Home Automation Domotica Forum Europe, Bwired Forum

Please point me to the topic where this was first reported, because it still doesn't ring a bell with me. I looked at your messages on the forum, but it seems your first OTGW related message was just 4 days ago. No the problem was in 2019 (tweakers.net). I couldn't get it fixed and left it for 2 ye...

The OTGW as a stand alone now works well with the ATAG E320S with separate boiler. and (only) floor heating controllers (on/off). Thank you everyone who helped me with this! The original connections have not been changed. The floor heating controller (s) are located on the on / off connection of the...

Nobody reported there was an issue with the max CH setpoint default. So it hasn't changed in firmware 5.0 and going back to firmware 4.3 will not make things worse. And I don't understand what the problem is from your description. The maximum CH temperature is a boiler setting. If the boiler is set...

There is no need to act like that is a big problem. You can easily downgrade your firmware to version 4.3. When using the Nodo Shop WiFi version of the OTGW, it is advised to use otgwmcu firmware version 0.4 on the NodeMCU. Via the built-in web interface the desired firmware version can be selected...

Maybe your thermostat does not request MsgID 26. I believe you are using the OTGW stand-alone. In that mode, the OTGW doesn't request the domestic hot water temperature by default. If you want to obtain that data, you have to instruct the OTGW to retrieve it: AA=26. This was the trick to make the t...

Of course I wouldn't suggest to connect the on/off signal to the OTGW if that wasn't supposed to work. As long as Domoticz doesn't handle the new PS=1 output, users of Domoticz should probably continue to use OTGW firmware version 4.3. I've tried this out; but then the boiler stays off and the boil...

TheSpanishInq wrote:Do you have OTGW firmware V5.0 installed? I had the same. Firmware V5.0 returns 34 values in the PS=1 report which the current version of Domoticz doesn't parse. You can find more details here.

Yes : Result = PR: A=OpenTherm Gateway 5.0

I only want to use the OTGW to monitor the boiler (ATAG E320S) in Domoticz. The (ATAG E320S) is controlled by an on / off controller of the floor heating and DHW. As far as I understand I cannot connect an on / off controller to the OTGW? When I leave the on / off thermostat on the on / off connecti...

Thank you for all your comments!

The CF-MC Master controller of the floor heating only sends an on off signal to the central heating boiler.
The room thermostats do not send a signal to the boiler but to the servomotors of the distribution units.

And I have one more question ( ).
Why are the counters not working?
Or do these not work for an ATAG E320S?

Sorry for the many questions.
I hope that later I can help someone else with my knowledge.
But why do I only get 4 devices in Domoticz?
See attachments

ATAG E320S (https://bit.ly/39ALppY)
The domestic hot water temperature thermostat is not read in the OTGW.
Is there a possibility for this?

next question: I only want to listen to the kettle (for now). The OTGW must therefore be in Monitor mode. The boiler has an on/off connection which is in use (floor heating) and an open therm connection. Do I only need to connect the OTGW to the open-therm connection? Or do I have to disconnect the ...

YEP : Successful now TNX.

Bought at the nodoshop

I want to try it through windows.

For this I changed the IP address of the PC to 192.168.0.2

And I swapped the LAN cable for a LAN cable to the OTGW module.
And then tried to go to 192.168.0.254 via the web browser.

Unfortunately this didn't work.
