Opentherm Gateway platform added to 0.78.0 YEAH.... Or not?

bartandeweg · September 19, 2018, 7:03am

Yes! It’s here. The OpenThermGateway platform is added to HA 0.78.0. But i can’t get it up and running.
Probably due to one of these reasons:

I have a OTG (USB version) which uses an USB over Ethernet adapter to get connected, what worked as suspected on my VERA.
I can’t identify the right usb port

When restarting hassio i got the following two errors:

Setup of platform opentherm_gw is taking over 10 seconds.

and:

Error doing job: Task exception was never retrieved

Traceback (most recent call last):
File “/usr/local/lib/python3.6/site-packages/homeassistant/helpers/entity_platform.py”, line 342, in _async_add_entity

Anyone an idea how to proceed?

read the output of dmesg immediately after plugging it in to get the device.

I have the exact same error using serial over Ip ( Ser2Net with nodeMCU)

Cannot get it to work…

THis is my config:

climate:

platform: opentherm_gw
device: socket://nodemcuIP:serialoutputport
name: Testmostaat

It is working with opentherm monitor…

Same here, otgw from nodoshop with connected nodeMCU. Installed esp-link, correctly working through otmonitor and accessible via telnet on port 23.

bartandeweg · September 22, 2018, 6:15pm

My problem is solved. I’ve disabled bluetooth within in the confix.txt of the RPI. Switched to /dev/ttyUSB1 and it works like a boss! Did get some hints here: https://github.com/home-assistant/home-assistant/issues/16739

Hi Gaggio,

I’m also using the OTGW with NodeMCU from Nodoshop.

Did you get it working with the new platform?

gaggio · September 26, 2018, 7:01am

I actually haven’t tried anything… Didn’t find any suggestion that applies to my case yet.

Lars_Jansen · October 18, 2018, 2:10pm

Did anyone solve this yet? Also have a otgw from nodoshop with noceMCU and also accessible via otmonitor and telnet.

sander85 · October 23, 2018, 2:09pm

No, im still using OTGW connected with USB to a Pi Zero.

Martinvdm · January 7, 2019, 11:06pm

Is this working well now?

andriej · March 27, 2019, 8:43pm

It is now. Latest fixes with 0.90.2 removed most of issues.

Hi,
I have OTG connected via USB to my Vera, works great.
Now I want to switch to HA, and use the Vera integration to get my Vera devices in HA, including the temperature via OTG.
Also works great, that is, I can see the temperature, but if I want to change the temperature, this does not work.
Any Ideas about this?

bartandeweg · December 17, 2020, 7:08am

Hello @Robbie-65,

Just out of curiosity. Why still use your VERA for this and not just connect the OTG directly to your hassio and use the hassio otg integration? Works like a charm. Also for setting the temperature.

Robbie-65 · December 17, 2020, 10:38am

Hi @bartandeweg,
Good point, I am investigating this.
My OTG is a USB version, and my vera is located near the OTG. My Home Assistent is on a ESXi, that is not nearby.
But I am thinking of adding a network connection to my OTG. But my OTG is quite old, I am not sure if this would fit.

I also was a VERA user but switched over to Home Assistant totally. Best decision i made in terms of home automation.

Also i was using an old version of the OTG working on USB. I extended this USB with a ethernet extender but this was nog working very stable. I decided to build a new one with etherent on board and this runs very stable. Worth the €30.

Robbie-65 · December 17, 2020, 12:15pm

Thats good to know.
I was thinking of doing the same. but noticed that a ethernet connection is not (out of the box) possible.
Which OTG did you buy? for 30 Euro, that seems to be the best choice.

Rob

bartandeweg · December 17, 2020, 12:34pm

Take a look here: https://www.nodo-shop.nl/nl/opentherm-gateway/188-opentherm-gateway.html
I still had a spare Ethernet Module. But i think they also sell these. I used a: USR-TCP232

Robbie-65 · December 17, 2020, 4:06pm

Thanks,

Together with ethernet module and case around 50 euro.
There currently are some Tado refurbished units in discount for around 100 euro.

Maybe of topic, but I am thinking about that to.

Kind regards,

Rob
