if it did work. Iā€™m going to stick with the node.js code instead.

#10

Well, I think I found one problem with the serial bindingā€¦ PaperUI configures it as pentair:pentair_serial_binding, whereas the documentation has it as just pentair:serial_binding. I have tried running it with the IP binding, using comsocketbridge (windows equivalent to ser2sock), and I donā€™t get any errors about initializing, but I also donā€™t get any useful information. Anthony, have you tried using the IP binding with ser2sock running locally?

#11

I have not tried that, seems like too much work when I have the cable from the controller right by the openhab Pi. When Iā€™m back at my house, I can try renaming the serial binding and see if that works. Will be a week or so.

#12

ok, so a year has passed and Iā€™ve now got back to looking at this!

I upgraded to 2.5.0, but I donā€™t think that was necessary. I had finally got around to using configuration files vs. PaperUI, so I created a pool.things file:

Bridge pentair:serial_bridge:1 [ serialPort="/dev/ttyUSB1" ] {
    easytouch main [ id=16 ]
    intelliflo pump1 [ id=96 ]
    intellichlor ic40
}

I had to add /dev/ttyUSB1 to EXTRA_JAVA_OPTS and also chown /dev/ttyUSB1 to root:dialout and chmod it to 666. Then this started working.

I was able to get the binding to display information about the pool, but not control it. Maybe this is because this binding is for the Pentair Easytouch and I have a Pentair Intellitouch controller.

Oh well, at least I can still use nodejs PoolController!

Did anyone get it to actually control the Pentair stuff? I can read all data, but there is no controlling it.

#14

I tried it again recently and itā€™s still read-only. Waste of time, just use node-js-poolcontroller.

#15

Sure, but it would have been nice to get it working with the binding. Is the person who did the binding reading this?

Hi Christian/Anthony - I have not been monitoring this forum. If you would like help in getting this running, let me know.

Hi Jeff, yes, I would appreciate that!

Thanks

Hi Jeff,

Iā€™m also interested in getting this up and running as a binding. I installed a TCP bridge, I can see output via netcat, and my bridge thing is online as green and so is my controller.

However, I get no numbers, and when I send a command to a switch, it doesnā€™t do anything.

Also, I have the RBG lights if a dump of that communication would be useful.

I have this up and running, and itā€™s working very well.

The developer, Jeff, has a more up-to-date version that I needed in order to get it working. Thatā€™s version 2.5.7.

Itā€™s important to note that Jeff is just some volunteer whoā€™s writing this for free. He has some pool controller setup, but he doesnā€™t have EVERY pool controller setup. That means that the community needs to help him out by sending him some logs and reports when it doesnā€™t work. That way, he can update the binding and make it better.

Hereā€™s what I did to get it running-

  • Purchased a RS-485 Bridge- https://www.amazon.com/dp/B07VWPVVNP/
  • Connected to the bridge using nc IP.OF.My.Bridge 10000 | xxd
  • Noticed no ā€œFFa5ā€ in the output, so I switched the serial lines on the bridge. For this particular controller A is Data + and B is Data -
  • Uninstalled the official OpenHAB binding, and copied the new jar from Jeff into my addons folder.
  • Things appeared in my inbox and I added them.

My EasyTouch Controller, Intelliflo, and Intellichlor were all found. The easytouch is 90% good, but it doesnā€™t read Feature Circuits yet. However it can control them. The Pump and Intellichlor are like 50% complete in their parsing and control.

The biggie though- I can control my spa, turn the lights on and off, turn the jets on and off, control the waterfall, see the temperaturesā€¦all through openhab. Thatā€™s like 99% of my use case. The rest is likeā€¦ok, let me setup an email so I know when my pool needs more salt. Thatā€™s some gravy right there, and itā€™s close, Jeff just needs more support in people sending him logs and bug reports to work out all the kinks.

What I canā€™t do yet is run a cleaning cycle from OpenHab or check my Intellichlor aside from my current salt concentration. Iā€™m sure thatā€™s coming though. Jeff doesnā€™t have all these components, so heā€™s somewhat swinging in the dark with regards to parsing them. Iā€™m actually surprised as much parses correctly as does without him having an actual device.

Is the new version installable via OpenHab? I can try it next time Iā€™m in Florida. I have a USB RS485 connector that currently plugs into my RPi running the node-js poolcontroller.
