Strange problem with OTGW

[Hobbybob]

That would be awesome.

I have never been able to solve the issue... Compiling it is a bit too difficult for me I think, I'm not accustomed to Linux and didn't want to risk the rest of the system.

[svkeulen]

I am working on a solution now with the developers. It will take some while though.

[Hobbybob]

No worries, everybody around here is helping where they can. I'll keep an eye out in any case.
Thanks!

edit: is there anywhere I could follow this? Like an issue on github or anything?

Yes: https://github.com/domoticz/domoticz/pull/3945

In the domoticz hardware tab of the OTGW you can issue commands. Can try sending ps=1 and see what happens?

I can try! Do I need to update Domoticz or anything first? And do I enter this command immediatly after connecting the OTGW when it is still working, or only after it starts outputting the unreadable data?

[svkeulen]

Just as soon as you connect the device. You can always switch back with ps=0.

And I have spoken to the developer. He thinks our devices will work with ps=1 'mode'. The fact that my OTGW device resets itself from time to time and domoticz will not read the data from the device isn't working. According to him it is working well for years for a lot of people. .. except for mine (which works well with ps=0 for years now ). The only difference I see is that I use a serial to USB (FTDI) connection and not the network type.

If you will try the command. Meanwhile, I will debug it a little further. (Note to myself: serial communication looks character based instead of line based output: 'thisischCOMMANDaracterdata')

[Hobbybob]

Okay, I'll try as soon as I regain access to Domoticz. I was starting on testing this out, and turned on the accept new hardware devices because I had deleted all devices of the OTGW a while back since it wasn't working anyway. However, once I saved the "accept new hardware"-option, I lost access to my control panel...

I created a speperate topic for that, as it has nothing to do with the OTGW. https://www.domoticz.com/forum/viewtopi ... =6&t=31528

[Hobbybob]

Okay, I've regained control over the control panel and I have tried the PS=1 command.

First thing I noticed was that it immediatly starts outputting the messages that start with T and B. Not the readable ones I had before. I can isue the PS=1 command, but no it does not seem to respond to that whatsoever...

I'm starting to suspect my OTGW is somehow not entirely good. Maybe my soldering was bad, or a certain part that was not 100%, I don't know. I'm thinking about buying one from someone else who doesn't need it anymore, but who knows it does work with Domoticz. Does anybody have one they are willing to sell?

[svkeulen]

That's what I expected. I'm building a binary for rpi3 right now. I will put it tomorrow on my github page. Your OTGW works just fine. It outputs the same as mine. Do you have a rpi2 or rpi3?

[Hobbybob]

I have a rpi3 (I think officially it is rpi3 model B, but I'm not sure...)

[svkeulen]

Sent you a pm.

[Hobbybob]

I received that. I can't reply however, it says you have disabled receiving PM's

[refthoom]

Maybe I overlooked something but can't you adjust the speed in the LAN module so that OTGW has more time to process incoming data?

I'm using a USR-TCP232 with baudrate at 9600 and this has been working for over two years without any errors. You could go even lower maybe, to 4800 I guess. There's not much data being exchanged.

[Hobbybob]

I also have baud-rate 9600.

At the moment I am testing the solution of svkeulen, and that seems to work really well. That would also mean that the baud-rate is not the issue, but it is a good out-of-the-box suggestion!

[eddieb]

Hi Guys,
I am trying to follow your efforts.
I bought a new OTGW just a couple of months ago and it seems to work as expected.
Also with the USR-TCP232 and it works in combination with a plugwise-anna thermostat on my remeha cv system.
running latest domoticz beta on rpi3

I noticed you are running OTmonitor at the same time in combination with domoticz.
I tried to do that but did not succeed ... When I connect OTmonitor from some windows laptop, the connection to domoticz stops and I need to power cycle most devices to get everything back in sync.

perhaps I can help in testing stuff, compiling is not my thing, sorry for that.

Eddie

[Hobbybob]

Hey eddieb! I am (currently) not running otmonitor. I use that as a means to determine where the problem lies. For example: if domoticz is not working correctly, it can be a bug in domoticz, but it can also be something on with the OTGW. That's when you use otmonitor. It the OTGW does work with otmonitor, than the OTGW is probably okay.

Running 2 pieces of software on the OTGW is not a good idea. If you want to run both, you should enable remote access in otmonitor, and then point domoticz to otmonitor. That way otmonitor is the only one that actually connects to the OTGW, but it will relay all messages to and from Domoticz.

[eddieb]

tnx @Hobbybob ,
Running 2 clients on the OTGW gave me much problems so I stopped trying that within the 1st day I had my OTGW running.

It runs fine for almost 2 moths now and I am very happy with it.
Had some issues with the PlugWise Anna / Smile but after I was helped by the plugwise helpdesk to get the latest firmware that works stable to.
I van control the boiler in different ways :
- domoticz -> OTGW
- domoticz -> ANNA plugin
- Anna/Smile webinterface
- Plugwise app
