OTGW with USB doesn't work.

Maybe you have the same problem with the wifi-adapter as described in this post: http://www.domoticaforum.eu/viewtopic.p ... 189#p73174

Starting the ser2net or installing the thing and configuring it properly would do the trick. It seems that when people start resetting openwrt-images all custom stuff is removed, like the ser2net startup config. I don't have any openwrt devices so I can only guess.

Yes I think it's the same problem but the topic does not tell how to reinstall the ser2net.

And again problems so hope you can help me again. When I connect my OTGW to my laptop and use the Opentherm monitor it works fine. But when I connect it to my Raspberry pi it seems I only get half of the data.

Yesterday it worked fine and haven't changed anything since, but after a reboot of the RPi I have some trouble with my OTGW. When I power the OTGW up there is some information displayed:

But after a while there is often the message "OTGW: Error received!" displayed in the log and after that some strange messages will be displayed like:

After a while there is no message displayed anymore and the data isn't updated.
When I deactivate the OTGW in Domoticz and activate it again the same as above is applied. When I connect the OTGW to my laptop it seems to be working fine. I also added an external powered USB hub in case it might be a power problem but that doesn't help.

[hvxl]

The output you showed looks to be from some other tool, presumably Domoticz. If things work fine with otmonitor and not with Domoticz, the problem is obviously with that last program. I have no knowledge of Domoticz, so I am unable to assist with that.

And regarding the problem with ser2net, it seems to be an installable package on OpenWRT. Just try the following on the command line of OpenWRT if the program isn't installed already, or install it through the web interface:

Code: Select all

opkg install ser2net
